Description

Novel side opening syringe needle

Technical Field

The utility model relates to a medical treatment pjncture needle specifically is a novel side opening syringe needle.

Background

The intravenous infusion is one of the important measures for the clinical rescue and treatment of patients in hospitals, and the most common disposable intravenous infusion injection needle at present adopts the method that an infusion tube is sleeved on a tubular injection needle, when in use, a needle head is pricked into the blood vessel of a patient, and medicines enter the blood vessel through the infusion tube and the infusion needle.

The injection needle for infusion or the puncture needle is usually disposable, and this is to prevent cross infection. The discarded needles are used as medical waste for centralized treatment. The injection needle that usually discards exposes in the garbage bin, takes place the puncture accident easily when retrieving the arrangement, has the infection risk. According to the report of the world health organization, the number of patients suffering from needle damage and infected with hepatitis B is as many as 800 to 1600 thousands, 200 to 450 thousands and 7 to 15 thousands all over the world, so that the problem of disposing of the waste needle can not be ignored and needs to be paid sufficient attention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a novel side-hole injection needle includes a needle base 1, a sheath 2 and a needle head 3, wherein both sides of the needle base 1 are provided with arc-shaped grips 11, and the grips 11 facilitate installation or detachment of the injection needle; the needle head 3 is fixed on the needle seat 1, the side surface of the bottom of the needle head 3 is provided with a plurality of side holes 31, the side holes 31 are arranged along the axial direction of the needle head 3, and the side holes 31 are arranged at the end head of the needle head 3, so that the side holes 31 are still left in the vein when the vein passes through too much, the puncture failure is avoided, and the puncture success rate is improved;

the sheath 2 comprises a plurality of groups of elastic sheets 22 which are symmetrically arranged in an annular array, the bottoms of the elastic sheets 22 are integrally connected, the elastic sheets 22 are all bent towards the circle center of the sheath 2, a rubber layer 23 is fixedly adhered to the tops of the elastic sheets 22, a valve 21 made of rubber is fixedly adhered to the bottom of the sheath 2, and the valve 21 is composed of a plurality of sectors which are as large as one another.

As shown in fig. 4, a raised snap ring 24 is further arranged at the top of the elastic sheet 22, a groove for accommodating the elastic sheet 22 is arranged at the bottom of the needle seat 2, a clamping groove matched with the snap ring 24 is arranged in the groove, the sheath 2 passes from the bottom of the needle 3 and moves to the needle seat 1 during assembly, the elastic sheet 22 is gradually bent and expands outwards and then is inserted into the groove, the clamping groove is clamped by the snap ring 24 to fix the sheath 2, when the injection needle is discarded after use, the sheath 2 is pulled out from the needle seat 1 and moves to the bottom of the needle 3, the elastic sheet 22 is in an inward recovery state and is pressed on the needle 3 after moving out of the groove, friction between the rubber layer 23 in the elastic sheet 22 and the surface of the needle 3 is increased, after the tip of the needle 3 is moved, the end face of the sheath 2 is sealed by the valve 21, so that the tip of the needle 3 is covered in the needle seat without being exposed outside.
