Abstract

An infusion flow regulator comprises a dial scale, pointers, a shaft, a driving gear, a driven gear, a screw rod, an infusion tube, gaskets and an outer casing, and is characterized in that the pointers are positioned inside the dial scale and welded together with the upper portion of the shaft, the shaft is closely matched with the driving gear, the driving gear is closely meshed with the driven gear, the screw rod is closely matched with the driven gear, the gaskets are arranged at both corresponding positions of the lower portion of the screw rod and the inside of the outer casing, and the infusion tube is positioned between the two gaskets. By the aid of the infusion flow regulator, flow during infusion can be controlled accurately, and great convenience is brought for medical staff.

Description

Infusion flow adjuster

Technical field

This utility model relates to a kind of medical apparatus and instruments, is specially infusion flow adjuster.

Background technology

The transfusion device of usefulness clinically, flow regulator of dress is made up of roller and leather hose groove on it, the bottom of leather hose groove is gradient, the transfusion leather strap is in the leather hose groove, scroll wheel, roller extruding transfusion leather strap, transfusion leather strap lacuna diminishes, and the medical worker is by the change of this lacuna of control, just reach the purpose of regulating infusion flow, because the change of this leather strap lacuna can't be expressed with the quantity of determining, the medical worker can only be dripped per minute by observation dropper giving drugs into nose and be dripped number, is used as judging whether the adjusting of flow regulator meets the requirements of foundation, different transfusion devices, the dropper medicine drips and varies in size, and drips number according to the dropper giving drugs into nose and judges and can not quantize the transfusion speed, and it is inaccurate, bring very big inconvenience for medical personnel and patient, when monitoring infusion is bad, also may cause malpractice.

The utility model content

The technical problem that this utility model solved is to provide infusion flow adjuster, to solve the shortcoming in the above-mentioned background technology.

The technical problem that this utility model solved realizes by the following technical solutions:

Infusion flow adjuster, comprise graduated disc, pointer, axle, driving gear, driven gear, screw rod, tube for transfusion, pad and shell, described graduated disc is positioned at the top of shell, described pointer is positioned at graduated disc inside, and weld together with the top of axle, described axle closely cooperates with driving gear, described driving gear and driven gear tight engagement, described screw rod and driven gear closely cooperate, the corresponding section, inside of the bottom of described screw rod and shell all is welded with pad, described tube for transfusion is between two pads, and the scale on the described graduated disc is the Fifteenth National Congress lattice, and each big lattice is represented five.

Beneficial effect

This utility model can accurately be controlled the flow in the infusion process, and it is very big convenient to have brought to medical personnel.

Description of drawings

Fig. 1 is a profile of the present utility model;

Fig. 2 is the sketch map of graduated disc of the present utility model.

The specific embodiment

For technological means, creation characteristic that this utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth this utility model.

Referring to Fig. 1, Fig. 2, the profile of infusion flow adjuster, the sketch map of the graduated disc of infusion flow adjuster, infusion flow adjuster, comprise graduated disc 1, pointer 2, axle 3, driving gear 4, driven gear 5, screw rod 6, tube for transfusion 7, pad 8 and shell 9, described graduated disc 1 is positioned at the top of shell 9, described pointer 2 is positioned at graduated disc 1 inside, and weld together with the top of axle 3, described axle 3 closely cooperates with driving gear 4, described driving gear 4 and driven gear 5 tight engagement, described screw rod 6 closely cooperates with driven gear 5, the corresponding section, inside of the bottom of described screw rod 6 and shell 9 all is welded with pad 8, described tube for transfusion 7 is between two pads 8, and the scale on the described graduated disc 1 is the Fifteenth National Congress lattice, and each big lattice is represented five.

During operation, pointer 2 is pushed the maximum scale place, after treating that liquid stream is stable, require pointer 2 is pushed the position of requirement according to transfusion, scale on the graduated disc 1 from zero to 15, every big lattice are represented five, when stirring pointer 2, pointer 2 can drive axle 3 rotations, thereby drive driving gear 4 rotations, because of driving gear 4 and driven gear 5 tight engagement, during driven gear 5 rotations, drive and driven gear 5 close-fitting screw rod 6 rotations, can drive the pad 8 that is welded on screw rod 6 bottoms during screw rod 6 rotations and move up and down, regulate the pad 8 that is welded on screw rod 6 bottoms and be welded on the pad relative position of shell 9 inside thereby reach, change the purpose that is clipped in two flows in the tube for transfusion 7 between the pad 8 thereby reach.

More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the description just illustrates principle of the present utility model; under the prerequisite that does not break away from this utility model spirit and scope; this utility model also has various changes and modifications; these changes and improvements all fall in claimed this utility model scope, and the claimed scope of this utility model is defined by appending claims and equivalent thereof.

Claims

1. infusion flow adjuster, comprise graduated disc, pointer, axle, driving gear, driven gear, screw rod, tube for transfusion, pad and shell, it is characterized in that, described pointer is positioned at graduated disc inside, and welds together with the top of axle, and described axle closely cooperates with driving gear, described driving gear and driven gear tight engagement, described screw rod and driven gear closely cooperate, and the corresponding section, inside of the bottom of described screw rod and shell all is welded with pad, and described tube for transfusion is between two pads.

2. infusion flow adjuster according to claim 1 is characterized in that described graduated disc is positioned at the top of shell.
