Disposable external hemostatic device

technical field

The utility model belongs to the field of medical equipment, and relates to a disposable external hemostatic and liquid stopper.

Background technique

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:

1. Dressing replacement: It is one of the most traditional and widely used methods in clinical practice. Traditional dressings include basic materials such as gauze, cotton pads, and bandages. Mainly by changing the wound dressing frequently, keep the wound dry until the wound heals. Due to wound bleeding and exudation time is not fixed, it is often obvious when the patient changes position, and clinicians cannot change the dressing in time due to heavy workload and many things. Wounds with continuous exudation not only easily lead to infection, but also make patients feel clammy and dirty. At the same time, because the wet wound dressing has poor viscosity and is easy to fall off, patients dare not change positions at will, and the body is in a stiff state, which not only affects the Patients are also prone to pressure sores while resting, and frequent dressing changes increase the workload of medical staff and the economic burden of patients.

2. Ostomy bag: This method can drain the extravasation into the ostomy bag, avoid the extravasation from contaminating the patient's clothes and sheets, reduce the workload of the medical staff, and make the patient feel relatively comfortable. However, this method cannot solve the fundamental problem of wound exudate. Extravasation will ooze out at any time due to the patient's changing position. Long-term exudate not only increases the psychological burden of patients, but also easily leads to infection of patients.

3. Liquid glue (ear brain glue): The medicine should be used in time after opening, otherwise it will solidify naturally. It is a disposable consumable product with a large specification, but the dosage is not much, only a few drops each time, the remaining amount is easy to waste, and the price is expensive, and it is not covered by medical insurance. When the drug sticks to the wound, because it is a liquid structure, it is not easy to be controlled, and it tends to stick to the surrounding skin, especially in the skin folds, which easily leads to the adhesion of the upper and lower skin and is difficult to separate. For patients with liver cirrhosis and refractory ascites, due to the continuous seepage of the puncture site, the liquid glue is often diluted by ascites or lost with ascites oozing before the liquid glue becomes solid, and the hemostatic effect is not ideal .

4. Rubber stopper: It is a small technique used clinically. Align the soft rubber stopper with the wound, then press the top of the rubber stopper, fix the soft rubber stopper with medical paper glue when the rubber stopper rebounds, take it off after about 48 hours, and check the wound healing. This method is simple and practical, and the effect is obvious, but there are many shortcomings. First, proper fixation of the rubber stopper is problematic because the location of the wound varies from patient to patient. The rubber stoppers for wounds adjacent to the joints are often not easy to be fixed, have poor sealing performance, and are prone to leakage of blood and body fluids. For parts that are often rubbed, even if they are properly fixed with paper glue, the rubber stopper is prone to shift or slip when the patient inadvertently touches or changes positions, resulting in leakage of blood and body fluids. Repeatedly fixing with paper glue for a long time may easily cause skin damage of the patient. Secondly, because the rubber stopper is made of opaque material, the healing of the wound cannot be seen with the naked eye. Based on experience, the rubber stopper can only be removed in about 48 hours to check the wound healing, and then decide whether to continue the treatment. 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, the rubber stoppers are local materials without strict disinfection treatment, which can easily lead to wound infection.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a disposable external hemostatic device, which is composed of a semicircular bottom, a hollow cylinder with openings at both ends, a one-way valve and a wide edge containing glue , the semicircular bottom is a spherical cut surface, the lower end of the cylinder is connected to the opening of the semicircular bottom, the upper opening of the cylinder is connected to a wide edge containing glue, and the one-way valve is set on one side of the cylinder. After the air is sucked from the outside, 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. There is a protective paper on the wide edge with adhesive.

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

The utility model has the following advantages: (1) The healing condition of the wound can be clearly seen by using transparent materials, and the treatment time is determined according to the degree of wound healing. At the same time, it can also observe the changes of the wound and its surrounding skin, so as to avoid the occurrence of skin pressure sores or necrosis. The soft latex material can be properly deformed to adapt to the touch of the human body, and the small size is convenient for patients to manage themselves. (2) The one-way valve design can adjust the air pressure state in the device at any time. The air is sucked, and the device is in a negative pressure state, which promotes the growth of capillaries by forming a local hypoxia state, and increases the oxygen content of the local wound. At the same time, the negative pressure forms a natural physical pulling force on the edge of the wound, which will promote the division and reproduction of fibroblasts, accelerate the crawling of the epidermis, and accelerate wound healing. When the air is sucked, the skin of the wound is pulled outward, the wound is closed, and the fluid no longer seeps out. (3) The waterproof adhesive film attached to the wide edge can be in good contact with the patient's skin, and can be well adhered even to the joints, which is convenient for medical staff to operate. The waterproof design can also avoid the occurrence of blood and body fluid leakage. This wide edge design not only ensures the firmness of the paste but also maintains the integrity of the patient's skin. (4) Sterilized and individually packaged with ethylene oxide to prevent infection caused by device problems. (5) Devices of different shapes and specifications can also be designed according to common clinical wound types.

Fumbull, an American ostomy therapist, proposed to improve the quality of life of patients. Patients should not only live, but also live happily and with dignity. Under the guidance of this concept, this device upgrades wound care to patient quality life care. The utility model has the advantages of reasonable design, small size, low cost, no influence on patients wearing clothes and quilts at all, more humane advantages, not only saves health resources, but also improves the quality of life of patients, and the materials are cheap, and the effect is obvious. Reduced hospital costs and improved patient satisfaction.

Embodiment 2 usage method

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

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.

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

The use of the utility model reduces the economic burden of the patient, and excessive exudation leads to frequent dressing changes, which 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 increases the labor intensity of the medical staff. It will affect the blood circulation of the extremities and the growth of granulation tissue. If it is too loose, it will easily cause the dressing to fall off and cause pollution. After using this device, due to the characteristics of the selected materials, the airtight moisturizing dressing has strong self-adhesiveness, no irritation and no allergic reaction to the skin, it is waterproof, and allows water vapor to pass through, but does not allow liquid water to pass through. Free bathing.

The utility model promotes the growth of capillaries by forming a local anoxic state, and improves the local oxygen content of the wound. At the same time, the negative pressure forms a natural physical pulling force on the edge of the wound, which will promote the division and reproduction of fibroblasts and accelerate the crawling of the epidermis. In addition, because the exudate is removed by the suction tube in time, it is not easy to cause impregnation of the tissues around the wound, which reduces the number of dressing changes and brings convenience to both patients and medical staff.
