Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a dressing change assist device for pressure injury care. Background Technology
[0002] Pressure injuries, also known as pressure sores, pressure ulcers, or bedsores, are caused by prolonged pressure on local tissues, leading to persistent ischemia, hypoxia, malnutrition, and ultimately tissue necrosis and ulceration. For patients with severe pressure injuries, dressing changes are necessary. The procedure for changing dressings for pressure injuries involves: removing the dressing, cleaning, debridement, disinfection, applying medication, and then applying an outer dressing.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a dressing change auxiliary device for pressure injury care, including an upper wall 1, a lower wall 2, a fixing ring 3, a support ring 4, and a connecting part. The edges of the upper wall 1 and the lower wall 2 are fixedly connected opposite each other, forming a receiving cavity 5. A first through hole 6 is formed in the middle of the upper wall 1, and a second through hole 7 is formed in the middle of the lower wall 2. The fixing ring 3 is located in the second through hole 7, and the edge of the fixing ring 3 is fixedly connected to the edge of the second through hole 7. Specifically, the edge of the fixing ring 3 and the edge of the second through hole 7 can be fixedly connected by adhesive bonding to prevent cleaning fluid from passing between the edge of the fixing ring 3 and the edge of the second through hole 7. The lower side of the fixing ring 3 has an adhesive layer. The support ring 4 is located in the first through hole 6, and the edge of the support ring 4 is fixedly connected to the edge of the first through hole 6. The connecting part connects the support ring 4 and the fixing ring 3.
[0030] When using the pressure injury care dressing change assist device of this invention to assist in cleaning a patient's pressure injury wound, the patient should lie on their side with their back facing diagonally upwards. The fixing ring 3 is then adhered to the skin of the patient's back using an adhesive layer, surrounding the wound. The cleaning solution can then flow downwards through the annular holes of the support ring 4 to the wound site for cleaning. During wound cleaning, the cleaning solution can flow through the gap between the support ring 4 and the fixing ring 3 into the portion of the receiving cavity 5 located below the wound. When using the pressure injury care dressing change assist device of this invention to clean the wound, the portion of the receiving cavity 5 located below the wound can contain the cleaning solution flowing down after cleaning, reducing the possibility of the cleaning solution flowing down onto the bed sheet and reducing the possibility of the bed sheet becoming wet and contaminated.
[0031] In this embodiment, both the upper wall 1 and the lower wall 2 are made of plastic film. It is understood that the upper wall 1 and the lower wall 2 are not limited to being made of plastic film; for example, in some embodiments, both the upper wall 1 and the lower wall 2 may also be made of rubber film.
[0032] Since both the upper wall 1 and the lower wall 2 are made of plastic film, i.e., both the upper wall 1 and the lower wall 2 are flexible, the space occupied can be reduced when storing and placing the pressure injury care dressing change auxiliary device of this utility model before using it.
[0033] In this embodiment, the fixing ring 3 is made of rubber material. This gives the fixing ring 3 a certain elastic deformation capacity, allowing it to adhere more tightly to the patient's back skin when it is pasted and fixed there. This also ensures a tighter bond between the fixing ring 3 and the patient's back skin, preventing the cleaning solution from leaking out between the fixing ring 3 and the patient's back skin.
[0034] In this embodiment, the connecting part includes multiple support rods 8, which are evenly arranged circumferentially on the upper side of the fixing ring 3. The lower end of each support rod 8 is fixedly connected to the fixing ring 3, and the support rod 8 is also fixedly connected to the support ring 4. With this structure, the connecting part can connect the support ring 4 and the fixing ring 3. After the fixing ring 3 is pasted and fixed to the skin on the patient's back and surrounds the wound, the support rods 8 can also block the portions of the upper wall 1 and lower wall 2 located above the wound, making it difficult for these portions to enter the wound area and reducing the possibility of them obstructing the wound.
[0035] In this embodiment, the support ring 4 can also slide up and down on the support rod 8. The support ring 4 can slide up and down on the support rod 8 to adjust the gap between the support ring 4 and the fixing ring 3. While ensuring the gap between the support ring 4 and the fixing ring 3 is sufficient for the cleaning fluid to pass through, the gap can also be reduced as much as possible, that is, the depth of the wound from the side of the support ring 4 facing away from the fixing ring 3 can be reduced as much as possible, thereby reducing the obstruction of the cleaning operation by the pressure injury care dressing change auxiliary device of this invention.
[0036] In this embodiment, a circular hole is formed on the support ring 4 corresponding to the position of each support rod 8; the connecting part also includes a plurality of rubber rings 9 fixed in the plurality of circular holes one by one, the rubber rings 9 are arranged around the corresponding support rod 8, and the annular hole of the rubber ring 9 is interference fit with the support rod 8.
