Description

Technical Field

[0001] The present application relates to a medical device, and in particular to a bladder flushing bracket. Background Art

[0002] Patients with prostate hyperplasia in urology currently use 3000ml sodium chloride solution for continuous bladder irrigation after surgery. Patients need to record the amount of inflow and outflow, and the amount of inflow and outflow should be as accurate as possible. Since the 3000ml sodium chloride solution bag is a thin film plastic bag, although the scale is marked on it, the 3000ml sodium chloride solution bag is hung at the upper end. As the irrigation progresses, the liquid in the bag decreases, and the filling degree of the bag will also change greatly. This causes the volume of the liquid at the same scale to have a large deviation when the filling degree of the bag is different.

[0003] In addition, there are also requirements for the flushing height of sodium chloride solution. Generally, the height difference between the liquid surface and the patient's bed surface is 40-60cm. If the height is too high, it is easy to cause high blood pressure, cerebral edema, and pulmonary edema in patients; if the height is too low, the flushing pressure is small, and it is impossible to flush out blood clots in the bladder, that is, residual prostate tissue fragments. The height of a 3000ml sodium chloride solution bag is relatively large, generally 30cm, which causes the liquid level to drop by nearly 30cm during the flushing process. As the liquid level drops, the height difference between the liquid surface and the bed surface changes greatly, and it is easy to make the height difference not within the range of 40-60cm. Utility Model Content

[0004] In view of the above problems, the present application aims to provide a bladder flushing bracket, which, on the one hand, will not cause a significant change in the distance between the liquid surface and the bed surface due to the reduction of liquid; on the other hand, it is easy to estimate the amount of remaining liquid more accurately.

[0005] The bladder flushing bracket of the present application comprises: a base, a middle insertion rod, and a sodium chloride solution bag storage box;

[0006] A first insert is formed on the upper side of the base; a threaded hole is formed on the upper portion of the first insert for mounting a bolt;

[0007] The lower end of the middle plug rod is inserted into the first plug tube, and the end of the bolt abuts against the outer peripheral surface of the lower end of the middle plug rod, thereby fixing the middle plug rod to the upper end of the first plug tube; the upper end of the middle plug rod forms a second plug tube; a solenoid spring is arranged in the second plug tube;

[0008] The sodium chloride solution bag storage box is formed as a transparent plastic box, and a storage space is formed in the middle of the sodium chloride solution bag storage box for accommodating a 3000ml sodium chloride solution bag; an opening is formed at the upper end of the sodium chloride solution bag storage box for placing a 3000ml sodium chloride solution bag used for bladder irrigation into the storage space through the opening; two through holes are formed at the bottom of the sodium chloride solution bag storage box for passing the tubular interfaces on both sides of the 3000ml sodium chloride solution bag in the storage space out to the lower part; an upper insertion rod is formed at the center position of the bottom of the sodium chloride solution bag storage box extending downward; the lower end of the upper insertion rod is vertically inserted into the second insertion tube and rests on the solenoid spring.

[0009] Preferably, the shape of the storage space of the sodium chloride solution bag storage box corresponds to the shape of a 3000 ml sodium chloride solution bag, so that the 3000 ml sodium chloride solution bag placed therein is restricted to a prescribed shape by the sodium chloride solution bag storage box.

[0010] Preferably, an annular protrusion is formed in the middle of the middle insertion rod, and the protrusion is used to align with the bed surface where the subject is located; when a whole bag of 3000ml sodium chloride solution is placed in the sodium chloride solution bag storage box, the distance between the sodium chloride solution surface and the annular protrusion is 50cm.

[0011] Preferably, the upper end of the second insert tube extends inwardly to form a stop edge;

[0012] The lower end of the upper plug rod forms a cylindrical stopper; the diameter of the cylindrical stopper is greater than the diameter of the upper plug rod; the cylindrical stopper is supported on the upper end of the solenoid spring.

[0013] The bladder flushing bracket of the present application limits the shape of the 3000ml sodium chloride solution bag through the sodium chloride solution bag holding box, so that the sodium chloride solution bag contained therein has a relatively stable shape, which is convenient for more accurate measurement of the amount of remaining liquid; the bladder flushing bracket of the present application restores its length as the liquid decreases through the solenoid spring, and can compensate for the drop in liquid level caused by the reduction in liquid, so that the height difference between the liquid surface and the bed surface can be within an appropriate range.

