Abstract
The utility model discloses a syringe needle head which comprises a needle head body and a needle head seat which is fixedly connected with the lower end of the needle head body. The needle head seat is connected with an anti-prick sleeve through a connecting strap. Block slits are reserved in the side face of the anti-prick, wherein the block slits are used for containing the needle head body and are matched with the needle head body in a locking mode. A plurality of locking pieces are arranged inside the anti-prick sleeve along the radial direction. The block slits are arranged on the locking pieces. Due to the fact that the anti-prick sleeve which can be laterally separated and fastened along the needle head body is used, the injection can be carried out after the anti-prick sleeve is separated in the process of injection. The anti-prick sleeve can be pulled to be fastened to the needle head body again from the side face of the anti-prick sleeve after the injection, so that possible prick which is caused by the touch between the hands of medical works and the needle tip of the needle head body is avoided, and therefore using safety is higher.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to the syringe needle structure technology.
Background technology
The medical worker carries out in the intramuscular injection process for patient, injects the complete event that needle sting easily occurs when extracting syringe needle, easily causes infecting.
Summary of the invention
The purpose of this utility model is: the deficiency for prior art exists, provide a kind of simple in structure, and can prevent effectively that the medical worker is by the syringe needle header structure of needle sting.
For realizing the purpose of this utility model, be achieved by the following technical solutions: a kind of syringe needle, the needle holder that includes needle head body and be fixedly connected on the needle head body lower end, be connected with an anti-tie cover by brace on needle holder, anti-tie cover side is provided with the card seam that holds needle head body and coordinate engaging with needle head body.
As preferred version: radially be provided with a plurality of engaging sheets in described anti-tie cover, described card seams on the engaging sheet.
As preferred version: the card seam on described engaging sheet and the needle tip interference fit of needle head body.
As preferred version: described anti-tie be enclosed within brace do not stress under state and the angle between needle head body greater than 90 °.
Compared with prior art, the beneficial effects of the utility model are: owing to having used the anti-tie cover that can break into two with one's hands, fasten along the needle head body side direction, can inject break anti-tie cover into two with one's hands when injection after, pull anti-tie cover after injection is completed again fastens to needle head body and gets final product from anti-tie cover side, avoided like this medical personnel's hand to contact and issuable stabbing with the needle head body needle point, safety in utilization is higher.

The specific embodiment
The below makes a detailed explanation the specific embodiment of the present utility model with reference to the accompanying drawings.
How shown in Figure 2 according to Fig. 1, the described a kind of syringe needle of the present embodiment, the needle holder 21 that includes needle head body 2 and be fixedly connected on needle head body 2 lower ends, needle head body 2 is received in the outlet of syringe 1 by needle holder 21 covers, be connected with an anti-tie cover 22 by brace 23 on needle holder 21, anti-tie cover 22 sides are provided with the card seam 222 that holds needle head body 2 and coordinate engaging with needle head body 2.
Radially be provided with a plurality of engaging sheets 221 in described anti-tie cover 22, described card seam 222 is located on engaging sheet 221.Described engaging sheet 221 is thin slice, easily produces deformation, so that fasten with needle head body 2.
Described anti-tie cover 22 under brace does not stress state and the angle between needle head body 2 greater than 90 °.Can guarantee that so anti-tie cover 22 can not stop needle head body 2 when injecting.
The diameter of the width of described brace 23 and needle holder 21 is suitable, can guarantee that so anti-tie cover 22 anti-tie cover 22 in the needle head body 2 fastening processes does not produce laterally offset.
Can inject after breaking anti-tie cover 22 into two with one's hands in when injection, pull anti-tie cover 22 after injection is completed from anti-tie cover 22 sides and again fasten to needle head body 2 and get final product.
