Problems solved by technology

As a result, it is not only impossible to correctly judge the wound healing situation, but also the skin necrosis around the wound may not be discovered due to long-term compression
Furthermore, rubber stoppers are made from local materials without strict disinfection treatment, which can easily lead to wound infection

Embodiment 1

[0014] see figure 1 , a disposable external hemostatic device, composed of a semicircular bottom 1, a hollow cylinder 2 with both ends open, a one-way valve 3 and a wide edge 4 containing glue, the semicircular bottom 1 is a spherical cut surface, The lower end of the cylinder 2 is connected to the opening of the semicircular bottom 1, the upper opening of the cylinder 2 is connected to a wide edge 4 containing glue, and the one-way valve 3 is set on one side of the cylinder 1, and the air is sucked outward through the syringe Finally, the valve can be automatically closed to prevent air circulation and maintain the internal negative pressure state. The device is shaped like a round sun hat with a broad brim. A layer of protective paper is pasted on the wide edge 4 containing glue.

[0015] The device material is made of transparent latex or silica gel. The entire unit is packaged sterile with ethylene oxide.

Embodiment 2

[0016] Embodiment 2 usage method

[0017] Step 1: Disinfect the patient's wound and wait for it to dry;

[0018] Step 2: Tear off the adhesive protective paper on the wide edge 4 of the device, align the center of the device with the patient's wound, and lower it slowly so that the wide edge 4 sticks to the skin. Do not pull the skin around the wound, so that the skin is naturally loose state, keep the pasted edges flat.

[0019] Step 3: Use a syringe to suck air from the outside of the one-way valve 3.

[0020] The use of the present invention reduces the economic burden of the patient, excessive exudation leads to frequent dressing changes, increases the cost of treatment and dressing, is also prone to concurrent infection, and increases hospitalization time and expenses. If the patient needs to change the dressing frequently, according to the current practice, it is time-consuming and expensive, which not only increases the economic burden of the patient, but also increas...

Abstract

The invention provides an externally-used disposable bleeding and fluid effusion stopping device. The device comprises a semi-circular bottom, a cylindrical cylinder with two open ends, a one-way valve and a wide edge containing adhesive, wherein the semi-circular bottom is a special section; the lower end of the cylinder is connected with an opening of the semi-circular bottom; the upper opening of the cylinder is connected with the wide edge; the one-way valve is arranged on one side of the cylinder. According to the device, growth of blood capillaries is promoted through formation of a local hypoxic state, and the content of oxygen in a part of a wound is increased. Natural physical pulling force is applied to the edge of the wound under negative pressure, can promote fissiparity of fibroblast and accelerates epidermis creeping. Besides, maceration of tissue surrounding the wound is unlikely to be caused due to the fact that effusion is removed through a sucking pipe in time, the number of times for dressing is reduced, and convenience is brought for patients and medical workers. The device is reasonable in design, simple to manufacture and low in cost.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to a disposable external hemostatic and liquid stopper. Background technique [0002] In clinical nursing work, it is often encountered that patients have continuous bleeding and exudation from wounds due to various reasons such as changes in the condition or postoperative complications, such as wound exudation after drainage tube removal, exudation after central venous catheter extubation, etc. Wait. Continuous wound exudation not only increases the patient's discomfort and weakens the patient's confidence in treatment, but also increases the workload of medical staff and even causes medical disputes. Currently, there are various methods of hemostasis and hemostasis commonly used in clinical practice, but they are effective and inexpensive Lian never showed up. Specifically explain the commonly used hemostasis and hemostasis methods in clinical practice: [0003] 1. Dressing rep...