[0022] The bladder flushing bracket of the present application is described in detail below with reference to the accompanying drawings.

[0023] The bladder flushing bracket of the present application comprises: a base 10 , a middle insertion rod 20 , and a sodium chloride solution bag accommodating box 30 .

[0024] A first inserting tube 11 is formed on the upper side of the base 10 ; a threaded hole 12 is formed on the upper portion of the first inserting tube 11 for installing a bolt.

[0025] The lower end of the middle plug rod 20 is inserted into the first plug tube 11, and the end of the bolt abuts against the outer peripheral surface of the lower end of the middle plug rod 20, thereby fixing the middle plug rod 20 to the upper end of the first plug tube; the height of the entire bracket can be adjusted by adjusting the depth of the middle plug rod 20 inserted into the first plug tube 11. The upper end of the middle plug rod 20 forms a second plug tube 21; a solenoid spring 40 is arranged in the second plug tube 21. Because the weight of a 3000ml sodium chloride solution bag is 3kg, the liquid level will drop by 30cm after a whole bag of sodium chloride solution is transfused, so the stiffness coefficient of the solenoid spring 40 is preferably 97.7. In this way, the distance the liquid level drops is roughly the same as the distance the spring recovers, and the distance between the liquid level and the bed surface is relatively stable.

[0026] The sodium chloride solution bag storage box 30 is formed as a transparent plastic box, and the outside of the box can be marked with standard volume scale lines, so that the volume of the remaining liquid can be easily read. A storage space 31 is formed in the middle of the sodium chloride solution bag storage box 30 for accommodating a 3000ml sodium chloride solution bag; the shape of the storage space 31 of the sodium chloride solution bag storage box 30 corresponds to the shape of the 3000ml sodium chloride solution bag, so that the 3000ml sodium chloride solution bag placed therein is restricted to a specified shape by the sodium chloride solution bag storage box, which is similar to pouring the sodium chloride solution bag into a bottle, so that the actual volume number corresponding to the volume scale lines is relatively accurate. An opening is formed at the upper end of the sodium chloride solution bag storage box, which is used to place a 3000ml sodium chloride solution bag used for bladder irrigation into the storage space through the opening; two through holes 34a and 34b are formed at the bottom of the sodium chloride solution bag storage box 30, which are used to pass the tubular interfaces on both sides of the 3000ml sodium chloride solution bag in the storage space out to the lower part; an upper insertion rod 32 is formed at the center position of the bottom of the sodium chloride solution bag storage box 30 and extends downward; the lower end of the upper insertion rod 32 is vertically inserted into the second insertion tube 21 and abuts against the solenoid spring 40.

[0027] An annular protrusion 23 is formed in the middle of the middle plug rod 20. The protrusion 23 is used to align with the bed surface where the subject is located, and serves as a bed surface height indicator to facilitate determination of the distance between the bed surface and the liquid surface. When a whole bag of 3000ml sodium chloride solution is placed in the sodium chloride solution bag storage box 30, the distance between the liquid surface and the annular protrusion is 50cm.

[0028] The upper end of the second plug tube extends inward to form a stop edge 22; the lower end of the upper plug rod 32 forms a cylindrical stop head 33; the diameter of the cylindrical stop head 33 is larger than the diameter of the upper plug rod 32; the cylindrical stop head 33 is supported on the upper end of the solenoid spring 40.

[0029] When in use, first adjust the depth of the lower end of the middle plug rod inserted into the first plug tube of the base so that the annular protrusion of the middle plug rod is flush with the bed surface; then put the 3000ml sodium chloride solution bag into the sodium chloride solution bag storage box, and the distance between the liquid surface and the bed surface is 50cm. As the liquid decreases, the liquid level drops; however, as the liquid decreases, the pressure on the spiral coil spring decreases, and the spiral coil spring recovers a certain length, compensating for the distance of the liquid level drop. As a result, the distance between the liquid surface and the bed surface is relatively stable, and the distance between the liquid surface and the bed surface will not change significantly due to the reduction of liquid. Since the 3000ml sodium chloride solution bag is placed in the sodium chloride solution bag storage box, the shape is specified, so the remaining amount of liquid can be estimated relatively accurately by the volume scale on the surface of the sodium chloride solution bag storage box.
