Description

Ureteral catheter with connector

Technical Field

The utility model relates to the technical field of ureteral catheters, in particular to a ureteral catheter with a joint.

Background Art

The ureter is a tube that is inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. After the ureter is inserted into the bladder, there is an air bag near the head of the ureter to fix the catheter in the bladder and prevent it from falling out. The connecting tube at the other end of the ureter is connected to a urine bag to collect urine.

Most of the existing urine collection methods are to directly connect the elastic joint tube at the end of the ureter to the urinary catheter on the urine bag to achieve the urine collection process. Although the elasticity of the joint tube can increase the friction with the urinary catheter, when the urinary catheter is hooked or caught, the joint tube and the urinary catheter will still be separated, resulting in urine leakage, a strong odor, and the bed sheets and pants are easily wetted by urine, which brings pain to the patient; it affects the nurse's accurate recording of urine volume, and the frequent replacement of bed sheets and patient pants increases clinical nursing work.

Utility Model Content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a ureteral catheter with a connector. The utility model pulls down an annular sliding handle to force a plurality of clamping plates arranged in an umbrella shape to clamp the connection between the connector tube and the urinary catheter, thereby increasing the friction force and preventing the connector tube from being separated from the urinary catheter due to being hooked, thereby preventing pain for the patient and reducing the labor intensity of the nurses. Then, the annular sliding handle is rotated to move the slider into the limit opening, thereby preventing the slider from moving up, resulting in the inability of the clamping plate to effectively press the connection between the connector tube and the urinary catheter.

In order to achieve the above purpose, the utility model provides the following technical solutions:

A ureteral catheter with a joint comprises a catheter body, one end of which is provided with an air bag, the other end of which is installed with a joint pipe, the outer sleeve of which is provided with a sliding clamping device, the sliding clamping device comprising a first annular plate fixedly connected to one end of the joint pipe, a plurality of clamping plates which are arranged on the outside of the joint pipe in an array at the bottom of the first annular plate, a plurality of outer walls of the clamping plates are provided with sliding grooves, a plurality of sliding grooves are installed inside the plurality of sliding grooves, a plurality of limiting openings are arranged in an array on one side of the sliding groove, and the outsides of the plurality of sliding blocks are connected to the same annular sliding handle.

Preferably, a ball bearing is provided on the surface of the sliding block abutting against the sliding groove, and a rubber layer is applied on the side of the clamping plate close to the joint pipe.

Preferably, the first annular plate and the pressing plate are both made of hard plastic, and a plurality of the pressing plates are connected to the first annular plate in an umbrella shape.

Preferably, the diameter of the joint pipe gradually increases from one end of the first annular plate toward one end of the second annular plate.

Compared with the prior art, the beneficial effects of the utility model are:

1. The utility model has a simple structure. By pulling the annular sliding handle downward, a plurality of clamping plates arranged in an umbrella shape are forced to clamp the connection between the joint tube and the urinary catheter, thereby increasing the friction between the joint tube and the urinary catheter, thereby preventing the joint tube from being separated from the urinary catheter due to being hooked, thereby avoiding pain for the patient and reducing the labor intensity of the nurses. Then, by rotating the annular sliding handle, the slider is moved into the limiting opening, thereby preventing the slider from moving upward, resulting in the inability of the clamping plate to effectively press the connection between the joint tube and the urinary catheter.

2. The slider of the device moves inside the slide groove through the ball bearing, which can reduce the friction between the slider and the slide groove, so that the operator can easily slide the slider inside the slide groove, realize the up and down movement of the annular sliding handle, and realize that the slider is easily rotated to the limit opening, reducing the labor intensity of the operation.

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 creative work are within the scope of protection of the utility model.

Embodiment 1

A ureteral catheter with a joint, the structure of which is shown in Fig. 1-Fig. 2, comprises a catheter body 1, one end of which is provided with an air bag 2, the other end of which is provided with a joint tube 6, the outer sleeve of which is provided with a sliding clamping device, the sliding clamping device comprising a first annular plate 7 fixedly connected to one end of the joint tube 6, the bottom array of the first annular plate 7 is provided with a plurality of clamping plates 9 which are arranged outside the joint tube 6, the outer walls of the plurality of clamping plates 9 are provided with a slide groove 11, the interior of the plurality of the slide grooves 11 is provided with a slider 12, the one side of the slide groove 11 is provided with a plurality of limit openings 13 in an array, the exterior of the plurality of sliders 12 is connected to the same annular sliding handle 10. The first annular plate 7 and the clamping plate 9 are both made of hard plastic, and the plurality of clamping plates 9 are connected to the first annular plate 7 in an umbrella shape.

