Description

Technical Field

[0001] The invention belongs to the technical field of medical care, and in particular relates to an anti-seepage drainage device for abdominal surgery. Background Art

[0002] Dressings are medical materials used to bandage surgical wounds or traumatic wounds to prevent wound infection and dehydration, provide an environment conducive to wound healing, and promote wound healing.

[0003] When patients with a large amount of ascites undergo abdominal puncture and catheter drainage, after the ascites drainage tube is removed, the drainage port often leaks a lot of fluid, causing the dressing to be filled with water and leak out, contaminating the patient's clothes and bed sheets, and the dressing or clothes and bed sheets need to be changed frequently, which is time-consuming and labor-intensive, and has low work efficiency. Therefore, the commonly used dressings are completely unable to meet the function of absorbing exudate all the time.

[0004] Chinese patent CN213758786U discloses an anti-leakage device for postoperative abdominal puncture, which belongs to a surgical auxiliary device, including an adsorption seat, a negative pressure cavity is formed between the adsorption seat and the human skin, a one-way valve for extracting air from the negative pressure cavity is provided on the adsorption seat, and an anti-seepage plug for blocking the wound is provided in the adsorption seat; by using an air extraction device, such as a syringe barrel, etc. to extract air into the negative pressure cavity, a negative pressure environment can be formed in the negative pressure cavity, so that the adsorption seat is sucked on the human skin, and at the same time, the anti-seepage plug can block the wound to prevent ascites from leaking from the wound. At the same time, the negative pressure environment will also pull the skin tissue near the wound to accelerate its healing, thereby solving the problem of lack of effective postoperative anti-leakage means in the prior art and poor clinical effects of conventional pressure bandages and abdominal belt compression.

[0005] The above patent helps the puncture site to heal quickly by forming a negative pressure environment outside the puncture site, and cleans the exuded ascites to avoid forming a humid environment in the negative pressure cavity. However, the material of the deformed portion is a flexible material, and the anti-seepage plug is directly aligned with the puncture site. The weight of the leakage device will press on the wound, causing discomfort or even pain to the patient, and the sterile pad will accumulate at the bottom of the negative pressure cavity after the ascites seeps out. Without drainage, bacteria are easily bred, causing wound infection and worsening the patient's condition. Summary of the invention

[0019] Preferably, a latch is provided between the base and the other side of the seat cover that is rotatably connected.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The anti-seepage drainage device of the present invention has suction cups arranged around the base to prevent liquid from flowing out, and a dressing assembly and a drainage tube are arranged. When in use, the dressing is used to absorb liquid exuded from the wound. Because the bottom surface of the dressing is arranged in an arc shape with a middle high and two side lows, after the liquid is absorbed, the liquid absorbed in the medicine will flow into the sponges on both sides and will not be soaked due to excessive wetting, thereby achieving the effect of keeping the wound part corresponding to the medicine moist, which is beneficial to wound healing; further, a drainage tube is arranged in the sponge, and under the guidance of the drainage holes on the drainage tube, the liquid inside the sponge will flow into the drainage tube along the drainage holes, and finally be discharged into the liquid accumulation bag at the bottom of the drainage tube, thereby achieving the effect of anti-seepage and drainage, preventing the risk of wound infection caused by accumulation of liquid, and also solving the problem of frequent dressing changes.

[0022] (2) The water-absorbing material of the present invention is located above the dressing component. When the liquid seeps out too quickly and the dressing component is not drained in time, the accumulated liquid will accumulate. When the accumulated liquid reaches the drainage tube at the bottom of the water-absorbing material, it flows out through the drainage tube. At this time, the nurse can be reminded to replace the dressing component and the absorbent material, so that the accumulated liquid in the device can be visualized, which further prevents the risk of wound infection caused by the accumulation of liquid, and is beneficial to the healing of the patient's wound.

[0023] (3) A dressing ejection assembly is provided between the base and the seat cover of the present invention. When the seat cover is opened, the spring pushes the head of the ejector pin to the annular limiter, and the dressing assembly is placed. The bottom surface of the dressing of the dressing assembly fits the patient's skin, and the outer side surface of the dressing fits the inner side wall of the base. The gauze of the dressing assembly falls on the stepped top surface of the base. The seat cover is closed, and the seat cover presses the ejector pin down. The tip of the ejector pin cooperates with the sharp groove of the seat cover to fix the four sides of the gauze between the seat cover and the base, so that the wound surface will not be pressed and the patient will not feel uncomfortable. When the seat cover is opened, the top pin moves upward under the tension of the spring. A rubber ring is provided on the outer ring of the head of the top pin, and the rubber ring forms a sealing state with the inner wall of the sink groove. The upward movement of the top pin depends on the air intake of the air hole. The air intake of the air hole slowly causes the top pin to move upward, and the top of the top pin drives the dressing component to gradually rise from the gauze at the edge to the middle dressing, which facilitates the inconvenience of nurses in removing the dressing component. The slow air intake of the air hole and the gradual upward movement of the top pin also avoid the adhesive layer of the sponge from separating from the patient's skin and causing discomfort to the patient. It is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0034] Example 1

