Abstract

The utility model belongs to medical appliances, and particularly relates to a portable insulin syringe which comprises an injection tube, a piston, a syringe needle and a protection cap, wherein the outer side of the piston is fixedly connected with an internal threaded pipe, a threaded rod, which is in threaded fit with the internal threaded pipe, is arranged outside the internal threaded pipe, the outer end of the threaded rod is connected with a rotatable pressing handle, and scales are arranged on the threaded rod. The portable insulin syringe has the advantages of small volume, simple structure, convenience for carrying and the like; and the injection dosage can be conveniently adjusted according to the patient condition, the operation is relatively simple, and the protection cap is arranged at the position of the syringe needle, thus the portable insulin syringe is safe and reliable.

Description

Portable insulin injector

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially is a kind of device that is used for injection of insulin.

Background technology

For diabetics, insulin injection is a kind of commonly used and effective method.Because insulin requirement is injected at regular time and quantity, the patient often need carry injection device, and present injector for medical purpose obviously can not satisfy this requirement.And the normally used injection pen of patient can be carried at present, but is generally imported product, and the insulin pen-cartridge price supporting with it is comparatively expensive, has brought the certain economic burden to the patient, and in operation, has certain difficulty.

The utility model content

For overcoming above-mentioned technical problem, it is a kind of simple in structure, easy to carry that this utility model provides, and can carry out the portable insulin injector of calibrated shot at any time.

For realizing above-mentioned technical purpose, this utility model is to adopt following technical scheme to realize: a kind of portable insulin injector comprises a syringe; Be provided with piston in the syringe and be provided with syringe needle at front end, it is characterized in that: the syringe front end outside is provided with the head protector of threaded engagement, and head protector front end center has aperture; The piston outside is fixedly connected with riffled tube; The riffled tube outside is provided with the threaded rod of threaded engagement, and syringe is stretched out in the threaded rod outer end, and is fixedly connected with rotatable handle; Threaded rod is provided with scale, and syringe rear end and threaded rod keep sealed sliding movingly.

During use, through the exposure situation of rotation head protector may command syringe needle, in advance with being filled insulin preparation in the syringe; Through head protector that syringe needle is hidden then; And rotate rotatable handle it is contacted with the syringe tail end, so both guaranteed to be easy to carry its advantages of small volume; And guaranteed that syringe needle does not expose, the antibacterial or stab user of avoiding infection; When needs of patients is injected; The rotation head protector exposes syringe needle, and regulates the rotatable scale that shows by shank and regulate injection volume, after regulating syringe needle is inserted and subcutaneously presses rotatable handle and promptly accomplish injection; Because rotatable handle is got back to original position, same operation got final product when used next time.

The utlity model has advantages of small volume, simple in structure, advantage such as easy to carry, injection volume can be regulated according to patient's situation easily, operates fairly simplely, and the syringe needle place is provided with head protector, and is safe and reliable.

The specific embodiment

Referring to accompanying

drawing

1,2, be provided with piston 2 in the syringe 6 and be provided with syringe needle 1 at front end, it is characterized in that: syringe 6 front end outsides are provided with the head protector 7 of threaded engagement; Head protector 7 front end centers have aperture; Can supply syringe needle 1 to pass, piston 2 outsides are fixedly connected with riffled tube 3, and riffled tube 3 outsides are provided with the threaded rod 5 of threaded engagement; Syringe 6 is stretched out in threaded rod 5 outer ends; And be fixedly connected with rotatable handle 4, threaded rod 5 is provided with scale, and syringe 6 rear ends and threaded rod 5 keep sealed sliding movingly.

During use, through head protector 7 that syringe needle 1 is hidden then in advance with being filled insulin preparation in the syringe 6, and rotate rotatable handle 4 it is contacted with syringe 6 tail ends; When needs of patients is injected; Rotation head protector 7 exposes syringe needle 1; Regulate injection volume through rotatable handle 4 according to the scale that shows; Insert syringe needle 1 subcutaneous after regulating and press rotatable handle 4 and promptly accomplishes injection,, adopt said method to operate equally when use next time and get final product because rotatable handle 4 is got back to original position.
