Abstract

The utility model relates to a medicinal liquor intravenous infusion device by using bolus, which comprises: a medicinal liquor intravenous infusion device. The medicinal liquor intravenous infusion device comprises: a 6:100 locking joint (1), a injector (2) which is used to place the medicinal liquor and a pushing liquid mechanism (3) behind the injector (2); also comprises: a shell (4) which is equipped fixedly at the end of the injector (2) and on the pushing liquid mechanism (3); the shell (4) comprises: a spring (41) which touch the end and pushing liquid mechanism (3), and a pushing locking-ring (2) which is installed at the combination between the spring (41) and the end of the pushing liquid mechanism (3).Characteristics: the bolus is suitable for the transfusion therapy in on and off or continuously; because the shape of the bolus is small relatively, the structure is simple, and the device is light, which can be provided to the patients in hospital fixedly or not, and the patients at home; meanwhile, the rod-like shape is easy to be seized in hands tightly by patients to take the injection with the portable medicine liquid.

Description

Adopt the venoclysis medicinal liquid device of injector

Technical field

This utility model relates to a kind of venoclysis medicinal liquid device, relates in particular to the injector in this venoclysis medicinal liquid device.

Background technology

In medical clinical vein transfusion medicinal liquid process, some special transfusions such as the low dose medicinal liquid of infusing at a slow speed needs to use mini-plant class apparatuses such as infusion pump.

Infusion pump commonly used at present generally adopts desktop electric control, though this kind equipment volume oneself through less, but inconvenient patient carries, or because of after using infusion pump, the scope that the patient can take action is subjected to bigger placing restrictions on, and the cost of equipment and cost of use are higher relatively.

If the scene does not have infusion pump, then can only adopt the mode of hand push, bring very big trouble for patient and medical personnel.

Summary of the invention

This utility model technical issues that need to address have provided a kind of venoclysis medicinal liquid device that adopts injector, are intended to solve above-mentioned defective.

In order to solve the problems of the technologies described above, this utility model is achieved through the following technical solutions:

This utility model comprises: venoclysis medicinal liquid device; Described venoclysis medicinal liquid device comprises: the 6:100 lock-on connection, push away liquid mechanism after placing the syringe of injection liquid and being placed in syringe; Also comprise: but a fixed in position is at syringe tail end and the housing that pushes away in the liquid mechanism; In housing, comprise: one with push away the spring that liquid mechanism tail end contacts, one revolves ring in spring and the thrust locking that pushes away liquid mechanism tail end contact position;

Compared with prior art, the beneficial effects of the utility model are: be applicable to the interrupted or successive low capacity infusion of therapeutic of infusion medicinal liquid at a slow speed, because the build of injector is less relatively, it is simple to connect structure, in light weight, the patient that can offer in fixing, in hospital fixing and the family uses; Simultaneously, bar-shaped profile can be fixed in positions such as patient's arm easily, carries out the medicinal liquid infusion and supply the patient to carry.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:

As seen from Figure 1: this utility model comprises: venoclysis medicinal liquid device; Described venoclysis medicinal liquid device comprises: 6:100 lock-on connection 1, push away liquid mechanism 3 after placing the syringe 2 of injection liquid and being placed in syringe 2; Also comprise: but a fixed in position is at syringe 2 tail ends and the housing 4 that pushes away in the liquid mechanism 3; In housing 4, comprise: one with push away 41, one on spring that liquid mechanism 3 tail ends contact and revolve ring 42 in spring 41 and the thrust locking that pushes away liquid mechanism 3 tail end contact positions;

Can also add disposable use injection flow control tube 5 in the exit of 6:100 lock-on connection 1;

As seen from Figure 2: the locking of described thrust revolve ring 42 comprise one be exposed at housing 4 outer revolving 421, one on ring and revolve that ring is 421 that link to each other, an end contacts with spring 41, the other end and housing 4 inboards can connect airtight and touch or discerptible stopper 422;

By Fig. 3, Fig. 4 A, Fig. 4 B as seen: housing is inboard gapped with stopper, and the slip non-locking pushes away liquid mechanism and infuses under spring action; Housing is inboard not to have the gap with stopper, and slide lock stops transfusion.

This utility model adds a reusable injector and a disposable injection flow control tube on original injection device, can be applicable to the syringe of 10ml, 30ml and 50ml respectively.The injecting liquid drug speed of injecting realizes that by the flow control tube of apolegamy flow control tube is again with the use that connects and prolong adapter simultaneously.For making syringe behind the perfusion solution after being loaded into injection device, the lockable acting force of the spring stops fluid injection, therefore can install a thrust locking additional and revolve ring on injection device, revolves ring by rotation and can lock spring, and eliminated the output that the power of injecting is transmitted.

Claims

1. a venoclysis medicinal liquid device that adopts injector comprises: venoclysis medicinal liquid device; Described venoclysis medicinal liquid device comprises: 6:100 lock-on connection (1), push away liquid mechanism (3) after placing the syringe (2) of injection liquid and being placed in syringe (2); It is characterized in that: also comprise: but a fixed in position is at syringe (2) tail end and the housing (4) that pushes away in the liquid mechanism (3); In housing (4), comprise: one with push away the spring (41) that liquid mechanism (3) tail end contacts, one revolves ring (42) in spring (41) and the thrust locking that pushes away liquid mechanism (3) tail end contact position.

2. the venoclysis medicinal liquid device of employing injector according to claim 1 is characterized in that: can also add disposable use injection flow control tube (5) in the exit of 6:100 lock-on connection (1).
