Description

TECHNICAL FIELD

[0001] The present application belongs to the field of medical supplies, and particularly relates to a drainage liquid storage device. BACKGROUND

[0002] In clinical practice, for patients who cannot urinate by themselves or need to drain blood and fluid accumulation before and after surgery, a bag for receiving drainage liquid is needed. During operation, one end of the drainage tube is connected to the patient, and the other end is connected to the drainage bag. The drainage tube and the drainage bag are used to drain various types of fluid accumulation from the patient out of the body.

[0003] For some postoperative patients in neurosurgery (such as patients with high intracranial pressure who need to be treated with diuretics to reduce intracranial pressure, and postoperative patients with pituitary tumor who need to prevent diabetes insipidus), the amount of drainage liquid needs to be recorded. The amount of drainage needs to be accurately recorded to observe the effect of medication and evaluate the efficacy. The amount of drainage is used to adjust the medication and treatment plan. Electrolytes also need to be supplemented according to the amount of drainage, combined with other drainage conditions, to determine the amount of fluid replacement.

[0004] Currently, the scale drainage bag commonly used in clinical practice is made of soft material. Although it has scale lines, the soft material will deform as the amount of liquid increases. Therefore, after containing the drainage liquid, the data value of the amount of drainage (i.e. the volume of the amount of drainage) cannot be accurately obtained. Therefore, it is often necessary for nursing staff to use a measuring cup to pour out the liquid in the drainage bag, and then use the scale on the measuring cup to make a second measurement, in order to obtain the accurate data value of the amount of drainage.

[0005] Moreover, when the patient has too much drainage, the conventional drainage bag does not have a reminder function and is easily overlooked. Even when the patient has an abnormal condition, the conventional drainage bag cannot remind medical staff to take emergency measures.

[0006] In summary, using the conventional drainage bag, the data value of the amount of drainage cannot be quickly and accurately obtained, and the second measurement by the measuring cup greatly increases the workload of the nursing staff. Moreover, during the drainage process, the nursing staff needs to constantly monitor the drainage condition of the patient. If they are slightly negligent, they may not be able to discover the abnormal drainage condition in time. SUMMARY

[0007] The present application aims to solve the problems existing in the prior art, and provides a drainage liquid storage device that can intuitively and accurately display the data value of the amount of drainage, and can timely remind the patient or the nursing staff to pay attention to the condition of the drainage liquid.

[0060] The embodiments of the present application are as follows:

[0061]

Embodiment I

[0062] As shown in Figure 1 and Figure 2 , the bottle body 1 and the cover body 2 are both rectangular box-shaped structures. The upper end of the bottle body 1 is an open end, and the lower end of the cover body 2 is an open end, and the open end of the cover body 2 can cover the open end of the bottle body 1.

[0063] One end of the cover body 2 is hinged to one side of the upper end surface of the bottle body 1 (for example, a soft connecting strip can be used for connection or other existing connecting members for connecting the cover body 2 and the bottle body 1 can be used), and a buckle is arranged at the other end of the cover body 2, and a clamping groove is arranged on the bottle body 1 at a position corresponding to the buckle on the cover body 2, so that the buckle can be clamped into the clamping groove to realize the closing of the cover body 2, and the buckle can be opened to open the cover body 2. The buckle and the clamping groove can adopt the existing structure, and will not be described here. Figure 1 、 Figure 2 The hinge, the buckle and the clamping groove are not drawn in the figure.

[0064] Preferably, a ring-shaped sealing groove is opened on the inner wall of the lower end of the cover body 2, and a sealing ring is arranged in the sealing groove, so that the sealing between the cover body 2 and the bottle body 1 is realized through the sealing ring after the cover body 2 covers the open end of the bottle body 1, and the drainage liquid is prevented from flowing out from between the bottle body 1 and the cover body 2 when the bottle body 1 is poured.

[0065]

Embodiment II

[0066] As Figure 3 shown, the liquid level adjusting component comprises a positioning wheel 303, a gear 302 and an adjusting rod 301. The positioning wheel 303 and the gear 302 are installed on the inner wall of the bottle body 1 through respective shafts, and the adjusting rod 301 is located between the positioning wheel 303 and the gear 302 and can move up and down relative to the positioning wheel 303 and the gear 302.

[0067] The adjusting rod 301 is a long rod structure, a rack is provided on the left side surface of the adjusting rod 301, and a plurality of teeth on the rack are arranged in sequence along the length direction of the adjusting rod 301, which can engage with the gear 302. A longitudinal groove 310 is provided on the right side surface of the adjusting rod 301, and a part of the positioning wheel 303 extends into the groove 310, as Figure 4 shown.

