Abstract

The utility model relates to a propeller for injection. Springs or rubber ribs are used for providing motive power, and the utility model is composed of a box body provided with a slot, wherein the box body is hollow, a shaft is erected on a side plate, and a transmission wheel, a power wind spring and a control gear are installed on the shaft on which a pressure spring is arranged; a screwing handle is used for rotating the wind spring to store energy, and accordingly, a base on the box body is driven to propel an injector to operate. The utility model has advantages of simplicity, reliability, adjustable transfusion speed, reduced labor intensity and enhanced work efficiency.

Description

Injector propeller

This utility model relates to a kind of propeller that is used to inject.

Injection is that treatment means, the especially intravenous injection of often using gone up in medical treatment, and amount of infusion is big, and the operating time is long, and requires to advance strength big and steady, so the running out of space of medical worker, and work efficiency is affected.

Present injecting propeller is to utilize spring or rubber band as power source, and it is fixed on an end of spring on the base, and an end links to each other with the needle tubing piston, utilizes its resilience force to promote piston.This propelling can not be regulated fltting speed at any time, and beginning elastic force is very big, and fltting speed is fast, and last elastic force is very little, and fltting speed is too slow, thereby causes fltting speed steady inadequately.

The purpose of this utility model provides a kind of scalable fltting speed, can make transfusion speed injecting propeller stably again simultaneously, and it is easy to use and reliable, increases work efficiency greatly.

This utility model is achieved in that uses clockwork spring as power source, and clockwork spring and drive are installed in the casing, utilizes the resilience of clockwork spring to rotate, and drives the piston motion of syringe, thereby reaches the purpose of injection.

Below in conjunction with accompanying drawing this utility model is further described.

Fig. 1 is a side view of the present utility model;

Fig. 2 is a longitudinal sectional drawing of the present utility model;

Fig. 3 is the front view of going to the bottom of control wheel.

As Fig. 2 a, ［ 6 ］ are by plastics, the columniform drive that timber or metal etc. is made, the circle of going to the bottom on it is bigger slightly than the cylindrical cross-section circle, and is empty in the cylinder, is through on the axle ［ 7 ］ by the round heart in two ends, driving-belt one end is fixed on the base, and the other end is wrapped on the cylinder of drive.［ 6 ' ］ are a clockwork spring, and it is contained in the drive, and an end of clockwork spring is fixed on the axle ［ 7 ］, and an end is fixed on the inwall of drive.［ 8 ］ be control wheel shown in Figure 3, it is fixed on the axle ［ 7 ］ from the center.［ 9 ］ be a stage clip, one end is fixed on the side plate inboard of casing ［ 1 ］, the other end is by key ［ 3 ］ control, and as shown in Figure 3, it can be pressed on the control wheel, axle ［ 7 ］ crosses casing ［ 1 ］ biside plate and frame at side plate, go up and can rotate, but can not move left and right, ［ 4 ］ are the handles that a help turns axle ［ 7 ］, it can be fixed on the axle ［ 7 ］, also can pull down.

This utility model also can be realized by the mode of Fig. 2 b.

Clockwork spring among Fig. 2 a separated from drive just become the structure shown in Fig. 2 b.［ 6 ］ be drive, its structure is through on the axle ［ 7 ］ by the round heart in two ends with identical shown in Fig. 2 a, but unfixing with it.［ 6 ' ］ for the tape box or not its end of clockwork spring of tape box be fixed on the axle ［ 7 ］ on, the other end is fixed on the casing ［ 1 ］; If the tape box, then the other end is fixed on the barrel, and barrel and casing ［ 1 ］ are fixing.Control wheel ［ 8 ］ is identical with Fig. 2 a with stage clip ［ 9 ］, just an end of stage clip ［ 9 ］ is not to be fixed on the casing ［ 1 ］, but be fixed on drive ［ 6 ］ and round of control wheel ［ 8 ］ bottom surface adjacent, the other end can be pressed on the control wheel ［ 8 ］ by key ［ 3 ］ control.Axle ［ 7 ］ crosses casing ［ 1 ］ side plate and frame on side plate, and can rotate but can not move left and right.Handle ［ 4 ］ is with identical shown in Fig. 2 a.

Earlier Transfusion needle pipe is stuck in the casing groove during this utility model work, and at the bottom of base ［ 5 ］ withstood the piston of syringe, press switch ［ 3 ］, allow stage clip ［ 9 ］ depress, and turn stubborn handle ［ 4 ］ and make clockwork spring ［ 6 ' ］ accumulation of energy, cause drive ［ 6 ］ to rotate after clockwork spring ［ 6 ' ］ accumulation of energy, the driving-belt ［ 10 ］ that is wrapped on the drive ［ 6 ］ just spurs base ［ 5 ］, thus the pushing syringe piston.If strength is not enough in progradation, can be rotated further handle ［ 4 ］ accumulation of energy, add high thrust; Excessive as thrust, can mention stage clip ［ 9 ］, allow axle ［ 7 ］ revolution release energy, reduce advancing strength.

This utility model is simple in structure, when injection advances, advances the strength drop little, and fltting speed is more steady, and general clockwork spring only turns around or less than the liquid infusion in the syringe being finished once enclosing.And the strength drop of clockwork spring after turning around is very little, and fltting speed can be selected temporarily according to patient's the state of an illness and physical condition, and regulates at any time in progradation.
