Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a wound protective dressing used after tracheotomy and extraction surgery. Background Art

[0002] Tracheotomy is one of the commonly used emergency treatment methods in the clinical treatment of critically ill patients. Tracheotomy is a common treatment method to relieve dyspnea caused by laryngeal dyspnea, respiratory dysfunction or retention of lower respiratory tract secretions. After the operation, the patient needs to insert a tracheostomy tube for a long time. Sinus tracts will form at the tracheostomy wound, which takes time to heal after extubation. In order to promote the closure of the sinus tract, the patient's airway can be closed as soon as possible to avoid air leakage.

[0003] The tracheotomy wound needs to be closed and fixed clinically. Currently, there is no professional wound protection dressing for post-tracheotomy removal in clinical practice, that is, there is no professional wound protection dressing after tracheotomy removal, which is not conducive to the healing of the patient's tracheotomy wound.

[0004] However, nurses trim the tape and add gauze to protect the wound by themselves. The wound cannot be closed effectively and is prone to air leakage and sputum leakage. For example, there is no unified wound protection standard when caring for patients after tracheotomy and extubation. For young nurses, it may cause nursing difficulties and easily lead to medical disputes. After conventional endotracheal intubation and extubation, nurses often cut a long strip of tape by themselves, which is not beautiful. If observation is needed after applying it, it is necessary to prepare new materials for dressing change, which reduces work efficiency. There is no professional wound protection dressing after intubation and extubation, and there is no absorbent material, which is not conducive to the homogeneous management of wound dressings.

[0005] Based on the above reasons, there is an urgent clinical need to design a tracheotomy wound closure dressing that can solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a new technical solution for wound protection dressing after tracheotomy and extraction surgery, which can at least solve the technical problem that the existing tracheotomy tube is difficult to fix.

[0007] The present invention provides a wound protection dressing for post-tracheotomy removal surgery, comprising: a carrier, one side of the carrier having an adhesive region and a dressing region, the adhesive region being adhered to the skin through an adhesive layer, the dressing region having a first through hole; a liquid absorbing layer, the liquid absorbing layer being a medical sterile exudate absorbing dressing, the liquid absorbing layer being located in the dressing region, the liquid absorbing layer and one side of the carrier cooperating to form a receiving space, the liquid absorbing layer having liquid absorption properties, a second through hole communicating with the receiving space being provided on a side of the liquid absorbing layer away from the carrier, the receiving space being communicated with the first through hole and the second through hole respectively, the second through hole corresponding to the position of the tracheotomy wound; A first absorbent liquid, at least a portion of which is located in the receiving space; and a second absorbent liquid, wherein the second absorbent liquid is soaked in vaseline and at least a portion of which is located in the second through hole.

[0008] Optionally, at least a portion of the adhesive layer is offset from the carrier.

[0009] Optionally, the carrier is a rectangular piece, and the number of the adhesive layers is four, and they are respectively close to four vertex positions of the carrier.

[0010] Optionally, the carrier and the adhesive layer cooperate to form an I-shaped member.

[0011] Optionally, the shape of the longitudinal section of the liquid-absorbing layer is an arc-shaped ring, and / or the shape of the cross-section of the liquid-absorbing layer is a rectangle.

[0012] Optionally, the second liquid-absorbing material is in the shape of a rectangular block.

[0013] Optionally, along the thickness direction of the carrier, the orthographic projection of the liquid absorbing layer is located inside the orthographic projection of the carrier, and the carrier exceeds the edge of the liquid absorbing layer.

[0014] Optionally, the orthographic projection of the first through hole on the carrier is located inside the orthographic projection of the first liquid absorbing material on the carrier.

[0015] Optionally, the wound protection dressing for post-tracheotomy removal surgery further includes: a movable sheet, which is detachably arranged on the other side of the carrier to open or close the first through hole.

[0016] Optionally, the first absorbent liquid is medical sterile gauze, and the second absorbent liquid is medical sterile vaseline gauze block.

[0017] The wound protection dressing for post-tracheotomy removal surgery according to the embodiment of the present application adopts a carrier, a liquid absorbent layer, a first liquid absorbent and a second liquid absorbent in combination, which can protect the wound after tracheotomy and can be fixed by an adhesive layer. It can be seen that the composite dressing of the embodiment of the present invention can seal and fix the tracheotomy wound.

[0027] The wound protection dressing 100 for post-tracheotomy removal surgery according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 4 As shown, the wound protection dressing 100 for post-tracheotomy removal surgery according to an embodiment of the present application includes: a carrier 10, a liquid absorbent layer 20, a first liquid absorbent layer 40 and a second liquid absorbent layer 30.

