Example (b): isolating device for scabies nodule cryotherapy

Scabies are contact infectious skin diseases caused by scabies in the epidermis layer of human skin. Popularity can be spread between homes and contacters. The clinical manifestations are characterized by that the skin is tender, and pimples, blisters and tunnels are formed, and dark red scabies nodules with the size of bean grains can occur in the external genitalia such as scrotum, and the pruritus is aggravated at night.

In treatment, the patient does not have a bath and does not change clothes during the medication period. However, scabies present a more common problem with external genital nodules, which are particularly difficult to avoid in nodular and bullous scabies.

Explanation: nodular scabies

Nodular scabies are 2-20 mm in diameter with severe itching, and are good at male genitals, buttocks, groin and axilla (see fig. 5). The nodule is reddish brown without scabies, and is caused by a strong hypersensitivity reaction of the local skin to scabies products. It may last for several weeks after treatment of scabies, and some patients need to be treated with injections of glucocorticoids.

Explanation: bullous scabies

Bullous scabies are rare, lesions appear similar to autoimmune blistering diseases, and stressful blisters are most commonly found in the arms, legs and trunk, and can also develop systemically, with rare sites including genitals, groin, thighs, buttocks, neck and feet. Lesions not only mimic bullous pemphigoid clinically, but even histologically, as evidenced by subcutaneous blebs with eosinophil infiltration.

Liquid nitrogen cryotherapy is common clinically in the treatment of nodules. Liquid nitrogen is a liquid at-196 ℃, and the treatment process is to destroy the focus of the skin by utilizing the freezing effect of the liquid nitrogen, so that the nodules fall off. Is very effective for scabies nodules. The skin damage is small, scars are not easy to remain, a cotton swab is usually dipped or sprayed clinically, and the cotton swab contact method is more used in our hospital because the skin is thinner, so that the acting area is smaller and is easier to control. But also by spraying. (details are described later)

Since 2010, 532 scabies patients were treated by cryotherapy. The effect is better. There are many areas of major attention in the middle and late care of the treatment of scabies nodules using this procedure:

1) in the treatment, the cryotherapy inevitably causes skin damage and pain because the therapeutic principle is to cause necrosis and detachment of the nodules. Patient compliance is required to address the freezing process and possible side effects for patients requiring cryotherapy.

In a more specific case, the skin of the scrotum and penis (as shown in fig. 1 and 2, the figure is a partially enlarged view of the nodule part and typical but not serious symptoms in order to avoid discomfort), the skin is thin, the fold body hair is more, and the skin near the nodule is required to be fully exposed to make enough space for operation in order to avoid damage to other surrounding normal skins during treatment.

Meanwhile, because the organ has no self-support, the organ can be vertically applied, and the patient has limited coordination due to factors such as pain and the like. Therefore, even if the position is very narrow, two persons are often needed to assist each other, the control is difficult, and other nearby epidermis is easy to be injured by mistake.

2) In the care phase after treatment.

Mainly pay attention to the suspension, isolation, dryness keeping and cleanness of the local area to be treated.

Since blisters may form hours after treatment and may persist for several days, this is a normal response. The self-healing can be achieved within 15-20 days generally. However, care should be taken to protect the bleb, which itself is filled with tissue fluid, to avoid rupture, and to keep it as dry as possible, although this is difficult at this point and extra care should still be taken to minimize healing time and prevent secondary inflammation and infection.

Similarly, after the blister wound surface scabs, attention should be paid to avoiding and preventing friction, and the blister wound surface should fall off naturally as much as possible.

However, since the organs are naturally attached together in a hanging manner, not only local moisture is caused, but also the organs rub against each other, which easily causes blister rupture, and increases nursing troubles and secondary infection. Therefore, the postoperative care is not only a trial for the patience and care of medical workers, but also a trial for patients. However, even if the body posture, the frequent ventilation (airing) and the isolation by using gauze are noticed, the bubbles are easily broken, a lot of troubles are brought to the nursing, and the probability of secondary infection is high.

In addition, although the contact method is commonly used in the department of China, the spraying method is selected according to the severity of diseases, and other mechanisms are known to be commonly used for the private parts, because the contact method has shallow effect, and along with the popularization of the health and medical level, people can seek medical treatment in time, and the condition of the nodule is not serious generally. But if the nodule protrusions are obvious and the nodule is heavy, only the spray method can be selected. The spraying method is more preferable to the surface unevenness of local tissue than the contact method. However, since it uses a spray gun to spray directly to the lesion site in the form of mist, the spray distance, range, and surrounding tissues must be protected and isolated by strict control. Thus, isolation protection is more important for this method of male scrotum placement.

The example is used as an isolation device for scabies nodule freezing treatment, which mainly has the functions of carrying out partition isolation on each part of epidermis of male lower vagina part and also can support and change the relative position of each organ to make room for operation. The main structure is specifically as follows:

comprises a waist-binding belt 1, leg-binding belts 2 and a spacing block.
