Abstract

The utility model discloses a syringe aspiration booster whose main body is a frame. One end of the frame shapes like a blocking opening and is in slide cooperation with the outer wall of the syringe, the other end is in buckling connection with the inner core of the syringe. The utility model is used on normal syringe. The needle core is pulled outward by one hand rather than two hands, thus the other hand is spared to conveniently fix the lesion site, and the aspiration part is more accurate, the formed negative pressure is higher, and the biopsy positive rate of needle absorption is higher.

Description

A kind of syringe pump booster

Technical field

This utility model relates to a kind of small-sized medical instrument of medically usefulness, refers in particular to a kind of syringe pump booster.

Background technology

Syringe major function commonly used is used for the various medicines of injection, the core of firmly pushing pin downwards during operation, but the outside pull nook closing member of just need exerting oneself when being used for aspiration biopsy, if two hands while pulls, just can form bigger negative pressure, but be difficult to the fixed needle position this moment, if a hands fixed needle, the formed negative pressure of the singlehanded suction of another hands is just less.At present, the good solution of Shang Weiyou.

Summary of the invention

The purpose of this utility model provides a kind of negative pressure syringe pump booster big, extracting force in the time of can increasing the suction of diseased region pin of being convenient to operate, produce.

The purpose of this utility model is achieved in that its main body is the frame type, and the one end is the bayonet socket shape and is slidingly matched with the outer wall of syringe that the inner core of the other end and syringe is connected together.

The technological progress that this utility model is obtained is: this utility model uses on syringe commonly used, make the outside pull nook closing member of original both hands become singlehanded pull nook closing member, vacate the another hands can be easily fixing diseased region, make the suction position more accurate, formed negative pressure is bigger, and the aspiration biopsy positive rate is higher.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the B of Fig. 1 is to view.

Fig. 3 is that the A of Fig. 1 is to view.

The specific embodiment

As shown in Figure 1, 2, 3, its main body of this utility model (2) is the frame type, and one end (3) is slidingly matched for the bayonet socket shape and with the outer wall of syringe, and the other end (1) is connected together with the inner core of syringe.Its operation principle is as follows: during use, this device and syringe are fixed, the operator just can one hand hold handle firmly, and plunger is outside pull just, and the another hands can fixed needle, can also be constantly to the different directions inserting needle.From mechanics principle, because the effect of aid is arranged, hold and be convenient to firmly, can make to form bigger negative pressure in the syringe, thereby the positive rate of aspiration biopsy is obviously improved.In addition, suction when this device also can be used for the nurse and makes up a prescription can significantly reduce nurse's labor intensity.

Claims

1, a kind of syringe pump booster is characterized in that: its main body (2) is the frame type, and one end (3) is slidingly matched for the bayonet socket shape and with the outer wall of syringe, and the other end (1) is connected together with the inner core of syringe.
