There are infrared LED wavelengths on the market, such as 730nm, 810nm, 830nm, 870nm, and 905nm IR LED. However, the most common ones are 850nm IR illuminators and 940nm infrared LED lights, which differ from each other in various ways. So here, we will compare these two infrared LED lights. Please read on.

Ultrasound of the scrotum with duplex showed increased vascularity of the enlarged left epididymal tail, concerning for epididymitis as seen in Figure 2. There was soft tissue swelling of the scrotum that was worse on the right. Additionally, mobile echoes within the edematous scrotum were seen for which an unencapsulated complex fluid collection such as abscess or hematoma could not be excluded. There was no sonographic evidence of soft tissue gas, ruling down the possibility of gas gangrene. Cultures of the wound revealed massive growth of two strains of gram-negative rods and heavy growth of gram-positive cocci.

Patients who present with a longer duration of entrapment and who use non-metal objects more frequently experience higher grade penile injuries with diminished recovery and less favourable outcomes [3]. Also, physicians often have to be resourceful when removing the penile ring, often relying on tools available in the maintenance department of their hospital, which may not be optimal.

This case emphasizes the importance of prompt treatment with removal of the ring and the initiation of broad-spectrum antibiotics in any patient with a similar localized injury sustained over days.

Penile and scrotal incarceration by a metal ring is a rare urological emergency that requires immediate removal of the strangulating object to avoid severe clinical consequences. Metal rings are used to enhance sexual activity. Here we present a case of penile and scrotal entrapment in a young patient who presented three hours after removal with fever and pain. Before removal, the ring had remained in place for over 48 hours. This case highlights the importance of prompt treatment of these patients as complications such as gangrene can occur if not treated expediently.

Urology was consulted who recommended continuing broad-spectrum antibiotics with no surgical intervention recommended. The infectious disease team was also consulted, and they suggested to broaden antibiotic coverage to cover anaerobes by adding metronidazole. Over the next week, the patient made a full recovery with no residual sensory or functional deficits. He was discharged on oral and topical antibiotics.

Rings placed around the penis and scrotum are used to restrict blood flow to increase sexual performance. Penile entrapment related to excessive constriction of the tissue can occur, causing progressive edema, ischemia and if left untreated gangrene [1]. This case highlights the potential complications of penile ring entrapment in this young patient with delayed treatment. In cases involving penile rings, patients often delay seeking care due to the sensitive nature of their issue. There have been a few cases reported in the literature of patients with resultant sepsis from penile ring injury with a couple of reports resulting in the death of the patient [3,4].

l 850nm infrared LED: Given the advantages in extended coverage and camera sensitivity, the 850nm wavelength is generally the best choice for most security applications, face recognition, automobile sensor, and 3D sensor. However, it is not suitable for covert surveillance applications because it emits a slight red glow.

Penile rings are used to enhance sexual function by constricting the outflow of blood from the corpus cavernosum, which prolongs erection. However, penile rings can lead to genital incarceration if left on for over 30 minutes [1]. Penile ring entrapment is considered a urological emergency with potentially severe clinical consequences, including death if left untreated [1,2].

Now that you can tell the differences between 850nm and 940nm infrared LED, it's time to get premium products from a reliable IR LED supplier. Among many LED light suppliers on the market, It's time to get premium products from a reliable IR led supplier. Among many led light suppliers on the market, Refond stands out. Here are what we can offer if you choose our 850nm and 940 infrared LED light products.

Penile incarceration has been described in the literature through sporadic case studies and has affected a wide range of age groups. The most frequently used penile rings causing incarceration are metal rings, although non-metal rings have also been reported to cause an injury that is often more severe. Penoscrotal rings are used less frequently in sexual practices but can cause significant injury if entrapment occurs. Emergent removal is necessary, and delay in treatment may result in edema, tissue injury, necrosis or eventual gangrene [1].

He returned three hours later, that same morning with complaints of a fever, sweats, nausea, chills, and muscle fatigue. He denied respiratory symptoms, dysuria, abdominal pain, nausea, vomiting. On physical examination, the patient appeared to be in moderate distress. Presenting vital signs were as follows: temperature 39.5°C, heart rate 126, respiratory rate 20 breaths per minute, blood pressure 142/68 mmHg, O2 saturation on room air of 98-100%. The genitourinary examination was significant for severe edema over the body of the penis and testicles, as seen in Figure 1. Over the area where the annular penile constrictor was placed, there was some skin maceration and minor purulent discharge. Sensation in the penile and scrotal area remained intact. There were no signs of surrounding cellulitis. Cardiac, respiratory, and abdominal examinations were unremarkable. The patient was admitted and started on intravenous cefepime and vancomycin along with topical bacitracin. The patient had a mildly elevated white blood cells count with neutrophilic predominance, normal lactic acid level. HIV antigen and antibody test was reactive with a CD4 count of 854. The patient's liver enzymes were moderately elevated, likely due to untreated hepatitis C. The rest of the patient's laboratory results are detailed in Table 1.

A 28-year-old man with a past medical history of HIV, hepatitis C (untreated), and secondary syphilis presented to the emergency department with complaints of new-onset fever, plus penile and testicular swelling for the past 72 hours. The previous day he had visited the emergency department because he was unable to remove a metal ring that he had placed around the base of his penis and scrotum two days earlier. He had been able to urinate with a normal urinary stream. The patient's past medical history included HIV diagnosed 2011, hepatitis C diagnosed in 2018, and secondary syphilis. The patient also had a history of tobacco and methamphetamine use. He was afebrile, tachycardic with a heart rate of 109 beats/minute, with a blood pressure of 141/115 mmHg. Attempts to pull off the ring with lubrication were futile, and the ER team subsequently split and removed the ring with an electric saw. The patient was discharged early in the morning with plans for urology follow up and sent home with a prescription for cephalexin 500 mg four times a day for seven days.

Penile ring entrapment is a rare, urological emergency that can lead to severe consequences such as gangrene or even penile amputation if not promptly treated. A rapid removal of the constricting device is of the utmost importance and can require an inventive approach. While most patients do well without additional interventions, it is essential to initiate antibiotic treatment and closely monitor patients to prevent ischemia, necrosis, gangrene or systemic complications. Another critical takeaway point from this case is the emphasis on patient education regarding safe sexual practices.

It is important to consider their differences when purchasing 850nm or 940nm IR controllers for LED lights. Power consumption, illumination distance, and performance (such as water resistance, anti-dust, etc.) should also be considered when choosing 850nm or 940nm IR lights. But overall, these 850nm and 940nm infrared LED lights have their advantages and should be chosen based on your project.

l Red glow: 850nm infrared LED gives off a slight red glow at the LED light source and can be noticed if closely observed. However, the 940nm IR illuminator is completely invisible, meaning that there is no light on the surface of the red light, and is more hidden.

l Radiation intensity: The radiation intensity of the 850nm infrared LED is about two to three times higher than that of the 940nm IR light.
