Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a wound flushing, negative pressure suction and collection device. Background Art

[0002] Surgical incision infection and dehiscence are common complications after surgery, especially for large incisions after laparotomy for digestive tract tumors such as the gastrointestinal tract, liver, gallbladder, and pancreas. Complications of anastomotic leakage can easily cause local and systemic symptoms, abdominal infection, peritonitis, etc., further aggravating the patient's condition, prolonging hospitalization time, increasing medical costs, and aggravating the patient's pain.

[0003] At present, for severe incision infection and exudation, VSD negative pressure suction devices are mainly used clinically for adequate drainage. However, most drainage devices can drain exudate well, but are not very effective in draining larger necrotic tissues, and the sponge and drainage tube opening are easily blocked by the accumulated tissues, thus losing the drainage effect.

[0004] To this end, the present invention aims to provide a wound irrigation, negative pressure suction and collection device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and to provide a wound flushing, negative pressure suction and collection device. By covering the interlocking cover plate on the adsorption base plate, negative pressure is formed in the device, and then the patient's wound is flushed in all directions through multiple secondary flushing tubes, which speeds up the wound healing time and reduces the pain of the patient; and the large-diameter recovery groove can prevent the accumulated tissue from being drained from clogging the sponge and the drainage tube opening.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] The present invention provides a wound irrigation, negative pressure suction and collection device, the device comprising an adsorption base plate and a chimeric cover plate;

[0008] The adsorption chassis is a hollow cuboid with an open top, the side of the adsorption chassis in contact with the liquid is the inner side of the adsorption chassis, and the side not in contact with the liquid is the outer side of the adsorption chassis;

[0009] A C-shaped main flushing pipe is embedded inside the adsorption chassis, and a plurality of secondary flushing pipes are arranged on the side wall of the C-shaped main flushing pipe. A liquid outlet is arranged on the top of one end of the secondary flushing pipe that is not connected to the C-shaped main flushing pipe;

[0010] A plurality of support columns are arranged inside the adsorption chassis body;

[0011] A retaining groove is provided at the top of the outer side wall of the adsorption chassis body, a plurality of fixing buckles are provided on the top side wall of the retaining groove, and a first sealing strip is provided at the bottom of the retaining groove;

[0012] A cutting area is provided at the center of the inner side of the adsorption chassis body;

[0013] The embedded cover plate is a hollow cuboid with an opening at the bottom. A second sealing strip is provided at the bottom of the embedded cover plate, and a plurality of fixing grooves are provided at the bottom of the inner wall of the embedded cover plate.

[0014] In this solution, the interlocking cover plate is covered on the adsorption bottom plate to form a negative pressure in the device, and the C-type main flushing pipe is connected and communicated with the secondary flushing pipe, so that the liquid entering the C-type main flushing pipe can enter the plurality of secondary flushing pipes through the C-type main flushing pipe, and then enter the inner side of the adsorption bottom plate of the device through the liquid outlet, so as to flush the wound exposed in the cutting area and promote wound healing;

[0015] The support columns inside the adsorption chassis are used to support the cover plate to prevent it from collapsing during adsorption. The support columns are spaced at a certain distance, and liquid and necrotic substances can flow between the support columns;

[0016] After the interlocking cover plate is covered with the adsorption bottom plate, a closed environment is formed in the device under the action of the first sealing strip and the second sealing strip.

[0017] The opposite end of the C-shaped main flushing pipe connected to the secondary flushing pipe is provided with a liquid inlet pipe, and the liquid inlet pipe extends from the inside of the adsorption chassis through the thickness of the side wall of the adsorption chassis to the outside of the adsorption chassis body;

[0018] A recovery groove is provided on one side of the adsorption chassis, and the recovery groove extends from the inner side of the adsorption chassis body through the thickness of the side wall of the adsorption chassis to the outer side of the adsorption chassis body.

[0019] The C-shaped main flushing pipe is embedded in the adsorption chassis and surrounds the three adjacent side walls of the adsorption chassis;

[0020] The recovery tank is arranged at one end of the attached chassis where the C-shaped main flushing pipe is not arranged;

[0021] The liquid inlet pipe is arranged on a side opposite to the recovery tank.

[0022] In this solution, the C-type main flushing pipe is connected to the liquid inlet pipe, and the liquid inlet pipe is connected to the flushing liquid, so that the liquid flows into the C-type main flushing pipe under the action of negative pressure, and then flows into several secondary flushing pipes from the C-type main flushing pipe to flush the patient's wound. After the flushing, the waste liquid and wound exudate are discharged through the recovery tank connected to the adsorption chassis, and flow into the waste liquid bottle connected to the recovery tank.

[0023] The liquid outlet connects the inner side of the adsorption chassis body with the inner side of the secondary flushing pipe.

[0024] In this solution, by connecting the inner side of the adsorption chassis body with the inner side of the secondary flushing tube through the liquid outlet, the liquid inside the secondary flushing tube can enter the inner side of the adsorption chassis body through the liquid outlet to flush the wound exposed in the cutting area, and by arranging the secondary flushing tube in multiple directions, the wound can be fully flushed when flushing the patient's wound, thereby accelerating wound healing.

[0025] The plurality of secondary flushing pipes are arranged at equal intervals, and a plurality of support columns are disposed between each adjacent secondary flushing pipe.

[0026] In this solution, the support column is a pillar with a length, width and height of 1 cm each, which is used to support the cover plate to prevent collapse during adsorption. The support columns are spaced a certain distance apart, and liquid and necrotic substances can flow between the support columns.

[0027] Compared with the prior art, this solution has the following beneficial effects:

[0028] 1. The waste liquid bottle connected to the recovery tank can enable the device to directly discharge the waste liquid and wound exudate washed through the patient's wound through the recovery tank under negative pressure, solving the problem that the common negative pressure drainage device is difficult to drain large necrotic tissue and easy to block the drainage tube;

[0029] 2. The adsorption base and the embedded cover are covered to form a closed negative pressure space, and the embedded cover is detachable, which is convenient for medical staff to check the wound status at any time, so that medical staff can adjust the treatment plan according to the wound status;

[0030] 3. By equidistantly arranging several secondary flushing tubes in the device, the patient's wound can be fully flushed, and then through the synergistic effect of negative pressure, flushing and suction, the wound exudate can be quickly attracted, reducing the patient's pain and promoting wound healing; avoiding the patient from undergoing another surgery or alleviating the patient's more serious complications caused by infection.
