Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of exhaustion syringe with oxygen supply, attraction and adjustable length.
Background technology
Syringe is a kind of utensil conventional in medical apparatus and instruments, syringe common at present comprises syringe needle, syringe and needle handle three parts are formed, it is simple that it has structure, advantage easy to use, but existing syringe great majority are all adopt to overlook injection, during injection, needle tip down, be applicable to during the disease of this mode for some routines, but sometimes need to look up injection, particularly animal carries out drug injection, during injection, needle tip upward, this time, the front end of injector syringe just there will be gas storehouse, this mode gas injected in gas storehouse is easily injected in body or in other animal bodies, cause great potential safety hazard.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of exhaustion syringe, and this exhaustion syringe is provided with liquid supply device by the front end at injector syringe, and liquid can fill gas storehouse, before the injection gas storehouse is exhausted, reaches the effect of safety injection.
In order to solve the problems of the technologies described above, a kind of exhaustion syringe of this utility model, the syringe needle comprising syringe, needle handle, needle holder and be arranged in needle holder, described needle holder is provided with fluid infusion hole, and described fluid infusion hole is connected with liquid supply device.
Further, described fluid infusion hole is arranged on the end face of needle holder, and described liquid supply device comprises the liquid supplementation pipe be connected with fluid infusion hole and the fluid infusion bag and the fluid infusion bottle that are connected to the liquid supplementation pipe other end.
Further, described liquid supplementation pipe is set to flexible pipe, and described flexible pipe is provided with flow control switch.
Further, the front end near needle holder in described syringe is provided with permeable membrane, and syringe is separated into gas storehouse and medicinal liquid storehouse or medicine storehouse by described permeable membrane, and described fluid infusion hole is communicated with described gas storehouse.
Further, the end of described needle handle is provided with the spine for breaking through permeable membrane.
Further, the front end near needle holder in described syringe is provided with waterproof ventilated membrane, and syringe is separated into gas storehouse and medicinal liquid storehouse by described waterproof ventilated membrane, and described fluid infusion hole is communicated with described gas storehouse.
Further, the end of described needle handle is provided with the spine for breaking through waterproof ventilated membrane.
The beneficial effects of the utility model are:
This utility model exhaustion syringe is provided with liquid supply device by the front end at injector syringe, and liquid can fill gas storehouse, is exhausted before the injection to gas storehouse, reaches the effect of safety injection.

Fig. 1 is the structural representation of this utility model exhaustion syringe;
Reference numeral: 1-syringe; 2-needle handle; 3-needle holder; 4-syringe needle; 5-fluid infusion hole; 6-fluid infusion bag; 7-switch; 8-medicinal liquid storehouse; 9-gas storehouse; 10-permeable membrane.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, utility model is described in further detail.
Be illustrated in figure 1 the structural representation of this utility model exhaustion syringe, a kind of exhaustion syringe of this utility model, the syringe needle 4 comprising syringe 1, needle handle 2, needle holder 3 and be arranged in needle holder 3, described needle holder 3 is provided with fluid infusion hole 5, and described fluid infusion hole 5 is connected with liquid supply device.
The present embodiment is provided with liquid supply device by the front end at injector syringe, in looking up and injecting, the injection storehouse in gas storehouse 9, syringe needle 4 can be filled by the liquid in liquid supply device, before the injection gas storehouse 9 and injection storehouse are exhausted, just drug injection can be carried out by promoting needle handle 2 after liquid comes up from syringe needle 4 end, this fluid infusion mainly adopts mends liquid of glucose or the solvent harmless to humans and animals health, this structure before the injection, be exhausted, the effect of safety injection can be reached
Further, preferred described fluid infusion hole 5 is arranged on the end face of needle holder 3, described liquid supply device comprises the liquid supplementation pipe be connected with fluid infusion hole 5 and the fluid infusion bag 6 and the fluid infusion bottle that are connected to the liquid supplementation pipe other end, preferred described liquid supplementation pipe is set to flexible pipe, described flexible pipe is provided with flow control switch 7, and the present embodiment is controlled by flow control switch 7, fluid infusion situation can be controlled, after fluid infusion completes, closing switch 7, when can avoid injecting, medicine enters fluid infusion bag 6 and fluid infusion bottle.
Further, in preferred described syringe 1, the front end of needle holder 3 is provided with permeable membrane 10, syringe is separated into gentle storehouse 9, medicinal liquid storehouse 8 by described permeable membrane 10, described fluid infusion hole 5 is communicated with described gas storehouse 9, the present embodiment by advance by medicament storage in medicinal liquid storehouse 8, liquid medicine contamination can be avoided, by being arranged on permeable membrane 10, supplementary liquid of glucose is filled up or other liquid can enter in medicinal liquid storehouse 8 and medicament mixed by permeable membrane 10 in gas storehouse, evenly rock rear formation medicinal liquid, the air in medicinal liquid storehouse 8 can be got rid of by liquid of glucose or other liquid, fill up supplementary liquid of glucose or other liquid in gas storehouse after, start injection, by promoting needle handle 2, permeable membrane 10 can be broken through, medicine and liquid of glucose are mixed entered in human body by syringe needle.
