Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a self-adhesive throat pad. Background Art

[0002] Emergency tracheotomy is a medical procedure that maintains the patient's respiratory function by making an incision in the trachea of ​​the neck and inserting a cannula made of metal or silicone. After the operation, the patient breathes through this cannula. One end of the cannula protrudes from the neck and is in direct contact with the outside air. The exposed part of the cannula on the neck is equipped with an oval cannula handle. Prolonged contact between the cannula handle and the skin may cause friction, which in turn causes damage to the skin at the wound.

[0003] In order to reduce the impact of this friction on the skin, clinically, after tracheotomy, in order to protect the patient's neck skin and reduce the friction between the cannula handle and the skin, disposable sterile cut gauze is usually used as a throat pad. However, this throat pad has some shortcomings, such as the square gauze has a low fit with the skin, which easily causes friction and affects the comfort of wearing. In addition, in the early stage of tracheotomy, due to the large amount of exudate and sputum in the patient's wound, the square gauze easily becomes moist, which not only increases the moisture level of the patient's skin around the fistula, but also may increase the risk of local infection and discomfort of the wound. In order to ensure the cleanliness and dryness of the cut gauze, it needs to be replaced frequently, which undoubtedly increases the economic burden of the patient and the workload of the nursing staff. Therefore, the present application provides a self-adhesive throat pad to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a self-adhesive throat pad to solve the problems that the existing throat pad has low fit with the skin, cannot effectively limit and fix the cannula and the cannula handle, and needs to be replaced frequently, which increases the economic burden on patients and the workload of nursing staff.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A self-adhesive throat pad comprises a sterile square gauze, wherein the sterile square gauze is symmetrically provided with a first Y-shaped groove and a second Y-shaped groove, a circular hole is provided in the middle of the sterile square gauze, and a straight groove is provided on the sterile square gauze, wherein the straight groove is connected to the circular hole, three adhesive plates are fixedly connected to the outer wall of one side of the sterile square gauze, and a protective film is adhered to the adhesive plates; a fixing component, wherein the fixing component is used to limit and fix the cannula handle, and the fixing component is connected to the sterile square gauze.

[0007] Optionally, the fixing assembly includes a first fixing plate and a second fixing plate installed on the inner wall of the sterile square gauze.

[0008] Optionally, three elliptical elastic plates are fixedly connected to the first fixing plate and the second fixing plate.

[0009] Optionally, two ventilation holes are provided on the elliptical elastic plate.

[0010] Optionally, the elliptical elastic plate is installed with two first C-shaped elastic plates and two second C-shaped elastic plates.

[0011] Optionally, two first ventilation holes are formed on the first fixing plate.

[0012] Optionally, two second ventilation holes are formed on the second fixing plate.

[0013] Optionally, the elliptical elastic plate is covered with a sterile foam pad and the inner wall of the elliptical elastic plate is attached to the outer wall of the sterile foam pad.

[0014] Optionally, two first limiting grooves and two second limiting grooves are formed on the sterile foam pad.

[0015] Optionally, the sterile gauze is a double-layer structure.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, a fixing component is provided to limit and fix the cannula and the cannula handle. Such a setting can prevent the cannula handle from rubbing against the patient's throat skin and causing damage to the skin at the wound. In addition, the fixing component can also limit and fix the cannula and the cannula handle, effectively preventing the patient from accidentally touching the cannula handle and causing displacement, causing discomfort to the patient. At the same time, the fixing component can absorb the exudate from the patient's wound, effectively reducing the risk of local infection and discomfort of the wound.

[0018] By setting up a sterile foam pad, the exudate from the patient's wound can be absorbed, effectively reducing the risk of local infection and discomfort of the wound and improving the patient's comfort.

[0019] By providing an elliptical elastic plate, a first fixing plate and a second fixing plate, the cannula and the cannula handle can be fixed and limited to support, thereby preventing the patient from moving the cannula and the cannula handle inadvertently, causing discomfort in the patient's throat or even suffocation. At the same time, it can also prevent the friction between the cannula handle and the skin from causing damage to the wound and being detrimental to wound healing.

