Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an integrated dressing-changing device for removing closed drainage tubes. Background Art

[0002] In clinical medicine, the removal of closed drainage tubes is a common operation in departments such as thoracic surgery and respiratory medicine, and is widely used in various situations such as pneumothorax, pleural effusion, and postoperative drainage of the chest. At present, the tube removal operation mainly relies on traditional dressing packs, which contain basic tools such as scissors, sterile gauze, sand balls, and dressings. During the tube removal process, medical staff usually require the patient to take a deep breath and hold it (Valsalva maneuver). The purpose of this maneuver is to reduce the negative pressure in the chest cavity, prevent gas or liquid from flowing back, and thus reduce the risk of pneumothorax recurrence or infection. However, the existing tube removal operation methods have many problems and need to be improved urgently.

[0003] First of all, the cooperation of patients during the tube removal process is relatively low. Some patients, due to pain, anxiety, age factors (such as children or the elderly), or cognitive impairment, are unable to effectively complete the deep inhalation and breath-holding actions. In this case, the thoracic pressure will change suddenly during tube removal, thus increasing the risk of complications such as pneumothorax recurrence and subcutaneous emphysema. Secondly, the existing tube removal operation highly depends on the experience of medical staff. Medical staff need to manually guide the patient to control breathing. This process not only takes a long time, but also in emergency situations, such as when the patient suddenly coughs, it is difficult for medical staff to accurately control the operation rhythm, resulting in a reduced success rate of tube removal.

[0004] In addition, the closing effect of traditional dressings is also not satisfactory. The existing dressings can only cover the wound and lack an active closing mechanism. After tube removal, the wound may form tiny gaps due to poor tissue elastic retraction, which undoubtedly increases the risk of infection or exudation. Although current technologies have tried to solve these problems by improving the viscosity of dressings (such as using hydrocolloid dressings) or optimizing the operation process (such as using staged tube removal), these improvement measures do not fundamentally solve the core contradiction, that is, the contradiction between the patient's breathing cooperation and the dynamic closing requirement of the wound. Summary of the Invention

[0005] The present invention aims to provide an integrated dressing-changing device for removing closed drainage tubes to synchronously assist patients in respiratory management during the tube removal process, provide wound closing support, reduce operation risks, and improve medical quality.

[0006] To achieve the above object, the present invention provides the following technical solution: An integrated dressing-changing device for removing closed drainage tubes, including a dressing pack, wherein the dressing pack is provided with a sterile scissor, a sterile plastic forceps, a gauze, a sand ball, an oral-nasal closed-type respiratory assistance mask, an elastic tension adhesive dressing, and a medical garbage bag.

[0007] Preferably, the mouth-nose closed breathing assistance mask includes a mask body bulging in the middle. A sealing ring is fixedly connected around the mask body. A plurality of arc-shaped holes are opened at the top of the mask body. An airbag one is fixedly connected in the middle of the top of the mask body. An airbag two is arranged around the airbag one. The airbag two is fixedly connected to the mask body. A trachea is fixedly connected to the front end of the airbag one. The free end of the trachea communicates from the front end of the top of the mask body to the inside of the mask body. The free end of the trachea is fixedly connected with a symmetrically arranged pressing device. The pressing device includes a connecting pipe fixedly connected to the trachea. A pair of symmetrically arranged pressing channels are opened on the inner side wall of the mask body. A through hole is opened on the side wall of the pressing channel near the mask body. The free end of the connecting pipe passes through the through hole and is fixedly connected with a pressing block cooperating with the pressing channel. An airbag three is fixedly connected to the top end of the inner wall of the mask body. A shielding plate is fixedly connected to the bottom end of the airbag three. A plurality of gas channels communicating the airbag two and the airbag three are opened at the top of the mask body. A pair of symmetrically arranged spring pieces are fixedly connected to the middle of the inner wall of the mask body.

[0008] Preferably, the center of the elastic tension adhesive dressing is a sterile dressing. An elastic cloth is fixedly connected to the top of the sterile dressing. Non-woven fabrics are fixedly connected to the surrounding elastic cloth. An adhesive layer is arranged at the bottom end of the non-woven fabric.

[0009] Preferably, the elastic cloth is in a contracted state under normal conditions and can provide a lateral tension of 5-10 N after being stretched.

[0010] Preferably, the mask body is made of a hard material, and the sealing ring is made of a medical-grade silicone material.

[0011] Preferably, the airbag one, the airbag two and the airbag three are all flexible elastic airbags, and can generate gas flow through pressing, so as to drive the shielding plate and the pressing block to move to realize the forced closure of the patient's mouth and nose.

[0012] Preferably, the sterile dressing part of the elastic tension adhesive dressing is made of a hydrophilic material, can absorb wound exudate, keep the wound dry and promote wound healing.

[0013] Preferably, the adhesive layer of the elastic tension adhesive dressing is made of a medical pressure-sensitive adhesive, has good adhesiveness and biocompatibility, and can be firmly pasted on the patient's skin.

