Abstract
The utility model discloses a combined injector. The front part of the combined injector is provided with a compression liner which is fixed to the lower part of a cap plug, the upper part of the cap plug is provided with a needle connecting column, and a needle head is connected to the needle connecting column. The outside of the cap plug is provided with an elastic clamping hook, a shielding head on the outside of a cylinder is hooked by the elastic clamping hook, the cap plug is fixed to one end of the cylinder whose the other end is provided with a piston, and the rear part of the combined injector is composed of the cylinder and the piston. One device used for dual purposes is implemented, and both vein blood samples can be collected and intramuscular injection can be processed. Meanwhile, cross-contamination is avoided, materials are saved, cost is reduced, and a patient's economic burden is lightened.
Description
This utility model relates to a kind of knockdown, can gather the syringe that venous samples can again can liquid medicine injection on medical.
Various big hospital has all been promoted the use of disposable blood taking device and disposable syringe at present, though avoided cross-contamination, the cost height, patient bears heavily, and the amount of waste disposal simultaneously is also bigger.
The purpose of this utility model is to provide a kind of simple in structure, combined and instant, syringe that cost is low.
This utility model is realized as follows: a compression gallbladder is arranged in the front portion of syringe, the compression gallbladder is fixed on the capping plug bottom, capping plug top has one to connect the pin post, syringe needle is connected and connects on the pin post, in the capping plug outside one elastic fastening hook is arranged, hook the retaining head in the cylinder outside, make capping plug be fixed on an end of cylinder by grab, the other end of cylinder is equipped with piston, and cylinder and piston constitute the rear portion of syringe.
Below in conjunction with accompanying drawing, this utility model is described.
Fig. 1 is an assembly drawing of the present utility model.
With reference to accompanying drawing, a compression gallbladder ［ 5 ］ is arranged in the front portion of syringe, the compression gallbladder is fixed on the cylinder of capping plug ［ 3 ］ bottom, capping plug top has a taper to connect pin post ［ 2 ］, and syringe needle ［ 1 ］ is connected and connects on the pin post ［ 2 ］, in capping plug ［ 3 ］ outside one elastic fastening hook ［ 4 ］ is arranged, hook the retaining head ［ 6 ］ in cylinder ［ 7 ］ outside by grab, make capping plug ［ 3 ］ be fixed on an end of cylinder, the other end of cylinder is equipped with piston ［ 8 ］, and cylinder ［ 7 ］ and piston ［ 8 ］ constitute the rear portion of syringe.
When gathering venous samples can, earlier piston ［ 8 ］ is pushed the top, with pack into the nozzle of cylinder ［ 7 ］ of syringe front portion, elastic fastening hook ［ 4 ］ is hooked the retaining head ［ 6 ］ in cylinder ［ 7 ］ outside, anterior device is fixed, begin blood sampling after then syringe needle ［ 1 ］ being inserted vein, when being extracted into aequum, transfer to syringe needle ［ 1 ］, the disposable test tube of the anti-injection of blood sample is stand-by, remove anterior the destruction, stay the rear portion and continue to use.
When making injection, earlier piston ［ 8 ］ is pushed the top, with pack into the nozzle of cylinder ［ 7 ］ of anterior device, hook the retaining head ［ 6 ］ in cylinder ［ 7 ］ outside with elastic fastening hook ［ 4 ］, anterior device is fixed, then syringe needle ［ 1 ］ is inserted in the medicinal liquid bottle, when medicinal liquid is drawn into compression gallbladder ［ 5 ］ from the medicinal liquid bottle after, promote piston ［ 8 ］ venting air, inject then, after injection finishes the front portion is lost into wastebin, the rear portion still continues to use.
This utility model has realized that a device is dual-purpose, can gather the venous samples can specimen, can carry out intramuscular injection again, has also avoided cross-contamination simultaneously, has saved material, has reduced cost, has alleviated financial burden to patient.
