Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a bladder pressure measuring device. Background Technology
[0002] Simple bladder capacity and pressure measurement is used in hospitals to assess patients with neurogenic bladder. Currently, it mainly uses a manometry scale, a Y-shaped three-way valve, a manometry tube (usually replaced by a disposable suction catheter or oxygen tubing), and an infusion set. However, the manometry tube has no graduations, requiring a separate manometry scale, which is inconvenient. The measurement process also requires the use of a special measuring ruler, increasing the number of steps, affecting work efficiency and the accuracy of readings, and increasing departmental costs.

[0020] 1. This utility model proposes a bladder pressure monitoring device, including a fluid inlet device, which includes an inlet tube. One end of the inlet tube is connected to a first three-way valve, which is also connected to a pressure monitoring device and an infusion device. The infusion device includes an infusion tube, and the pressure monitoring device includes a pressure monitoring tube with graduations. During pressure measurement, the zero mark of the pressure monitoring tube is aligned with the level of the patient's pubic symphysis.

One end of the intubation tube is connected to the patient's bladder, and the end of the intubation tube entering the patient's bladder is connected to an intubation tip. The end of the intubation tip away from the intubation tube has an arc-shaped structure, making it easier for the intubation tube to enter the body and reducing discomfort.

Detailed Implementation
[0031] The following is combined Figures 1 to 3 This utility model will be described in detail.
[0032] This embodiment provides a bladder pressure measurement device, such as... Figure 1 and Figure 2As shown, the device includes a fluid inlet device, which includes an inlet pipe 10, one end of which is connected to a first three-way connector 20; a pressure measuring device, which includes a pressure measuring tube 30 connected to the first three-way connector 20, the side wall of which is decorated with graduation marks and has a built-in float 301; and an infusion device, which includes an infusion tube 40, which is connected to the inlet pipe 10 and the pressure measuring tube 30 through the first three-way connector 20. Before the fluid enters the pressure measuring tube 30, the center of the float 301 is coplanar with the zero mark of the pressure measuring tube 30, and the float 301 does not affect the reflux of saline into the pressure measuring tube 30. When measuring the pressure in a patient's bladder, the infusion device is placed on an infusion stand. After the patient has urinated, the infusion tube 10 is connected to the saline solution in the infusion device. The pressure measuring tube 30 is adjusted before measurement. When the pressure measuring tube 30 is adjusted, its zero mark is on the same horizontal plane as the patient's pubic symphysis, and the center of the float 301 is coplanar with the zero mark. As saline solution continuously enters the patient's bladder, it flows back into the pressure measuring tube 30. The pressure of the saline solution acts on the float 301, and the buoyancy and pressure balance, allowing the float 301 to float in the saline solution and maintain a stable position. By measuring the equilibrium position between the float 301 and the liquid in the pressure measuring tube 30, i.e., reading the scale indicated by the float 301, the pressure within the bladder can be determined. As the water level inside the pressure measuring tube 30 rises, the position of the float 301 changes accordingly. The pressure value indicated by the scale line on the float 301 corresponds to the pressure value inside the patient's bladder. Observing the position of the float 301 facilitates the observation of the bladder pressure value. Measurement is stopped when the liquid in the pressure measuring tube 30 rises above the scale mark or when there is leakage from the urethra. In some embodiments, the surface of the float 301 is a bright color such as red to facilitate reading; the float 301 can also be replaced with floats of other shapes. The float 301 is made of a lightweight material, and the resulting error is negligible. In some embodiments, the scale mark on the pressure measuring tube 30 corresponding to the float 301 can be calibrated before use.
[0033] In this embodiment, a laser locator 302 is provided on the pressure measuring tube 30. The laser emission port of the laser locator 302 and the zero mark on the scale are on the same horizontal plane. Adjusting the position of the pressure measuring tube 30 by visually estimating the pubic bone can easily lead to errors. The laser locator 302 allows for more precise positioning and reduces errors. The laser locator 302 is detachably connected to the pressure measuring tube 30 and can be reused.
[0034] In this embodiment, the infusion tube 40 is also connected to an intubation tube 50. One end of the intubation tube 50 is connected to the patient's bladder, and the end of the intubation tube 50 that enters the bladder is connected to an intubation tip 501, such as... Figure 3As shown, the end face of the inlet end 501 away from the inlet tube 50 is an arc-shaped structure, and multiple liquid inlets and outlets 5011 are arranged in a ring on the inlet end 501. Each liquid inlet and outlet 5011 is connected to the inlet tube 50, which improves the pressure measurement speed and the drainage speed, thereby increasing work efficiency. The end of the pressure measuring tube 30 away from the first tee tube 20 is also connected to a toggle cap 303. When pressure measurement is not performed, the toggle cap 303 can protect the end of the pressure measuring tube 30 from external contamination or damage, keeping the inside of the tube clean. During pressure measurement, physiological saline enters the bladder. After opening the toggle cap 303 and adjusting the position of the pressure measuring tube 30, the physiological saline is at the zero mark inside the pressure measuring tube 30.
[0035] In this embodiment, the infusion tube 50 and the infusion tube 40 are connected by a second three-way connector 60. The second three-way connector 60 is connected to a urinary catheter 70, and the other end of the urinary catheter 70 is connected to a drainage bag 80 for collecting urine discharged from the bladder after pressure measurement. A valve switch 701 is provided between the urinary catheter 70 and the drainage bag 80 and the second three-way connector 60. During pressure measurement, the valve switch 701 is closed, and the saline solution does not enter the urinary catheter 70 but instead enters the patient's bladder and the pressure measurement tube 30. After pressure measurement, the valve switch 701 is opened, and the liquid does not enter the first three-way connector 20 but instead enters the drainage bag 80 through the urinary catheter 70.
[0036] In this embodiment, a puncture needle 90 is provided at one end of the infusion tube 10 near the infusion device to puncture the infusion bag and other infusion devices to complete the infusion. A dropper 100 is also provided on the infusion tube 10. The design of the dropper 100 helps reduce air bubbles in the infusion tube 40, preventing air bubbles from entering the patient's bladder and affecting measurement results. A flow regulator 110 is sequentially provided on the infusion tube 10. Since different patients require different infusion rates, the flow regulator 110 can adapt to these different needs and provide personalized infusion rates. In some embodiments, the dropper 100 is located between the puncture needle 90 and the flow regulator 110.
[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