[0035] like Figure 1-8 As shown, an anti-seepage drainage device for abdominal surgery includes a base 1, the bottom of the base 1 is arranged in an arc shape, one side of the base 1 is rotatably connected to a seat cover 2, and the base 1 and the seat cover 2 are both square frame structures; a dressing component 3 is installed in the base 1, and the four sides of the dressing component 3 are fixedly installed between the base 1 and the seat cover 2; a water-absorbing material 4 is placed on the dressing component 3, and the water-absorbing material 4 is located in the seat cover 2;

[0036] The arc-shaped bottom of the base 1 is used to better fit the patient's skin and prevent the leakage of liquid exuding from the wound. The base 1 and the seat cover 2 are rectangular frames. The base 1 is used to place the dressing assembly 3, and the seat cover 2 is used to place the absorbent material 4.

[0037] A suction cup 5 is fixed to the bottom of the base 1; the first drainage tube 11 is connected to the left and right sides of the dressing component 3, and the second drainage tube 12 is connected to one side of the water-absorbing material 4, and the first drainage tube 11 and the second drainage tube 12 are both connected to the fluid collection bag 7; a plurality of dressing ejection components 8 that are connected to the seat cover 2 are arranged on both sides of the base 1.

[0038] On the basis of setting the bottom of the base 1 into an arc shape, in order to better prevent seepage, a suction cup 5 is arranged around the bottom of the base 1, so that the suction cup 5 can suck the patient's skin to achieve a sealed isolation between the inside and the outside of the base 1; the dressing component 3 and the water-absorbing material 4 are both used to absorb the liquid flowing out of the wound, the first drainage tube 11 is used to drain the liquid on both sides of the dressing component 3, and the second drainage tube 12 is used to drain the liquid at the bottom of the water-absorbing material 4. The water-absorbing material 4 can also be a sponge or a water-absorbing resin material.

[0039] In this embodiment, the dressing assembly 3 includes a gauze 31, which is in sheet form, and a dressing 33 is fixedly attached to one side of the gauze 31. The side of the dressing 33 away from the gauze 31 is in an arc shape with a middle high and an outer low shape, and is consistent with the curvature of the bottom of the base 1; the outer wall of the dressing 33 is attached to the inner wall of the base 1, and the surrounding of the gauze 31 is located between the base 1 and the seat cover 2;

[0040] The dressing 33 includes a medicine 331 disposed in the middle and sponges 332 disposed on both sides of the medicine 331 . An adhesive layer is disposed on a surface of the sponge 332 away from the gauze 31 .

[0041] When in use, the dressing 33 is placed in the base 1, and the outer wall of the dressing 33 fits the inner wall of the base 1, and the dressing 33 fits the patient's skin. Because the bottom surface of the dressing 33 is in an arc shape with a high middle and low sides, after the liquid is absorbed, the liquid absorbed in the medicine 331 will flow into the sponges 332 on both sides, thereby achieving the effect of keeping the wound area corresponding to the medicine 331 moist, which is beneficial to wound healing.

[0042] The medicine 331 is beneficial for sterilizing and inhibiting bacteria at the wound and promoting wound healing. The sponge 332 is used to absorb exudate, and the adhesive layer enables the dressing to better fit the skin and protect the wound surface.

[0043] In this embodiment, a guide tube 6 is installed in the sponge 332 located on both sides of the medicine 331, and a guide tube 6 is also installed on one side of the absorbent material 4. The guide tube 6 is arranged in an L shape, and a plurality of drainage holes are arranged on the tube wall of the guide tube 6. The plurality of drainage holes are arranged on 1 / 2 to 2 / 3 of the upper part of the cross-section of the guide tube 6.

[0044] The guide tube 6 is used to guide the liquid absorbed and accumulated in the sponge 332 and the water-absorbing material 4, thereby achieving the function of drainage.

