Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a device for preventing needlestick injuries at an infusion port. Background Technology

[0002] Currently, patients with indwelling port-a-cath require weekly maintenance during treatment and monthly maintenance during treatment breaks. The existing method involves the operator pressing their index finger and thumb directly onto the port-a-cath to tighten the skin while simultaneously inserting the indwelling needle into the port-a-cath for flushing. After flushing, the needle is forcefully pulled out. However, because force is required to remove the needle, its inertia can cause it to rebound and injure the operator's index finger or thumb. Furthermore, there is a risk of pricking the index finger or thumb during the insertion of the needle back into the port-a-cath. Utility Model Content

[0003] The purpose of this utility model is to provide a device to prevent needle pricks in infusion ports, thereby solving the technical problem in the prior art where the infusion needle pricks the index finger or thumb when inserting or removing it from the infusion port seat. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides an anti-needle stick injury device for an infusion port, comprising a positioning component, a rotating component, and a connecting component, wherein the end of the positioning component and the end of the rotating component are rotatably connected through the connecting component, a first positioning notch is provided on the side wall of the positioning component, and a second positioning notch is provided on the side wall of the rotating component.

[0006] When the positioning member and the rotating member are in use, the first positioning notch and the second positioning notch correspond to each other and the first positioning notch and the second positioning notch together form a positioning hole, which can be fitted onto the infusion port needle.

[0007] Optionally, the positioning member has a receiving groove inside, and the rotating member can rotate into the receiving groove.

[0008] Optionally, the positioning element is provided with a positioning handle, and there is a gap between the positioning handle and the first positioning notch.

[0009] Optionally, the positioning handle is located at the free end of the positioning member, and the first positioning notch is located in the middle region of the positioning member and away from the free end of the positioning member.

[0027] This utility model provides a needle stick prevention device for infusion port, including a positioning component 1, a rotating component 2 and a connecting component 3, wherein the end of the positioning component 1 and the end of the rotating component 2 are rotatably connected by the connecting component 3, a first positioning notch 11 is provided on the side wall of the positioning component 1, and a second positioning notch 21 is provided on the side wall of the rotating component 2.

[0028] When the positioning element 1 and the rotating element 2 are in use, the first positioning notch 11 and the second positioning notch 21 correspond to each other and together form a positioning hole, which can be fitted onto the infusion port needle. This utility model provides an infusion port needle-prevention device. When maintaining a patient with an indwelling infusion port in clinical practice, the positioning element 1 and the rotating element 2 are rotated so that the first positioning notch 11 and the second positioning notch 21 align to form a positioning hole. Then, the positioning element 1 and the rotating element 2 are placed above the infusion port seat. The operator presses the positioning element 1 and the rotating element 2 with their index finger and thumb respectively, so that the positioning element 1 and the rotating element 2 position the infusion port seat. Simultaneously, the index finger and thumb press against the positioning element 1 and the rotating element 2 respectively. The contact position between component 1 and rotating component 2 is far from the positioning hole. When the infusion port needs to be pulled out of the body, the positioning hole needs to be fitted onto the infusion port; or when the infusion port needs to be inserted into the infusion port seat, the infusion port needs to be passed through the positioning hole first. Since there is a certain distance between the positioning hole and the index finger and thumb, the infusion port can avoid pricking the index finger or thumb. This solves the technical problem in the prior art where the infusion port pricking the index finger or thumb when inserting or removing the infusion port seat.

[0029] As an optional implementation, the positioning member 1 is provided with a receiving groove 12 inside. The opening side of the receiving groove 12 is located on the inner sidewall of the positioning member 1, that is, the opening side of the receiving groove 12 and the first positioning notch 11 are on the same side of the positioning member 1. The rotating member 2 can rotate into the receiving groove 12 to facilitate the rotation of the rotating member 2 and the positioning member 1. The connecting end of the rotating member 2 is located in the receiving groove 12.

[0030] As an optional implementation, the positioning member 1 is provided with a positioning handle 13. The positioning handle 13 is for easy hooking with the index finger or thumb, so that the operator can rotate the positioning member 1 and the rotating member 2 with one hand, and also for the operator to apply pressure to the infusion port seat through the positioning member 1, thereby preventing the infusion port seat from moving. There is a gap between the positioning handle 13 and the first positioning notch 11. This gap is to ensure that there is a certain distance between the index finger or thumb and the first positioning notch 11, and further ensure that there is a certain distance between the index finger or thumb and the infusion port needle, thereby preventing the infusion port needle from puncturing the index finger or thumb.

[0031] As an optional implementation, the positioning handle 13 is located at the free end of the positioning member 1, and the first positioning notch 11 is located in the middle region of the positioning member 1 and away from the free end of the positioning member 1.

[0032] As an optional implementation, the rotating part 2 is provided with a fixed handle 22. The fixed handle 22 is for easy hooking with the index finger or thumb, so that the operator can rotate the positioning part 1 and the rotating part 2 with one hand, and also for the operator to apply pressure to the infusion port seat through the rotating part 2, thereby preventing the infusion port seat from moving. There is a gap between the fixed handle 22 and the second positioning notch 21. This gap is to ensure that there is a certain distance between the index finger or thumb and the second positioning notch 21, and further ensure that there is a certain distance between the index finger or thumb and the infusion needle, thereby preventing the infusion needle from puncturing the index finger or thumb.

[0033] As an optional implementation, the fixed handle 22 is located at the free end of the rotating member 2, and the second positioning notch 21 is located in the middle region of the rotating member 2 and away from the free end of the rotating member 2.

[0034] As an optional implementation, the inner wall of the positioning member 1 is provided with a first inclined structure 14. The inner wall of the rotating member 2 is provided with a second inclined structure 23. When the infusion port is withdrawn from the body, the end of the infusion port is close to the skin. In order for the first positioning notch 11 and the second positioning notch 21 to fit over the needle of the infusion port, when the positioning member 1 and the rotating member 2 are closed, the tip of the first inclined structure 14 or / and the second inclined structure 23 will first extend between the end of the infusion port and the skin, thereby causing the positioning member 1 and the rotating member 2 to enter between the end of the infusion port and the skin, so that the first positioning notch 11 and the second positioning notch 21 can fit over the needle of the infusion port.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
