Description

Liquid absorption mechanism and dressing for preventing liquid leakage from puncture site

Technical Field

The utility model relates to the technical field of medical devices, in particular to a liquid suction mechanism and a patch for preventing liquid leakage from a puncture site.

Background Art

According to clinical needs, catheter drainage is often performed after thoracocentesis. Over time, the drainage tube cannot fit tightly against the skin. When the drainage tube is removed, a gap is formed in the skin around the puncture site, which can cause serious fluid leakage. Currently, the dressings to prevent fluid leakage from the puncture site are mainly made of waterproof or absorbent materials.

However, in actual operation, the common dressing absorbent mechanism on the market cannot fully absorb the leaked body fluids, resulting in the outflow of body fluids and soaking of clothes and bed sheets. Doctors have to repeatedly disinfect and change the skin around the puncture site; and the existing dressings need to repeatedly tear off or stick tape when changing the absorbent material or medicine, causing secondary damage to the patient's wound. Therefore, the problem of puncture site liquid leakage not only brings serious psychological, social and economic burdens to patients, but also increases the workload of clinicians and causes waste of medical resources.

Example 1

1-2 , which are the first embodiment of the present invention, provide a liquid suction mechanism, including a connecting unit 100 and a liquid suction unit 400 .

Among them, the connection unit 100 includes an adsorption component 101, a connection plate 102 arranged on the adsorption component 101, and an adhesive sheet 103 fixedly connected to the lower surface of the adsorption component 101, wherein a drainage port 101b is provided on the upper surface of the adsorption component 101, and a connection groove 1 101c is also provided on the lower surface of the adsorption component 101; the liquid absorption unit 400 includes a polymer component 401 arranged on the adhesive sheet 103, and a liquid absorption component 402 arranged on the polymer component 401, wherein a connection groove 2 401b is provided on the polymer component 401, and the portion of the adhesive sheet 103 protruding from the connection groove 1 101c is fixedly connected in the connection groove 2 401b.

During use, the entire dressing is adhered to the patient's wound through the connecting unit 100 until the wound is fully healed. During this period, any replacement of the absorbent material or medicine does not require the entire dressing to be torn off, so it will not repeatedly cause damage to the skin near the patient's wound. The leaked body fluid can be collected by the absorbent unit 400, and then the absorbent material can be replaced by simple picking and placing, avoiding the complexity of the operation and reducing the workload of medical staff.

Example 2

1-2, which is a second embodiment of the present utility model, which is different from the first embodiment in that the adsorption component 101 includes a soft magnetic sheet 101a fixedly connected to the bottom of a connecting plate 102, an adhesive sheet 103 is embedded in a connecting groove 101c, and the connecting plate 102 is movably connected to the soft magnetic sheet 101a.

During use, the connecting disk 102 mainly plays a connecting role, connecting other units and components and providing a hub, while the soft magnetic sheet 101a is used to provide adsorption force to facilitate the adsorption of the magnetic components behind, so that the components that need to be repeatedly replaced can be firmly connected to the connecting disk 102 even without fixation; the function of the adhesive sheet 103 is to fix the connecting unit 100 on the skin to prevent the entire patch from falling off; the drainage port 101b is used for drainage, guiding the leaked body fluids into the designated area for absorption, to prevent the leaked body fluids from contaminating clothes or bed sheets, etc.

Compared with the first embodiment, further, the polymer component 401 includes a liquid collecting chamber 401a disposed on the adhesive sheet 103, a second connecting groove 401b is disposed on the liquid collecting chamber 401a, and the adhesive sheet 103 is embedded in the second connecting groove 401b.

Furthermore, the liquid absorbing assembly 402 includes a liquid absorbing member 402a disposed on the liquid collecting chamber 401a, and a brim 402b disposed on the liquid absorbing member 402a.

Preferably, the liquid absorbent member 402a is fixedly connected to the brim 402b, the liquid absorbent member 402a is embedded in the liquid collecting chamber 401a, and the brim 402b is attached to the liquid collecting chamber 401a.

During use, the liquid collecting chamber 401a is tightly connected to the soft magnetic sheet 101a, so the body fluid drained from the drainage port 101b will flow into the liquid collecting chamber 401a, and then be absorbed by the liquid absorbent piece 402a in the liquid collecting chamber 401a. After absorbing for a period of time, the medical staff lifts the brim 402b with their fingertips to take out the liquid absorbent piece 402a for replacement, keeping the liquid collecting chamber 401a dry while absorbing more leaked liquid. The adhesive sheet 103 embedded in the connecting groove 401b can stably connect the liquid absorbent unit 400 to the patient's skin, so that it can work normally.

The remaining structures are the same as those of Example 1.

Example 3

1 to 4 , which are the third embodiment of the present utility model, a patch for preventing liquid leakage from a puncture site is provided, comprising the above-mentioned liquid absorption mechanism.

During use, the entire dressing is adhered to the patient's wound through the connecting unit 100 until the wound is fully healed. During this period, any replacement of the absorbent material or medicine does not require the entire dressing to be torn off, so it will not repeatedly cause damage to the skin near the patient's wound. The leaked body fluid can be collected by the absorbent unit 400, and then the absorbent material can be replaced by simple placement, avoiding the complexity of the operation and reducing the workload of medical staff.

It also includes an installation unit 200 and a compression unit 300; the installation unit 200 includes a fitting component 201 and a pressing component 202 arranged on the fitting component 201, wherein the fitting component 201 is provided with a fitting groove 201b; the compression unit 300 includes a medical cotton pad 301, a compression component 302 arranged on the medical cotton pad 301, and a protective component 303 arranged on the compression component 302, wherein the protective component 303 is provided with an air hole 303c.

During use, the engaging sheet 201a, the connecting plate 102 and the soft magnetic sheet 101a are connected into a whole through the magnetic attraction effect of the soft magnetic ring 202a and the soft magnetic sheet 101a. The anti-slip sheet 202b can prevent the engaging groove 201b from falling off by adding multiple corner designs. At the same time, the soft magnetic ring 202a can also absorb the sealing ring 303a to form a closed space to prevent external bacteria from entering through the gap and infecting the wound. The medical cotton pad 301 can be more closely connected to the wound under the squeezing of the airbag 302a, thereby helping the wound to heal faster. The air nozzle 302b is used to inflate or deflate the airbag 302a, thereby controlling the pressure applied by the airbag 302a to the medical cotton pad 301.
