Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a gauze replacement auxiliary tool. BACKGROUND

[0002] There is a traumatic operation of placing a tracheostomy cannula into the trachea of a patient by incision on the neck of the patient in clinic, and the operation can ensure smooth breathing of the patient, so that the breathing auxiliary instrument can smoothly input oxygen-containing gas into the respiratory tract of the patient, thereby providing a stable and unobstructed breathing passage for a critical patient or a patient who needs to use mechanical ventilation for a long time.

[0003] The part of the tracheostomy cannula outside the patient's body is provided with an oval plate, which is used to stabilize the relative position relationship between the tracheostomy cannula and the airway of the patient. In actual use, Y-shaped gauze for buffering and absorbing wound secretions needs to be placed between the skin of the neck of the patient and the oval plate. This layer of Y-shaped gauze needs to be replaced while the patient's wound is regularly cared for. However, the actual operation of passing the new gauze through the gap between the plate and the skin of the patient is very difficult. When the operation is completed, the medical staff mainly uses the Y-shaped member with branches to push the gauze into the gap between the plate and the skin. However, when the member pushing the gauze is withdrawn along the original path, the gauze will move a distance in the direction outside the gap under the action of the Y-shaped member, which will cause the gauze to not be in close contact with the wound, and will also affect the patient's experience.

[0004] Therefore, a disposable auxiliary tool capable of conveniently placing Y-shaped gauze under a tracheostomy cannula is designed. The auxiliary tool is specifically a gauze replacement auxiliary tool. CONTENT OF THE UTILITY MODEL

[0005] In order to overcome the problems in the background art, the utility model adopts the following technical solutions:

[0006] A gauze replacement auxiliary tool comprises: an execution head, which comprises two mirror image arranged push arms, and an arc-shaped gap is formed between the push arms; the arc-shaped gap is consistent with the outer contour of the tracheostomy cannula, and when the execution head enters the gap and moves towards the tracheostomy cannula, it will finally be clamped on the tracheostomy cannula, and at the same time, the Y-shaped gauze pressed tightly is moved to the position in contact with the wound of the patient. The execution head is always clamped on the tracheostomy cannula during the splitting process along with the easy-to-tear line, which can effectively prevent the Y-shaped gauze pushed to the wound from moving outward along the track when entering the gap. A handle, the handle has a proximal end connected to the execution head, and the handle has a distal end away from the execution head; the handle further comprises two mirror image arranged flaps, and the two flaps have an included angle; an easy-to-tear line comprises a plurality of linear array through holes arranged through the handle and the execution head, and the through holes are not consistent with the contour of the arc-shaped gap; when the two flaps move in opposite directions, the parts of the handle and the execution head on the two sides of the easy-to-tear line gradually separate in the direction from the distal end to the proximal end.

[0007] Furthermore, it also includes a positioning component, which comprises a connecting plate and several positioning posts. The connecting plate and the positioning posts are integrally connected, and the central axes of any two positioning posts are parallel to each other. The handle has several positioning holes extending through both sides of the tear line. When the positioning posts are connected to the positioning holes in a one-to-one correspondence, the connecting plate abuts against the outer wall of the handle. When the positioning component is connected to the handle, it restricts the portions on both sides of the tear line from moving away from each other, which helps prevent the tear line from being torn before the Y-shaped gauze is pushed to the position of contacting the patient's wound.

[0008] Furthermore, the positioning hole is disposed between the proximal end and the distal end, and the positioning holes on both sides of the tear line are symmetrically distributed about the tear line.

[0009] Furthermore, an arc-shaped groove is provided at one end of the connecting plate opposite to the handle.

[0010] Furthermore, it also includes a fixing component, which comprises a second connecting plate and several fixing posts. Each positioning post has a connecting hole, which is coaxial with the positioning post. The outer diameter of the connecting hole is not less than the outer diameter of the fixing post. When the positioning post is connected to the fixing post through the connecting hole in a one-to-one correspondence, the second connecting plate and the first connecting plate respectively abut against the opposite outer walls of the handle. The fixing component enhances the connection stability between the positioning component and the handle, ensuring that the positioning posts on the positioning component are simultaneously pressed inward by the multiple positioning holes and outward by the fixing posts within the connecting holes.

