[0040] Embodiment one

[0041] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a kind of flushing liquid temperature measuring assembly for bladder irrigation, including the temperature measuring block 1 made of heat conducting material, the temperature measuring block 1 one end is equipped with the through hole 11 for infusion tube 5 to pass through, the through hole 11 hole diameter is compatible with the outer diameter of infusion tube 5;

[0042] The temperature measuring block 1 one end surface is equipped with the blind hole 12 extending towards the through hole 11 axial direction, heat expansion medium is stored in the blind hole 12;

[0043] The temperature measuring block 1 is provided with a piston 2 for covering the opening of the blind hole 12, one end of the piston 2 is inserted into the blind hole 12 and is in sliding and sealing fit, and the other end extends out of the opening of the blind hole 12.

[0044] In the scheme, the temperature measuring block 1 made of heat-conducting material can quickly absorb the heat of the flushing liquid in the infusion tube 5, and reflect the temperature fluctuation through the volume change of the internal thermal expansion medium.

[0045] At the same time, the volume change of the thermal expansion medium drives the piston 2 to slide in the blind hole 12, and by observing the length change value of the piston 2 extending out of the blind hole 12, the temperature value of the flushing liquid in the infusion tube 5 at the temperature measuring block 1 is estimated, which assists in adjusting the heating capacity of the warmer to increase or decrease the temperature value of the flushing liquid flowing out of the heater, so that the temperature value of the flushing liquid after part of the heat is lost and flows to the vicinity of the temperature measuring block 1 is still within the preset temperature range, reducing the discomfort caused to the patient's body due to the temperature being too high or too low.

[0046] Among them, the temperature measuring block 1 can be made of copper, aluminum alloy, and heat-conducting silica gel, etc., which has high heat-conducting performance. The thermal expansion medium can be selected as ethanol, silicon oil, etc. Here, the aluminum alloy and ethanol are preferably used together. The temperature measuring block 1, the piston 2 and the thermal expansion medium form a structure similar to a thermometer, the temperature measuring block 1 corresponds to a capillary, and the thermal expansion medium corresponds to a temperature sensing medium.

[0047] In addition, ethanol is in a liquid state at a standard atmospheric pressure in the temperature range of -114℃ to 78℃, and in the normal temperature range (20℃ to 60℃), the volume changes linearly with temperature, and the calculation formula is:

[0048] V(T) = V0[1 + β(T - T0)]

[0049] V(T) is the volume of ethanol at the end temperature T;

[0050] V0 is the volume of ethanol at the initial temperature T0;

[0051] β is the thermal expansion coefficient (ethanol is about 1.1×103 / ℃, which is 3 times that of water).

[0052] Therefore, by measuring the volume of ethanol before and after temperature change, the temperature change difference can be calculated.

[0053] In the factory production stage, a standard volume of ethanol can be injected into the blind hole 12 at room temperature 25°C, the opening of the blind hole 12 is blocked by the piston 2, and the air in the sealed space between the piston 2 and the blind hole 12 is extracted, so that the end surface of the piston 2 away from the opening of the blind hole 12 is in full contact with the ethanol. The relative position of the piston 2 to the temperature measuring block 1 is recorded, or a limiting block is made on the piston 2 to limit the piston 2 from sliding further into the blind hole 12, and 25°C is taken as the minimum measurement temperature value of the temperature measuring assembly. Moreover, the side wall of the piston 2 is coated with polytetrafluoroethylene (PTFE) paint to reduce the friction between the piston 2 and the side wall of the blind hole 12.

[0054] In addition, the cross-sectional shape of the blind hole 12 is the same in all directions along the depth. That is, V(T) = S(blind hole 12 cross section) x H(piston 2 movement distance). Therefore, by measuring the length change value of the piston 2 extending out of the blind hole 12, the temperature value of the temperature of the flushing liquid in the infusion tube 5 near the temperature measuring block 1 can be calculated to assist in adjusting the heating capacity of the warmer.

[0055] In use, the infusion tube 5 is inserted through the through hole 11 with the end close to the patient's body, and the position of the temperature measuring assembly is adjusted so that the flushing liquid in the infusion tube 5 quickly enters the patient's body after passing through the temperature measuring block 1, so that the temperature measured by the temperature measuring assembly is close to the temperature of the flushing liquid received by the patient's body.

