Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of medical devices, and particularly relates to a needle-stick-prevention infusion device needle. BACKGROUND
[0002] The infusion device needle is a key component of a medical infusion device, which is usually composed of a needle tip, a needle tube and a connecting part, is used for puncturing the skin and blood vessels of a patient, establishing an infusion channel, and enabling medicine to enter the patient's body smoothly, and is an important tool for realizing medicine delivery in clinical treatment.
[0003] In traditional medical practice, the traditional infusion device needle has a serious safety hazard after completing the infusion task. After the medical staff pulls out the needle from the patient's body, the used needle is directly exposed due to the lack of an effective protection mechanism. In the subsequent processing process, whether the medical staff classifies and disposes the needle or the patient accidentally touches the needle, the sharp needle tip is extremely likely to cause needle stick injuries.
[0004] Such needle stick injuries not only cause physical pain to the injured person, but also can cause serious health problems. SUMMARY
[0005] In order to solve the above problems, the application provides a needle-stick-prevention infusion device needle.
[0006] The technical scheme adopted by the application is as follows: the application provides a needle-stick-prevention infusion device needle, which comprises an infusion shell, a sliding infusion inner tube in the infusion shell, a needle head connected to one end of the infusion inner tube, and the infusion inner tube rotatingly arranged in the infusion shell.
[0007] Further, an insertion piece is fixedly connected to the outer side wall of the infusion inner tube.
[0008] Further, a first clamping groove is formed in the side wall of the infusion shell, a sliding groove is formed in the side wall of the infusion shell, a second clamping groove is formed in the side wall of the infusion shell, and the first clamping groove and the second clamping groove are connected through the sliding groove.
[0009] Further, a needle tip is arranged at the top end of the needle head.
[0010] Further, the sliding groove is used for moving the insertion piece between the first clamping groove and the second clamping groove.
[0011] Further, the other end of the infusion inner tube is fixedly sleeved with an inner sleeve at one end of a needle tube, and the other end of the needle tube is provided with a needle seat.
[0012] The application has the following beneficial effects by adopting the above structure: (1) After the infusion is completed, the infusion inner tube is rotated by moving the insert piece from the first clamping slot to the sliding slot, then the insert piece is moved downward to the lower end of the sliding slot to make the needle retract into the infusion shell, and finally the insert piece is moved to the second clamping slot to be fixed. This series of operations ensures that the needle can be safely stored in the infusion shell after use, avoiding the risk of needle stick injury to medical staff or patients when handling used needles, greatly reducing the risk of blood-borne disease infection caused by needle stick injury.
[0013] (2) The function is realized by the cooperation of the insert piece, the clamping slot and the sliding slot, the overall structure is compact, no additional components are added, the production and assembly of the infusion device are facilitated, and the size of the infusion device is also reduced, facilitating carrying and storage.
[0014] (3) The mechanical cooperation of the insert piece, the clamping slot and the sliding slot is used to control the action of the needle, and such mechanical structure is relatively stable and reliable, and is not prone to failure. BRIEF DESCRIPTION OF DRAWINGS