[0020] The sterile foam pad cooperates with the elliptical elastic plate, the first fixing plate and the second fixing plate to prevent local infection caused by exudate from the patient's wound, and can also limit and fix the cannula handle and cannula to prevent the cannula handle and cannula from rubbing against the wound skin, which is not conducive to wound healing.

[0036] like Figure 1 Hezhi Figure 6 As shown, an embodiment of the present invention provides a self-adhesive throat pad, comprising a sterile square gauze 1, the sterile square gauze 1 symmetrically provided with a first Y-shaped groove 101 and a second Y-shaped groove 102, a circular hole 104 provided in the middle of the sterile square gauze 1, and a straight groove 105 provided on the sterile square gauze 1, the straight groove 105 being connected to the circular hole 104, and three adhesive plates 103 being fixedly connected to the outer wall of one side of the sterile square gauze 1, and a protective film being pasted on the adhesive plate 103.

[0037] When medical staff use this device to fix the cannula and cannula handle on the patient's wound, they only need to tear off the protective film on the surface of the adhesive plate 103 first. The protective film is used to prevent the colloid on the surface of the adhesive plate 103 from being contaminated during storage. Then align the circular hole 104 on the device with the cannula and stick it to the patient's throat. Since the device is provided with a first Y-shaped groove 101 and a second Y-shaped groove 102, the first Y-shaped groove 101 and the second Y-shaped groove 102 will open the gap of the Y-shaped groove according to the contour of the patient's throat when in use, so that it can better fit the patient's throat skin surface. A self-adhesive throat pad includes a fixing component, which is used to limit and fix the cannula handle. The fixing component is connected to the sterile square gauze 1.

[0038] like Figures 3 to 6 As shown, the fixing assembly includes a first fixing plate 4 and a second fixing plate 5 installed on the inner wall of the sterile square gauze 1, the first fixing plate 4 is provided with two first ventilation holes 401, the second fixing plate 5 is provided with two second ventilation holes 501, the first fixing plate 4 and the second fixing plate 5 are fixedly connected with three elliptical elastic plates 3, the elliptical elastic plate 3 is provided with two ventilation holes 303, and the elliptical elastic plate 3 is respectively installed with two first C-type elastic plates 301 and two second C-type elastic plates 302.

[0039] Specifically, the sterile square gauze 1 has a double-layer structure, and the first fixing plate 4 and the second fixing plate 5 are symmetrically installed on the top inner wall and the bottom inner wall of the sterile square gauze 1 respectively. The first fixing plate 4 and the second fixing plate 5 are both sheet structures, and the outline is a "U" shape. The size outlines of the two are equal and parallel to each other. Two first ventilation holes 401 and two second ventilation holes 501 are respectively provided on the first fixing plate 4 and the second fixing plate 5. The three elliptical elastic plates 3 are fixedly connected to the two ends and the middle of the first fixing plate 4 and the second fixing plate 5 respectively. Two ventilation holes 303 are symmetrically provided on the outer walls on both sides of the three elliptical elastic plates 3. There are two first C-type elastic plates 301, which are symmetrically installed on both sides of the elliptical elastic plate 3 and on the outer wall close to the circular hole 104. There are also two second C-type elastic plates 302, which are symmetrically installed on the outer walls at both ends of the elliptical elastic plate 3.

[0040] When using this device, the elliptical elastic plate 3, the first fixing plate 4 and the second fixing plate 5 cooperate with each other to fix the cannula, and the arc-shaped outer walls at one end of the three elliptical elastic plates 3 cooperate with the sterile square gauze 1 to press against the outer wall of the cannula to fix the cannula. When the patient moves accidentally, the first C-shaped elastic plate 301 on the elliptical elastic plate 3 will be deformed, and the two ends of the first C-shaped elastic plate 301 will bend toward the middle, and will return to their original shape under the action of elasticity, playing a buffering role and fixing the cannula. When the patient touches the cannula handle, the cannula handle will move toward the patient's throat. At this time, the second C-shaped elastic plate 302 on the elliptical elastic plate 3 will be deformed, and its two ends will bend toward the middle. Under the action of elasticity, the cannula handle will be pressed, playing a limiting role and effectively preventing the cannula handle from rubbing against the patient's wound skin.

