Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of indwelling needle, and particularly to an indwelling needle connector fixing patch. BACKGROUND
[0002] In clinical practice, intravenous injection treatment for patients is generally performed by pre-attaching an indwelling needle to the arm of a patient. The connector of the indwelling needle usually adopts a three-way interface, i.e., one interface is an outlet, the outlet is in communication with the needle part through a transfusion tube, and the other two interfaces are a positive pressure interface and a standby interface with a heparin cap. The outlet and the positive pressure interface are connected by a main tube, and the standby interface with the heparin cap is in communication with the side wall of the main tube through a side tube.
[0003] In the prior art, the connector of the indwelling needle is usually directly attached to the arm of a patient by using a medical adhesive tape or fixed to the arm of a patient by using a medical adhesive tape in a winding manner. This at least has the following two problems:
[0004] First, the connector of the indwelling needle is made of hard plastic material, and when the adhesive tape is used to attach the connector of the indwelling needle to the arm of a patient, the connector of the indwelling needle can cause pressure sores on the arm of the patient.
[0005] Second, the process of intravenous injection treatment for a patient can be performed multiple times, and each time the nurse needs to connect the transfusion tube with the positive pressure interface of the connector of the indwelling needle. At this time, the connector of the indwelling needle is attached to the arm of the patient by using the medical adhesive tape, thus causing inconvenience to the operation of the connection process. SUMMARY
[0006] The utility model aims to at least solve one of the technical problems in the related art to a certain extent: to provide an indwelling needle connector fixing patch which can fix the connector of the indwelling needle to the arm of a patient without causing pressure sores and can be removed.
[0007] To this end, one object of the utility model is to provide an indwelling needle connector fixing patch, which comprises a patch-shaped patch, the back of the patch has a sticking layer, and the front of the patch is provided with a buckle assembly for placing the connector of the indwelling needle. The utility model is characterized in that: the front of the patch has a placing area for accommodating the connector of the indwelling needle, and the buckle assembly comprises a left limiting piece, a lower limiting piece, a right limiting piece and a movable limiting piece arranged in sequence around the outer contour of the connector of the indwelling needle in the placing area.
[0008] The left limiting piece, the lower limiting piece and the right limiting piece are arranged on the left side, the right side and the lower side of the connector of the indwelling needle in the placing area, respectively.
[0009] The movable limiting part is located at the connection between the main pipe and the side pipe of the indwelling needle connector, and has a limiting state abutting against the indwining needle connector and an avoiding state allowing the indwining needle connector to be separated from the buckle assembly at the position of the movable limiting part. The movable limiting part is switched freely between the limiting state and the avoiding state, so that the indwining needle connector can be conveniently fixed on or removed from the buckle assembly. When the indwining needle connector is placed on the buckle assembly, the indwining needle connector does not have a pressing force on the patch in the thickness direction, so as to avoid pressure sores on the skin of the patient's arm. When the medical staff needs to connect the infusion tube to inject medicine, the indwining needle connector can be conveniently removed from the buckle assembly, so as to facilitate the connection process.
[0010] According to an example of the utility model, the lower ends of the left limiting part and the right limiting part are fixed to the patch, and the upper ends thereof have inwardly extending flanges, which abut against the indwining needle connector and limit the movement of the indwining needle connector in the thickness direction of the patch. The flanges at the upper ends of the left limiting part and the right limiting part limit the movement of the indwining needle connector in the thickness direction of the patch, so as to avoid accidental separation of the indwining needle connector from the patch.
[0011] According to an example of the utility model, the movable limiting part is an elastic air bag, which is in the limiting state of abutting against the outer sidewall of the indwining needle connector under the action of the elastic restoring force of the elastic air bag, or is deformed to the avoiding state when the indwining needle connector applies a force to the position of the elastic air bag, so as to separate the indwining needle connector from the buckle assembly. The elastic restoring force of the elastic air bag limits the indwining needle connector in the buckle assembly, and when the indwining needle connector is grabbed and a certain degree of external force is applied to the elastic air bag, the elastic air bag is driven to shrink and deform, so as to form an avoiding space, and the indwining needle connector can move from the position of the elastic air bag and finally separate from the buckle assembly.
[0012] According to an example of the utility model, the movable limiting part includes a ring formed by connecting the elastic sheets at the top and bottom in the vertical direction, the width of the middle part of the ring is greater than the width of the two ends, the lower end of the ring is fixed to the patch through the connecting rod, and the upper end of the ring extends above the indwining needle connector at the position between the main pipe and the side pipe of the indwining needle connector, and the part between the middle and the lower end of the ring abuts against the main pipe and the side pipe of the indwining needle connector.