[0014] The principle and beneficial effects of this technical solution:

[0015] The principle and beneficial effects of this technical solution are mainly reflected in the following aspects:

[0016] The closed - drainage tube removal integrated dressing - changing device of the present invention realizes effective management of the patient's breathing through the mouth - nose closed - type breathing assistance mask. During the tube removal process, patients often need to take a deep breath and hold their breath to reduce the negative pressure in the chest cavity, prevent gas or liquid reflux, and thus reduce the risk of pneumothorax recurrence or infection. However, traditional tube removal operations highly rely on the patient's subjective cooperation and the experience guidance of medical staff, which have many problems in actual operation. Some patients may be unable to effectively complete the deep - inhalation and breath - holding actions due to pain, anxiety, age factors, or cognitive impairment, etc., resulting in a sudden change in chest cavity pressure during tube removal, increasing the risk of complications such as pneumothorax recurrence and subcutaneous emphysema. The mouth - nose closed - type breathing assistance mask of the present invention can force the patient into a breath - holding state through its unique structural design without relying on the patient's subjective cooperation. After wearing the mask, the patient inhales naturally to the total lung capacity, and the medical staff presses airbag one and airbag two to move the baffle and the pressing block, thus forcing the patient to hold their breath. This design not only improves the success rate of the operation. Especially for populations with low cooperation degrees such as children and elderly patients, the success rate of the operation has increased from 93% to 98%, but also avoids the occurrence of situations such as pneumothorax caused by improper patient breathing cooperation.

[0017] The elastic tension adhesive dressing of the present invention plays an important role in wound closure. Traditional dressings can only cover the wound and lack an active closure mechanism, unable to effectively deal with the tiny gaps that may form due to poor tissue elastic retraction after tube removal, thus increasing the risk of infection or exudation. The center of the elastic tension adhesive dressing of the present invention is a sterile dressing, the top is fixedly connected with an elastic cloth, the periphery is fixedly connected with a non - woven fabric, and an adhesive layer is arranged at the bottom of the non - woven fabric. When in use, the non - woven fabric part is pulled to unfold the elastic cloth, and the sterile dressing part covers the wound surface. After being pasted on the patient's skin, the periphery will apply force to the wound, promoting the apposition of the wound edges. This design not only improves the apposition degree of the wound edges, reduces the incidence of exudation, but also extends the dressing - changing frequency from once every 48 hours to once every 72 hours, effectively reducing the patient's pain and medical costs.

[0018] The integrated dressing - changing device of the present invention also has the advantages of standardized operation, improved efficiency, and significant cost - effectiveness. The integrated dressing - changing kit contains various tools and materials required for tube removal operations, reducing the preoperative preparation time from an average of 5 minutes to 1 minute, especially suitable for emergency or resource - limited scenarios.

Detailed implementation manners

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0026] Embodiment 1:

[0027] The present invention provides an integrated dressing change device for closed drainage tube removal, including a dressing change kit, which is equipped with a sterile scissors, two sterile plastic forceps, three gauzes, five cotton balls, a mouth and nose closed type respiratory assistance mask, two elastic tension adhesive dressings of different sizes, and a medical garbage bag. The combination of these tools and materials provides comprehensive and convenient support for closed drainage tube removal and subsequent dressing change operations.

[0028] (1) Mouth and nose closed type respiratory assistance mask

[0029] As Figures 1 - 3 shown, the mouth and nose closed type respiratory assistance mask includes a cover body 1 with a bulged middle part. A sealing ring 2 is fixedly connected around the cover body 1. The sealing ring 2 is made of medical grade silicone material, which is soft and has good sealing performance, and can be closely attached to the patient's face to ensure that the mask will not leak air during use. A number of arc-shaped holes 3 are opened at the top of the cover body 1. The design of these holes allows the patient to inhale naturally to the total lung capacity when wearing the mask, ensuring the smoothness of breathing.

[0030] At the middle of the top end of the cover body 1, an airbag one 4 is fixedly connected, and airbag two 5 is arranged around it. The airbag two 5 is fixedly connected with the cover body 1. The front end of the airbag one 4 is fixedly connected with a trachea 6. The free end of the trachea 6 communicates from the front end of the top end of the cover body 1 to the inside of the cover body 1 and is fixedly connected with symmetrically arranged pressing devices. The pressing device consists of a connecting pipe 7 and a pressing block 9. The connecting pipe 7 is fixedly connected with the trachea 6. A pair of symmetrically arranged pressing channels 8 are opened on the inner side wall of the cover body 1. Through holes are opened on the side wall of the pressing channel 8 close to the cover body 1. The free end of the connecting pipe 7 passes through the through hole and is fixedly connected with the pressing block 9. The pressing block 9 fits tightly with the pressing channel 8. When in use, the two symmetric pressing blocks 9 are pushed into the pressing channels 8. At this time, the airbag one 4 bulges and the connecting pipe 7 is in a wrinkled state, so that the patient's nose wings are at the outlets of the two pressing channels 8. When the airbag one 4 is pressed, the gas in it will make the wrinkled connecting pipe 7 straighten through the trachea 6, that is, the pressing block 9 moves in the pressing channel 8 to press the patient's nose wings, ensuring that the nose part will not breathe.

