Problems solved by technology

In actual operation, after the needle of the insulin syringe is inserted into the dosing tube, the entire needle is in the dosing tube, and insulin is easy to stick
As a result, only a part of the original small dose of insulin is mixed into the glucose solution after the injection, and the other part actually adheres to the inner wall of the dosing tube. In the end, the patient does not receive the expected dose of insulin injection, which affects the curative effect.

Embodiment 1

[0029] like figure 2 As shown, the present invention discloses a special insulin syringe for intravenous infusion, including a syringe body and a needle, wherein, the syringe body includes an empty cylinder 1 and a stem 2 slidingly installed in the hollow barrel 1, and the stem 2 is located in the hollow A piston 3 is mounted on one end of the barrel 1; the needle head includes a needle seat 4 detachably mounted on the end of the empty barrel 1, and a needle tube 5 is provided at the front end of the needle seat 4, and a needle point is arranged on the needle tube 5. like image 3 As shown, one of the designs: the needle tube 5 is a telescopic needle tube, and the telescopic needle tube includes a multi-section continuously sleeved short tube with variable diameter, and the needle point is located on a short tube with the smallest diameter; or, as Figure 4 As shown, the second design: the needle tube 5 is a whole elastically deformable metal wire tube, and the needle point ...

Embodiment 2

[0034] As an improved design on the basis of the foregoing embodiment 1, such as Image 6As shown, the syringe body is also provided with a flushing structure for flushing out the remaining insulin droplets in the empty barrel 1 and the needle tube 5 . In the aforementioned design, the needle tube 5 is lengthened so that it can be inserted into the infusion bag, but on the other hand, the infusion channel of the needle tube 5 is also extended, so that a small amount of insulin droplets remains in the needle tube 5, and a small amount remains in the empty cylinder 1 and the piston 3 in the tiny gaps between. Aiming at this kind of trace residue, the flushing structure is designed to enclose it into the infusion bag, further reducing the loss of insulin dose.

[0035] In one implementation form of the flushing structure, the core rod 2 is provided with a first flushing channel 6 penetrating through the core rod 2, and the piston 3 is provided with a second flushing channel 7 co...

Embodiment 3

[0037] This embodiment discloses the second realization form of the flushing structure, such as Figure 7 As shown, the flushing structure is a short flushing pipe 10 arranged on the end of the empty cylinder 1 away from the core rod 2. The short flushing pipe 10 communicates with the inner space of the empty cylinder 1, and the outer end of the short flushing pipe 10 is provided with a Rinse the second rubber stopper 11 of the short tube 10. This method also belongs to the liquid flushing design, which is the same as the previous design principle, except that the flushing position is replaced at the front end of the empty barrel 1, and communicates with the inner space of the empty barrel 1. The insulin in the insulin syringe is injected into the infusion bag first, and then Add a few milliliters of glucose solution from the flushing short tube 10, and flush a small amount of insulin remaining in the gap in the empty tube 1 and in the needle tube 5 into the infusion bag.

Abstract

The invention discloses a special insulin syringe cooperating with intravenous drip. The special insulin syringe comprises a syringe body and a needle, wherein the syringe body comprises a hollow cylinder and a core rod slidably mounted in the hollow cylinder, and a piston is mounted at one end, positioned in the hollow cylinder, of the core rod; the needle comprises a needle seat detachably mounted at the end of the hollow cylinder, a needle tube is arranged at the front end of the needle seat, and a needle tip is arranged on the needle tube; the needle tube is a telescopic needle tube, the telescopic needle tube comprises a plurality of sections of variable-diameter short tubes which are continuously connected in a sleeved mode, and the needle tip is located on the section of short tube with the smallest diameter; or, the needle tube is a whole metal line tube capable of elastically deforming, and the needle tip is located at the end, away from the needle base, of the metal line tube. The improved syringe needle is provided with a variable-length needle tube or a deformable lengthened needle tube, so that the loss of insulin can be reduced, enough insulin can be intravenously injected into the body of a patient, and the curative effect is ensured.

Description

technical field [0001] The invention relates to the technical field of insulin injectors, in particular to an insulin injector specially used for intravenous infusion. Background technique [0002] As an important drug for the treatment of diabetes, insulin is administered in addition to the common subcutaneous injection, intravenous injection, jet injection, etc. Among them, intravenous injection is mostly used when intravenous supplementation of sugar-containing preparations is required. According to the specific situation, an appropriate proportion of regular insulin (also known as short-acting insulin, regular insulin, etc.) is added to the glucose solution to help the input glucose enter the tissue cells and be used It is also used for the treatment of acute complications of diabetes (ketoacidosis, hyperosmolar coma, infection, etc.), and the liquid containing insulin is prepared according to a certain concentration, which is injected intravenously or pumped by a micro-...