[0013] According to an example of the utility model, the ring and the connecting rod are in an integrated structure.
[0014] According to an example of the utility model, the ring is made of elastic rubber material.
[0015] According to an example of the utility model, the back of the patch has a buffer layer, and the adhesive layer is located on the side of the buffer layer away from the patch.
[0016] The above technical solution has the following advantages or beneficial effects: First, the patch adheres to the patient's arm skin through the adhesive layer on the back, and then the indwelling needle connector is placed on the buckle assembly. At this time, the indwelling needle connector does not exert pressure on the patient's arm, thus effectively avoiding pressure sores. Second, the movable limiting member in the buckle assembly can freely switch between the limiting state and the avoidance state. Therefore, the indwelling needle connector can be well fixed in the buckle assembly when the movable limiting member is in the limiting state, and when switched to the avoidance state, the indwelling needle connector is removed from the position of the movable limiting member. Finally, after removing the indwelling needle connector, it is convenient to connect the indwelling needle connector to the external infusion tube.
[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] The indwelling needle connector fixing sticker according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0029] like Figure 3 As shown, existing indwelling needles for intravenous injection generally include an indwelling needle tip, an indwelling needle connector, and a tubing. The indwelling needle connector adopts a three-way structure. Specifically, the indwelling needle connector includes one outlet and two inlets. One of the two inlets is a positive pressure interface, and the other is a spare interface with a heparin cap. The inlet and the positive pressure interface are located at opposite ends of the main tube 7.1. The spare interface is obliquely connected to the outer wall of the main tube 7.1 via a side tube 7.2 and communicates with the inner lumen of the main tube 7.1. The indwelling needle tip is connected to the outlet of the indwelling needle connector via a tubing. During intravenous injection, the infusion tubing is connected to the positive pressure interface, while the spare interface is used for the infusion of other medications or blood transfusions.
[0030] This utility model provides an indwelling needle connector fixing patch, as shown in the figure. It includes a sheet-like patch 1, with an adhesive layer 2 on the back side of the patch 1 and a snap-fit assembly for holding the indwelling needle connector 7 on the front side. The patch 1 has a placement area 8 for accommodating the indwelling needle connector 7 on the front side. The snap-fit assembly includes a left limiting member 3, a lower limiting member 4, a right limiting member 5, and a movable limiting member 6 arranged sequentially around the outer contour of the indwelling needle connector 7 in the placement area 8.
[0031] The left limiting component 3, the lower limiting component 4, and the right limiting component 5 are respectively arranged on the left, right, and lower sides of the indwelling needle connector 7 in the placement area 8;
[0032] The movable limiting member 6 is located at the connection between the main tube 7.1 and the side tube 7.2 of the indwelling needle connector 7, and the movable limiting member 6 has a limiting state that abuts against the indwelling needle connector 7 and a avoidance state that allows the indwelling needle connector 7 to disengage from the buckling assembly through the position of the movable limiting member 6.
[0033] Specifically, in the above embodiments, the patch 1 and the adhesive layer 2 on the back of the patch 1 can be made of existing medical dressing materials. The adhesive layer 2 is covered with a release paper. Before use, medical staff only need to tear off the release paper and then apply the back of the patch 1 to the appropriate position on the patient's arm.
[0034] Preferably, the lower ends of the left and right limiters 3 and 5 are fixed to the patch 1, and the upper ends thereof have inwardly extending flanges which abut against the indwelling needle connector 7 to limit the movement of the indwelling needle connector 7 in the thickness direction of the patch 1. Specifically, the lower ends of the left and right limiters 3 and 5 and the lower limiter 4 are fixed to the patch 1, the lower limiter 4 abuts against the end face of the outlet on the side where the hose is located, and the upper ends of the left and right limiters 3 and 5 have flanges which are inwardly convex, and the part of the flanges which abut against the indwelling needle connector 7 forms an arc surface which matches the outer contour of the indwelling needle connector 7, so that the flanges can better fit the outer surface of the indwelling needle connector 7 and limit the movement of the indwelling needle connector 7 in the thickness direction.
