Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, the irrigation drainage assistance device of the present embodiment is generally used for irrigation and drainage of the bladder. The auxiliary flushing and drainage device comprises a tee body 1 and a valve core 2, wherein the valve core 2 is assembled at the center of the tee body 1. The tee body 1 includes three interfaces, i.e., a first interface, a second interface, and a third interface. The first interface and the second interface 1-2 are positioned on the same straight line, and the third interface is arranged perpendicular to the first interface and the second interface 1-2.

In the embodiment, the first interface is a catheter connector 1-1, the third interface is a drainage device connector 1-3, and the second interface 1-2 is used for connecting a flusher. As will be appreciated by those skilled in the art, in actual use, the positions of the interfaces on the tee body 1 can be adjusted as required.

The valve core 2 can rotate freely and be positioned, and the on-off and flow control of each interface of the tee body 1 are realized.

The diameters of the channels 1-4 at the contact positions of the three interfaces in the tee body 1 and the core body 2-2 are in tapered transition from large to small, as shown in figure 3. The design can be matched with the rotation of the valve core 2 in the flushing process to effectively buffer flushing liquid; during drainage, slow release can be formed to slow down the influence of suction on a patient, thereby improving the comfort of the patient in the whole flushing and drainage process.

As shown in fig. 4 to 6, the valve cartridge 2 includes a handle 2-1 and a core 2-2, and the core 2-2 is connected to the handle 2-1. The core body 2-2 is provided with three mutually communicated through holes 2-3, and the three through holes 2-3 are mutually communicated. The positions of the three through holes 2-3 correspond to the positions of the three interfaces on the tee body 1 respectively, namely, the two through holes 2-3 are positioned on the same straight line, and the other through hole 2-3 is arranged perpendicular to the two through holes 2-3.

The handle 2-1 is also composed of three handles 2-4, wherein two handles 2-4 are positioned on the same straight line, and the other handle 2-4 is vertical to the same straight line, namely, the handles are respectively corresponding to three interface positions in the tee body 1.

The surfaces of the three handles 2-4 are provided with arrow marks 2-5 pointing to three directions so as to facilitate the medical staff to quickly identify the direction and the rotation operation.

An annular groove 2-6 is formed between the handle 2-1 and the core body 2-2, and a rubber ring 2-7 is sleeved on the annular groove 2-6. The rubber rings 2-7 are fixedly arranged in the tee body 1. The rubber ring 2-7 is used for realizing the sealing between the core body 2-2 and the tee body 1, and can also support the core body 2-2, so that the rotation control of the whole valve core 2 is facilitated.

In the embodiment, the support of the core body 2-2 is arranged between the handle 2-1 and the core body 2-2, so that the occupation of the handle 2-1 on the internal space of the tee body 1 can be reduced, the structure is more stable and reliable, the support and the sealing can be realized by utilizing the rubber ring 2-7, and the continuous sealing effect is ensured. Meanwhile, the structure can ensure the rapid circulation of liquid at the center of the tee body 1, reduce the accumulation of the liquid and improve the flushing and drainage effects.

When in use, the auxiliary flushing and drainage device is horizontally placed as shown in figure 1 during flushing, the catheter joint 1-1 of the tee body 1 is connected with the catheter interface on a human body, the drainage device joint 1-3 is connected with the drainage bag, and the second interface 1-2 is connected with the flusher. The valve core is rotated 180 degrees, at this time, the catheter connector 1-1 is communicated with the second connector 1-2 (namely the flusher), and the drainage device connector 1-3 is closed. The flushing fluid flows into the catheter from the second connector 1-2 through the valve core 2 and the catheter connector 1-1 and then enters the bladder of the patient for flushing. In the operation process, the flow rate of the flushing liquid can be controlled by rotating the valve core in real time according to the actual reaction of a patient so as to adapt to the requirement of the patient.

When the injected liquid amount reaches the set dosage, the valve core is rotated by 90 degrees clockwise, at the moment, the catheter connector 1-1 is communicated with the drainage bag, and the second connector 1-2 (namely the flusher) is closed. The flushing fluid flows out of the patient body and enters the drainage bag through the catheter connector 1-1 and the drainage device connector 1-3. And the operation is resumed when the flushing is performed. So as to repeatedly realize the bladder irrigation and drainage of the patient.

In another embodiment, as shown in FIG. 7, the flow diverter adaptor 1-3 of FIG. 1 is interchangeable with the second port 1-2 (the port for the flusher). The catheter joint 1-1 of the three-way body 1 is connected with a catheter interface on a human body, the drainage device joint 1-3 is connected with a drainage bag, and the second interface 1-2 is connected with a flusher. The valve core is rotated 90 degrees anticlockwise, at the moment, the catheter connector 1-1 is communicated with the second connector 1-2 (namely the flusher), and the drainage device connector 1-3 is closed. The flushing fluid flows into the catheter joint 1-1 from the second connector 1-1 through the valve core 2 and then enters the bladder of the patient for flushing. In the operation process, the flow rate of the flushing liquid can be controlled in real time through the rotation of the valve core 2 according to the actual reaction of the patient so as to adapt to the requirement of the patient.

When the injected liquid amount reaches the set dosage, the valve core is rotated counterclockwise by 90 degrees, at the moment, the catheter connector 1-1 is communicated with the drainage device connector 1-3, and the second connector 1-2 (namely the flusher) is closed. The flushing fluid flows out of the patient body and enters the drainage bag through the catheter connector 1-1 and the drainage device connector 1-3. The operation is resumed when flushing. So as to repeatedly realize the bladder irrigation and drainage of the patient.

Embodiments the entire device should be slightly below the pubic symphysis plane of the patient during drainage, which facilitates bladder emptying during drainage.

The utility model ensures that the flushing fluid does not contact with the outside in the whole flushing and drainage process, ensures the cleanness of the flushing fluid, realizes aseptic operation, avoids infection risk, and is safe and effective; can greatly improve the bladder irrigation efficiency, can separate the injection and the extraction when the bladder irrigation is carried out, avoids the counter-current pollution, reduces the pollution to the operation environment and reduces the working strength of medical personnel.

The utility model provides a wash drainage auxiliary device, the method and the way that specifically realize this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary technical personnel of this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as with moist decorations the utility model discloses a scope of protection.