[0041] The vent holes 303, the first vent holes 401 and the second vent holes 501 are respectively provided on the elliptical elastic plate 3, the first fixing plate 4 and the second fixing plate 5 to keep the skin of the patient's wound dry and facilitate air flow. The above structural arrangement can fix and limit the cannula and the cannula handle to prevent the patient from moving the cannula and the cannula handle in an unintended manner, thereby preventing the patient from causing throat discomfort or even suffocation. At the same time, it can also prevent the cannula handle from rubbing against the skin to avoid damage to the wound, which is not conducive to wound healing.

[0042] The elliptical elastic plate 3 is provided with a sterile foam pad 2 and the inner wall of the elliptical elastic plate 3 is fitted on the outer wall of the sterile foam pad 2. Two first limiting grooves 201 and two second limiting grooves 202 are respectively provided on the sterile foam pad 2. Specifically, the elliptical elastic plate 3 is provided with a sterile foam pad 2, wherein the outer wall of the sterile foam pad 2 is tightly fitted with the inner wall of the elliptical elastic plate 3. There are two first limiting grooves 201, which are symmetrically installed on the outer wall of the bottom and top of the sterile foam pad 2 close to the circular hole 104. There are also two second limiting grooves 202, which are symmetrically installed on the outer walls on both sides of the sterile foam pad 2. The outer contours of the first limiting groove 201 and the second limiting groove 202 are respectively adapted to the second C-type elastic plate 302 and the first C-type elastic plate 301.

[0043] Since the sterile foam pad 2 itself has adsorption properties, it can absorb the exudate from the patient's wound and effectively keep the patient's wound dry and clean. The sterile foam pad 2 itself is also elastic, so the two groups of first limiting grooves 201 and second limiting grooves 202 can be deformed along with the deformation of the second C-shaped elastic plate 302 and the first C-shaped elastic plate 301 on the elliptical elastic plate 3. The above structural setting can effectively absorb the exudate from the patient's wound. This function significantly reduces the risk of local infection of the wound, greatly alleviates the patient's discomfort, and greatly improves the patient's comfort during treatment.

[0044] The working principle of the technical solution provided by the utility model is as follows:

[0045] When medical staff use this device to fix the cannula and cannula handle on the patient's wound, they first tear off the protective film on the surface of the adhesive plate 103. The protective film is used to prevent the colloid on the surface of the adhesive plate 103 from being contaminated during storage. Then align the circular hole 104 on the device with the cannula and stick it on the patient's throat. Because this device is provided with a first Y-shaped groove 101 and a second Y-shaped groove 102, the gap of the Y-shaped groove will be opened according to the skin contour when pasting, so that it can better fit the throat skin. The elliptical elastic plate 3, the first fixing plate 4 and the second fixing plate 5 cooperate with each other to fix the cannula. The arc-shaped outer wall at one end of the three elliptical elastic plates 3 cooperates with the sterile square gauze 1 to resist the outer wall of the cannula.

[0046] When the patient makes an accidental movement, the two first C-shaped elastic plates 301 on the elliptical elastic plate 3 will be deformed, with both ends bending toward the middle and recovering by elasticity to play a buffering role and fix the cannula. The patient hits the cannula handle and the cannula handle moves toward the throat. At this time, the two second C-shaped elastic plates 302 on the elliptical elastic plate 3 will also be deformed, with both ends bending toward the middle and supporting the cannula handle by elasticity to play a limiting role and prevent the cannula handle from rubbing against the wound skin.

[0047] The ventilation holes 303, the first ventilation holes 401 and the second ventilation holes 501 respectively provided on the elliptical elastic plate 3, the first fixing plate 4 and the second fixing plate 5 are intended to keep the patient's wound skin dry and facilitate air flow, while reducing its weight and improving the patient's wearing comfort. Since the sterile foam pad 2 has adsorption properties, it can absorb wound exudate and keep the wound dry and clean, and it itself is also elastic, so the first limiting groove 201 and the second limiting groove 202 respectively provided on the sterile foam pad 2 can deform as the second C-shaped elastic plate 302 and the first C-shaped elastic plate 301 on the elliptical elastic plate 3 are deformed.

[0048] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the preferred embodiments of this invention, but those skilled in the art can fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion about the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