[0029] Specifically, one side of the carrier 10 has an adhesive region and a dressing region, the adhesive region is adhered to the skin through the adhesive layer 11, and the dressing region has a first through hole 12. The liquid absorbent layer 20 is a medical sterile exudate absorbing dressing, the liquid absorbent layer 20 is located on one side of the carrier 10 and in the dressing region, the liquid absorbent layer 20 cooperates with one side of the carrier 10 to form a receiving space 21, the liquid absorbent layer 20 has liquid absorption, and a second through hole 22 connected to the receiving space 21 is opened on the side of the liquid absorbent layer 20 away from the carrier 10, the receiving space 21 is connected to the first through hole 12 and the second through hole 22 respectively, the second through hole 22 corresponds to the position of the tracheotomy wound, at least a portion of the first absorbent body 40 is located in the receiving space 21, the second absorbent body 30 is infiltrated with vaseline, and at least a portion of the second absorbent body 30 is arranged in the second through hole 22.

[0030] In other words, the wound protection dressing 100 for post-tracheotomy removal surgery according to the embodiment of the present application is mainly composed of a carrier 10, a liquid-absorbing layer 20, a first liquid-absorbing body 40 and a second liquid-absorbing body 30, wherein the adhesive area on one side of the carrier 10 can be attached to the skin through the adhesive layer 11, for example, the inner side of the carrier 10 is attached to the front side of the neck through the adhesive layer 11. A liquid-absorbing layer 20 is also provided on one side of the carrier 10, and the liquid-absorbing layer 20 cooperates with one side of the carrier 10 to form a receiving space 21, and the liquid-absorbing layer 20 has a first through hole 12 connected to the receiving space 21, and the receiving space 21 can play a role of accommodation. In addition, the liquid-absorbing layer 20 is a medical sterile exudate absorbing dressing, and the liquid-absorbing layer 20 has a liquid-absorbing effect and can absorb liquid, such as blood exuded from a wound. Among them, the adhesive layer 11 can use a medical polyethylene elastic adhesive fixing tape.

[0031] Moreover, the liquid-absorbing layer 20 is also provided with a second through hole 22, which is connected to the receiving space 21, and the second through hole 22 is located on the side of the liquid-absorbing layer 20 away from the carrier 10. For example, the inner side of the carrier 10 faces the front side of the neck, the liquid-absorbing layer 20 is located on the inner side of the carrier 10, and protrudes from the inner side of the carrier 10, so that the liquid-absorbing layer 20 can be aligned with the wound position of the tracheotomy. In addition, at least a part of the first liquid-absorbing body 40 is installed in the receiving space 21, and at least a part of the second liquid-absorbing body 30 is located at the position of the second through hole 22. The receiving space 21 is connected to the first through hole 12 and the second through hole 22 respectively, and the first liquid-absorbing body 40 is exposed to the first through hole 12, that is, the first liquid-absorbing body 40 can be replaced and observed through the first through hole 12. The first liquid-absorbing body 40, the second liquid-absorbing body 30 and the liquid-absorbing layer 20 all have a liquid-absorbing effect, and the second liquid-absorbing body 30 is infiltrated with vaseline, which also has the effect of facilitating the realization of closed wet healing. For example, the second absorbent body 30 is a medical sterile vaseline gauze block, and the first absorbent body 40 is a medical sterile gauze.

[0032] Therefore, according to the embodiment of the present application, the wound protection dressing 100 for post-tracheotomy removal surgery adopts a combination of a carrier 10, a liquid absorbent layer 20, a first liquid absorbent 40 and a second liquid absorbent 30, which can protect the wound after tracheotomy and can be fixed by the adhesive layer 11. It can be seen that the composite dressing of the embodiment of the present invention can seal and fix the tracheotomy wound, which is convenient for use and postoperative treatment.

[0033] According to one embodiment of the present application, at least a portion of the adhesive layer 11 is staggered with the carrier 10, which can simplify the structure. For example, a portion of the adhesive layer 11 overlaps with the carrier 10, and another portion is staggered with the carrier 10. This can increase the freedom of the adhesive position and increase the distance between the adhesive layer 11 and the wound, thereby effectively preventing the adhesive layer 11 from affecting the wound. In addition, it can also expand the area on the carrier 10 where the liquid absorbent layer 20 is set, thereby improving the utilization rate of the carrier 10.

