[0076] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0078] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0079] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0080] Reference Figures 1-10 , a constant temperature bladder flushing device, used to be installed on an infusion bag to connect an infusion tube; comprising: a housing 1, a receiving box 2, a guide ring 3, a guide plate 4, and an eccentric shaft 5;

[0081] The shell 1 is constructed in a rectangular shape, and a shell space is formed inside, and two ends of the shell 1 form docking joints 21 that enter the shell space; the docking joints 21 are connected to an infusion bag and an infusion tube, and the infusion bag contains physiological saline for flushing the bladder; specifically, a storage box 2 is arranged in the shell 1, and the storage box 2 forms a storage chamber a2 for storing physiological saline, and the storage chamber a2 is circular; more specifically, the side wall of the storage box 2 forms a liquid inlet a21 and a liquid outlet a22 that enter the storage chamber a2, and the liquid inlet a21 and the liquid outlet a22 are respectively connected to the docking joints 21 located on both sides of the shell 1; so that the physiological saline enters the storage chamber a2 from the liquid inlet a21, and then flows from the liquid outlet a22 to the infusion tube;

[0082] In an alternative solution, the diversion ring 3 is rotatably arranged in the accommodation cavity a2. The diversion ring 3 has a central axis L1, and the central axis L1 is horizontally arranged in the same plane as the central axis L2 of the accommodation cavity a2. Thus, the diversion ring 3 is eccentrically arranged with respect to the accommodation cavity a2, and the space formed between the diversion ring 3 and the accommodation cavity a2 is defined as the diversion cavity a3. Specifically, the side wall portion of the diversion ring 3 is always in contact with the inner wall of the accommodation cavity a2. Among them, both the liquid inlet portion a21 and the liquid outlet portion a22 are located on one side of the central axis L1. The eccentric shaft 5 is rotatably arranged at the bottom of the accommodation cavity a2 and protrudes from the bottom portion of the diversion ring 3. The axis L3 of the eccentric shaft 5 is collinear with the central axis L2. One side of the diversion plate 4 is fixedly arranged on the side wall of the eccentric shaft 5 and extends along the radial direction of the eccentric shaft 5 and penetrates through the diversion ring 3 into the interior of the accommodation cavity a2. The side wall of the diversion plate 4 away from the eccentric shaft 5 is in contact with the inner wall of the accommodation cavity a2. More specifically, a notch a31 for sliding cooperation with the diversion plate 4 is formed on the side wall of the diversion ring 3, and a sealing strip is arranged at the notch a31.

[0083] With the above structure, when the eccentric shaft 5 starts to rotate, it will drive the diversion plate 4 to rotate together. At this time, the physiological saline enters the diversion cavity a3 from the liquid inlet portion a21. As the diversion plate 4 rotates and the diversion ring 3 rotates eccentrically, the physiological saline in the diversion cavity a3 is diverted to the liquid outlet portion a22. Such a setting enables the active flow of the physiological saline, replacing the existing gravity infusion, reducing the requirements for the application environment, and enabling infusion without hanging the infusion bag on an infusion stand.

[0084] In another alternative solution, the surface of the outer wall of the diversion ring 3 in contact with the flushing liquid is defined as the diversion surface a32. The surface of the diversion surface a32 is concavely formed with grooves, and the grooves extend continuously in an S shape for one week on the diversion surface a32. Among them, heat conduction tubes 31 and cooling tubes 32 are embedded in the grooves. Specifically, a heat storage box 6 communicated with the heating tube and a refrigeration box 7 communicated with the cooling tube 32 are arranged in the diversion ring 3. A heat conduction agent is contained in the heat storage box 6, and a refrigerant is contained in the refrigeration box 7. A heater 61 is arranged in the heat storage box 6. Preferably, the heat conduction agent is sodium chloride solution with good heat conductivity; the refrigerant is Freon. The sodium chloride solution is heated to 50 °C by the heater 61, and the heat conduction agent is introduced into the heat conduction tubes 31 through a control system 8 arranged in the diversion ring 3, so that the heating of the physiological saline can be realized. Since the heat conductivities of the sodium chloride solution and the physiological saline are good, the physiological saline in the diversion cavity a3 can start to heat up to 36.5 °C - 38 °C. This temperature range is close to the human body temperature and will be more comfortable when entering the human bladder.

[0085] If the temperature is too high, the refrigerant is filled into the cooling tubes 32 through the control system 8 to quickly reduce the temperature in the diversion cavity a3, realizing the control of the flushing temperature.

[0086] In another embodiment, the control system 8 includes: a thermometer 80, a rotating shaft 81, a driver, a piston tube, a piston block, and a contact rod 9;

[0087] Specifically, the rotating shaft 81 is rotatably arranged on the accommodating box 2, and its end contacts the end of the eccentric shaft 5 and is coaxially arranged with the eccentric shaft 5; more specifically, a docking groove a5 is concavely formed in the end face part of the eccentric shaft 5, a convex block 811 corresponding to the docking groove a5 is convexly formed at the end part of the rotating shaft 81, a friction ring 812 is sleeved on the side wall of the convex block 811, and the side wall of the friction ring 812 is in close contact with the inner wall of the docking groove a5; a driver for driving the rotating shaft 81 to rotate is arranged outside the housing 1, and the driver is a motor sold on the market. When the driver drives the rotating shaft 81 to rotate, the eccentric shaft 5 is driven to rotate through the contact between the friction ring 812 and the inner wall of the docking groove a5 by friction;

