Abstract
The present invention relates to an insemination catheter, in particular a piston type insemination catheter, comprising an insemination catheter body and a luer fitting, said insemination catheter body being mounted on said luer fitting, further comprising: a piston slidably inserted in said insemination catheter body; and the inner core is fixed at the end part of the inner core, the inner core is movably inserted in the insemination catheter body, and the piston and the inner core are used for pushing semen from the insemination catheter body to the uterus. When the piston type insemination catheter provided by the utility model is used, only the tail end of the insemination catheter needs to be inserted into the uterus, and then semen is injected into the uterus through the inner core and the piston, so that the stimulation to the uterus can be effectively reduced, the pain is reduced, and the sperm can be naturally eliminated due to a certain distance from the oviduct, so that the quality of fertilized eggs can be improved.
Description
Technical Field
The present invention relates to a insemination catheter, in particular a piston type insemination catheter.
Background
The existing insemination catheters are directly inserted into the bottom of the uterus, and the injector is pushed to inject semen close to the oviduct. The distal end of the insemination catheter needs to be pressed against the uterine wall, so that the uterus is stimulated greatly and pain is caused easily.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a piston type insemination catheter which does not need a syringe, does not need to support the tail end of the insemination catheter against the wall of uterus, can reduce the stimulation to the uterus and the pain, and can naturally eliminate sperms, and the specific technical proposal is as follows:
a piston insemination catheter comprising a insemination catheter body and a luer fitting, said insemination catheter body mounted on said luer fitting, further comprising: a piston slidably inserted in said insemination catheter body; and the inner core is fixed at the end part of the inner core, the inner core is movably inserted in the insemination catheter body, and the piston and the inner core are used for pushing semen from the insemination catheter body to the uterus.
Preferably, the external diameter of the insemination catheter body is 2.0-2.4 mm, the internal diameter of the insemination catheter body is 1.4-1.8 mm, the diameter of the piston is not smaller than the internal diameter of the insemination catheter body, and the diameter of the inner core is 1.0-1.4 mm.
Preferably, the end of the insemination catheter body is provided with a rounded corner.
Preferably, the external surface of the insemination catheter body is provided with scales.
Wherein, the piston is the silica gel piston.
Further, the inner core is made of PE, PC, stainless steel, nickel-titanium alloy or ABS material.
Compared with the prior art, the utility model has the following beneficial effects:
when the piston type insemination catheter provided by the utility model is used, only the tail end of the insemination catheter needs to be inserted into the uterus, and then semen is injected into the uterus through the inner core and the piston, so that the stimulation to the uterus can be effectively reduced, the pain is reduced, and the sperm can be naturally eliminated due to a certain distance from the oviduct, so that the quality of fertilized eggs can be improved.
Drawings
Fig. 1 is a schematic view of a configuration of a piston type insemination catheter;
fig. 2 is a cross-sectional view of a piston type insemination catheter.
Detailed Description
The utility model will now be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the piston type insemination catheter comprises a insemination catheter body 1 and a luer connector 3, wherein the insemination catheter body 1 is arranged on the luer connector 3, and the insemination catheter also comprises: the piston 4 is inserted in the insemination catheter body 1 in a sliding way; and the inner core 2, the piston 4 is fixed at the end part of the inner core 2, the inner core 2 is movably inserted into the insemination catheter body 1, and the piston 4 and the inner core 2 are used for pushing semen from the insemination catheter body 1 to the uterus.
The external diameter of the insemination catheter body 1 is 2.0-2.4 mm, the internal diameter is 1.4-1.8 mm, the diameter of the piston 4 is not less than the internal diameter of the insemination catheter body, and the diameter of the inner core is 1.0-1.4 mm.
The diameter of the inner core 2 is smaller than the inner diameter of the insemination catheter body 1, the friction force between the inner core and the insemination catheter body 1 is small, and the piston 4 is convenient to push to move.
The end of the insemination catheter body 1 is provided with a rounding off. The rounded corners enable the end of the insemination catheter to be smooth, and when the insemination catheter is inserted into the cervix, stimulation to the cervix and the uterus can be reduced, and pain is reduced.
The outer surface of the insemination catheter body 1 is provided with scales. The scale facilitates viewing of the depth of insertion into the uterus.
The piston 4 is a silica gel piston 4. The piston 4 is fixed on the inner core 2 by glue.
The inner core 2 is made of PE, PC, stainless steel, nickel-titanium alloy or ABS.
The tail end of the inner core 2 is conical and is matched with the inner conical joint at the tail end of the handle, when the tail end of the inner core 2 is matched with the handle, the piston 4 just reaches the end part of the insemination catheter body 1, namely is flush with the end part of the insemination catheter body 1 and does not exceed the end part of the insemination catheter body 1, and the uterus is prevented from being damaged.
The operation in-process drives piston 4 by inner core 2 and promotes forward, only need with the end of insemination pipe insert the uterus inside can, with the wall contactless of uterus, then pour into the inside of uterus with semen through inner core 2 and piston 4, can effectively reduce the stimulation to the uterus, reduce pain to because have certain distance apart from the oviduct, enable the sperm and carry out the natural elimination, can improve the quality of fertilized egg.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the utility model and should not be construed in any way as limiting the scope of the utility model. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive step, which shall fall within the scope of the appended claims.