[0045] In this embodiment, the guide tube 6 located in the sponge 332 is horizontally arranged at the thicker end of the sponge 332, and the water outlet of the guide tube 6 is located on the side away from the medicinal material 331. The water inlet end of the first drainage tube 11 penetrates the side wall of the base 1 and is connected with the water outlet of the guide tube 6.

[0046] When liquid seeps out, the medicine 331 absorbs the exudate. Due to the arc-shaped setting of the dressing 33, the accumulated liquid of the medicine 331 will flow to the sponges 332 on both sides. The sponge 332 is installed with a guide tube 6. The drainage holes set on the guide tube 6 open multiple liquid inlet channels for the liquid in the sponge 332 to enter the guide tube 6. Under the setting of the guide holes, the liquid flows to the bottom of the guide tube 6 and flows to the liquid accumulation bag 7 through the first drainage tube 11 connected thereto, achieving the drainage function. It should be noted that through holes are provided on both sides of the base 1. The through holes are set at the water outlet of the guide tube 6 to facilitate the connection between the first drainage tube 11 and the guide tube 6. The sponges 332 on both sides of the medicine 331 are provided with guide tubes 6. The guide tubes 6 on both sides are drained through the connected first drainage tubes 11.

[0047] In this embodiment, the guide tube 6 located in the water-absorbing material 4 is horizontally arranged at the lower end of the water-absorbing material 4, the water outlet of the guide tube 6 is located on one side of the water-absorbing material 4, and the water inlet of the second drainage tube 12 passes through the side wall of the seat cover 2 and is connected with the water outlet of the guide tube 6.

[0048] When the liquid flows out too fast, the dressing assembly 3 cannot meet the requirement of fast liquid drainage, and the liquid accumulates on the base. When the liquid accumulates to the bottom of the water-absorbing material 4, the liquid is drained from the drainage tube 6 provided on one side of the water-absorbing material 4. At this time, liquid flows out of the second drainage tube 12, which can remind the nurse to replace the dressing assembly 3 and the water-absorbing material 4. It should be noted that a through hole is provided on one side of the seat cover 2, and the through hole is provided at the water outlet of the drainage tube 6 to facilitate the connection between the second drainage tube 12 and the drainage tube 6.

[0049] In this embodiment, the dressing ejection assembly 8 includes a plurality of sink grooves 81 arranged at the top of both sides of the base 1, and a pointed groove 85 arranged at the bottom of the seat cover 2, and the plurality of sink grooves 81 are evenly distributed along the two side walls; an annular limiter 82 is screwed and fixed to the inner side of the top of the sink groove 81, a spring 83 is installed at the bottom of the sink groove 81, and a top nail 84 is also installed in the sink groove 81 above the spring 83, the head of the top nail 84 abuts against the spring 83, a rubber ring 86 is fixed to the outer edge of the head of the top nail 84, the rubber ring 86 is slidably connected in the sink groove 81 along the head of the top nail 84, and the tail of the top nail 84 is slidably connected in the annular limiter 82; a tip is provided at the tail of the top nail 84, and the pointed groove 85 is adapted to the tip; an air hole 87 connected to the bottom of the sink groove 81 is also opened on the side wall of the base 1.

[0050] The dressing ejection assembly 8 is arranged between the base 1 and the seat cover 2. When the base 1 and the seat cover 2 are covered, the four sides of the gauze 31 are located in the gap between the base 1 and the seat cover 2. The sharp groove 85 is adapted to the tip of the tail of the top pin 84 so that the gauze 31 is pierced by the tip and fixed on the tip. When the seat cover 2 is opened, the top pin 84 will slide upward due to the tension of the spring 83. Because a rubber ring 86 is fixed to the outer ring of the head of the top pin 84, the rubber ring 86 abuts against the inner wall of the sink groove 81 to form a seal. Therefore, the upward sliding of the spring 83 also needs to be controlled by the air intake speed of the air hole 87. The air hole 87 plays a role of slowly rising the upward movement of the top pin 84. Therefore, the rise of the top pin 84 can facilitate the removal of the dressing assembly by medical staff. Furthermore, the slow rise of the top pin 84 can reduce the discomfort of the sponge sticking to the skin during removal, will not cause pain, and improve the patient's comfort.

[0051] In this embodiment, a retractable belt 10 is connected between the two side walls of the base 1 .

[0052] The retractable belt 10 is used to install the device on the patient's abdomen, and can be adjusted according to the size of the abdomen of different patients. Specifically, it can be adjusted by buckle installation.

