Description

Technical Field

[0001] The invention relates to the technical field of medical care, and in particular to a wound water extraction and overflow prevention device and a use method thereof. Background Art

[0002] In hospital clinical practice, patients with cirrhosis often suffer from ascites. Timely suction and discharge of ascites is an effective treatment method that can prevent the disease from further deteriorating.

[0003] The current method of ascites aspiration is to aspirate ascites with an ascites aspirator or syringe, insert a puncture needle into the abdominal cavity, and then aspirate with the aspirator or syringe. In order to avoid the pain of repeated punctures, the abdomen is clinically left with a puncture hole to facilitate the next aspiration.

[0004] In the prior art, for example, the Chinese invention patent application publication number: CN 108096686 A discloses a thoracoabdominal drainage tube, including a guide tube, the two ends of the guide tube are respectively a drainage input end for inserting into the thoracoabdominal cavity and a drainage output end for staying outside the thoracoabdominal cavity, the drainage input end is provided with a plurality of drainage holes, a flexible water bag sleeve that can be filled with water is sleeved on the outside of the guide tube, the flexible water bag sleeve is connected to a water injection assembly, the flexible water bag sleeve has a wrapping part that tightly wraps the guide tube when the flexible water bag sleeve is not filled with water, and expands to form an expanded inner cavity after the flexible water bag sleeve is filled with water, the drainage input end and all the drainage holes are located in the expanded inner cavity, and the wrapping part has a plurality of filtering holes that connect the expanded inner cavity and the external environment. The thoracoabdominal drainage tube has the advantages of simple structure, low cost, convenient operation, and complete drainage without adjustment.

[0005] In the above patented technical solution, firstly, the stopper is expanded by injecting water into the flexible water bag sleeve, and the expanded stopper is used to abut against the inner side of the chest wall and the abdominal wall, so as to prevent the guide tube from withdrawing, and ensure the reliable drainage. However, the disadvantage is that once the guide tube is pulled by external force, the expanded stopper will inevitably transmit the pulling force to the inner side of the chest wall and the abdominal wall, resulting in compression and damage to the inner side of the chest wall and the abdominal wall in the wound area, causing great pain to the patient. In addition, in the above patent technical solution, the annular water bag and the stopper are arranged to clamp and fix the chest wall or abdominal wall, which plays a role in fixing the guide tube. However, since the annular water bag and the stopper clamp the chest wall or abdominal wall where the wound is located, the patient is not comfortable when using it, the fixing method is not convenient, the fixing effect is not good, and it will also cause pain to the patient, which is not conducive to the implementation of accurate clamping operation; Finally, in the above-mentioned patented technical solution, the flexible water bag sleeve between the stop portion and the annular water bag is expanded by filling it with water, which can only partially block the puncture channel of the chest wall or abdominal wall, but cannot completely block the overflow of body fluids. This is also a common sense issue. However, not much innovative design has been made in preventing overflow, so that when tissue fluid or pus overflows, the patient cannot be properly treated, which contaminates or stains the skin around the affected area.

[0006] In summary, there is an urgent need to propose a wound water extraction and overflow prevention device and a method of using the device to overcome the above problems. Summary of the invention

Even if the wound overflow prevention barrier fails, the annular absorption structure can well achieve the absorption and barrier effect of the tissue fluid or pus overflowing from the wound, greatly reducing the contaminated area of ​​the patient's skin. In addition, it can resist strong pulling from the outside world on the suction tube.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Example 1