[0034] In some specific embodiments of the present application, the carrier 10 is a rectangular member, and the number of adhesive layers 11 is four, and they are respectively close to the four vertex positions of the carrier 10. For example, the carrier 10 is a cuboid and extends in the up-down direction, and adhesive layers 11 are respectively provided at the upper left corner, the upper right corner, the lower left corner, and the lower right corner of the carrier 10. In this embodiment, by providing adhesive layers 11 at multiple positions, the firmness can be improved, and by dispersed fixation, it is convenient for the patient to move slightly and reduce the patient's discomfort.

[0035] According to an embodiment of the present application, the carrier 10 and the adhesive layer 11 cooperate to form an I-shaped member, for example, the carrier 10 extends in the up-down direction, and the adhesive layers 11 at the upper left corner, the upper right corner, the lower left corner, and the lower right corner extend in the left-right direction respectively, and the adhesive layers 11 at the upper left corner and the upper right corner extend along the same horizontal line at the same time, and the adhesive layers 11 at the lower left corner and the lower right corner extend along the same horizontal line at the same time. In this embodiment, the carrier 10 and the adhesive layer 11 cooperate to form a "I"-like shape, which utilizes the structural characteristics of the human body, such as the shape of the neck, and can achieve wound protection while fixing, and can also improve the comfort of the patient.

[0036] In some specific embodiments of the present application, the shape of the longitudinal section of the absorbent layer 20 is an arc ring, and / or the shape of the cross section of the absorbent layer 20 is a rectangle. The longitudinal section of the absorbent layer 20 refers to a section along the thickness direction of the carrier 10. For example, if the thickness direction of the carrier 10 is inside and outside, the longitudinal section of the absorbent layer 20 is a section along a plane from inside to outside. The cross section of the absorbent layer 20 refers to a cross section of a plane roughly parallel to the extension direction of the carrier 10. In this embodiment, by limiting the shape of the longitudinal section of the absorbent surface to an arc ring, it is beneficial to close the wound with a dressing. By limiting the shape of the cross section of the absorbent layer 20 to a rectangle, it is beneficial to expand the coverage range and set it according to the shape of the neck.

[0037] According to an embodiment of the present application, the second liquid absorbing liquid 30 is in the shape of a rectangular block, that is, the block-shaped second liquid absorbing liquid 30 can be plugged into the first through hole 12 to facilitate applying pressure and achieving sealing.

[0038] In some specific embodiments of the present application, along the thickness direction of the carrier 10, the orthographic projection of the absorbent layer 20 is located inside the orthographic projection of the carrier 10, and the carrier 10 exceeds the edge of the absorbent layer 20, which can effectively reduce the blood exuding from the wound from quickly passing through the carrier 10 or the gap between the carrier 10 and the skin.

[0039] According to one embodiment of the present application, the orthographic projection of the first through hole 12 on the carrier 10 is located inside the orthographic projection of the first liquid absorbent material 40 on the carrier 10, which can prevent the first liquid absorbent material 40 from escaping from the first through hole 12, and part of the first liquid absorbent material 40 is located on the other side of the carrier 10, which is conducive to pressurizing and fixing the first liquid absorbent material 40.

[0040] In some specific embodiments of the present application, the wound protection dressing 100 for post-tracheotomy removal surgery further includes a movable sheet, which is detachably disposed on the other side of the carrier 10 to open or close the first through hole 12. For example, when the first liquid absorbing liquid 40 does not need to be replaced, the first through hole 12 can be closed by the movable sheet, and when the first liquid absorbing liquid 40 needs to be replaced, the first through hole 12 can be opened by the movable sheet. In addition, the movable sheet can be mounted on the carrier 10 by means of rotation or snap connection.

[0041] According to one embodiment of the present application, the first absorbent liquid 40 and the second absorbent liquid 30 are an integral part, for example, the first absorbent liquid 40 is bowl-shaped, the second absorbent liquid 30 is block-shaped, and the first absorbent liquid 40 and the second absorbent liquid 30 are gauze formed integrally. In this embodiment, by using the first absorbent liquid 40 and the second absorbent liquid 30 as an integral structure, it is beneficial to improve the replacement efficiency.

[0042] In some specific embodiments of the present application, the first absorbent liquid 40 is medical sterile gauze, and the second absorbent liquid 30 is medical sterile vaseline gauze block, which are widely available and can be made with daily gauze and vaseline, etc., which is easy to make and reduces costs.

[0043] In summary, the wound protection dressing 100 for post-tracheotomy removal surgery according to the embodiment of the present application is a combination of a carrier 10, a liquid absorbent layer 20, a first liquid absorbent layer 40 and a second liquid absorbent layer 30, which can protect the wound after tracheotomy and can be fixed by the adhesive layer 11. The composite dressing of the embodiment of the present invention can seal and fix the tracheotomy wound.
