Anti-stabbing blood taking needle

Abstract

The invention relates to the technical field of medical instruments, in particular to an anti-stabbing blood taking needle. The cover body is of a bent structure and is matched with the side grooves. When an operator takes down the cover body, the needle head can be exposed for blood sampling in a mode of bending towards the side part. In the process of taking down the cover body, the hand of an operator does not exceed the needle head and is always located behind the needle head, and therefore the situation that the needle head stabs the operator can be effectively avoided. The cover body is provided with the propelling device and a corresponding locking mechanism, so that the cover body can be always sleeved on the outer side of the needle rod when the cover body is not used, and a good protection effect is achieved; after use, locking can be released by pushing the pushing piece, and the purpose of taking down the cover body is achieved. After use, the cover body can be reset, and the needle rod is stored in the cover body again.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an anti-puncture blood collection needle. Background Art

[0002] A lancet is a commonly used blood collection device in hospitals and blood banks. Existing lancets typically consist of a needle, a flexible tube, a needle holder, and a needle shield. These lancets pose a risk of puncture injuries to healthcare workers during the blood collection process. This is because the needle shield fits over the needle, requiring the hand to move beyond the needle tip to remove it. Consequently, if the operator loses focus or is distracted by an external object pulling on their arm, the needle tip can cause a sticking injury. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above problems and provide a puncture-proof blood collection needle. To achieve the above purpose, the present invention adopts the following technical solutions:

[0004] A puncture-proof blood collection needle comprises a needle, a blood transfusion hose and a needle seat, wherein the two ends of the blood transfusion hose are respectively connected to the needle and the needle seat, the needle comprises a handle, a wing plate and a needle rod, the needle rod is arranged at the front end of the handle, the wing plate is arranged at one side of the handle, the needle is provided with a protective cover, the protective cover comprises a fixing seat, a cover body and a propulsion member, the fixing seat is fixed to the front end of the needle handle, the propulsion member slides along the fixing seat, the cover body is provided with a slot on one side, the cover body and the propulsion member are connected by a connecting portion and can be bent along the connecting portion;

[0005] When the pushing member is close to one end of the wing plate, the bottom of the cover body is sleeved on the fixed seat, and the end of the slot does not exceed the end of the needle rod, completing the locking of the cover body and accommodating the needle rod inside; after pushing the pushing member, the bottom of the cover body is separated from the fixed seat and bent along the connecting part, and the needle rod is laterally out of the cover body from the slot.

[0006] As an improvement, the handle is provided with an annular groove near the front end, and the fixing seat is provided with a protrusion that cooperates with the groove;

[0007] A sliding groove is provided on the side of the fixing seat.

[0008] As an improvement, a sliding block cooperating with the slide groove is provided at the bottom of the pushing member, and the pushing member slides along the slide groove under the guidance of the slide groove.

[0009] As an improvement, the propulsion member is a cylindrical structure, which is sleeved on the fixed seat from the outside, and a block is provided on one side of the propulsion member to limit its sliding distance;

[0010] The pushing member is provided with a guide sliding block at a position corresponding to the sliding groove.

[0011] As an improvement, a fixing bracket for fixing the bent cover body is provided on the top of the propulsion member.

[0012] As an improvement, the top of the fixing bracket is provided with adhesive and release paper, and the cover body is fixed to the fixing bracket by adhesive after being bent.

[0013] The advantages of the present invention are:

[0014] 1. The cover of this invention features a foldable structure with side slots. When removing the cover, the operator can bend it sideways to expose the needle for blood collection. During the removal process, the operator's hand remains behind the needle, effectively preventing needlestick injuries.

[0015] 2. The cover of this invention is equipped with a pusher and a corresponding locking mechanism. When not in use, the cover can be kept on the outside of the needle rod, providing good protection. After use, the pusher can be pushed to release the lock and remove the cover. After use, the cover can be reset to store the needle rod inside the cover again.

[0016] 3. The present invention is easy to use, has low production cost, and can be widely used in various hospitals and blood stations. BRIEF DESCRIPTION OF THE DRAWINGS