[0056] In this embodiment, a plurality of tabs 21 are arranged on the outer side wall of the end of the piston 2 away from the temperature measuring block 1, the plurality of tabs 21 are uniformly arranged in the length direction of the piston 2, and one end of the tab 21 is fixedly connected to the outer side wall of the piston 2.

[0057] An elastic sheet 22 is arranged on the side wall of the opening end of the blind hole 12 opposite to the tab 21, one end of the elastic sheet 22 is fixedly connected to the side wall of the blind hole 12, the other end extends towards the piston 2, and the end of the elastic sheet 22 facing the piston 2 is located on the movement track of the end of the tab 21 away from the piston 2.

[0058] In this scheme, the transverse dimension of the end of the piston 2 away from the temperature measuring block 1 is smaller than the transverse dimension of the end of the piston 2 facing the temperature measuring block 1, so that there is a gap between the side wall of the end of the piston 2 away from the temperature measuring block 1 and the side wall of the blind hole 12, and the tab 21 and the elastic sheet 22 are arranged in the gap, as shown in Figure 5 The plurality of tabs 21 are uniformly arranged in the length direction of the piston 2, the corresponding temperature values can be marked according to the different positions of the tabs 21 on the rod of the piston 2, the elastic sheet 22 is arranged at the opening end of the blind hole 12, and when the tab 21 just extends out of the blind hole 12 to align with the elastic sheet 22, the temperature value is the temperature value of the flushing liquid in the infusion tube 5. In order to quickly obtain the temperature of the flushing liquid.

[0059] Further, the elastic sheet 22 is made of a metal material, has a sheet shape and a certain elasticity, and in the process of the push piece 21 sliding through the elastic sheet 22, the push piece 21 first contacts and abuts against the elastic sheet 22, and with the push piece 21 moving, the elastic sheet 22 is bent to store elastic potential energy; at the instant of disengagement, the elastic sheet 22 quickly rebounds and drives the surrounding air to vibrate to form a sound wave. The reciprocating swing produces periodic vibration, and the vibration frequency can be changed by adjusting the material, thickness or fixing mode of the elastic sheet 22, so that different pitch sounds are emitted. The principle is similar to the sound generation mechanism of the reed instrument (such as a harmonica or a clarinet).

[0060] That is, the push piece 21 visually transmits information to the relevant technical personnel, and the metal sheet transmits information to the relevant technical personnel through hearing, thereby assisting in understanding the temperature change.

[0061] In the embodiment, the push piece 21 has a wedge shape, the tip of the push piece 21 extends to one side of the elastic sheet 22, and the inclined surface of the push piece 21 is located on one side of the piston 2 along the length direction.

[0062] In the scheme, as shown in Figure 5 , 6 , the push piece 21 has an inclined surface on both sides along the length direction of the piston 2. The inclined surface structure makes the bending process of the elastic sheet 22 more gradual, ensures uniform accumulation of elastic potential energy, and realizes rapid and sufficient energy release at the instant of disengagement, thereby enhancing the sound clarity.

[0063] In the embodiment, the depth size of the blind hole 12 is smaller than the length size of the piston 2.

[0064] In the scheme, by making the depth size of the blind hole 12 smaller than the length size of the piston 2, the end of the piston 2 away from the temperature measuring block 1 always extends out of the opening of the blind hole 12, thereby avoiding the problem that it is difficult to observe and measure because the piston 2 is completely embedded in the blind hole 12 during part of the stroke of the piston 2.

[0065] In the embodiment, the temperature measuring block 1 is composed of a measuring block 13 and a clamping strip 14, and the piston 2 is arranged on the measuring block 13.

[0066] The measuring block 13 and the clamping strip 14 are both provided with a semicircular groove on the two opposite planes, and the two semicircular grooves are spliced to form the through hole 11.

[0067] The two edges on the same side of the measuring block 13 and the clamping strip 14 are rotationally connected, and the rotation center line is parallel to the axis of the through hole 11, and the two edges on the other side of the measuring block 13 and the clamping strip 14 are detachably connected.

[0068] In the embodiment, as shown in Figure 3 , 4As shown, hinges or the like devices can be arranged between the measuring block 13 and the clamping strip 14, and the measuring block 13 and the clamping strip 14 are rotatably connected by the hinges, so that the measuring block 13 and the clamping strip 14 can present an open state and a closed state, so as to facilitate the installation of the temperature measuring assembly on the infusion tube 5 and the adjustment of the position of the temperature measuring assembly on the infusion tube 5. The two side surfaces on the other side of the measuring block 13 and the clamping strip 14 can be connected and fixed by selecting the way of sticking adhesive tape, which is simple and convenient to operate.