[0068] Two longitudinal wire mounting grooves 304 are opened on the front side surface of the adjusting rod 301, and the length direction of the wire mounting groove 304 is parallel to the length direction of the adjusting rod 301. The upper ends of the two wire mounting grooves 304 are located at the same height of the upper part of the adjusting rod 301, and the lower ends of the two wire mounting grooves 304 penetrate through the lowermost end of the adjusting rod 301 along the length direction of the adjusting rod 301.

[0069] A wire 305 is fixedly installed in each wire mounting groove 304, the uppermost ends of the two wires 305 are located at the upper ends of the wire mounting grooves 304, the lowermost ends of the two wires 305 extend out of the wire mounting grooves 304 and are located below the lower end surface of the adjusting rod 301. When the length direction of the adjusting rod 301 is perpendicular to the horizontal plane, the lowermost ends of the two wires 305 are located in the same horizontal plane, and the lowermost ends of the two wires 305 serve as two liquid level detection points of the liquid level adjusting component. The wire 305 is made of copper wire, i.e. bare copper wire without an insulating layer. The wire 305 can be installed in the wire mounting groove 304 in various existing ways, such as bonding or inlaying.

[0070] The liquid level adjusting component can be arranged on the front inner wall of the bottle body 1 or on the two side inner walls of the bottle body 1. In order to facilitate manual adjustment of the adjusting rod 301, preferably, the liquid level adjusting component is arranged on the front inner wall close to the clamping groove of the bottle body 1, and the scale line 101 of the bottle body 1 is arranged on the front outer wall, so that the adjusting rod 301 can be conveniently adjusted by opening the cover body 2.

[0071] Furthermore, the shafts of the positioning wheel 303 and gear 302 are respectively fixedly installed on the bottle wall of the bottle body 1. For example, two mounting holes can be opened on the wall of the bottle body 1, and the two shafts can be fixed in the two mounting holes with sealant, with the two shafts extending into the inner cavity of the bottle body 1. The center through holes of the positioning wheel 303 and gear 302 are respectively fitted onto the two shafts, and the center through holes of the positioning wheel 303 and gear 302 are clearance-fitted with the shafts, allowing the positioning wheel 303 and gear 302 to rotate relative to the shafts. Simultaneously, retaining rings are installed on the two shafts respectively. Figure 2 (The retaining ring is not shown in the figure.) That is, the gear 302 and the positioning wheel 303 are located between the inner wall of the bottle body 1 and the retaining ring. The distance between the retaining ring and the inner wall of the bottle body 1 is slightly greater than the thickness of the gear 302 and the positioning wheel 303. This prevents the positioning wheel 303 and the gear 302 from falling off the shaft, and does not affect the rotation of the gear 302 and the positioning wheel 303.

[0072] Specifically, the central axes of the positioning wheel 303 and gear 302 are arranged parallel to each other, and the two central axes are located at the same height on the bottle body 1. The central axes of the positioning wheel 303 and gear 302 are perpendicular to the length direction of the adjusting rod 301. The adjusting rod 301 can be inserted from top to bottom between the positioning wheel 303 and gear 302. Through the meshing of the gear 302 and the rack on the adjusting rod 301, the height of the adjusting rod 301 can be adjusted and fixed. In this way, the height of the liquid level detection point can be adjusted by adjusting the adjusting rod 301. The outer diameters of the gear 302 and the positioning wheel 303 can be the same or different.

[0073] In this invention, the gear 302 is used to help the adjusting rod 301 move up and down, and the positioning wheel 303 plays a role in positioning the adjusting rod 301 to ensure that the adjusting rod 301 will not deviate. At the same time, it ensures that the rack on the adjusting rod 301 can always mesh with the gear 302. When the adjusting rod 301 is moved, the adjusting rod 301 drives the gear 302 to rotate through the rack on its side, and the positioning wheel 303 also rotates at the same time.

[0074] The adjusting rod 301, gear 302, positioning wheel 303, and shaft are all made of hard plastic, which has good insulation properties.

[0075] Furthermore, in order to connect to the buzzer 307 and the micro battery 308 on the outside of the bottle body 1, two wiring terminals 309 are arranged parallel to each other on the upper part of the bottle wall of the bottle body 1. The two wiring terminals 309 are located at the same height on the bottle wall and above the gear 302 and the positioning wheel 303.

