Description

Technical Field

[0001] The present application belongs to the field of medical technology, and specifically relates to a disposable intra-abdominal pressure measuring device. Background Art

[0002] In clinical medicine, many patients need to measure their intra-abdominal pressure due to diseases in the abdominal cavity. However, it is not easy to measure the intra-abdominal pressure directly. Therefore, measuring the bladder pressure can indirectly and intuitively replace the measurement of intra-abdominal pressure. Some patients not only need to measure the intra-abdominal pressure, but also need to measure the urine volume to monitor changes in their condition.

[0003] For example, the patent CN208822762U provides a disposable intra-abdominal pressure detection device, in which a urinary catheter connector, an injection line and a measuring line are connected to the three-way valve. One end of the urinary catheter connector is connected to the urinary catheter, and the other end is connected to the three-way valve. The injection line includes a saline bag and an injection tube body connected to each other. One end of the injection tube body is connected to the three-way valve, and the other end is provided with a needle. The needle is inserted into the saline bag. The injection tube body is provided with a drip pot, a speed regulating valve and a closing clamp from top to bottom between the needle and the three-way valve. However, the measuring line in the above patent needs to be held in a vertical state, and is not conducive to storage. Utility Model Content

[0006] Furthermore, the measuring assembly also includes a measuring hose, one end of the measuring hose connected to the second end is provided with a first valve body, and a rubber plug is plugged into the other end of the measuring hose.

[0007] Furthermore, the rubber plug includes a base, a lifting ring and a plug, wherein the lifting ring is fixed to the upper side of the base, and the plug is fixed to the lower side of the base and plugged into the measuring hose; wherein a plurality of vents are provided on the outer wall of the plug.

[0008] Furthermore, a second valve body is provided between the needle and the first end.

[0009] Furthermore, the outer wall of the measuring hose is provided with a measuring scale.

[0010] Further, the inlet of the infusion valve is connected to the syringe.

[0011] The beneficial effects of the present application are as follows: the present application simplifies the lateral abdominal pressure device by arranging a three-way tube on a disposable measuring hose, thereby improving the convenience of abdominal pressure measurement. At the same time, the hose can be directly hung on the infusion stand to keep the hose in a vertical state. At the same time, the hose can be rolled up and stored when not in use, thereby reducing storage space and facilitating storage and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0015] like Figure 1-2 As shown, a disposable intra-abdominal pressure measuring device comprises a three-way tube 1, an infusion valve 2 and a measuring assembly 3; the first end of the three-way tube 1 is connected to a needle 4 for connecting a urinary catheter, the second end of the three-way tube 1 is connected to a liquid inlet of the measuring assembly 3; the third end of the three-way tube 1 is connected to the infusion valve 2; wherein, a rubber plug 5 for hanging is provided at the upper end of the measuring assembly 3. The rubber plug 5 in the above design can be used to plug the pipeline of the measuring assembly 3, and can be hung on the infusion stand through the plug.

[0016] The measuring assembly 3 further comprises a measuring hose 31, one end of which is connected to the second end and is provided with a first valve body 32, and a rubber plug 5 is plugged into the other end of the measuring hose 31. The measuring hose 31 can be curled and bundled, so as to be easy to carry.

[0017] The rubber plug 5 includes a base 51, a hanging ring 52 and a cannula 53. The hanging ring 52 is fixed to the upper side of the base 51, and the cannula 53 is fixed to the lower side of the base 51 and inserted into the measuring hose 31. The outer wall of the cannula 53 is provided with a plurality of vents 54. The vents 54 in the above design can make the measuring hose 31 communicate with the outside, so as to facilitate the measurement of intra-abdominal pressure.

[0018] A second valve body 41 is provided between the needle 4 and the first end, and can be used to prevent the liquid in the urine catheter from flowing back into the measuring hose 31 .

[0019] The outer wall of the measuring hose 31 is provided with a measuring scale, which is convenient for understanding the liquid level height and thus calculating the intra-abdominal pressure.

[0020] The inlet of the infusion valve 2 is connected to the syringe 6, so that the syringe 6 can be used to inject saline into the urinary catheter connected to the needle 4. In other embodiments, the urinary catheter can also be injected through an infusion set or an automatic injection device, and the injection speed of the saline solution only needs to be within a predetermined range.

[0021] Specific working steps: when in use, close the first valve body 32 and the second valve body 41, straighten the rolled hose and plug the end of the measuring hose 31 with the rubber plug 5, and ensure that part of the air hole does not enter the hose. Connect the ring 52 through a hanging rope or other device and hang it on the existing drip stand, while the measuring hose 31 is in a vertical state; connect the needle 4 to the patient's urethra through the urethra 7, then open the second valve body 41 and the infusion valve 2, inject a certain amount of physiological saline into the urethra at a certain speed through the syringe 6, then close the infusion valve 2 and open the first valve body 32 to measure the patient's intra-abdominal pressure. At this time, the medical staff manually adjusts the "0 scale" position of the measuring hose 31 up and down to make it at the horizontal position of the mid-axillary line at the ilium, and then reads the height of the liquid level in the measuring hose 31, so as to understand the patient's intra-abdominal pressure, which is more convenient and quick.

[0022] The present application simplifies the lateral abdominal pressure device by setting a three-way tube 1 on a disposable measuring hose 31, thereby improving the convenience of abdominal pressure measurement. At the same time, the hose can be directly hung on the infusion stand to keep the hose in a vertical state. At the same time, the hose can be rolled up and stored when not in use, which reduces storage space and facilitates storage and transportation.

[0023] The above description is only an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