[0031] An airbag three 10 is fixedly connected to the top end inner wall of the cover body 1, and a baffle 13 is fixedly connected to the bottom end of the airbag three 10. A plurality of gas channels 11 communicating the airbag two 5 and the airbag three 10 are also opened at the top end of the cover body 1. These channels enable the gas between the airbags to flow mutually. A pair of symmetrically arranged spring pieces 12 are fixedly connected to the middle part of the inner wall of the cover body 1 to play a supporting role in the natural state. When in use, the baffle 13 is pushed to the top end of the face mask. At this time, the airbag three 10 contracts and the airbag two 5 bulges, so that the patient's mouth is under the baffle 13. When the airbag two 5 is pressed, the gas in it will make the contracted airbag three 10 bulge through the gas channel 11, that is, the baffle 13 breaks through the restraint of the spring piece 12 and moves downward to block the patient's mouth, ensuring that the patient will not breathe through the mouth.

[0032] The cover body 1 of this face mask is made of a hard material, which can maintain a stable shape and is not easy to deform, ensuring that it can play a role accurately during the operation. The medical-grade silicone material of the sealing ring 2 ensures the safety and comfort of contacting with the patient's face. The face mask is designed in two sizes. One size fits the facial contours of adults and teenagers, and the other children's version size is reduced by 30% to meet the needs of patients of different age groups.

[0033] (2) Elastic tension adhesive dressing

[0034] As Figures 4 - 5 shown, the elastic tension adhesive dressing is another important part of the present invention. Its structural design is unique. The center is a sterile dressing 14, and an elastic cloth 15 is fixedly connected to the top end of the sterile dressing 14. Under normal conditions, the elastic cloth 15 is in a contracted state, but when stretched, it can provide a lateral tension of 5 - 10 N.

[0035] The four sides of the elastic cloth 15 are fixedly connected with a non-woven fabric 16. The material of the non-woven fabric 16 is not easily deformed due to pulling and has good stability. A glue layer 17 is provided at the bottom end of the non-woven fabric 16, and the glue layer 17 is used to paste with the skin to ensure that the dressing can be firmly fixed around the wound. During use, the elastic cloth 15 is unfolded by pulling a part of the non-woven fabric 16, and a part of the sterile dressing 14 is covered on the wound surface, and then pasted on the patient's skin. After pasting, the elastic cloth 15 around will apply a force to the wound, promoting the alignment of the wound edges, thereby improving the wound healing effect.

[0036] The specific implementation process is as follows:

[0037] (1) Mouth-nose closed type respiratory assist mask

[0038] The use of the mask avoids problems such as improper control of breathing by the patient himself and improper position when medical staff help the patient quickly cover the mouth and nose, which may hurt the nasal bone. When the patient wears the mask, through the arc-shaped hole 3 above, it can ensure that the patient inhales naturally to the total lung capacity. At this time, the medical staff presses down on the airbag one 4 and the airbag two 5, and the gas at the squeezed position in the airbag will spread to other positions in the airbag. This process will drive the covering plate and the two pressing blocks 9 to move. Since when the patient knows that he needs to hold his breath and the breath-holding state only needs to be maintained for 5-10 seconds, a relatively small force can completely cover the mouth and close the nasal wings, thus ensuring that the patient is forced into the breath-holding state without relying on the patient's subjective cooperation.

[0039] Before extubation, keep the baffle 13 at the top of the mask and the two pressing blocks 9 open. The medical staff covers the mask above the patient's mouth and nose. When the patient inhales to the end of the total lung capacity, quickly press the extrusion block and perform the extubation operation synchronously. This design enables precise control of the patient's breathing during the extubation process, reducing the risks such as pneumothorax caused by poor breathing coordination, especially suitable for populations with low cooperation such as children and elderly patients. In this way, the operation success rate is increased from the traditional 93% to 98%, significantly improving the safety and reliability of medical operations.

[0040] (2) Elastic tension adhesive dressing

[0041] The structural design of the elastic tension adhesive dressing plays an important role in wound closure. During use, the medical staff first pulls a part of the non-woven fabric 16 to unfold the elastic cloth 15, and covers a part of the sterile dressing 14 on the wound surface. Then, the dressing is pasted on the patient's skin. Since the elastic cloth 15 can provide a lateral tension of 5-10 N after being stretched, a force will be applied to the wound around after pasting, promoting the alignment of the wound edges. This active closure mechanism has significant advantages compared with traditional dressings that can only cover the wound and lack the active closure function.

[0042] With this design, the degree of apposition of the wound edges can be increased by 40%, and the incidence of exudate can be reduced to 3%, while the incidence of exudate of traditional dressings is 12%. In addition, since the elastic tension adhesive dressing can better maintain the wound in a closed state, the dressing change frequency can also be extended from once every 48 hours to once every 72 hours. This not only reduces the workload of medical staff, but also reduces the pain of patients and medical costs, and improves the utilization efficiency of medical resources.

[0043] The above are only embodiments of the present invention, and specific technical solutions or common knowledge such as characteristics well known in the art are not described in detail herein. For those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
