Example 1
As shown in fig. 1 to 5, embodiment 1 provides a blood temperature monitor for hemodialysis, which includes a card member 1, a heat conductor 2, a temperature sensor 3, and a temperature monitor 4.
The clamping piece 1 is a plastic piece and is a base body for fixing the heat conduction piece 2 and the temperature sensor 3. The clamping piece 1 is coated outside the heat conduction piece 2, can be formed by hot molding, and can also be formed by assembling components in a split manner. The clamping piece 1 is provided with a second through hole 11, and the second through hole 11 is used for penetrating the blood path tube 7. The second through hole 11 is coaxial with the first through hole 21, and the inner diameter of the second through hole 11 is not smaller than that of the first through hole 21; in the present embodiment, the inner diameter of the second through hole 11 is equal to the inner diameter of the first through hole 21. The clamping piece 1 is also provided with a third through hole 12, the third through hole 12 is coaxial with the blind hole 22 of the heat conduction piece 2, and the diameter of the third through hole 12 is not smaller than that of the blind hole 22; the diameter of the third through hole 12 is equal to the diameter of the blind hole 22 in this embodiment.
The heat conductor 2 is an aluminum-copper alloy member, and therefore has excellent heat conduction efficiency. The heat conductor 2 is provided with a first through hole 21, and the first through hole 21 is also used for passing the blood line tube 7, as is the case with the second through hole 11. One side of first through-hole 21 towards the axis is not wrapped by fastener 1 to guarantee that the pore wall of first through-hole 21 can closely laminate with blood way pipe 7, thereby can transmit the heat (heat comes from reinfusion liquid) of blood way pipe 7 to heat-conducting member 2, make heat-conducting member 2 equal or approximate with the temperature of blood way pipe 7. The heat conductor 2 is further provided with a blind hole 22, and the blind hole 22 is used for inserting or accommodating the detection end of the temperature sensor 3. Because the temperature sensor 3 is directly adopted to sense the temperature of the return liquid (generally attached to the blood path tube 7, the temperature of the blood path tube 7 is sensed), the contact area between the temperature sensor and the blood path tube 7 is too small, and the measured temperature deviation is larger; the blind hole 22 can completely surround the detection end of the temperature sensor 3, thereby improving the authenticity of the temperature sensor 3 in measuring the temperature. The heat conductor 2 has excellent heat conduction efficiency, and the temperatures of the heat conductor 2, the hole wall of the blind hole 22 and the blood path pipe 7 are almost the same in actual measurement, so that the temperature of the feedback liquid can be measured in an indirect measurement mode.
The detection end of the temperature sensor 3 is inserted into the blind hole 22 after passing through the third through hole 12. The temperature sensor 3 is connected with a temperature monitor 4 through a lead 5. The temperature sensor 3 senses the temperature of the hole wall of the blind hole 22 to form an electric signal, and the electric signal is transmitted to the temperature monitor 4 through the lead 5. The temperature monitor 4 converts the electrical signal from the temperature sensor 3 into a measured temperature, and then displays the measured temperature on its display screen 41 for the medical staff to view. Generally, the temperature sensor 3 and the temperature monitor 4 are powered by a direct current 12V power supply.
The detection end of the temperature sensor 3 is inserted into the blind hole 22 of the heat conduction piece 2, the hole wall of the blind hole 22 surrounds the detection end, and the temperature signal sensed by the temperature sensor 3 is closer to the temperature of the heat conduction piece 2; the heat conduction member 2 is closely attached to the blood path tube 7 (which is regarded as the same temperature as the return liquid), and the heat of the blood path tube 7 is transferred to the heat conduction member 2, so that the heat loss is little; thus, the temperature of the liquid in the blood path pipe 7 can be indirectly measured by the temperature sensor 3; the temperature sensor 3 sends the electric signal to the temperature monitor 4, the electric signal forms a measured temperature after the conversion of the temperature monitor 4, and the measured temperature is displayed on the temperature monitor 4, so that medical personnel can conveniently check the temperature of the reinfused liquid; the blood temperature monitor is additionally arranged on the hemodialysis machine 6, so that the hemodialysis machine 6 has the function of feeding back the temperature of the transfusion liquid in real time.
In the present embodiment, the first through hole 21 and the second through hole 11 are both C-shaped holes, and the side cutouts of the first through hole 21 and the second through hole 11 are in the same direction. Specifically, the first through hole 21 is provided with a first notch 23 on the side, and the length of the first notch 23 is equal to the depth of the first through hole 21; and a second gap 13 is arranged on the side part of the second through hole 11, and the length of the second gap 13 is equal to the depth of the second through hole 11. The blood way pipe 7 can be installed in the first through hole 21 and the second through hole 11 through the gaps after being pressed and deformed, and the blood way pipe 7 is convenient to install and detach. Generally, the width of the second gap 13 is smaller than the width of the second gap 13.
In this embodiment, the clamping piece 1 is further provided with a screw hole 14, an axis of the screw hole 14 is perpendicular to an axis out-of-plane of the second through hole 11, and the screw hole 14 and the second notch 13 are respectively located on two sides of the clamping piece 1. Through screw and screw hole 14, can fix fastener 1 on the wallboard of hemodialysis machine 6, conveniently use with hemodialysis machine 6 combination.
Example 2
