Description

Technical Field

[0001] The utility model belongs to the technical field of medical supplies, and in particular relates to a bladder pressure measuring tube. Background Art

[0002] Surgical ICUs receive a large number of critically ill patients, many of whom have high intra-abdominal pressure, such as severe pancreatitis, multiple trauma, abdominal tumors, etc. Indirect intra-abdominal pressure monitoring, i.e. bladder pressure, is usually used to monitor intra-abdominal pressure in such patients. Monitoring intra-bladder pressure through a urinary catheter is a common method in the intensive care unit (ICU).

[0003] In clinical work, we also try to use a disposable extension tube connected to the liquid collection port of a precision urine bag to measure bladder pressure. When measuring pressure, we need to inject saline into the tube. The existing method is to inject directly into the tube through a syringe without a clamping device. When the syringe is separated, this method will cause air to enter the tube, which will cause the saline water column to be fractured during pressure measurement, making the measurement inaccurate. Whether it is a bladder irrigator or a disposable extension tube, you need to bring your own ruler to measure the height of the water column when measuring pressure. It is difficult for one person to operate and it takes a long time. Utility Model Content

[0042] The following is combined with Figure 1 to Figure 7 The utility model is further described in detail, but it is not intended to limit the utility model.

[0043] A bladder pressure measuring tube comprises a tube body 1, wherein the tube body 1 comprises a first opening 11 and a second opening 12, wherein the first opening 11 and the second opening 12 are respectively provided with a first sealing cover 13 and a second sealing cover 14, wherein the first sealing cover 13 and the second sealing cover 14 are movably connected to the first opening 11 and the second opening 12; the first opening 11 and the second opening 12 are respectively provided at two ends of the tube body 1; an isolating member 2 is provided on the tube body 1, wherein the isolating member 2 comprises an isolating body 21, a locking buckle 22 and a clamping rod 23, wherein a through hole 211 is provided on the isolating body 21, wherein the through hole 211 penetrates the isolating body 21, wherein the tube body 1 is penetrated in the through hole 211, wherein one end of the clamping rod 23 is movably connected to the isolating body 21, wherein an extrusion block 231 is provided on the clamping rod 23, wherein the extrusion block 231 is provided facing the tube body 1.

[0044] Specifically, the second opening 12 of the tube body 1 is connected to the liquid collection port of the urinary catheter or the precision urine bag, and the syringe injects harmless liquid into the tube body 1 through the first opening 11 of the tube body 1, and the liquid flows into the patient's bladder through the tube body 1 and the urine bag. The first sealing cover 13 and the second sealing cover 14 are used to seal the first opening 11 and the second opening 12 of the tube body 1 to prevent external bacteria from entering the tube body 1, thereby maintaining the tube body 1 as a sterile space and preventing bacteria from entering the patient's body to cause secondary harm to the patient. When injecting liquid into the tube body 1, the first opening 11 is connected to the syringe, and the second opening 12 is connected to the urinary catheter, so that the tube body 1 is a closed space, and the syringe At the moment of detachment from the first opening 11, the sealed space inside the tube body 1 is broken, and the liquid in the tube body 1 will flow toward the first opening 11, causing the liquid to break, resulting in inaccurate pressure measurement. Therefore, after the liquid is injected, the clamping rod 23 is moved toward the second isolation body 21, and the extrusion block 231 on the clamping rod 23 is pressed toward the tube body 1, so that the tube body 1 is divided into two spaces. At this time, when the syringe is detached from the first opening 11, the external pressure will not cause the liquid in the tube body 1 to break. At the same time, by setting a through hole 211 in the isolation member 2, the isolation member 2 can be moved along the tube body 1. The isolation member 2 can be set at any place in the tube body 1, which greatly improves the practicality of the pressure measuring tube.

[0045] In some embodiments, further, an extrusion groove 212 is provided on the isolation body 21, the extrusion groove 212 is perpendicular to the through hole 211, and the extrusion groove 212 is respectively connected with the through hole 211 and the outside, when the clamping rod 23 moves toward the isolation body 21, the extrusion block 231 is placed in the extrusion groove 212, the width of the extrusion block 231 is smaller than the width of the extrusion groove 212, and the height of the extrusion block 231 is greater than the height of the extrusion groove 212.

[0046] Specifically, in the present embodiment, the extrusion groove 212 cooperates with the extrusion block 231 to extrude the tube body 1. The width and height of the extrusion groove 212 are both greater than the extrusion block 231. One end of the clamping rod 23 is connected to the first isolation body 21. Therefore, when the clamping rod 23 moves, it drives the extrusion block 231 to move in a circular arc. Therefore, when the extrusion block 231 moves, the width of its movement trajectory is greater than the width of the extrusion block 231 itself. Setting the width of the extrusion groove 212 to be greater than the width of the extrusion block 231 can prevent the extrusion groove 212 from interfering with the extrusion block 231 when the extrusion block 231 moves into the extrusion groove 212, so that the extrusion block 231 cannot press the tube body 1.

