Description

A Simple Device for Measuring Bladder Volume and Pressure

technical field

The utility model relates to the field of medical appliances, in particular to a simple bladder capacity and pressure measuring device.

Background technique

Due to the different planes and degrees of spinal cord injury in patients with neurogenic bladder, the types of bladder dysfunction are also different. Different types of bladder, clinical treatment and nursing measures are also different, and sometimes the treatment measures are even completely opposite. Therefore, before dealing with neurogenic bladder, it is necessary to understand the type of bladder dysfunction in the patient, so that targeted measures can be taken to improve and restore the bladder function of the patient.

Chinese patent CN2011201812183 discloses a simple bladder pressure measuring device, including an infusion dropper and a liquid storage bottle. The infusion dropper is composed of an infusion bottle plug, an upper dropper, a Mohs dropper and a lower dropper. The liquid outlet is respectively connected with the liquid outlet of the infusion bottle plug and the liquid inlet of the Mohs dripping pot, the liquid outlet of the Mohs dripping pot is connected with the liquid inlet of the lower dropper, and the upper liquid outlet of the lower dropper The catheter connector is connected, and the infusion bottle plug of the infusion dropper is plugged and communicated with the bottle mouth of the liquid storage bottle.

Chinese patent CN2010201647124 discloses an electronic bladder manometer, including an infusion bottle and a conduit connected to the infusion bottle, a control switch is provided on the conduit, and a pressure gauge for monitoring bladder pressure is installed on the outer wall of the free end of the conduit. The signal output end of the pressure sensor is electrically connected with an information processing display module; the free end of the catheter is inserted into the patient's urethra, the control switch is turned on, and the pressure measuring fluid in the infusion bottle is poured into the bladder. When hydraulic fluid is pressed, the control switch is turned off, and the value displayed on the information processing display module at this time is the bladder pressure.

However, the existing bladder manometers are either expensive or inconvenient to operate.

Utility model content

The purpose of the utility model is to provide a device that can easily measure bladder capacity and pressure at the same time.

In order to achieve the above object, the utility model adopts the following technical solutions: a simple bladder capacity and pressure measuring device, comprising: a heating jacket, an infusion bottle, a bladder manometry tube and a scale; the bladder manometry tube is Y-shaped, The three sections of conduits are respectively an infusion dropper, a bladder pressure indicating tube, and a urinary catheter connecting tube; the surface of the scale is provided with a draw-in groove, and the bladder pressure indicating tube is fixed on the surface of the scale through the draw-in groove; the infusion dropper The infusion bottle is connected, and the heating jacket is set on the outside of the infusion bottle.

The infusion dropper includes an infusion bottle plug, an upper dropper, a control valve, a Mohs dropper and a lower dropper and is connected in sequence, and an exhaust valve is arranged on the infusion bottle plug.

The upper end of the bladder pressure indicating tube is provided with a drainage bag communicated with atmospheric pressure.

The upper end of the scale is provided with a telescopic rod with a hook, and the lower end is provided with a laser emitter.

The heating cover includes a double-layer soft cloth cover, a heating wire and a thermostat arranged inside the double-layer soft cloth, a power cord connected to the thermostat, and adhesive sheets at both ends of the double-layer soft cloth cover.

Since saline is used in the measurement process, if the temperature of the dripped saline is inconsistent with the temperature of the human body (too high or low), it will cause abnormal stimulation to the detrusor muscle of the bladder, resulting in the premature contraction of the detrusor muscle, making the measurement results consistent with the bladder. There is a deviation in the actual functional state of the bladder, which brings wrong guidance to the judgment of the clinical bladder functional state. If the temperature of the brine is adjusted to be close to the temperature of the human body, the measurement error caused by this factor will be eliminated. The original brine temperature is heated by microwave oven and water bath method. Since it is difficult to control the heating time and the temperature after heating by these two methods, a thermostat is used to make our operation method more scientific and adjustable. Put an end to the disadvantages of the above methods to improve the reliability and accuracy of the measurement results.

During the measurement process, the different hanging heights of the piezometric tubes will cause deviations between the measured pressure value in the bladder and the actual value. If it is too high, the measured pressure will be low, and if it is too low, the measured pressure will be high. The original method is to use the visual method to adjust the 0 point of the scale so that it is at the same level as the patient's pubic symphysis. However, due to the difference in the accuracy of the visual observer and the individual visual method, the adjusted 0 point will have artificial differences. The utility model uses laser technology to correct the position of 0 o'clock, and eliminates the error caused by the difference in suspension height to the measurement result.

Different patients have different bladder pressure. When the bladder pressure exceeds the highest point of the scale, the liquid in the pressure measuring tube will rush out of the tube, causing troubles to the patient or operator. This product is equipped with an open drainage bag at the end of the pressure measuring tube to avoid the trouble caused by liquid overflow.

The pressure scale is a scalable scale, which avoids the disadvantage that the original long pole scale is not easy to carry. It brings convenience to the consultation of clinical brother departments.

The utility model is a measuring device for evaluating the functional state of the bladder. The device is simple and practical, has reliable measuring results, and can provide reference data for clinical treatment and nursing. At the same time, the infusion bottle can be heated according to the temperature in the patient's rectum, and the temperature of the liquid entering the bladder can be controlled to be close to the temperature in the rectum, so that the liquid entering the bladder can maintain a suitable temperature without irritating the bladder, and the bladder capacity and pressure can be measured at the same time.

The utility model has the advantages of simple structure and low cost, and the bladder pressure measuring tube is disposable, easy to use and low in price.
