Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an intra-abdominal pressure monitoring device. Background Art

[0002] Intra-abdominal pressure (IAP) refers to the intrinsic pressure in the abdominal cavity, which is mainly generated by the hydrostatic pressure of the abdominal organs. The gastrointestinal tract is one of the organs most sensitive to increased intra-abdominal pressure. Increased volume of body cavity organs, increased body fluids, and the use of ventilators are all factors that lead to increased intra-abdominal pressure. Intra-abdominal pressure monitoring can be divided into direct measurement and indirect measurement according to the monitoring method. The measurement methods of intra-abdominal pressure are divided into direct measurement and indirect measurement. The direct measurement method refers to the pressure measurement through the abdominal drainage tube or the sensor connected to the puncture needle. The pressure measurement value is relatively accurate, but this method is somewhat traumatic. The abdominal cavity conditions of most patients are relatively complicated, so this method is rarely used clinically. The indirect measurement method reflects the abdominal pressure by measuring the pressure of abdominal distension. Among them, the intra-bladder pressure can objectively reflect the intra-abdominal pressure, has the advantages of simple operation and less trauma, and is often used clinically. The method is that the patient lies flat, and under aseptic operation, a special catheter is inserted into the bladder through the urethra. After the bladder is empty, the tee is adjusted to allow about 50-100mL of sterile saline to be injected into the bladder through the catheter. The catheter is then clamped and the tee is adjusted to allow the catheter to connect to the atmosphere. The pubic symphysis is used as the zero point, and the height of the water column is measured as the intra-abdominal pressure measurement value.

[0003] In clinical practice, there is no dedicated connecting tube for monitoring intra-abdominal pressure. Multiple hoses are connected by direct plugging and unplugging, relying on the friction between the inner wall of the connecting tube and the outer wall of the hose to achieve connection and retention, which increases the workload of nursing staff. Moreover, this connection method is not only time-consuming and labor-intensive, inconvenient to use, and increases the possibility of abdominal infection, but also prone to leakage at the joints of components, polluting the environment.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] The intra-abdominal pressure monitoring method is that the patient lies flat, and under aseptic operation, a special catheter is inserted into the bladder through the urethra. After the bladder is emptied, the tee is adjusted to allow approximately 50-100 mL of sterile saline to be injected into the bladder through the catheter. The catheter is then clamped and the tee is adjusted to allow the catheter to connect to the atmosphere. The pubic symphysis is used as the zero point, and the height of the water column is measured as the intra-abdominal pressure measurement value.

[0038] In the related art, when monitoring intra-abdominal pressure, the operator connects multiple hoses by directly plugging and unplugging, draws a certain amount of saline with a syringe, injects the saline into the connecting tube, first connects the catheter to the urine bag to drain the urine in the bladder, and then connects the catheter to the assembled connecting tube. This is relatively complicated and the sealing of the connection cannot be guaranteed.

[0039] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an intra-abdominal pressure monitoring device. When the hose 16 needs to be connected to the connecting pipe 12, the operator only needs to align the connecting pipe 12 with the sleeve 21 and rotate the sleeve 21. The internal thread 22 on the inner wall of the sleeve 21 is threadedly connected with the external thread 23 on the outside of the connecting pipe 12, so that when the sleeve 21 rotates, the connecting pipe 12 is gradually screwed into the sleeve 21 until the connecting pipe 12 is fitted with the hose 16, completing the connection of the hose 16. The baffle 24 prevents the hose 16 from detaching downward from the sleeve 21, which is convenient and quick.

[0040] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0041] Combination Figure 1-Figure 4The embodiment of the present application provides an intra-abdominal pressure monitoring device, including a main body component 1, wherein the main body component 1 includes: a pipe 12 is provided at the bottom output end of a three-way connector 11, a pipe 2 13 is provided at the output end of one side of the three-way connector 11, a syringe 14 is provided at the other end of the pipe 2 13, a detection tube 15 is provided at the top of the three-way connector 11, a connecting component 2 is provided at the bottom of the pipe 12, and the pipe 12 is connected to a hose 16 through the connecting component 2, and the connecting component 2 includes: a sleeve 21 is sleeved at the bottom of the pipe 12, an internal thread 22 is provided on the inner wall of the sleeve 21, an external thread 23 is provided on the outer wall of the pipe 12, and cooperates with the internal thread 22, a baffle 24 is provided at the bottom of the sleeve 21, and the hose 16 slides between the baffles 24.

