Abstract

The utility model discloses an injection syringe with a syringe needle protective jacket for fish artificial propagation, relates to an injection syringe for fish artificial propagation, and aims at solving the problem that a fish is easily damaged or easily dies when the injection syringe is used for injecting medicine into the fish. The injection syringe comprises a syringe, a piston, a core pin, a syringe needle and the protective jacket, wherein the syringe needle comprises a needle stem and a pintle; the protective jacket comprises a round tube and a strengthening ring; the front end of the needle stem is machined into a sharp shape; the rear end of the needle stem is fixed on the pintle; the front end face of the round tube is machined into a smooth surface; the rear end of the round tube is fixed with one end of the strengthening ring; the centre line of the round tube coincides with the centre line of the strengthening ring; the front end of the core pin is fixedly connected with the piston; the piston is arranged in the syringe; the excircle face of the piston is contacted with the inner wall of the syringe; the needle stem is fixedly sleeved on the outer wall of the liquid outlet of the syringe; and the strengthening ring is sleeved on the outer wall of the needle stem, and is arranged close to the front face of the syringe. The injection syringe is used for the field of fish artificial propagation.

Description

A kind of artificial propagation of fish syringe that has protective sleeve of syringe needle

Technical field

This utility model relates to a kind of artificial propagation of fish syringe, is specifically related to a kind of artificial propagation of fish syringe that has protective sleeve of syringe needle.

Background technology

In the artificial propagation of fish process, need be to injection lutein releasing hormone analog (LRH-A in the fish body ₂), chorionic-gonadotropin hormone (HCG), salmon releasing hormone analog (S-GnRH-A) and DOM (DOM) etc. carry out medicine and hasten parturition, and generally adopt the injection of pectoral fin base portion body cavity and two kinds of methods of dorsal fin base portion intramuscular injection.But because the majority that buys on the market is the syringe that human or large-scale domestic animal is used, its syringe needle is all longer, is about 4～5cm.And different Fish size individual differences are bigger, and health is than stick-slip, and the fish body is easily beated again, artificial difficult control when medicine is injected.At present, the shortcoming that exists during artificial propagation of fish injection oxytocic drug has: 1. the fish body is when beating, and syringe needle penetrates the difficult control of the degree of depth in the body; 2. easily prick skeleton during intramuscular injection, cause certain injury of fish body; 3. the body cavity injection is easily pricked on heart or internal, causes the death of fish body.

The utility model content

This utility model damages fish or dead problem during injectable drug in the fish body easily in order to solve with syringe, and then provides a kind of artificial propagation of fish with the syringe that has protective sleeve of syringe needle.

This utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described syringe comprises injection tube, piston, core bar and syringe needle, and described syringe also comprises protective sleeve; Syringe needle comprises pin stalk and pintle; protective sleeve comprises pipe and reinforcing ring; the front end of pin stalk is processed into pointed; the rear end of pin stalk is fixed on the pintle; the front end face of pipe is processed with round slip surface; one end face of the rear end of pipe and reinforcing ring is fixed; and the centrage of pipe and the central lines of reinforcing ring; the front end of core bar is fixedlyed connected with piston; piston is arranged in the injection tube, and the periphery of piston contacts with the inwall of injection tube, and pin stalk fixed cover is located on the liquid outlet outer wall of penetrating tube; reinforcing ring is set on the outer wall of pin stalk, and the close front end face setting of reinforcing ring.

The utlity model has following beneficial effect: this utility model stops by the syringe protective sleeve; it is easy to control that syringe needle penetrates the degree of depth of fish body; the last end of pipe is processed with round slip surface and has prevented the injury of protective sleeve to the fish surface simultaneously; the utlity model has the saving cost, characteristics simple in structure, that usability is strong.

The specific embodiment

The specific embodiment one: present embodiment is described in conjunction with Fig. 1, the described a kind of artificial propagation of fish syringe that has protective sleeve of syringe needle of present embodiment, described syringe comprises injection tube 1, piston 2, core bar 3 and syringe needle 4, it is characterized in that: described syringe also comprises protective sleeve 5; Syringe needle 4 comprises pin stalk 4-2 and pintle 4-1; protective sleeve 5 comprises pipe 5-1 and reinforcing ring 5-2; the front end of pin stalk 4-2 is processed into pointed; the rear end of pin stalk 4-2 is fixed on the pintle 4-1; the front end face of pipe 5-1 is processed with round slip surface 5-3; the end face of the rear end of pipe 5-1 and reinforcing ring 5-2 is fixed; and the central lines of the centrage of pipe 5-1 and reinforcing ring 5-2; the front end of core bar 3 is fixedlyed connected with piston 2; piston 2 is arranged in the injection tube 1, and the periphery of piston 2 contacts with the inwall of injection tube 1, and pin stalk 4-2 fixed cover is located on the liquid outlet outer wall of penetrating tube 1; reinforcing ring 5-2 is set on the outer wall of pin stalk 4-2, and reinforcing ring 5-2 is near 1 front end face setting.

The specific embodiment two: present embodiment is described in conjunction with Fig. 1; the described a kind of artificial propagation of fish syringe that has protective sleeve of syringe needle of present embodiment; described pipe 5-1 and the fastening setting of pin stalk 4-2, so more accurate to the position of fish body injection, make other identical with the specific embodiment one.

Operation principle:

At first according to the size of fish body and the position of injection; estimation will penetrate the degree of depth of pin stalk in the fish body body; select the length of protective sleeve and pin stalk, make protective sleeve be set in length that the pin stalk leaks outside and institute and estimate and to penetrate the interior pin of fish body body to obstruct length close, then the fish body is carried out injectable drug.