After the urinary catheter body 1 is inserted into the patient's body and fixed, the joint tube 6 is sleeved with the urinary catheter on the urine bag. The joint tube 6 has a certain elasticity and can be stretched open, and the urinary catheter has a little strength. The urinary catheter and the joint tube 6 are adapted in size. The joint tube 6 is stretched open and sleeved on the urinary catheter, and then the annular sliding handle 10 is pulled downward to make the clamping plate 9 bear force and be pressed against the outer wall of the joint tube 6. The clamping plate 9 has a certain deformation ability. Multiple clamping plates 9 are arranged in an umbrella shape. When the annular sliding handle 10 is pulled downward, the clamping plate 9 can be pressed toward the joint tube 6, increasing the pressure between the joint tube 6 and the urinary catheter, indirectly increasing the friction, avoiding the joint tube 6 and the urinary catheter from being hooked, avoiding pain for the patient and reducing the labor intensity of the nurses;

Then, by rotating the annular sliding handle 10, the slider 12 is moved into the limiting opening 13, so that the slider 12 can be prevented from moving upward, resulting in the inability of the pressing plate 9 to effectively press the connection between the joint pipe 6 and the urinary catheter. The surface of the slider 12 abutting against the chute 11 is provided with a ball, and the side of the pressing plate 9 close to the joint pipe 6 is provided with a rubber layer.

The slider 12 moves inside the slide groove 11 through the ball bearing, which can reduce the friction between the slider 12 and the slide groove 11, so that the operator can easily slide the slider 12 inside the slide groove 11 to achieve the problem of up and down movement of the annular sliding handle 10, and realize that the slider 12 is easily rotated into the limit opening 13, reducing the labor intensity of the operation. The rotatable ball bearing is arranged at the end of the slider 12 is a prior art, so it is not shown too much in the drawings;

Since the side of the clamping plate 9 close to the joint pipe 6 needs to abut against the joint pipe 6, a rubber layer is provided on the side of the clamping plate 9 close to the joint pipe 6 to avoid direct abutment between the clamping plate 9 and the joint pipe 6. The rubber layer not only increases the friction force, but also avoids the clamping plate 9 from damaging the tank wall of the joint pipe 6, thereby extending the service life of the joint pipe 6.

A second annular plate 8 is disposed at one end of the joint pipe 6 away from the first annular plate 7 .

Because the joint tube 6 is made of natural rubber, silicone rubber or polyvinyl chloride, the end thereof away from the first annular plate 7 is normally flexible. When the joint tube 6 is sleeved with the urinary catheter, the joint tube 6 needs to be fully opened. By setting the second annular plate 8, a certain support can be provided so that the end of the joint tube 6 that needs to be sleeved is always round, which is convenient for the operator to perform the sleeve work.

The catheter body 1 includes an inner tube and an outer tube, the inner tube is sleeved inside the outer tube, the airbag 2 has a channel in the middle, one end of the channel is connected to a urine inlet head 4, the urine inlet head 4 is provided with a urine inlet hole 5, the other end of the channel is the same as the joint tube 6 through the channel inside the inner tube, an airway is provided between the outer tube and the inner tube, an injection tube 3 connected to the airway is provided at one end of the outer tube close to the joint tube 6, and the airway is connected to the cavity inside the airbag 2.

When the end of the catheter body 1 with the balloon 2 is fully inserted into the patient's body, physiological saline is injected into the injection tube through a syringe to gradually expand the balloon 2, so that the catheter body 1 can be fixed in the patient's body to prevent it from falling off. The urine in the patient's body will enter the catheter body 1 through the urine inlet hole 5 on the urine inlet head 4, be transported to the connector tube 6 through the inner tube, and then enter the urine bag.

The surface of the annular sliding handle 10 is provided with anti-slip teeth 14 .

The anti-slip gear can increase the friction force when the operator rotates the annular sliding handle 10, and the annular sliding handle 10 can be quickly and effectively moved up and down and rotated left and right, further ensuring that the clamping plate 9 completely presses the connecting tube 6 against the urinary catheter to avoid slipping between the connecting tube 6 and the urinary catheter.

Embodiment 2

On the basis of the first embodiment, the diameter of the joint pipe 6 gradually increases from one end of the first annular plate 7 toward one end of the second annular plate 8 .

The trumpet-shaped connector tube 6 has a diameter at one end with the second annular plate 8 that is larger than the diameter of the first annular plate 7. When the connector tube 6 and the urinary catheter are sleeved together, the urinary catheter can be quickly inserted into the connector tube 6, and then the urinary catheter is further inserted into the connector tube 6 until it is inserted to the maximum extent. The connector tube 6 has a certain elasticity and is fully stretched and sleeved on the urinary catheter, which can prevent urine from leaking from the gap between the connector tube 6 and the urinary catheter. Then, a plurality of clamping plates 9 are used to increase the pressure when the connector tube 6 contacts the urinary catheter, so as to prevent the connector tube 6 and the urinary catheter from being hooked and detached.

The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions, or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