[0011] Furthermore, the axial height of the positioning post is the same as the axial height of the positioning hole, and the axial height of the fixing post is not greater than the axial height of the positioning post.

[0012] Furthermore, when the handle is connected to the actuator head, the thickness of the handle is the same as the thickness of the actuator head along the axial direction of the positioning hole. When the actuator head enters the gap under the elliptical plate, the handle, with the same thickness as the actuator head, has no gradient step at the connection point.

[0013] Furthermore, the handle and the actuator are made of the same material, and both the handle and the actuator are elastic. Once the arc-shaped notch is pressed against the blasting sleeve, the user can continue to push the handle into the gap and observe the deformation of the handle while feeling resistance, thus determining that the arc-shaped notch has aligned with the blasting sleeve.

[0014] Furthermore, along the direction from the distal end to the proximal end, the length of the push arm is greater than the outer diameter of the tracheostomy tube. This allows the arc-shaped notch formed between the two push arms to clamp the tracheostomy tube in a semi-enclosed manner, thereby facilitating the positioning operation of the actuator head and the Y-shaped gauze.

[0015] Furthermore, the number of fixed posts is at least four.

[0016] The beneficial effects of this utility model are:

[0017] 1. By incorporating easy-tear lines on the handle and actuator head, medical staff can use the actuator head's push arm to insert the Y-shaped gauze into the junction of the tracheostomy cannula and the patient's wound. They can then tear the flaps to the sides, disassembling the handle and actuator head along the easy-tear lines, allowing the gauze to be removed from opposite sides. The arc-shaped notch design ensures that the push arm maintains the position of the Y-shaped gauze while the actuator head is wrapped around the tracheostomy cannula before complete disassembly, preventing the gauze from being pulled out during the removal of auxiliary tools, thus providing excellent practicality.

[0018] 2. By setting positioning and fixing parts, the easy-tear thread can be effectively prevented from breaking prematurely when replacing the gauze. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] A yarn changing auxiliary tool, such as Figures 1-4 As shown, it includes: an execution head 1, comprising two mirror-mounted push arms 11, with an arc-shaped notch 12 formed between the push arms 11; the arc-shaped notch 12 matches the outer contour of the tracheostomy cannula, and when the execution head 1 enters the gap and moves towards the tracheostomy cannula, it will eventually lock onto the tracheostomy cannula, simultaneously moving the tightly pressed Y-shaped gauze to a position in contact with the patient's wound. Furthermore, the execution head 1 remains locked onto the tracheostomy cannula as it splits along the tear-resistant suture 3, effectively preventing the Y-shaped gauze pushed to the wound from moving outward along the trajectory it took to enter the gap. Handle 2 has a proximal end 21 connected to the actuator head 1 and a distal end 22 opposite to the actuator head 1; handle 2 also includes two mirror-arranged flaps 23 with an included angle between the two flaps 23; tear line 3 includes multiple through holes 31 arranged in a linear array through the handle 2 and the actuator head 1, the through holes 31 do not coincide with the outline of the arc-shaped notch 12; when the two flaps 23 move in opposite directions, they cause the parts of handle 2 and actuator head 1 on both sides of tear line 3 to gradually separate along the direction from distal end 22 to proximal end 21.

[0027] In some embodiments of this application, such as Figures 1-4 As shown, it also includes a positioning component 4, which comprises a connecting plate 41 and several positioning posts 42. The connecting plate 41 and the positioning posts 42 are integrally connected, and the central axes of any two positioning posts 42 are parallel to each other. The handle 2 has several positioning holes 24 through it on both sides of the tear line 3. When the positioning posts 42 are connected to the positioning holes 24 in a one-to-one correspondence, the connecting plate 41 abuts against the outer wall of the handle 2. When the positioning component 4 is connected to the handle 2, it restricts the portions on both sides of the tear line 3 from moving away from each other, which helps to prevent the tear line 3 from being torn before the Y-shaped gauze is pushed to the position of contacting the patient's wound.