[0037] Because the annular hole of the rubber ring 9 is interference-fitted with the support rod 8, the annular hole of the rubber ring 9 can be tightly clamped onto the support rod 8. When the support ring 4 is not pushed towards or away from the patient's back skin, the support ring 4 cannot move on the support rod 8. At this time, the support rod 8 can be fixedly connected to the support ring 4. When the support ring 4 is pushed forcefully towards or away from the patient's back skin, the support ring 4 can move up and down on the support rod 8.
[0038] In this embodiment, the dressing change auxiliary device for pressure injury care of this utility model further includes an adhesive tape 10 and a flexible sleeve 11. The adhesive tape 10 is annular and located inside the fixing ring 3, with the adhesive tape and the fixing ring 3 arranged coaxially. The flexible sleeve is made of a rubber film, and both the upper and lower ends of the flexible sleeve 11 are open. The edge of the upper opening of the flexible sleeve 11 is fixedly connected to the edge of the annular hole of the fixing ring 3, and the edge of the lower opening of the flexible sleeve 11 is fixedly connected to the edge of the adhesive tape 10. Specifically, the edge of the upper opening of the flexible sleeve 11 can be fixedly connected to the edge of the annular hole of the fixing ring 3 by adhesive bonding, so that cleaning fluid cannot pass between the edge of the upper opening of the flexible sleeve 11 and the edge of the annular hole of the fixing ring 3; the edge of the lower opening of the flexible sleeve 11 can be fixedly connected to the edge of the adhesive tape 10 by adhesive bonding, so that cleaning fluid cannot pass between the edge of the lower opening of the flexible sleeve 11 and the edge of the adhesive tape 10.
[0039] After positioning the patient on their side with their back facing upwards, adhesive tape is applied to the patient's back skin, surrounding the wound. Then, the fixation ring 3 is applied to the patient's back skin, surrounding the adhesive tape. When rinsing the wound, the adhesive tape 10 and the flexible sleeve 11 prevent the cleaning fluid from flowing between the flexible sleeve 11 and the patient's back skin, further reducing the possibility of leakage from between the fixation ring 3 and the patient's back skin.
[0040] In this embodiment, the dressing change auxiliary device for pressure injury care of this utility model also includes a drainage pipe, which is fixedly connected to the lower wall 2 and used to drain the liquid in the receiving cavity 5.
[0041] When the fixation ring 3 is attached and fixed to the skin on the patient's back and surrounds the wound, the connection point between the drain pipe and the lower wall 2 is located below the wound. This allows for simultaneous wound cleaning and drainage of the cleaning fluid entering the receiving cavity 5 (located below the wound) into a collection container via the drain pipe. This reduces the possibility of cleaning fluid overflowing from the support ring 4.
[0042] In this embodiment, the drainage pipeline includes a squeezeable balloon 12, a first pipe body 13, a first one-way valve 14, a second one-way valve 15, and a second pipe body 16. The squeezeable balloon 12 is made of rubber material, which is elastic. After the squeezeable balloon 12 is squeezed and released, it can recover its shape under its own elasticity. One end of the first pipe body 13 is fixedly connected to the lower wall 2 and communicates with the receiving cavity 5. The other end of the first pipe body 13 is connected to the inlet end of the first one-way valve 14. The outlet end of the first tube 14 is fixedly connected to the hand-squeezable balloon 12 and communicates with the inner cavity of the hand-squeezable balloon 12. Specifically, the first one-way valve 14 only allows the cleaning fluid in the first tube 13 to enter the inner cavity of the hand-squeezable balloon 12. The inlet end of the second one-way valve 15 is fixedly connected to the hand-squeezable balloon 12 and communicates with the inner cavity of the hand-squeezable balloon 12. One end of the second tube 16 is fixedly connected to the outlet end of the second one-way valve 15. Specifically, the second one-way valve 15 only allows the cleaning fluid in the inner cavity of the hand-squeezable balloon 12 to enter the second tube 16.
[0043] During wound cleaning, the hand-operated balloon 12 can be alternately squeezed and released. When the balloon is squeezed, the cleaning fluid inside is forced through the second one-way valve 15 into the second tube 16 and then discharged into the collection container. When the balloon is released, it recovers its shape due to its elasticity. During this recovery, the balloon draws the cleaning fluid from the receiving cavity 5 into the balloon through the first tube 13 and the first one-way valve 14. By continuously squeezing and releasing the balloon, the cleaning fluid in the receiving cavity 5 is continuously drained. Furthermore, by drawing the cleaning fluid out of the receiving cavity 5 through the balloon, the cleaning fluid can be drained more quickly, further reducing the possibility of the cleaning fluid overflowing from the support ring 4.
[0044] In this embodiment, the dressing change assist device for pressure injury care according to the present invention further includes a collection bag 17 fixedly connected to the other end of the second tube 16. The cleaning fluid discharged from the second tube 16 can be directly discharged into the collection bag 17, eliminating the need to find a separate container to collect the cleaning fluid discharged from the receiving cavity 5, making the dressing change assist device for pressure injury care according to the present invention more convenient to use.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