[0053] In this embodiment, the first drainage tube 11, the second drainage tube 12 and the fluid collection bag 7 are all made of transparent plastic material, specifically PVC plastic, PE plastic, ABS plastic; the first drainage tube 11, the second drainage tube 12 and the fluid collection bag 7 are made transparent to facilitate patients or medical staff to check the specific situation of the exudate.

[0054] In this embodiment, the suction cup 5 is fixed around the bottom wall of the base 1, and an arc-shaped groove is provided on the bottom wall of the suction cup 5.

[0055] The suction cup 5 is made of a long strip of soft rubber material, specifically nitrile rubber, silicone or soft PVC. The suction cup 5 is fixed around the bottom of the base 1 and is arranged in an arc shape on the bottom wall, so that it can be better adsorbed on the patient's skin surface to achieve an anti-seepage effect.

[0056] In this embodiment, a latch 13 is provided between the other side of the base 1 and the seat cover 2 where they are rotatably connected.

[0057] The latch makes the base 1 and the seat cover 2 cover more tightly. In order to cover tightly, a foam sealing strip can also be installed on the base 1 or the seat cover 2 at the cover.

[0058] The working principle of the anti-seepage drainage device for abdominal surgery of the present invention is as follows:

[0059] When in use, the retractable belt 10 is put on the patient's abdomen, the abdominal wound is placed in the middle of the base 1, the suction cup at the bottom of the base 1 is sucked around the patient's abdominal wound, and then the retractable belt 10 is adjusted to an appropriate degree of tightness, the seat cover 2 is opened, the dressing assembly 3 is placed in the base 1, the outer wall of the dressing 33 is in contact with the inner wall of the base 1, the four sides of the gauze 31 are placed around the top of the base 1, the seat cover 2 is covered, and the seat cover 2 is tightened by the pin 13, the tip of the top pin 84 on the base 1 and the sharp groove 85 on the seat cover 2 are engaged to fix the gauze 31, and the dressing assembly 3 is fixed; the absorbent material is placed above the dressing assembly 3, the outer wall of the absorbent material 4 is in contact with the inner wall of the seat cover 2, the first drainage tube 11 passes through the side wall of the base 1 and is connected to the drainage tube 6 in the sponge 332 of the dressing 33, and the second drainage tube 12 passes through the side wall of the seat cover 2 and is connected to the drainage tube 6 at the bottom of the absorbent material 4.

[0060] When liquid exudes from the patient's wound, the medicine 331 absorbs the liquid. Since the bottom of the dressing 33 is arranged in an arc shape, the liquid absorbed by the medicine 331 flows into the low-positioned sponges 332 on both sides and is absorbed by the sponges. The liquid in the sponge 332 is guided through the provided guide tube 6 to be discharged into the fluid collection bag 7. In order to better guide the liquid, a plurality of guide holes are evenly distributed on the upper 1 / 2 to 2 / 3 of the cross-section of the guide tube 6. The liquid in the sponge 332 flows into the bottom of the cross-section of the guide tube 6 through the guide holes and is discharged into the fluid collection bag 7 through the first drainage tube 11. Drainage can be achieved without worrying about leakage.

[0061] When the patient's liquid exudes too quickly, the drainage speed of the dressing assembly 3 is not enough to quickly drain the liquid, and the liquid accumulates on the dressing 33 of the dressing assembly 3. When the liquid accumulates to the bottom of the water-absorbing material 4, the guide tube 6 provided on one side of the bottom of the water-absorbing material 4 will infiltrate the liquid and discharge it through the second drainage tube 12. At this time, the medical staff can replace the dressing assembly 3 and the water-absorbing material 4 according to the liquid discharged from the second drainage tube 12.

[0062] When replacing, first disconnect the first drainage tube 11 and the second drainage tube 12 from the guide tube 6, take out the absorbent material 4, open the seat cover 2, when the seat cover 2 is opened, the pointed groove 85 leaves the tip of the top pin 84, and the spring 83 of the dressing ejection assembly 8 pushes the top pin 84 upward, and the combination of the rubber ring 86 and the air hole 87 slows down the upward sliding speed of the top pin 84, slowly rises, and drives the gauze 31 on the tip of the top pin 84 to rise. After the rise is completed, it is convenient for medical staff to remove the dressing assembly 3. Furthermore, the slow rise of the top pin 84 reduces the discomfort of removing the adhesive layer at the bottom of the sponge 332 from the patient's skin.

[0063] Although the present invention has been disclosed as above by embodiments, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
