Abstract

The utility model discloses a kind of breeder inseminating syringes, including an injector for medical purpose, the piston nose face central location of syringe is equipped with a compressed spring, and the block of backward stroke of the piston is fixed on syringe inner wall, and a bionical semen deposition pipette tips are fitted in the small bore columns of syringe front end.The utility model can quantitative essence, semen deposition, sperm extraction amount and insemination dose are determined by the dealing stroke of piston, and the dealing stroke of piston is set by compressed spring and block, therefore, are operated very simple.The utility model can be reused after high-temperature sterilization, can also be disposable.Bionical semen deposition pipette tips be it is disposable, can effectively avoid cross-infection between breeder, safety is higher.

Description

Breeder inseminating syringe

Technical field

The utility model belongs to veterinary instruments technical field, is related to a kind of breeder spermatic gun.

Background technique

Breeder artificial insemination's technology has been in a poultry propagation using very mature technology, but for decades, people Work semen deposition is always to use pipette as semen deposition tool, in operation, not only takes essence, semen deposition dosage inaccurate, Er Qierong It easily blows air into hen oviduct, rate of fertilization is caused to reduce.Hurt the defeated ovum of hen additionally, due to easy insert of tube head of pipette Pipe, thus the technical experience of operator is required high.There is a kind of spermatic gun to emerge, but this spermatic gun is in semen deposition process in recent years In biggish pressure is applied with to sperm, cause the quality of sperm to be damaged, fertility rate of hatching egg caused to be decreased obviously.

Summary of the invention

In view of this, the utility model proposes one kind can quantitative essence, semen deposition, and convenient for operation breeder inseminating syringe.

The technical solution of the utility model is a kind of breeder inseminating syringe, including an injector for medical purpose, it is characterised in that: The piston nose face central location of syringe is equipped with a compressed spring, and the block of backward stroke of the piston is fixed on syringe inner wall, A bionical semen deposition pipette tips are fitted in the small bore columns of syringe front end.

Further, the piston is a T-type piston, and the compressed spring is sleeved on the stick harness of T-type piston, and stick harness is inserted In the aperture of syringe front end, and the inner wall clearance fit with aperture；The front end face of the syringe is equipped with gas vent.

Further, the range of the piston is adapted to the sperm extraction amount of setting.

Further, the free height of the compressed spring is greater than the range of piston.

Further, the specification of the syringe is 1 milliliter or 2 milliliters.

In use, bionical semen deposition pipette tips are inserted into the small bore columns of syringe front end, piston is pushed, then bionical semen deposition Pipette tips insertion is stored up in the sperm of smart cup, and the handle of piston push rod is unclamped, and compressed spring resets naturally at this time extracts sperm, finally will Bionical semen deposition pipette tips are inserted into hen oviduct, push piston to the end.Since sperm extraction amount is equal with insemination dose, and sperm Extraction amount and insemination dose are to be determined by the dealing stroke of piston, and the dealing stroke of piston is set by compressed spring and block It sets, therefore, operates very simple.In addition, the utility model structure and uncomplicated, cost is not high, can be after high-temperature sterilization It reuses, it can also be disposable.Bionical semen deposition pipette tips be it is disposable, can effectively avoid cross-infection between breeder, pacify Quan Xinggeng high.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model one embodiment.

Fig. 2 is the structural schematic diagram of another embodiment of the utility model.

In figure: 1. syringes, 2. pistons, 3. compressed springs, 4. small bore columns, 5. bionical semen deposition pipette tips, 6. blocks, 7. stick harnesses, 8. gas vent.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing and have The utility model is described in further detail for body embodiment.

As shown in Figure 1, the utility model includes the injector for medical purpose that a specification is 1 milliliter, which includes syringe 1,1 front end small bore columns 4 of piston 2 and syringe, 2 front end face central location of piston are equipped with a compressed spring, the inner wall of syringe 1 On be fixed with the block 6 of backward stroke of the piston limit, block 6 is also possible to retaining ring, a bionical semen deposition pipette tips is fitted in small bore columns 4 5, the Patent No. ZL201620121901.0 of the bionical semen deposition pipette tips.

As a kind of improvement of the utility model, as shown in Fig. 2, the present embodiment is 2 milliliters using a specification Injector for medical purpose, piston 2 are designed as T-type piston, and compressed spring 3 is sleeved on the stick harness 7 of T-type piston, and stick harness 7 is inserted into aperture In the aperture of column 4, and the inner wall clearance fit with aperture；Gas vent 8 there are two being set on the front end face of syringe 1.Such design Air is brought into when can be to avoid semen deposition.

In the utility model, the range of piston 2 is adapted to the sperm extraction amount of setting.Such as 2 milliliters of medical injection Emitter is constructed according to shown in Fig. 2, and the range of piston 2 is determined as 6mm, and the extraction amount of sperm is 25~30 microlitres；If It using 1 milliliter of tubule injector for medical purpose, is constructed according to shown in Fig. 1, the range of piston 2 is determined as 5mm, the pumping of sperm Taken amount is 25~30 microlitres.

In the utility model, the free height of compressed spring is greater than the range of piston, in case piston cannot answer completely Position.
