[0026] The utility model will be introduced in detail and specifically through specific embodiments, so that the technical scheme of the utility model can be better understood. However, the following embodiments do not limit the scope of the utility model.

[0027] The utility model discloses a cow, horse ovary simulation teaching model, including the spherical hard shell body 1 of plastic material, the elastic ball sac 2 of rubber material, the catheter 3, the coupling body 4, one-way valve 5 and boost pump 6, as Figure 1 Indicated.

[0028] Among them, the hard shell body 1 is made of polyethylene or other plastic, for simulating ovary. Two or more than two size different circular holes 101 are formed on the wall surface of the hard shell body 1, and the diameter of the circular hole 101 is 5mm-20mm. The non-hole part of the outer surface of the hard shell body 1 is covered with the soft outer layer 102 made of rubber material, for simulating the soft form and touch of ovary. Meanwhile, the hard shell body 1 wall surface is also provided with connection hole 104 for being connected with the coupling body.

[0029] The soft outer layer 102 of the above-mentioned hard shell body 1 is designed with at least one protruding structure 103 at any position, which can be a solid hemispherical rubber particle with a diameter of 10mm-30mm, fixed on the soft outer layer 102 by cementing, for simulating the corpus luteum formed after the rupture of ovarian follicle and ovulation, training the recognition and palpation of the corpus luteum. The positions of the above-mentioned circular hole 101 and protruding structure 103 are not limited, and they are evenly distributed as much as possible.

[0030] The elastic balloon 2 is arranged inside the hard shell 1, the inlet end of the elastic balloon 2 is connected with the outlet end of the catheter 3 through the connecting hole 104 on the side wall of the spherical hard shell 1, the inlet end of the catheter 3 is connected with the outlet end of the booster pump 6, and the one-way valve 5 is installed on the catheter 3 near the outlet end of the booster pump 6 to limit the flow direction of the gas or liquid. Thus, the booster pump 6 can inject gas or liquid into the elastic balloon 2 through the catheter 3, so that the elastic balloon 2 is inflated to fill the hard shell 1; at this time, further pressurization is carried out, and finally the outer wall of the elastic balloon 2 protrudes through the circular through hole 101 on the wall of the hard shell 1 to form a spherical protrusion on the outer wall of the hard shell 1, which is used to simulate the follicle. The pressure gauge 501 is installed on the one-way valve 5 to display the pressure data in the elastic balloon 2 in real time. The best simulation effect of the follicle is obtained by combining the pressure data with the best pressure of the simulated follicle, so as to form quantitative specification for teaching training.

[0031] The coupling body 4 includes an elastic connecting rod 401 and a hard connecting rod 402. The elastic connecting rod 401 is a spiral rod made of elastic metal materials such as steel wire, which is similar to a spring structure, is sleeved outside the catheter 3, and is designed with a front connector 401a at the front end. The front connector 401a is connected and fixed with the connecting hole 104 on the hard shell 1 through clamping, and the end surface of the front connector 401a at the front end is in contact with the outer wall of the hard shell 1 after being fixed. The rear end of the front connector 401a is a cylindrical structure with an internal thread structure for connecting the hard connecting rod 402.

[0032] The hard connecting rod 402 is a hollow rod sleeved outside the elastic connecting rod 401, so that the elastic connecting rod 401 can be axially extended out of or retracted into the hard connecting rod 402. The inner wall of the front end of the hard connecting rod 402 is designed with an annular shoulder A402a, and the outer wall of the end of the elastic connecting rod 401 is designed with an annular shoulder B401b in the circumferential direction. The annular shoulder A402a and the annular shoulder B401b are matched to limit the extension length of the elastic connecting rod 401. Thus, the elastic connecting rod 401 and the hard connecting rod 402 form two positional relationships, i.e. the first end of one is connected with the second end of the other or they are nested with each other. In the state that the first end of one is connected with the second end of the other, the hard shell 1 connected with the elastic connecting rod 401 can swing, as shown in Figure 2 In this state, the annular shoulder on the inner wall of the front end of the hard connecting rod 402 and the annular shoulder at the end of the elastic connecting rod 401 are matched to prevent the elastic connecting rod 401 from coming out of the hard connecting rod 402. In the state that the first end of one is connected with the second end of the other, the hard shell 1 connected with the elastic connecting rod 401 can swing, as shown in Figure 3 In this state, the hard connecting rod 402 is fixedly connected with the rear end of the front connector 401a of the elastic connecting rod 401 through the external thread at the front end of the hard connecting rod 402 and the internal thread structure at the rear end of the front connector 401a of the elastic connecting rod 401.

[0033] The utility model discloses an ovary simulation teaching model, when applying, need with the trained student line of sight isolation of hard shell 1, make the trained student only can through hand touch perception to hard shell 1, specifically can set up in the hard shell 1 in a for simulating the trunk of an animal with the top cover box 7, and hard link 402 is placed in the through -hole that set up below the rear wall surface of box 7, through the design connection flange 402b on the outer wall of hard link 402, with the rear sidewall of box 7 cooperation through bolt connection fixed. Figure 4 As shown. Also can set up hard link 402 on support 9, through the support top end clamp 901 clamping fixed hard link, and in the front end of hard link 402 is equipped with a baffle 8, the baffle 8 is set up on the horizontal plane, and the hard shell 1 is separated with the student, and the baffle 8 is equipped with a circular arm entry port 701 on the position above hard link 402 for the arm of the student to extend into the other side of the baffle 8, as shown. Figure 5 As shown.

[0034] After setting up the hard shell 1 through the foregoing mode, the gas or liquid is filled into the elastic balloon 2 through the pipeline by the booster pump 6. The pressure is continuously increased by the booster pump 6, so that the elastic balloon 2 forms a spherical protrusion through the circular through hole 101 on the hard shell 1 under the action of internal pressure. Different sizes of spherical protrusions can be formed by designing different sizes of circular through holes 101 to simulate different sizes and soft and hard forms of follicles. The solid hemispherical rubber particle protrusion structure 103 fixed on the soft outer layer 102 simulates the corpus luteum. Thus, the students can be trained to palpate and identify follicles and corpus luteum in different states (size, soft and hard), and further diagnose the stages and states of the estrus cycle of cattle and horses.

[0035] Further according to the requirement, the elastic link 401 can be extended out of the hard link 402, so that the two are in a head-to-tail state. At this time, under the action of the elastic link 401, the position of the hard shell 1 is in a relatively movable state, which can be used to train the gripping ability of the trainees on the ovary. At the same time, the elastic link 401 can also be inserted into the hard link 402, so that the two are in a mutual nesting state. At this time, under the action of the hard link 402, the position of the ovary is in a relatively fixed state, which can be used to train the recognition and palpation ability of the trainees on the follicle and corpus luteum.