[0088] In an alternative solution, piston tubes are respectively arranged on the side walls of the heat storage box 6 and the refrigeration box 7, and piston blocks are movably arranged in the piston tubes; wherein, the piston tube arranged on the heat storage box 6 is defined as the first piston tube 62, and the piston block moving in the first piston tube 62 is defined as the first piston block 621; the first piston block 621 is connected to the first piston tube 62 through a first elastic member 622; the first elastic member 622 is a spring, and always gives the first piston block 621 a pulling force close to the contact rod 9;

[0089] The piston tube arranged on the refrigeration box 7 is defined as the second piston tube 71, and the piston block moving in the second piston tube 71 is positioned as the second piston block 72; the second piston block 72 is connected to the second piston tube 71 through a second elastic member 73; the second elastic member 73 is a spring, and always gives the second piston block 72 a pulling force close to the contact rod 9;

[0090] A contact rod 9 is arranged on the side wall of the rotating shaft 81, and the contact rod 9 has a contact portion a9 that contacts the first piston block 621 / the second piston block 72; during operation, the rotating shaft 81 rotates eccentrically with the accommodating box 2, so the distance between the side wall of the rotating shaft 81 and the first piston block 621 / the second piston block 72 will become larger / smaller; therefore, the contact rod 9 will contact the first piston block 621 / the second piston block 72 to move; thus, piston movement is achieved;

[0091] In an alternative solution, a feed port a8 and a discharge port a81 are respectively formed in the heat storage box 6 and the refrigeration box 7; and a first one-way valve is arranged on the feed port a8, and a second one-way valve is arranged on the discharge port a81; the feed port a8 and the discharge port a81 in the heat storage box 6 are communicated with the heating pipe; the feed port a8 and the discharge port a81 in the refrigeration box 7 are communicated with the cooling pipe 32; wherein, the first one-way valve only allows liquid to flow into the feed port a8, and the second one-way valve allows the inlet liquid to flow out from the discharge port a81;

[0092] In the initial state, under the action of the first elastic member 622, the first piston block 621 always sucks the heat-conducting agent in the heat-conducting tube 31 into the heat storage box 6; under the action of the second elastic member 73, the second piston block 72 always sucks the refrigerant in the cooling tube 32 into the refrigeration box 7; it can be understood that when heating is required, the abutting rod 9 abuts against the first movable block, so that the first piston block 621 reciprocates in the first piston tube 62 to fill the heat-conducting agent into the heat-conducting tube 31; if the abutting rod 9 leaves the first piston, the heating agent in the heat-conducting tube 31 is sucked back into the liquid storage box under the action of the first elastic member 622; through the above technical solution, the heating and cooling of the physiological saline do not interfere with each other, and the stability of temperature control is improved.

[0093] In an alternative solution, a first limiting portion 623623 is formed at the end of the first piston block 621 close to the abutting rod 9; a second limiting portion 74 is formed at the end of the second piston block 72 close to the abutting rod 9; both the first limiting portion 623 and the second limiting portion 74 are formed with arc concave surfaces that abut against the abutting rod 9; the rotating shaft 81 forms a chute a91 for guiding the axial movement of the abutting rod 9; a driving member 85 for driving the abutting rod 9 to reciprocate along the chute a91 is arranged in the chute a91; specifically, a slider 92 fixedly connected to the abutting rod 9 is slidably arranged in the chute a91; the slider 92 is connected to the bottom of the chute a91 through a third elastic member 93, and the third elastic member 93 is a spring that always gives the slider 92 an elasticity away from the bottom of the chute a91; the driving member 85 is an electromagnet electrically connected to the temperature machine.

[0094] Specifically, a central processor is installed in the housing 1, and the central processor is electrically connected to the thermometer 80; the thermometer 80 transmits the detected temperature value to the central processor through an electrical signal, and the central processor analyzes whether the temperature exceeds 38.5 °C or is lower than 35 °C; if it exceeds 38.5 °C, an execution signal is transmitted to the actuator, and the actuator drives the electromagnet to generate magnetism and attract the slider 92 to move; in this way, the abutting rod 9 is docked with the second piston block 72, and at this time, cooling starts to prevent the temperature from being too high and scalding the patient; if it is lower than 35 °C, the actuator drives the heater 61 to increase the power, so that the temperature of the heat-conducting agent is increased, and further heating treatment is carried out on the physiological extension.

[0095] In another preferred embodiment, a deceleration piece 10 that abuts against the side wall of the eccentric shaft 5 is movably arranged in the guide ring 3, and the deceleration piece 10 is driven and connected by an electric push rod 11 arranged in the guide ring 3; a flow meter 12 electrically connected to the central processor is arranged on the liquid outlet portion a22.

[0096] Specifically, the flow meter 12 is used to detect the flow rate of the flushing and transmit the data to the central processing unit through an electrical signal. If the flow rate is higher than 90 drops per minute, the central processing unit will transmit the signal to the actuator, and the actuator will drive the electric push rod 11 to make the decelerating piece 10 contact the side wall of the eccentric shaft 5, thereby reducing the rotational speed of the eccentric shaft 5, while the rotational speed of the rotating shaft 81 remains unchanged. In this way, the flow rate can be controlled.

[0097] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