[0047] In the present application, the height of the extrusion block 231 is greater than the height of the extrusion groove 212, so that the pressurizing groove can maximally squeeze the tube body 1, thereby dividing the tube body 1 into two spaces.

[0048] In some embodiments, a groove 213 is further provided on the isolation body 21 , a first elastic member 214 is provided in the groove 213 , and two ends of the first elastic member 214 are respectively connected to the groove 213 and the clamping rod 23 .

[0049] Specifically, a groove 213 is provided for accommodating a first elastic member 214. The first elastic member 214 is provided between the groove 213 and the clamping rod 23, and the two ends of the first elastic member 214 are fixedly connected to the groove 213 and the clamping rod 23 respectively. When the squeezing of the clamping rod 23 is abandoned, the first elastic member 214 pushes the clamping rod 23 away, so that an acute angle is formed between the clamping rod 23 and the second isolation body 21. At this time, the squeezing block 231 is separated from the squeezing groove 212, and the squeezing groove 212 no longer squeezes the tube body 1. The liquid in the tube body 1 can flow smoothly from the first opening 11 to the second opening 12.

[0050] The clamp rod 23 that is bounced open by the first elastic member 214 will not be too far away from the second isolation body 21. When the tube body 1 needs to be blocked, it can be easily operated by pushing the clamp rod 23 to block the tube body 1, and it can be operated with one hand.

[0051] In some embodiments, the isolation body 21 is circular, and a receiving groove 215 is provided on the isolation body 21, the clamping rod 23 is provided in the receiving groove 215, and the size of the receiving groove 215 matches the size of the clamping rod 23. When the clamping rod 23 is placed in the receiving groove 215, the side of the clamping rod 23 facing away from the isolation body 21 is flush with the outer edge of the isolation body 21.

[0052] Specifically, the accommodating groove 215 is used to accommodate the clamping rod 23. When in use, blind operation can be performed by simply touching the clamping rod 23 on the isolation member 2 to adjust it according to the state of the clamping rod 23. The size of the accommodating groove 215 is complementary to the size of the clamping rod 23, and the clamping rod 23 can be completely accommodated in the accommodating groove 215 to avoid the clamping rod 23 occupying position.

[0053] like Figure 7 As shown, in some embodiments, a protrusion 24 is provided on one side of the isolation body 21, the protrusion 24 is provided around the outer edge of the isolation body 21, the protrusion 24 is provided integrally with the isolation body 21, the lock buckle 22 is movably provided on the surface of the protrusion 24 perpendicular to the outer edge of the isolation body 21, and the lock buckle 22 moves toward the clamping rod 23.

[0054] Specifically, the protrusion 24 is used to set the lock buckle 22, and the lock buckle 22 is supported by the protrusion 24. At the same time, the protrusion 24 is set, so that the direction of the isolation member 2 can be distinguished by touch or vision. In actual operation, the direction of the isolation member 2 can be distinguished by touch, which is more convenient to use.

[0055] After the clamp rod 23 is placed in the accommodating cavity, the lock buckle 22 moves toward the clamp rod 23, thereby fixing the clamp rod 23 to prevent the clamp rod 23 from escaping from the accommodating groove due to the rebound force generated when the clamp rod 23 squeezes the tube body 1 and the elastic force of the first elastic member 214. The clamp rod 23 is fixed with one click by the lock buckle 22, so that the clamp rod 23 always squeezes the tube body 1.

[0056] In another state, when there is no need to squeeze the tube body 1, one end of the clamping rod 23 is placed outside the receiving groove 215, and the lock buckle 22 also moves toward the clamping rod 23, and the lock buckle 22 blocks a portion of the space of the receiving groove 215. In some cases, the clamping rod 23 receives external force, and one end of the clamping rod 23 approaches the receiving groove 215. Since the lock buckle 22 blocks a portion of the space of the receiving groove 215, the clamping rod 23 cannot be placed in the receiving groove 215, and the extrusion block 231 cannot squeeze the tube body 1, so that the tube body 1 always remains in a through state.

