Abstract
The utility model discloses an injector used in the operation process of ovum fetching operation, which comprises a needle nipple and an injector main body, wherein the needle nipple is provided with a horn-shaped inner cavity structure, one end with a larger inner diameter of the cavity is far away from the injector main body, and the other end with a smaller inner diameter of the cavity is integrally communicated with the injector main body; the injector body includes a barrel, a piston shaft, and a piston stem. The injector for the ovum taking operation process can conveniently and quickly insert the ovum taking needle into the injector, reduces unnecessary needle puncture of nursing staff, cancels the needle head of an original matched sleeve, and reduces waste and cost.
Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to an injector used in the operation process of an egg taking operation.
Background
Clinically, one nursing operation is to use a 20ml/0.8mm syringe containing sterile ovum culture solution in the process of ovum extraction operation, remove the needle, and insert the 35cm long needle of ovum extraction needle penetrating through the ovary tissue into the syringe through the nipple of the syringe to suck ovum culture solution for flushing. Because the inner diameter of the nipple of the injector is small, when an operator inserts the slender needle head of the egg taking needle into the nipple of the injector, the alignment is difficult, and the phenomenon that the needle head of the egg taking needle does not enter the injector and the finger is pricked to cause needle stabs is very easy to occur; moreover, the needle associated with the syringe itself is not a necessary item in this operation, and each operation would directly throw away the associated needle, resulting in unnecessary waste.
Disclosure of Invention
The utility model aims to solve the defects in the prior art and provides the injector for the operation process of the ovum taking operation, which is convenient to operate, avoids accidental injury and reduces waste.
In order to achieve the above purpose, the technical scheme adopted is as follows:
the utility model provides an injector for in ovum operation process of getting, includes needle nipple and syringe main part, the needle nipple has loudspeaker type inner chamber structure, and the great one end of cavity internal diameter is kept away from the syringe main part, and the little one end of cavity internal diameter and syringe main part integral type UNICOM make the ovum needle of getting can insert from the great one end of needle nipple cavity internal diameter, and the inside of syringe main part is got into after the little one end of cavity internal diameter of rethread, reduces the unnecessary needle puncture of nursing staff; the injector body includes a barrel, a piston shaft, and a piston stem.
As another preferable scheme of the utility model, the inner diameter of the joint of the nipple and the syringe main body is 2-4 mm, so that the passage of the ovum taking needle is facilitated.
As another preferable aspect of the present utility model, the shape of the nipple is one of funnel shape, cylindrical shape, prismatic shape or square shape.
As another preferable mode of the utility model, a needle cap matched with the larger end of the needle nipple is also arranged for sealing the needle nipple and preventing the liquid introduced into the injector from flowing out and being polluted.
Furthermore, the needle cap is connected with the needle nipple in a buckling or threaded mode, so that the needle cap is convenient to take down and install.
Compared with the prior art, the injector for the ovum taking operation process has the advantages that the ovum taking needle can be quickly and safely inserted into the injector main body through the needle nipple with the horn-shaped inner cavity, the operation is convenient and fast, the practicability is high, and unnecessary needle puncture of nursing staff is reduced; the nipple and the syringe main body are integrally formed, the structure is simple, the whole syringe can be directly packaged and disinfected, the needle head of an original sleeve is cancelled, and the waste and the cost are reduced.
Drawings
Fig. 1 is a schematic structural view of embodiment 1 of the present utility model, fig. 2 is a partially exploded schematic view of embodiment 1 of the present utility model, and fig. 3 is a schematic structural view of embodiment 2 of the present utility model.
Wherein: 1-needle papilla; 21-needle cylinder; 22-piston; 23-piston shaft; 24-piston handle; 3-needle cap.
Detailed Description
For a better understanding of the present utility model, specific embodiments of the utility model are described in further detail below with reference to the drawings.
Example 1
As shown in fig. 1 and 2, the injector for the ovum taking operation process comprises a needle nipple 1, an injector main body and a needle cap 3, wherein the needle nipple 1 is funnel-shaped and has a horn-shaped inner cavity structure, one end of the inner diameter of the cavity is far away from the injector main body, the other end of the inner diameter of the cavity is integrally communicated with the injector main body, and the inner diameter of the joint of the needle nipple 1 and the injector main body is 4mm; the injector body comprises a barrel 21, a piston 22, a piston shaft 23 and a piston stem 24; the needle cap 3 is matched with the larger end of the needle nipple 1, and the needle cap 3 is connected with the needle nipple 1 in a buckling manner.
When the device is used in clinical work, firstly, the piston 22 is pulled out, the culture solution is poured into the needle cylinder 21, then the piston 22 is put into the needle cylinder 21, the liquid is pushed to the end of the needle nipple 1, and the needle cap 3 is arranged on the needle nipple 1 for standby; during flushing, the needle cap 3 is taken down, the egg taking needle is inserted through one end with the larger inner diameter of the cavity of the needle nipple 1, then one end with the smaller inner diameter of the cavity of the needle nipple 1 enters the needle cylinder 21, and after flushing the egg taking needle by utilizing negative pressure suction flushing liquid in the egg taking needle, the egg taking needle is taken out for puncturing.
Example 2
As shown in fig. 3, the structure of example 2 constitutes reference example 1, and unlike example 1, the cap 3 and the nipple 1 of example 2 are screwed.
Compared with the prior art, the embodiment 1 and the embodiment 2 enable the ovum taking needle to be quickly and safely inserted into the syringe main body by the needle nipple 1 with the horn-shaped inner cavity, so that unnecessary needle stabs of nursing staff are reduced; the nipple 1 and the syringe main body are integrally formed, so that an original matched needle is omitted, and waste and cost are reduced; meanwhile, the device has the advantages of saving the time for installing and detaching the needle head and bringing convenience for nursing staff to pour the culture solution.
The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
