Abstract
The utility model discloses a kind of not damaged slip-off preventing puncture needle, it is shaped with syringe needle in the front end of needle body, the front end of syringe needle is provided with needle point, the rear side of needle point is provided with puncture portion, the rear side in puncture portion is provided with guide part, the rear side of guide part is provided with leakage hole, the opening part of both sides, puncture portion is provided with lower sword limit, the opening part of guide part both sides is provided with sword limit, the rear side of leakage hole is provided with crescent dull face, this utility model structure is simple, design is unique, due to the streamlined design in upper and lower sword limit and sword face, its smooth surface, clean as mirror, can effectively warrantor soma do not pulled and be come off after making needle body enter human body, the effective transfusion injection safety having ensured human body.
Description
Technical field
This utility model relates to a kind of medical instruments, is specifically a kind of not damaged slip-off preventing puncture needle.
Background technology
In clinical medicine application, intramuscular injection and intravenous drip suppress the state of an illness, save the Major medical approach of life, the puncture needle sold in the market and use, its planform is all inclined-plane pin, the aufbauprinciple of inclined-plane pin is on hollow cylinder body, be shaped with an inclined-plane, beveled top end outside is in acute angle, the inner side of inclined-plane rear cylindrical body is a crescent sword face, inclined-plane forward angles is less, and needle point is sharper, and crescent sword face is also sharper, crescent sword face is sharper, more easily makes tissue come off when thrusting human body.Simultaneously because production firm is when processing, only lay particular stress on the sharp-pointed and sharp of syringe needle, and have ignored reparation and the polishing in sword face, syringe needle is caused to leave tool marks in the machining of lathe, burr or chamfering, tool marks on these basil inclined-planes, burr, chamfering and crescent sword face are when entry needle enters human body, because tissue clamp-ons the hollow part of syringe needle under elastic force effect, cause the sword face basil to the cutting of tissue and friction, thus cause coming off of tissue, come off the tissue microgranule that falls along with in medicinal liquid intravasation, form the blood capillary of foreign matters from being blocked human body, serious harm and impact are caused safely on the health and lives of human body.
Summary of the invention
The purpose of this utility model is just to provide a kind of not damaged without the puncture needle come off, the harm caused human body during to solve the injection of existing puncture needle, the life security of protection patient.
Scheme of the present utility model comprises needle body and syringe needle, needle body is a round tubular body, the front end of needle body is shaped with syringe needle, syringe needle is made up of needle point, puncture portion, guide part and leakage hole, its construction features is provided with needle point in the front end of syringe needle, the rear side of needle point is provided with puncture portion, and the rear side in puncture portion is provided with guide part, and the rear side of guide part is provided with leakage hole.Described needle point, puncture portion and guide part are the oblique sections be equipped with at the front opening of needle body, and the opening part of both sides, puncture portion is provided with lower sword limit, and the opening part of guide part both sides is provided with sword limit, and the rear side of leakage hole is provided with crescent dull face.Described lower sword limit and upper sword limit are streamlined design, and the edge of upper and lower sword limit and crescent dull face is processed as smooth surface through chamfering fine-grinding and polishing, and the inside and outside tube wall of described needle body is made as smooth surfaces externally and internally through polish.
The utility model has the advantages that structure is simple, design is unique, due to upper and lower sword limit and sword face streamlined design and through fine-grinding and polishing process, its smooth surface, clean as mirror, can effectively warrantor soma not be damaged and prevent from coming off after making needle body enter human body, effectively ensure the transfusion injection safety of human body.
Be described in further detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is puncture needle structure schematic diagram;
Fig. 2 is piercing needle structure enlarged diagram.
Detailed description of the invention
The front end of the needle body 1 shown in Fig. 1-2 is provided with syringe needle, the front end of syringe needle is provided with needle point 6, the rear side of needle point is provided with puncture portion 5, the rear side in puncture portion is provided with guide part 4, the rear side of guide part is provided with leakage hole 3, the oblique section that described needle point 6, puncture portion 5 and guide part 4 are equipped with for needle body front opening, and the opening part of both sides, puncture portion is provided with lower sword limit 7, the opening part of guide part both sides is provided with sword limit 8, and the rear side of leakage hole is provided with crescent dull face 2.Described lower sword limit and upper sword limit are streamlined design, and upper and lower sword limit and crescent dull face are smooth surface, and the inside and outside tube wall of needle body is smooth surfaces externally and internally.Described lower sword limit 7 is puncture sword limits of vertical cut from top to bottom on the tube wall of puncture portion section, and this section is made downward-sloping puncture sword limit, make syringe needle sharp, resistance is little.Described upper sword limit is the guiding sword limit of horizontal cutting on the tube wall of guide section, so that guide needle body to enter human body with puncture portion.
