Abstract

The utility model relates to a medical apparatus which belongs to the technical field of a medical apparatus structure. An injector is composed of a needle tube 1, an injection bottle 2 and a connecting tube 3 which is arranged between the needle tube 1 and the injection bottle 2 and is also provided with a pressure regulator 4; the injector is characterized in that the periphery of the needle tube 1 is provided with a needle sleeve 5. Due to the needle sleeve is additionally arranged at the outside of the needle tube of the prior injector, the injector can overcome diverse defects existing in the prior medical injector efficiently, is safe and convenient to operate, can not only prevent accidental needle deviation, but also relieve discomfort generated on a human body by medicine solution flow column impact force, thereby the adverse reaction generated by direct contact of a needle head and a vessel wall is avoided, and pains generated on a patient during injection is reduced.

Description

Syringe

One, technical field

This utility model relates to a kind of medical apparatus and instruments syringe, belongs to technical field of medical appliance structures.

Two, background technology

At present; our existing injector for medical purpose in use, syringe needle is after being pushed into human vas, because the conventional injector syringe needle mostly is a metal material; be easy to generate untoward reaction owing to the Long contact time blood vessel wall in the injection process; syringe needle directly contacts with blood vessel in human vas, and through the situation of regular meeting's appearance scuffing blood vessel wall, phenomenon also may take the needle when serious; continuously in the injection process; the people is when activity, and syringe needle rotates blood vessel easily, causes patient's misery more.

Three, summary of the invention

The purpose of this utility model is to provide a kind of easy-to-operate, prevents that accident from taking the needle, and abirritant liquid stream column impact power is to the discomfort that human body produces, and avoids the direct syringe that contacts of syringe needle and blood vessel wall.

Syringe of the present utility model comprises needle tubing 1, and infusion bottle 2, and the connection tube 3 between needle tubing 1 and the infusion bottle 2 are established pressure regulator 4 on the connection tube 3, and special character is to be provided with a needle guard 5 in the periphery of needle tubing 1;

Needle guard 5 is selected for use the blood of human body nonhazardous and is not had the pliability of any negative interaction thin thin flexible pipe suitable with blood vessel, and needle guard 5 front end bevel angles are consistent with syringe needle 6 bevel angles of needle tubing 1, and both are used, and reach the purpose that is easy to inject with this.

This utility model syringe, employing adds the method for needle guard in the outside of original syringe needle tube, can effectively solve all deficiencies that existing injector for medical purpose exists, easy-to-operate, can either prevent that accident from taking the needle, the discomfort that again can abirritant liquid stream column impact power human body be produced, the untoward reaction of avoiding syringe needle to produce with direct contact of blood vessel wall has reduced the misery of patient's generation when injection.

Five, the specific embodiment

Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.

Embodiment 1

The syringe of present embodiment comprises needle tubing 1 with reference to figure 1,2, and infusion bottle 2, and the connection tube 3 between needle tubing 1 and the infusion bottle 2 also are provided with pressure regulator 4 on the connection tube 3, is provided with a needle guard that fits tightly with it 5 in the periphery of needle tubing 1; Described needle guard 5 is selected for use the blood of human body nonhazardous and is not had the pliability of any negative interaction thin thin flexible pipe suitable with blood vessel; Described needle guard 5 front end bevel angles are consistent with syringe needle 6 bevel angles of needle tubing 1, and both are used, and reach the purpose that is easy to inject with this.

During injection; the syringe needle of needle tubing 1 is exposed slightly; the needle tubing 1 that will have needle guard 5 again penetrates in the human vas; this moment is with needle tubing 1 post-tensioning slightly; the syringe needle position is entered in the needle guard 5; thereby effectively avoided metal needle tubing 1 to contact, reached protection human vas wall and do not injected the purpose that produces untoward reaction, thereby reduce the misery that patient produces when injection with the direct of blood vessel of human body.

The syringe of present embodiment, employing adds the method for needle guard in the outside of original syringe needle tube, can effectively solve all deficiencies that existing injector for medical purpose exists, easy-to-operate, can either prevent that accident from taking the needle, the discomfort that again can abirritant liquid stream column impact power human body be produced, the untoward reaction of avoiding syringe needle to produce with direct contact of blood vessel wall has reduced the misery of patient's generation when injection.

Claims

1, syringe, comprise needle tubing (1), infusion bottle (2), and the connection tube (3) between needle tubing (1) and the infusion bottle (2), also be provided with pressure regulator (4) on the connection tube (3), be characterised in that the periphery at needle tubing (1) is provided with a needle guard that fits tightly with it (5).

2, according to the described syringe of claim 1, it is characterized in that needle guard (5) selects for use the blood of human body nonhazardous and do not have the pliability of any negative interaction thin thin flexible pipe suitable with blood vessel, needle guard (5) front end bevel angle is consistent with syringe needle (6) bevel angle of needle tubing (1).