[0028] In some embodiments of this application, such as Figures 1-4As shown, the positioning holes 24 are located between the proximal end 21 and the distal end 22, and the positioning holes 24 on both sides of the tear line 3 are symmetrically distributed about the tear line 3. Even if the tear line 3 between the positioning element 4 and the distal end 22 is torn due to accidental contact during operation, the remaining part of the tear line 3 will not be affected. Therefore, the positioning element 4 can prevent both the tear line 3 from tearing under force and the tear line 3 from tearing under the drive of the wing 23 during operation, thus ensuring the normal operation of yarn changing.

[0029] In some embodiments of this application, such as Figures 1-4 As shown, the end of the connecting plate 41 opposite to the handle 2 is provided with an arc-shaped groove 411. The curvature of the arc-shaped groove 411 is approximately the contour of the fingertip of a human finger. When the user grasps the handle 2 and pushes the Y-shaped gauze, he / she can press the arc-shaped groove 411 with his / her fingers to increase the contact friction and enhance the protection of the easy-tear line 3 by the positioning part 4.

[0030] In some embodiments of this application, such as Figures 1-4 As shown, it also includes a fixing component 5, which includes a connecting plate 2 51 and several fixing posts 52. The number of fixing posts 52 is at least four. The positioning post 42 is provided with a connecting hole 421, which is coaxial with the positioning post 42. The outer diameter of the connecting hole 421 is not less than the outer diameter of the fixing post 52. When the positioning post 42 is connected to the fixing post 52 one-to-one through the connecting hole 421, the connecting plate 2 51 and the connecting plate 1 41 respectively abut against the outer walls of the opposite sides of the handle 2. The setting of the fixing component 5 enhances the connection stability between the positioning component 4 and the handle 2, so that the positioning post 42 on the positioning component 4 is pressed and fixed inward by multiple positioning holes 24 and also pressed and fixed outward by the fixing post 52 in the connecting hole 421. This greatly increases the frictional force along the axial direction of the positioning post 42 on the positioning component 4, making it difficult for the positioning component 4 and the handle 2 to separate in case of accidental contact, thereby indirectly reducing the risk of the easy-tear line 3 being accidentally torn.

[0031] In some embodiments of this application, such as Figures 1-4 As shown, the axial height of the positioning post 42 is the same as the axial height of the positioning hole 24, and the axial height of the fixing post 52 is not greater than the axial height of the positioning post 42. When the handle 2 is connected to the actuator head 1, the thickness of the handle 2 is the same as the thickness of the actuator head 1 along the axial direction of the positioning hole 24. When the actuator head 1 enters the gap under the elliptical plate, the handle 2, which has the same thickness as the actuator head 1, has no gradient step at the connection point, so it can also smoothly enter the gap with the user's push. This prevents the gauze from getting stuck outside the tracheostomy cannula when changing Y-shaped gauze, thus not affecting the efficiency of wound care for the patient.

[0032] In some embodiments of this application, such as Figures 1-4As shown, the handle 2 and the actuator head 1 are made of the same material, and both are elastic. Once the arc-shaped notch 12 is pressed against the tracheostomy cannula, the user will feel resistance and observe the deformation of the handle 2 as they continue to push it into the gap, thus confirming that the arc-shaped notch 12 has aligned with the tracheostomy cannula. Furthermore, the surface structure of the patient's neck at the contact point with the tracheostomy cannula is uneven; the deformable handle 2 and actuator head 1 can better conform to the patient's skin when pushing the gauze into the gap, thereby reducing patient discomfort during care.

[0033] In some embodiments of this application, such as Figures 1-4 As shown, along the direction from the distal end 22 to the proximal end 21, the length of the push arm 11 is greater than the outer diameter of the tracheostomy tube. This allows the arc-shaped notch 12 formed between the two push arms 11 to clamp the tracheostomy tube in a semi-enclosed posture, which is beneficial for achieving the positioning operation of the actuator 1 and the Y-shaped gauze.