[0076] Specifically, the terminal 309 can be a copper column, and two terminal mounting holes are formed in the upper part of the bottle wall. Preferably, the distance between the center axes of the two terminal mounting holes is the same as the distance between the center lines of the two wire mounting grooves. The diameter of each copper column is slightly smaller than the width of the wire mounting groove. The two copper columns are fixed in the terminal mounting holes by sealant respectively. The terminal 309 penetrates the bottle wall of the bottle body 1, and the inner end of each terminal 309 extends into the inner cavity of the bottle body 1, and the outer end of each terminal 309 extends to the outside of the bottle body 1. The outer end of one terminal 309 is electrically connected to one end of the buzzer 307, the other end of the buzzer 307 is electrically connected to one end of the micro battery 308, and the other end of the micro battery 308 is electrically connected to the outer end of the other terminal 309 (the electrical connection between the terminal 309, the buzzer 307, and the micro battery 308 can be wire connection, contact connection, or welding connection, etc. Various existing electrical connection methods can be used). The inner ends of the two terminals 309 extend into the two wire mounting grooves 304 respectively and contact the two wires 305, so that the liquid level adjusting component, the buzzer 307, and the micro battery 308 are connected to form a loop, as shown in Figure 5 The wire has a certain length, so that the inner end of the terminal always maintains contact with the wire during the up and down movement of the adjusting rod.

[0077] During installation, the front side of the adjusting rod 301, which is provided with the wire mounting groove 304, is in contact with the inner wall of the bottle body 1 (i.e. the side provided with the wire mounting groove 304 faces the inner wall of the bottle body 1), and the inner ends of the two terminals 309 are inserted into the lower ends of the two wire mounting grooves 304 on the adjusting rod 301 respectively. Continue to move the adjusting rod 301 downward, so that the adjusting rod 301 enters between the gear 302 and the positioning wheel 303, thereby completing the installation of the adjusting rod 301.

[0078] Since the adjusting rod 301 is light in weight, and the terminal 309 is inserted into the wire mounting groove 304, when the adjusting rod 301 is moved to a certain height, the adjusting rod 301 can be fixed at this height by the gear 302 and the positioning wheel 303.

[0079] When in use, according to the drainage volume to be monitored, manually adjust the height of the adjusting rod 301 so that the two liquid level detection points reach the scale line 101 corresponding to the monitored drainage volume. After the drainage starts, when the two liquid level detection points (i.e. the lower ends of the two wires 305) do not contact the drainage liquid (body fluid), the two wires 305 are not connected, the circuit in which the liquid level adjusting component, the buzzer 307 and the micro battery 308 are located is disconnected, and the buzzer 307 does not sound. When the drainage liquid continuously accumulates and the liquid level rises to the two liquid level detection points, the two liquid level detection points contact the body fluid, and since the body fluid is conductive, the two liquid level detection points are connected through the body fluid, i.e. the two wires 305 are connected, and the two wire terminals 309 in contact with the two wires 305 are also connected (i.e. the two wire terminals 309 in the embodiment are connected through the wires in the embodiment), at this time, the circuit in which the liquid level adjusting component, the buzzer 307 and the micro battery 308 are located is connected, and the buzzer 307 sounds to alarm, which can effectively attract the attention of the patient or the caregiver and thus be treated in time. Figure 5

[0080] Preferably, the micro power source is a button battery, which is light and can meet the power supply of the liquid level adjusting component and the buzzer 307. The micro buzzer 307 can use an existing product, which has a sharp sound and strong penetration, and the sound source emitted by the buzzer 307 can attract the attention of the patient or the caregiver.

[0081] The highest and lowest heights that the adjusting rod 301 can adjust are designed according to the needs, for example, the lowest height to be monitored is 500 ml and the highest height to be monitored is 1500 ml, when the adjusting rod 301 is moved to the lowest point, the liquid level detection point corresponds to the 500 ml scale line 101, and when the adjusting rod 301 is moved to the highest point, the liquid level detection point corresponds to the 1500 ml scale line 101. Correspondingly, the length of the adjusting rod 301 and the installation positions of the gear 302 and the positioning wheel 303 can be designed according to the bottom area of the bottle body 1 and the highest and lowest heights to be adjusted.

[0082]

Embodiment Three

[0083] A hard annular handle 306 is arranged at the uppermost end of the adjusting rod 301.

[0084] Preferably, anti-slip lines or anti-slip particles are arranged on the annular handle 306. Through the annular handle 306, the adjusting rod 301 can be conveniently moved upward and downward.