[0057] In some embodiments, a sliding rod 25 is arranged between the protrusion 24 and the lock buckle 22, and the lock buckle 22 is provided with a sliding groove 221. The lock buckle 22 is slidably arranged on the sliding rod 25 through the sliding groove 221, and an anti-slip portion 251 is arranged at the end of the sliding rod 25. An anti-slip groove 222 is also arranged on the side of the sliding groove 221 away from the protrusion 24. The diameter of the anti-slip portion 251 is larger than the diameter of the sliding groove 221, and the anti-slip portion 251 is placed in the anti-slip groove 222. A second elastic member 26 is also arranged between the protrusion 24 and the lock buckle 22, and the two ends of the second elastic member 26 respectively abut the lock buckle 22 and the protrusion 24, and the second elastic member 26 is sleeved on the sliding rod 25.

[0058] Specifically, the movement of the lock buckle 22 is guided by the sliding rod 25 to prevent the lock buckle 22 from deviating and failing to fix the clamping rod 23. Since a second elastic member 26 is sleeved on the sliding rod 25, the lock buckle 22 is always blocked by the second elastic member 26 for a portion of the space of the accommodating groove 215. When one end of the clamping rod 23 is placed in the accommodating groove 215, the lock buckle 22 is pressed by the second elastic member 26 to fix the clamping rod 23; when one end of the clamping rod 23 is located outside the accommodating groove 215, the lock buckle 22 is also pressed by the second elastic member 26 to block a portion of the space of the accommodating groove 215 to prevent the clamping rod 23 from being squeezed, thereby causing the squeezing block 231 to squeeze the tube body 1; only when one end of the clamping rod 23 needs to be placed in the accommodating groove 215 from the outside, the lock buckle 22 is triggered to move toward the protrusion 24 so that the lock buckle 22 no longer blocks the accommodating groove 215, and the clamping rod 23 can be placed in the accommodating groove 215.

[0059] In some embodiments, a connecting portion 15 is provided between the first sealing cover 13 and the tube body 1 and between the second sealing cover 14 and the tube body 1 , one end of the connecting portion 15 is connected to the tube body 1 , and the other end of the connecting portion 15 is connected to the first sealing cover 13 or the second sealing cover 14 .

[0060] Specifically, since the first sealing cover 13 and the second sealing cover 14 are movably connected to the tube body 1, the first sealing cover 13 and the second sealing cover 14 need to be removed during work, so the first sealing cover 13 and the second sealing cover 14 are very easy to be lost. The first sealing cover 13 and the second sealing cover 14 are provided with a connecting portion 15 to connect the tube body 1, which can prevent the first sealing cover 13 and the second sealing cover 14 from being lost.

[0061] In some embodiments, the second opening 12 is provided with a connector 121 , the second sealing cover 14 is connected to the connector 121 , and the connector 121 is tapered.

[0062] Specifically, the pressure measuring tube in the present application is used to connect to the liquid collection port on a urinary catheter or a precision urine bag. A connector 121 is provided at the second opening 12 to facilitate the connection of the tube body 1 with the urinary catheter or the liquid collection port. In the present application, the connector 121 is conical and has a small diameter and a large diameter. The large diameter of the connector 121 is fixedly connected to the tube body 1, and the small diameter of the connector 121 is connected to the urinary catheter or the liquid collection port. Setting the connector 121 to a cone can facilitate the connection of the connector 121 to openings of different sizes, thereby greatly improving the applicability of the pressure measuring tube.

[0063] In some embodiments, a scale 16 is further disposed on the surface of the tube body 1 , and the scale 16 is disposed between the first opening 11 and the second opening 12 .

[0064] Specifically, setting the scale 16 on the tube body 1 is helpful for the staff to read the pressure when measuring the patient's pressure, and is convenient for the staff to record.

[0065] The specific working process and principle of the bladder pressure measuring tube of the present application are as follows: first, the connector 121 of the bladder pressure measuring tube is connected to the urinary catheter or the liquid collection port of the precision urine bag. For the convenience of explanation, the following takes the connection of the connector 121 to the urinary catheter as an example, fills the syringe with harmless liquid, then removes the first sealing cover 13, connects the syringe to the first interface, at this time, the clamping rod 23 in the isolation member 2 is separated from the receiving groove 215, isolates the tube body 1, and the syringe injects the liquid into the tube body 1. The liquid flows into the patient's bladder through the tube body 1 and the urinary catheter. After injecting an appropriate amount of liquid, push the clamping rod 23 to make the squeezing block 231 squeeze the tube body 1, and divide the tube body 1 into two spaces. Then, the syringe is separated from the first opening 11, and the first sealing cover 13 is covered to prevent bacteria from entering the tube body 1. At this time, the abdomen of the patient will produce a certain pressure on the bladder when breathing, and the pressure received by the bladder is expressed by the height of the liquid column in the tube body 1. The reading at the lowest position of the liquid column is recorded, because the lowest position of the liquid column is the embodiment of the maximum pressure on the bladder. The bladder pressure is measured by the above.