[0069] In the embodiment, the clamping strip 14 is made of a heat insulation material, and the measuring block 13 is made of a heat conduction material.

[0070] The measuring block 13 is externally sleeved with a protective shell 15, the protective shell 15 is made of a heat insulation material, and the protective shell 15 is open on the side wall opposite to the semicircular groove of the measuring block 13.

[0071] In the scheme, as shown in the figure, Figure 5 The clamping strip 14 and the protective shell 15 can be made of medical silica gel, medical polytetrafluoroethylene (PTFE) or the like, which has good heat insulation performance and can block the heat loss of the temperature measuring assembly at the corresponding infusion tube 5. The measuring block 13 is made of a heat conduction material (such as copper or aluminum), which can quickly respond to temperature changes; the open design of the protective shell 15 avoids shielding the measured object, and at the same time, the protective shell 15 reduces the influence of environmental heat radiation.

[0072] A kind of flushing fluid warming device for bladder irrigation, including the temperature measuring assembly and the heater main body 3 described above, the temperature measuring block 1 is connected between the heater main body and the rope 4, one end of the rope 4 is fixedly connected with the temperature measuring block 1, and the other end is fixedly connected with the outer wall of the heater main body.

[0073] In the scheme, as shown in the figure, Figure 1 , 2 The temperature measuring assembly and the heater main body are connected together by the rope 4, which has the purpose of preventing loss. And the temperature measuring assembly can move freely relative to the heater main body, so that the temperature measuring assembly can measure the temperature of the infusion tube 5 at a position far away from the heater main body 3, which has high flexibility.

[0074] Among them, the heater main body 3 can be selected as a medical blood transfusion infusion heater, model: QW3.

[0075] In the embodiment, a disc 31 is fixedly connected to the outer wall of the heater main body, and an annular groove is formed in the outer circular surface of the disc 31.

[0076] In the scheme, as shown in the figure, Figure 2 The annular groove is used for winding and winding the rope 4, which has the function of accommodating the rope 4, so as to facilitate the storage and transportation of the warming device.

[0077] Embodiment two

[0078] As Figure 7 shown, the difference from the first embodiment is that,

[0079] In this embodiment, the outer side wall of the piston 2 opposite to the temperature measuring block 1 is engraved with scale lines 23 arranged uniformly along the length direction of the piston 2.

[0080] In this scheme, the scale lines 23 are provided with numbers, when the numbers are located on the end face of the opening end of the blind hole 12, the numbers can be used to represent the corresponding sliding distance value of the piston 2, or can be converted into temperature value (representing the current measured irrigation fluid temperature value) for easy observation and reading.

[0081] Embodiment three

[0082] As Figure 8 shown, the difference from the first embodiment is that,

[0083] In this embodiment, the outer side wall of the piston 2 opposite to the temperature measuring block 1 is divided into three identification zones along the length direction.

[0084] In this scheme, the three identification zones are respectively painted with different patterns, or painted with different colors (such as red, yellow, green) for easy and rapid differentiation. The three identification zones are sequentially: the first identification zone 24, the second identification zone 25 and the third identification zone 26 from the bottom of the blind hole 12 to the opening direction of the blind hole 12.

[0085] The first identification zone 24: the corresponding measured temperature range is 25℃-32℃, when the projection of the edge of the opening end of the blind hole 12 on the piston 2 is located in the first identification zone 24, it indicates that the temperature of the irrigation fluid entering the patient's body is relatively low, and the heater main body 3 needs to increase the heat supply;

[0086] The second identification zone 25: the corresponding measured temperature range is 32℃-37℃, when the projection of the edge of the opening end of the blind hole 12 on the piston 2 is located in the second identification zone 25, it indicates that the temperature of the irrigation fluid entering the patient's body is relatively appropriate, and the heater main body 3 does not need to change the heat supply;

[0087] The third identification zone 26: the corresponding measured temperature range is 38℃-45℃, when the projection of the edge of the opening end of the blind hole 12 on the piston 2 is located in the third identification zone 26, it indicates that the temperature of the irrigation fluid entering the patient's body is relatively high, and the heater main body 3 needs to reduce the heat supply.

[0088] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