[0025] like Figures 1 to 12 As shown, in one embodiment of the present application, a wound water extraction and overflow prevention device is provided, comprising: The water extraction tube 1 has one end which passes through the adhesive limiting structure 2, the annular absorption structure 3 and the tube limiting structure 6 in sequence and then is inserted into the patient's wound, and the other end is exposed outside the patient's wound and is connected to the pump body (not shown in the figure) to extract and dredge the tissue fluid in the wound; The limiting structure 2 is attached to the water extraction pipe 1 and bonded to the wound of the patient to locate and cover the periphery of the wound of the patient; The annular absorption structure 3 is arranged in the adhesive limiting structure 2, the outer surface of the adhesive limiting structure 2 is exposed, and abuts against the outer peripheral surface of the wound to absorb and block the tissue fluid overflowing from the wound; The anti-warping structure 4 is arranged at the outer edge of the sticking limiting structure 2, and can be received on the sticking limiting structure 2 to be flexibly bonded to the periphery of the patient's wound; The squeezing type overflow prevention structure 5 is inserted into the sticking limiting structure 2 and arranged on the outer peripheral surface of the water extraction pipe 1 to form a squeezing posture with the inner surface of the wound to prevent the tissue fluid in the wound from overflowing; The pipe body limiting structure 6 is clamped with the water pumping pipe 1 and connected with the adhesive limiting structure 2, so as to perform bending limiting or clamping limiting on the water pumping pipe 1; On one hand, the present embodiment is provided with an adhesive limiting structure and an anti-warping structure, which is clamped with the water extraction pipe by the adhesive limiting structure, and the adhesive limiting structure is bonded to the patient's wound, so that the wound water extraction and overflow prevention device can be bonded to the patient's affected part, avoiding the problem of displacement of the water extraction pipe and the wound water extraction and overflow prevention device, and ensuring the reliability of drainage. In addition, through the anti-warping structure design of the outer edge of the adhesive limiting structure, the anti-warping structure is flexibly bonded to the periphery of the affected part, so that the adhesive limiting structure can be firmly bonded to the patient's wound, further ensuring the reliable water extraction and drainage at the wound, reducing the pain and discomfort of the patient during use, and replacing the traditional technical solution of preventing the guide tube from withdrawing or deviating greatly by setting an annular water bag and a stopper to cooperate with the chest wall or abdominal wall to clamp and fix; Secondly, an extrusion-type overflow prevention structure and an annular absorption structure are provided. The extrusion-type overflow prevention structure is inserted into the pasting limiting structure and is provided on the outer peripheral surface of the water extraction pipe. It can form an extrusion posture with the inner surface of the wound, and can prevent the tissue fluid in the wound from overflowing. Even in the case of failure in preventing the wound from overflowing, the annular absorption structure of the present application can further absorb and block the tissue fluid or pus. The annular absorption structure is provided in the pasting limiting structure, and the outer surface of the pasting limiting structure is exposed so that it abuts against the outer peripheral surface of the wound. The annular absorption structure can well achieve the absorption and secondary blocking effect of the tissue fluid or pus overflowing from the wound, that is, through the design of the double overflow prevention structure, the overflow prevention effect is better. When the tissue fluid or pus in the patient's wound overflows, it can be properly handled, which greatly reduces the patient's skin contamination area and slows down the spread of contamination. On the other hand, a tube body limiting structure is provided, which is clamped with the water pumping pipe and connected to the adhesive limiting structure. The tube body limiting structure can realize bending limiting or clamping limiting of the water pumping pipe. The benefits of bending limiting or clamping limiting the water pumping pipe are two: on the one hand, it can resist the strong pulling of the water pumping pipe by the outside world, so that the withdrawal amplitude of the water pumping pipe can be reduced to a certain extent, avoiding the transmission of a large pulling force to the inside of the wound, resulting in compression and damage to the inner side of the chest wall and abdominal wall in the wound area, causing great pain to the patient; on the other hand, it can better facilitate the clinical organization and storage of wire harnesses and tubes, and facilitate efficient clinical management and monitoring care.

[0026] In addition, the water extraction pipe, adhesive limiting structure, annular absorption structure, anti-warping structure, extrusion-type overflow prevention structure, and tube body limiting structure of the present embodiment only contact the external surface of the wound and the longitudinal inner surface of the wound, and there is no contact or clamping with the inner sides of the chest wall and abdominal wall in the wound area. This greatly reduces the medical risks when performing overflow prevention treatment during wound drainage, greatly reduces the pain to the patient and improves the patient's medical experience, and the overall replacement of the wound drainage and overflow prevention device is more convenient and efficient.

Moreover, when the air suction tube is inserted into the wound, since the airbag has an inclined slope at the end away from the adhesive limiting structure, the air suction tube has a guiding effect during the insertion process and will not cause pain to the patient's wound, which is more conducive to the insertion of the water suction tube into the wound.

[0028] like Figure 1 , Figures 5 to 7 As shown, in the above embodiment, the pasting limiting structure 2 comprises a supporting layer 21, a cold gel layer 22 connected to a side of the supporting layer 21 away from the tube body limiting structure 6, and a release layer 23 connected to a side of the cold gel layer 22 away from the supporting layer 21, and the cold gel layer 22 is provided with a half-cut annular notch 24, and the half-cut annular notch 24 is used to accommodate the annular absorption structure 3; In this embodiment, the support layer makes the adhesive limiting structure as a whole not easy to deform, the cold gel layer makes the adhesive limiting structure more breathable, and improves the comfort of the wound, and the release layer can improve the adhesion between the adhesive limiting structure and the wound.