[0035] Based on one of the preferred examples of the movable limiter 6 in the above embodiment: as shown in Figure 7 The movable limiter 6 is an elastic air bag 6.1 which is located at the angle position where the main pipe 7.1 and the side pipe 7.2 of the indwelling needle connector 7 are connected, and abuts against the left, right and lower sides of the indwelling needle connector 7 when the indwelling needle connector 7 is placed on the patch 1, and is in a limiting state, and under the action of the elastic restoring force of the elastic air bag 6.1, the elastic air bag 6.1 abuts against the outer side wall of the indwelling needle connector 7, i.e. the elastic air bag 6.1 abuts against the right side of the main pipe 7.1 and the upper side of the side pipe 7.2 at the same time. When the medical staff needs to remove the indwelling needle connector 7, the medical staff grabs the indwelling needle connector 7 and applies a force to the position where the elastic air bag 6.1 is located through the indwelling needle connector 7, so that the elastic air bag 6.1 deforms, and the deformed elastic air bag 6.1 avoids the movement path of the indwelling needle connector 7 from the buckle assembly, so that the indwelling needle connector 7 can be removed from the buckle assembly, and at this time, the deformed state of the elastic air bag 6.1 under the action of the external force is an avoiding state. Of course, in this embodiment, the medical staff can directly press the elastic air bag 6.1 with a finger, so that the elastic air bag 6.1 is switched from the limiting state to the avoiding state, and thus the medical staff can easily remove the indwelling needle connector 7 from the position where the elastic air bag 6.1 avoids the indwelling needle connector 7. The biggest advantage of this embodiment is that the medical staff can complete the removal of the indwelling needle connector 7 with one hand.
[0036] Based on another preferred example of the movable limiter 6 in the above embodiment: as shown in Figure 8As shown, the movable limiting member 6 includes a ring 6.2, which is a ring structure formed by connecting elastic sheets made of elastic material end to end in a vertical direction. The width of the middle position of the ring 6.2 is greater than the width of the two ends. The lower end of the ring 6.2 is fixed to the patch 1 by a connecting rod 6.3. The upper end of the ring 6.2 extends from the position between the main tube 7.1 and the side tube 7.2 of the indwelling needle connector 7 to the top of the indwelling needle connector 7, and the portion between the middle and the lower end of the ring 6.2 abuts against the main tube 7.1 and the side tube 7.2 of the indwelling needle connector 7. Specifically, as... Figure 8 As shown, taking the plane containing the line connecting the center of the main tube 7.1 and the center of the side tube 7.2 as the reference plane, the ring 6.2 has a rhomboid structure. The middle position of the ring 6.2, which has a larger width dimension, is located above the cover reference plane. The outer walls of the ring 6.2, located between the middle and lower positions, are attached to the corresponding main tube 7.1 and side tube 7.2. At this time, the indwelling needle connector 7 is... Figure 8 During upward movement, the frictional resistance between the outer wall of the ring 6.2 and the outer walls of the main tube 7.1 and side tube 7.2 causes the lower half of the ring 6.2 to be stretched, while the upper half remains unfolded. This effectively prevents the indwelling needle connector 7 from detaching from the ring 7, ensuring that the indwelling needle connector 7 will not accidentally detach due to inertia during the patient's arm movement. When medical staff need to remove the indwelling needle connector 7, they only need to grasp the upper end of the ring 6.2 and pull it to retract the entire ring 6.2 inward into a strip shape. At this time, the outer wall of the ring 6.2 detaches from the indwelling needle connector 7, thus facilitating its removal. In this embodiment, since the ring 6.2 is annular, the process of pulling the upper end of the ring 6.2 can be achieved by inserting a finger into the ring 6.2 and pulling upward to retract the ring 6.2, ultimately allowing the medical staff to remove the indwelling needle connector 7 with one hand. Similarly, when placing the indwelling needle connector 7, the indwelling needle connector 7 can be pressed flattened while simultaneously abutting against the left limiting member 3, the lower limiting member 4, and the right limiting member 5. At this point, the indwelling needle connector 7 is in place. By pulling the end of the ring 6.2, the ring 6.2 is pulled out from between the main tube 7.1 and the side tube 7.2 of the indwelling needle connector 7. After releasing the hand, the ring 6.2 returns to its original position under the action of its own elastic restoring force. Figure 8 The state shown.
[0037] Furthermore, the ring 6.2 and the connecting rod 6.3 are an integral structure.
[0038] Furthermore, the ring 6.2 is made of elastic rubber material.
[0039] In a preferred embodiment as described above, the back of the patch 1 has a buffer layer, and the adhesive layer 2 is located on the side of the buffer layer opposite to the patch. Specifically, the buffer layer is a silicone layer or a foam layer made of foam material.

[0041] For those skilled in the art, after reading the above description, various changes and modifications will undoubtedly be apparent. Therefore, the appended claims should be considered as covering all changes and modifications within the true intent and scope of the present application. Any and all equivalent ranges and contents within the scope of the claims should be considered as still within the intent and scope of the present application.
