Description

Technical Field

[0001] This utility model relates to the field of infusion set technology, specifically to an infusion set needle anti-dislodgement device. Background Technology

[0002] Intravenous infusion is a common treatment method in medical care. However, during prolonged infusions, the needle of a traditional infusion set is prone to detaching from the infusion bottle due to various reasons (such as patient movement or external force), leading to interruption of the infusion. This not only affects the treatment effect but may also cause unnecessary pain and risks to the patient.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an infusion set needle anti-dislodgement device in order to achieve a more practical purpose. Utility Model Content

[0004] The purpose of this invention is to provide a device to prevent the insertion needle of an infusion set from falling off, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an infusion set needle anti-dislodgement device, comprising a needle anti-dislodgement assembly, wherein an infusion plug is provided at the center of the needle anti-dislodgement assembly, and an infusion tube branch extends from the bottom of the infusion plug. The needle anti-dislodgement assembly includes a positioning piece, an extension piece, an anti-slip edging, a side plate, a lever, and an inner plate. An extension piece is provided on one outer side of the positioning piece, and side plates are provided on both horizontal sides of the positioning piece. The side plates are positioned on the upper sides of the positioning piece and are symmetrically distributed around the central axis of the extension piece. A lever is provided on the outer side of the side plate, and the lever is inclined toward one end of the extension piece. An inner plate is provided on the top inner side of the side plate, and the inner plate has an arc-shaped structure. An anti-slip edging is provided on the bottom arc edge of the extension piece. An infusion set bottle stopper is engaged on the inner side of the inner plates on both sides, and an infusion bottle body is provided on the top of the inner plate.

[0006] Furthermore, the pin anti-dislodgement assembly also includes an anti-deformation groove and a through groove. The anti-deformation groove is provided on the top of the inside of the side plate, and multiple sets of anti-deformation grooves are arranged in an array. The through groove is provided on the bottom of the side plate.

[0007] Furthermore, the positioning piece, extension piece, side plate, paddle, and inner plate are integrally formed.

[0008] Furthermore, the upper surface of the inner plate is arc-shaped.

[0009] Furthermore, the extension piece and the side plates on both sides are arranged in an obliquely symmetrical manner.

[0010] Furthermore, the side plate is connected to the infusion set stopper by an interlocking mechanism.

[0011] This utility model provides a device to prevent the insertion needle of an infusion set from falling off, which has the following beneficial effects:

[0012] 1. In this utility model, the entire needle anti-dislodgement assembly serves as the main structure of the anti-dislodgement device. The needle anti-dislodgement assembly uses a positioning plate and a side plate as the main load-bearing components and adopts an integral molding structure. When inserting the needle, the inner plate can utilize its arc-shaped upper surface structure to partially tilt the side plate outward, locking the inner plate into the outer ring of the top wall of the infusion set stopper. By using the locking method, the needle can be effectively prevented from accidentally dislodging during infusion, thus improving infusion safety. The entire structure is simple, easy to operate, and easy for medical personnel to use and maintain.

[0013] 2. In this utility model, when the infusion bottle body needs to be replaced after the infusion set stopper is connected to the infusion plug, medical staff can press with one hand, using the index and middle fingers to press the levers on both sides, and the index finger to press the anti-slip edge on the bottom side of the positioning plate. This makes it easy to apply force with one hand to tilt the side plate outward, so that the needle anti-dislodgement component is removed from the infusion set stopper. Compared with a single infusion plug, it is easier to replace the infusion bottle body, improving portability.

[0014] The positioning plates on both sides adopt an inclined structure, and the side plates on both sides also adopt an inclined design that moves closer to the positioning plates, which can better adapt to the hand structure, conform to the principle of mechanics, and improve the ease of use.

[0015] 3. In this utility model, the internal structure of the side plate adopts the design of anti-deformation groove and through groove to avoid the arc-shaped side plate from breaking when it tilts outward, so that the side plate has a certain elastic restoring characteristic and extends the service life of the component.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an infusion set needle anti-dislodgement device, including a needle anti-dislodgement component 1. An infusion plug 5 is located at the center of the needle anti-dislodgement component 1, and an infusion tube branch 4 extends from the bottom of the infusion plug 5. The needle anti-dislodgement component 1 includes a positioning piece 101, an extension piece 102, an anti-slip edging 103, a side plate 104, a lever 105, and an inner plate 107. An extension piece 102 is located on one outer side of the positioning piece 101, and side plates 104 are located on both horizontal sides of the positioning piece 101. The side plates 104 are positioned on the upper sides of the positioning piece 101 and are symmetrically distributed along the central axis of the extension piece 102. A lever 105 is located on the outer side of the side plate 104, and the lever 105 is inclined towards one end of the extension piece 102. An inner plate is located on the inner side of the top of the side plate 104. 107, the inner plate 107 has an arc-shaped structure, the bottom arc edge of the extension piece 102 is provided with an anti-slip edge 103, the inner sides of the two inner plates 107 are engaged with the infusion set bottle stopper 2, and the top of the inner plate 107 is provided with the infusion bottle body 3; the needle anti-dislodgement component 1 also includes an anti-deformation groove 106 and a through groove 108, the inner top of the side plate 104 is provided with an anti-deformation groove 106, and multiple sets of anti-deformation grooves 106 are arranged in an array, and the bottom of the side plate 104 is provided with a through groove 108; the positioning piece 101, the extension piece 102, the side plate 104, the lever 105 and the inner plate 107 are integrally formed; the upper surface of the inner plate 107 is arc-shaped; the extension piece 102 and the two side plates 104 are obliquely symmetrical; the side plate 104 is engaged and connected with the inner plate 107 and the infusion set bottle stopper 2.

[0024] The entire needle anti-dislodgement assembly 1 serves as the main structure of the anti-dislodgement device.