[0085]

Embodiment Four

[0086] ​A positioning ring is arranged on the inner wall of the bottle body above the two terminal heads 309. The positioning ring is a rectangular ring, the plane of which is parallel to the horizontal plane, and its width is slightly larger than the width of the adjusting rod. The adjusting rod 301 first passes through the positioning ring and then passes through the terminal heads 309. In this way, the vertical state of the adjusting rod 301 is further ensured, and the inclination of the adjusting rod 301 during movement is avoided.

[0087] Example Five

[0088] The height of the cover body 2 is greater than the height of the upper end surface of the adjusting rod 301 when the adjusting rod 301 reaches the highest position, i.e., the height of the upper end of the adjusting rod 301 corresponding to the highest limit of the alarm. In this way, when the adjusting rod 301 moves to the highest position, the cover body 2 can still be closed, and the sealing of the bottle body 1 is realized.

[0089] Example Six

[0090] A connecting pipe mounting hole 201 is arranged in the middle of the cover body 2. A sealing ring is arranged on the inner wall of the connecting pipe mounting hole 201. After the connecting pipe 4 is inserted into the connecting pipe mounting hole 201, the height of the lower end of the connecting pipe 4 from the lower surface of the bottle body 1 can be adjusted according to the needs. In order to avoid the liquid from being mistakenly dripped onto the liquid level detection point, the lower end of the connecting pipe 4 can be extended to be close to the lower surface of the bottle body 1.

[0091] The upper end of the connecting pipe 4 is located above the cover body, and the lower end of the connecting pipe 4 is located in the inner cavity of the bottle body. A connector 401 is connected to the upper end of the connecting pipe 4. The connector 401 is a conventional anti-slip connector, which can be connected to the lower end of various clinical catheters (such as drainage tubes) and can prevent the catheter from falling off.

[0092] Preferably, a Robert clamp is arranged on the connecting pipe 4, which is located above the cover body 2. The Robert clamp can be used to control the flow of the drainage liquid and can temporarily close the connecting pipe 4.

[0093] Preferably, an anti-backflow nozzle 402 is connected to the lower end of the connecting pipe 4. The anti-backflow nozzle 402 is a duckbill-shaped structure made of silica gel. When no liquid flows out of the lower end of the connecting pipe 4, the anti-backflow nozzle 402 is closed. When liquid flows out of the lower end of the connecting pipe 4, the anti-backflow nozzle 402 is opened. In this way, the backflow of the drainage liquid in the bottle body 1 into the connecting pipe 4 is avoided. Specifically, the structure of the anti-backflow nozzle 402 can refer to the structure of the silica gel core body in the existing anti-odor sewer odor-proof floor drain, which will not be described here.

[0094] Further, an air vent 202 can also be arranged on the cover body 2 for discharging the gas in the bottle body 1 during drainage.

[0095] Example Seven

[0096] The bottle body 1 is provided with a drainage pipe 102 at the lower end, and a drainage valve 103 is arranged on the drainage pipe 102. When the drainage liquid in the bottle body 1 needs to be drained, the drainage valve 103 is opened to drain the drainage liquid, and after the drainage is completed, the drainage valve 103 is closed. After the liquid in the liquid storage bottle is poured out, the liquid storage bottle can be recycled;

[0097] The drainage pipe 102 and the drainage valve 103 can be used on the existing urine collection bag, and will not be described here.

[0098]

Example Eight

[0099] A hanging rope is arranged at the upper end of the bottle body 1, which is used to hang the liquid storage bottle on a hospital bed, or to carry the liquid storage bottle by the hanging rope.

[0100] The use method of the present application is as follows:

[0101] The cover body 2 is opened, and the scale line 101 at the height that needs to be alarmed is horizontally observed, and the height of the adjusting rod 301 is adjusted. When the liquid level detection point of the adjusting rod 301 reaches the scale line 101, the movement of the adjusting rod 301 is stopped, and then the cover body 2 is closed.

[0102] When the liquid level of the drainage liquid rises to the two liquid level detection points, the two liquid level detection points contact the body fluid. At this time, the circuit in which the liquid level adjusting part, the buzzer 307 and the micro battery 308 are located is conducted, and the buzzer 307 emits a sound to alarm. Through the alarm, the attention of the patient or the caregiver can be effectively attracted, and then timely treatment can be performed.

[0103] During drainage, if the urine drainage liquid storage bottle is used for urinary catheterization, due to the pressure of the human body itself, the urine will automatically enter the liquid storage bottle. If it is used for drainage of other liquids, negative pressure is needed. A negative pressure ball can be connected between the drainage tube and the connecting tube to guide the liquid into the liquid storage bottle by the negative pressure ball. These are mature operation methods in the clinic, and will not be described here.