[0042] When it is necessary to monitor the intra-abdominal pressure of the patient, the patient is first laid flat, the operator draws physiological saline from the syringe 14, and then connects the syringe 14 to the second connecting pipe 13, and connects the hose 16 to the bottom of the connecting pipe 12 through the connecting assembly 2: the top of the hose 16 is in the sleeve 21, the operator aligns the connecting pipe 12 with the sleeve 21, rotates the sleeve 21, and the internal thread 22 of the inner wall of the sleeve 21 is threadedly connected with the external thread 23 on the outside of the connecting pipe 12, so that when the sleeve 21 rotates, the connecting pipe 12 is gradually screwed into the sleeve 21 until the connecting pipe 12 is fitted with the hose 16, and the connection of the hose 16 is completed, and the baffle 24 prevents the hose 16 from falling out of the sleeve 21. After the hose 16 is connected to the pipe 12, the bottom of the hose 16 is connected to the catheter bag (not shown in the figure), and then the three-way joint 11 is rotated to make the pipe 2 13 and the inner cavity of the hose 16 communicate with each other. The operator pushes the syringe 14 to move. When the saline in the syringe 14 moves, the gas in the hose 16 and the catheter is discharged. Then the catheter is clamped and the saline is quickly pushed in. Then the three-way joint 11 is rotated to make the hose 16 communicate with the inner cavity of the detection tube 15. The pressure in the patient's abdominal cavity pushes the saline to move upward. The detection tube 15 uses the pubic symphysis as the zero point. The height of the water column in the detection tube 15 is the intra-abdominal pressure measurement value.

[0043] Specifically, the hose 16 can rotate in the sleeve 21, so when the sleeve 21 rotates to connect with the pipe 12, the hose 16 does not need to rotate, so as to prevent the hose 16 from twisting. The three-way connector 11 is a liquid gate or a rotary plug, which is used to control the flow of liquid in the lumen, and can be used to infuse two or more drugs at the same time, and the drug administration can also be started or stopped by adjusting the switch of the three-way connector 11. It consists of a three-way body, a switch, a male Luer port and two female Luer ports. Each of the two female Luer ports has a one-way valve. By controlling the switch, the flow direction of the liquid in the three-way connector is controlled. All three ports are covered with sterile protective caps.

[0044] In some embodiments, the outer wall of the detection tube 15 is provided with a scale, which facilitates the operator to accurately obtain the intra-abdominal pressure data.

[0045] In some embodiments, a sealing ring 25 is provided on the top of the hose 16. The cross-section of the sealing ring 25 is in an inner eight-shaped shape. When the bottom end of the connecting pipe 12 enters the sleeve 21, the sealing ring 25 will be squeezed, and the sealing ring 25 will seal the connection between the connecting pipe 12 and the hose 16.

[0046] In some embodiments, a protrusion 26 is provided on the outer wall of the hose 16, and a spring 261 is provided on the side of the protrusion 26 close to the baffle 24. The protrusion 26 prevents the hose 16 from slipping out of the bottom of the sleeve 21. When the connecting pipe 12 gradually enters the sleeve 21, the spring 261 is gradually compressed to ensure the seal between the connecting pipe 12 and the hose 16.

[0047] In some embodiments, an elastic sheet 27 is provided on the inner wall of the sleeve 21 through a torsion spring. The inclination direction of the elastic sheet 27 is the same as that of the sealing ring 25. The elastic sheet 27 can be folded downward and cannot move upward, so that the protrusion 26 on the outer wall of the hose 16 cannot pass through the area above the elastic sheet 27, which is used to limit the movement of the hose 16 and prevent the hose 16 from detaching from the sleeve 21 from above.

[0048] In some embodiments, the length of the external thread 23 is greater than the length of the internal thread 22 , thereby increasing the firmness of the connection between the connecting pipe 12 and the hose 16 .

[0049] In some embodiments, a filter 151 is provided on the top of the detection tube 15 to prevent dust from entering the detection tube 15 that is connected to the atmosphere, making it inconvenient to clean.

[0050] In some embodiments, the syringe 14 is sealed to the second connecting pipe 13 to prevent saline from flowing out from the interface between the syringe 14 and the second connecting pipe 13 to affect the use effect of the device.
