Preferably, the fixing bolt is of a telescopic structure.
Through above-mentioned technical scheme, can be according to the length adjustment protective sheath's of steel needle length.
Preferably, the puncture-preventing device comprises a rubber sleeve, a rubber plate is fixedly mounted on the surface of the rubber sleeve, a groove is formed in the surface of the rubber plate, and the groove is of an arc-shaped structure.
Through above-mentioned technical scheme, prevent that the syringe needle that exposes outside from accidentally injuring medical staff and the staff of collecting medical waste, avoid stabbing and infecting, the recess is facing to the needle point, avoids the needle point card again on the protective sheath when protecting the needle point.
Preferably, a fixed plate is fixedly mounted on one surface of the rubber plate, one end of the fixed plate is fixed to the protective sleeve in a hinged mode, and the other end of the fixed plate is fixed to the protective sleeve through a buckle.
Through above-mentioned technical scheme, the accessible promotes the syringe needle, utilizes thrust to push away the fixed plate, and the protective sheath can be opened, closed to the convenient to use syringe needle, is convenient for avoid the syringe needle to expose in the outside when abandoning.
Preferably, a protective layer is adhered to one surface of the fixing plate, and the protective layer is made of rubber.
Through the technical scheme, the medical staff is prevented from stabbing while the needle tip is protected.
The utility model discloses the beneficial effect who reaches is:
1. this disposable infusion syringe needle of improvement formula sets up and prevents stabbing the device, prevents to expose the staff that medical staff and collection medical waste were hurt by mistake to outer syringe needle, avoids stabbing and infects, and the recess is facing to the needle point, avoids the needle point card on the protective sheath again when protecting the needle point, and the accessible promotes the syringe needle, utilizes thrust to push away the fixed plate, and the use syringe needle of being convenient for can open, close the protective sheath, is convenient for to the use of syringe needle.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
In the drawings:
fig. 1 is a schematic structural diagram of the present invention.
As shown in the figure: 1. a needle head; 101. a fin; 2. a protective sleeve; 201. a fixing bolt; 202. a rubber sleeve; 203. a rubber plate; 204. a fixing plate; 205. and a protective layer.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1, an improved disposable infusion needle comprises a needle 1 and a protective sleeve 2, wherein a wing 101 is fixedly arranged on one surface of the needle 1, the wing 101 and the protective sleeve 2 are fixed through spiral threads, and a fixing bolt 201 is fixedly arranged on one surface of the protective sleeve 2;
further, the fixing bolt 201 is a telescopic structure.
The length of the protective sleeve can be adjusted according to the length of the steel needle.
The protective sleeve 2 is internally and fixedly provided with a puncture-proof device;
further, prevent stabbing device includes rubber sleeve 202, and rubber sleeve 202 fixed surface installs rubber slab 203, and a surface of rubber slab 203 is seted up flutedly, and the recess is the arc type structure.
The medical staff and the staff collecting medical waste are prevented from being accidentally injured by the exposed needle head, the infection caused by puncture is avoided, the groove faces the needle point, the needle point is protected, and meanwhile the needle point is prevented from being clamped on the protective sleeve 2.
Further, a fixing plate 204 is fixedly mounted on one surface of the rubber plate 203, one end of the fixing plate 204 is fixed to the protective sleeve 2 through a hinge, and the other end of the fixing plate 204 is fixed to the protective sleeve 2 through a buckle.
