Technical Field

[0001] The utility model relates to a pet disease treatment device, in particular to a pet urinary catheter placement device. Background Art

[0002] With the continuous improvement of living standards, the scale of pet keeping by humans has continued to expand, giving rise to the emerging industry of pet hospitals, whose main business scope is to treat common diseases of pets. In the treatment of urinary and reproductive system diseases of pets such as female dogs and cats, it is often necessary to intubate and catheterize them. For adult small and medium-sized female dogs and cats, the urethral opening is located on the ventral wall of the vagina, 3 to 5 cm from the ventral joint of the vulva to the head. This part is deep in the vagina and cannot be seen directly with the eyes. For the above pet cases, there are two main intubation and catheterization techniques: one is that when the urethral opening cannot be seen directly with the eyes, it mainly relies on clinical experience, roughly touches the corresponding part with the hand, and then blindly inserts, which has a high failure rate; the other is to visually observe and determine the urethral opening with the help of the lighting function of the otoscope, and then the otoscope is detached and then the intubation is performed according to memory. This method uses visual memory as a reference, which improves the success rate to a certain extent, but its inspection and intubation are actually two separate steps, which is inconvenient to operate and the success rate of intubation needs to be improved.

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that the visual catheter placement device for a urinary catheter in a pet hospital of the utility model comprises an observation device and a urinary catheter 2, wherein the front end of the observation device is set as a sleeve 1, and further comprises a split-and-combined expansion tube 3 and a clamping device 4; the split-and-combined expansion tube 3 comprises two tube bodies with semicircular cross sections, wherein the two tube bodies are movably connected to each other on one side strip thereof, and notches 30 are symmetrically cut on the opposite side strip thereof, and when the two tube bodies are combined with each other, the two notches 30 cooperate to form a circular tube, and the two notches 30 cooperate to form an operation hole; the circular tube and the operation hole match the urinary catheter 2;

[0018] The split-and-combined expansion tube 3 is movably sleeved on the sleeve 1 , and the clamping device 4 is sleeved outside the split-and-combined expansion tube 3 to fix the split-and-combined expansion tube 3 on the sleeve 1 .

[0019] like Figure 1 , Figure 2 It can be seen that as one of the implementation methods, the clamping device 4 is set as a self-locking pipe clamp. The self-locking pipe clamp is a sheet metal part made of steel strip, has its own elasticity and is in a contracted state by default. When the operator pinches its two ears together at the same time, the pipe diameter of the self-locking pipe clamp expands and releases the lock. When the pressure disappears, the pipe clamp automatically shrinks and locks.

[0020] Embodiment 1

[0021] In this embodiment, the observation device is configured as a handheld otoscope.

[0022] like Figure 3 It can be seen that the handheld otoscope includes a main body 70 with a built-in battery, a peep window 71 is fixed to the upper end of the main body 70, the sleeve 1 is arranged at the end of the peep window 71, and a light source 72 connected to the battery is arranged in the main body 70, and the light source 72 has an irradiation direction pointing to the side of the sleeve 1.

[0027] B. The operator inserts the front end of the split-and-combined expansion tube 3 into the pet's body, and visually observes through the peep window 71, and positions the front end of the split-and-combined expansion tube 3 based on the visual results. After positioning, the urinary catheter 2 is inserted through the operation hole formed by the two notches 30 until the inflatable balloon 21 enters the appropriate position in the urethra. Then, the inflatable balloon 21 is inflated through the airway to expand and position it in the pet's body.

[0028] C. After the positioning of the urinary catheter 2 is completed in step B, the two ears of the self-locking tube clamp are pinched to expand the tube diameter, the endoscope and the tube clamp are separated, and the split-and-combined expansion tube 3 is separated into two left and right tube bodies after losing its restriction and separated from the urinary catheter 2. The catheterization is completed, and the urinary catheter 2 can work independently.

[0029] With the help of this device, pet urinary catheterization is completed under visual assistance, the positioning accuracy is significantly improved, the difficulty of catheterization is greatly reduced, and the success rate of catheterization is increased.

[0030] Embodiment 2

[0031] like Figure 5 It can be seen that in this embodiment, the observation device is configured as an electronic endoscope 5, which includes a lens 50 with its own light source, and also includes a focus button 51 connected to the lens 50, and a dimming button 52 connected to the light source; the observation device also includes a handle 6, and a positioning sleeve 60 is integrally formed on the upper end of the handle 6, and the sleeve 1 is integrally formed on the positioning sleeve 60, and the front end of the lens 50 is sleeved in the positioning sleeve 60; the electronic endoscope 5 is connected to a display device, and the connection method includes a data cable connection and a wireless connection, and the display device includes a mobile phone, a tablet computer or a microcomputer.

[0033] A. The self-locking pipe clamp and the split-and-joint expansion tube 3 are connected to one end of the positioning sleeve 60 via the sleeve 1; the lens 50 is connected to the other end of the positioning sleeve 60.

[0034] B. The operator inserts the front end of the split-and-joint expansion tube 3 into the pet's body, and the detection result of the lens 50 is output to the display device via the data line. In this embodiment, the display device uses a mobile phone. During the operation, the focus button 51 and the dimming button 52 are used to adjust the operation state.

[0035] The operation process is observed through the display device. After the front end of the split-and-combined expansion tube 3 is positioned, the urinary catheter 2 is inserted from the operation hole formed by the two notches 30 until the balloon enters the appropriate position in the urethra. Then, the airway is inflated to expand the inflatable balloon 21 and position it in the pet's body.

[0036] C. After the urinary catheter 2 is positioned, pinch the two ears of the self-locking tube clamp to expand the tube diameter, the sleeve 1 and the tube clamp are separated, and the split expansion tube 3 is separated into two left and right tube bodies after losing its restriction and separated from the urinary catheter 2, and the catheterization is completed.

[0037] This embodiment uses an electronic endoscope 5 for detection and expands the surgical field to the screen, which makes observation clearer and helps to accurately diagnose the disease; the pet doctor's posture is liberated, the operation is more convenient, and multiple people can observe and cooperate in the operation when necessary.

[0038] like Figure 6 It can be seen that this embodiment further optimizes the structure of the split-and-combined expansion tube.

[0039] The split-and-combined expansion tube 3 comprises a left tube body 31 and a right tube body 31', and the middle ends of the left tube body 31 and the right tube body 31' are both provided with a truncated cone 32 with a semicircular cross section, one of the truncated cones 32 is cut with a groove along its longitudinal axis, and the other truncated cone 32 is matched with a protrusion, and the groove and the protrusion are connected to each other at the bottom of the truncated cone 32 through a pin 34; when the two truncated cones 32 are buckled together, the left tube body 31 and the right tube body 31' cooperate to form a circular tube, and the two notches 30 cooperate to form an operating hole, and the urinary catheter 2 is inserted from the operating hole; when the two truncated cones 32 are separated from each other, the mutual restriction between the split-and-combined expansion tube 3 and the urinary catheter 2 is released.

[0040] After adding the truncated cone 32, the left tube body 31 and the right tube body 31' are connected to each other by a pin at the truncated cone part. The left tube body 31, the right tube body 31' and the pin 34 are independent of each other. First, it is easy to produce and assemble; second, due to the split structure, it can be prepared as a metal part. Under the premise of ensuring rigidity, the wall thickness of its front end can be further reduced. At the same time, the split expansion tube 3 can be set as a tapered tube, which is more convenient to operate.

[0041] The specific implementation methods of the present invention include but are not limited to the above-mentioned embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations according to the present invention, but still fall within the protection scope of the present invention.
