Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of teaching equipment models, and in particular to a male dog catheterization teaching model. Background Art
[0002] Because the male dog's urinary tract is very long, it extends backward along the middle of the pelvic floor wall, bypasses the ischial arch, turns into the base of the scrotum, and then turns into the ventral side of the penis, extending along the ventral side of the penis, and opening the glans penis. The urethra at the ischial arch and the base of the scrotum is relatively narrow, and stones caused by various reasons are difficult to be discharged from the body with urine here. With the development of pet clinical medicine, the detection rate of canine stones is getting higher and higher. Whether it is the emergency treatment of male dog urethral stones or bladder stone surgery, male dogs need to be catheterized. Due to the special physiological structure of the urethra, male dog catheterization brings great pain to dogs and may cause irreversible damage, which seriously violates the original intention of veterinary medicine and animal welfare. However, in clinical practice, male dogs are required to have proficient, fast and accurate catheterization techniques. To master the male dog catheterization technique, repeated practice is required. Therefore, male dog catheterization teaching aids are urgently needed. In pet clinical teaching, the existing teaching aids have poor simulation. The development of this model will greatly improve the difficulties faced in teaching. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0025] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0027] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0028] like Figure 1 As shown, the utility model provides a male dog catheterization teaching model, including a model body 1, wherein the model body 1 is provided with a penis module 2, wherein the front side of the penis module 2 is sequentially connected with a penis glans module 3 and a penis head extension module 4, wherein the outer surface of the penis head extension module 4 is covered with a penis foreskin 5; the penis module 2 is a hollow structure and is provided with a urethra 7 and a vas deferens 17, wherein the rear side of the penis module 2 is sequentially connected with a bladder module 11 and a prostate module 9, wherein the front side of the prostate module 9 is connected with a vas deferens 17, wherein the vas deferens 17 is connected with a testicle module 15 via an inguinal canal 16, and the bladder module 11 is connected with a kidney module 14 via a ureter 13.
[0029] A urethra pressure sensor 8 is provided in the urethra 7, and the urethra pressure sensor 8 is used to detect the pressure in the urethra 7. When the pressure in the urethra 7 is too high, the urethra pressure sensor 8 is triggered to alarm. The urethra pressure sensor 8 is detachably connected to the urethra 7, which is convenient for replacing wearing parts. A check valve 10 is provided at the connection between the bladder module 11 and the penis module 2. A bladder pressure sensor 12 is provided in the bladder module 11, and is used to detect the pressure in the bladder module 11. When the bladder pressure is too high, the bladder pressure sensor 12 is triggered to alarm. The bladder pressure sensor 12 is detachably connected to the bladder module 11, which is convenient for replacing wearing parts.
[0030] A plurality of foreskin pressure sensors 6 are provided on the foreskin 5 of the penis. When the hand exerts too much pressure on the foreskin 5 of the penis during catheterization, the foreskin pressure sensor alarm 6 may be triggered. The foreskin pressure sensor 6 is detachably connected to the foreskin 5 of the penis, so that wearing parts can be easily replaced.
[0031] The model body 1 is made of silicone material, and the model body 1 can be disassembled as a whole along the midsagittal plane.
[0032] A fixing port 18 is provided at the rear side of the model body 1, and the fixing port 18 is used to connect with an external device to fix the entire teaching model.
[0033] The working principle of the utility model is as follows: during catheterization, the foreskin 5 of the penis is held with one hand and pushed forward to fully expose the glans penis extension module 4, and the catheter is inserted into the urethra 7. If the foreskin 5 of the penis is held with too much force during the process of exposing the glans penis extension module 4 or inserting the catheter, the foreskin pressure sensor 6 will be triggered to alarm, simulating the damage to the foreskin and penis caused by violent catheterization during clinical catheterization.
[0034] During catheterization, if the catheter is successfully inserted, a syringe is used to push physiological saline into the catheter. If the injection speed is too fast, the pressure in the urethra 7 will be too high, which will trigger the urethra pressure sensor 8 to alarm, simulating the urethra injury caused by excessive flushing pressure when the urethra needs to be flushed in clinical practice.
[0035] During catheterization, if the urethra 7 is repeatedly flushed, too much liquid enters the bladder module 11, causing the pressure in the bladder module 11 to be too high, which will trigger the bladder pressure sensor 12 to alarm, simulating bladder damage caused by excessive flushing of the urethra in clinical practice.
[0036] During catheterization, if the catheter enters the bladder module 11 smoothly and the bladder capacity is not accurately estimated during simulated bladder flushing, the pressure in the bladder module 11 is too high, which will trigger the bladder pressure sensor 12 to alarm, simulating bladder damage caused by excessive amount of liquid entering the bladder during bladder flushing in clinical practice.
[0037] During the pathology course, the model body 1 is disassembled along the midsagittal plane to expose the prostate module 9, kidney module 14, testicle 15, inguinal canal 16, and vas deferens 17. Based on physiological anatomy, it is explained what testicular descent is, the classification of cryptorchidism caused by abnormal testicular descent, and how to find cryptorchidism in clinical practice.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
