A patient can conveniently perform muscle injection by the medical self injection device with the structure, and the needle can be retracted after use, so the medical pollution is prevented.
Description
Technical field
This utility model relates to injector for medical purpose technology, particularly, relates to a kind of medical self-injection device.
Background technology
At present, along with improving constantly of the medical level of countries in the world, people have had new requirement to the health of medical supplies and convenient degree.For a long time, the infection in medical procedure constantly occurs, no matter be medical personnel or patient, its route of infection are direct contagion or indirect infection nothing more than, and wherein, indirect infection major part is that the clean or improper use of medical apparatus and instruments causes.Take syringe as example: it is one of medical apparatus and instruments that clinical middle frequency of utilization is higher, is also the apparatus directly contacting with patient.The syringe of traditional form needs to carry out disinfection with the position that alcohol swab first need be injected patient before using, and after injection, with medical cotton ball, injection site is stopped blooding again.But, during operation above-mentioned steps, often have carelessness.For example, after injection in the process of hemostasis, also there will be misoperation to cause hemostasis not thoroughly or the situation infecting.And, sickness rate raising along with the frequent injectable drug disease of various needs, increasing needs of patients often carries out injection for curing, and existing normal injection syringe inconvenient patient carry out self-injection, need rush towards that hospital injects or by other people auxiliary injection, expend plenty of time and money, and very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of novel medical self-injection device, and this device facilitates patient to carry out self-intramuscular injection, and this device can carry a hemostasis disinfection plaster, convenient has injected afterwards to the injection port hemostasis that carries out disinfection, and protects from infection.
Self-injection apparatus structure that this utility model provides is simple, cost is low, be easy to produce in enormous quantities, and easy to use.
This utility model provides a kind of medical self-injection device; this device comprises syringe part and the supplemental cartridge partly coordinating with syringe; supplemental cartridge is enclosed within the top of syringe part to protect the syringe needle exposing; wherein the needle holder of syringe part front end is provided with external screw thread; for coordinating the female thread in supplemental cartridge, so that syringe part is closely linked together with supplemental cartridge.When two parts link together, syringe needle can expose outside supplemental cartridge to be injected to facilitate.Device of the present utility model only makes syringe needle expose predetermined length, therefore, can person easy to use completes easily self-injection and without any other people auxiliary, and does not worry that also can not cause syringe needle to thrust skin damages excessively deeply.
This utility model compared with prior art has following outstanding advantages:
1, this utility model cost is low, simple in structure, easy to use, is easy to produce in enormous quantities;
2, this utility model can be injected patient voluntarily, without rushing towards hospital, saves plenty of time and money, has greatly reduced patient infection and the probability improperly that stops blooding simultaneously;

The specific embodiment
Describe with reference to the accompanying drawings illustrative of the present utility model, non-limiting example in detail, to being further described according to injection device of the present utility model.
In embodiment of the present utility model; referring to Fig. 1-4; according to device of the present utility model, comprise two parts, comprise syringe part A and the supplemental cartridge B partly coordinating with syringe, supplemental cartridge B is connected to the top of described syringe part A to protect the syringe needle exposing.Syringe part A comprises rubber piston 3, needle holder 4, needle stand 5 and the syringe needle 6 of syringe cylinder 1, injection putter 2, push rod front end, and syringe needle 6 is fixed on needle stand 5, and needle stand 5 can embed in needle holder 4, closely links together with it.
Supplemental cartridge B is cylindric, comprises helmet 7, sheath 8 and keeps seat 9.Sheath 8 is hollow cylinder, and top is provided with roof 10, is provided with circular hole 11 on roof 10, and when supplemental cartridge and syringe partly link together, syringe needle 6 can expose by described circular hole 11, is convenient to self-injection; The bottom-open of sheath 8, and be provided with in the circle extending internally along 12.Keep seat 9 to be similarly cylindric, its top is provided with outward extending outer 13, and keep seat 9 to be embedded in sheath 8, and can in sheath 8, slide up and down, and interior along 12 and the setting of outer 13, make to keep seat can not skid off a bottom for sheath 8.Keep seat 9 bottoms to be provided with groove 14, groove 14 matches with needle holder 4, by needle holder 4 outer walls and arranging of groove 14 inwalls, both closely being linked together, and then supplemental cartridge B and syringe part A is closely linked together.Groove 14 is to keeping being provided with the duct 16 that syringe needle is passed through on the roof 15 of seat 9, when syringe part A and supplemental cartridge B link together, syringe needle 6 can passing hole channel 16 and circular hole 11 expose supplemental cartridge B.The interior spring 17 that arranges of sheath 8, one end of spring 17 connects the roof 10 of sheath 8, and one end connects the roof 15 that keeps seat 9 in addition, and syringe needle 6 is through spring 17.When injection, by sheath 8 roofs 10, overlay and on injection of skin position, make to keep seat 9 in the interior slip of sheath 8 and Compress Spring 17, now syringe needle exposes the skin that thrusts injection position, and while having injected, spring 17 stretches, and keeps 9 times cunnings of seat that syringe needle 6 is taken back.In addition, the top of sheath 8 arranges helmet 7, for the protection of syringe needle and prevent from polluting.In addition, arranging of described needle holder 4 outer walls and groove 14 inwalls can be buckle setting or internal and external threads setting.
While using said apparatus, by syringe part A and supplemental cartridge B are linked together and make syringe needle expose suitable length.Therefore,, when injecting, can directly carry out self-intramuscular injection by hand-held device of the present utility model, and it is excessively dark not worry that syringe needle bending or syringe needle penetrate muscle.In addition, on the outer wall of described sheath 8, portion of the handle can be set.
Although exemplary embodiments of the present utility model is illustrated, but obviously it will be appreciated by those skilled in the art that, in the situation that not deviating from spirit of the present utility model and principle, can change, its scope claims with and equivalent in limit.
