Description

Technical Field

[0001] This utility model relates to the field of hemodialysis equipment technology, specifically to a dual-channel liquid level detection clamp for a hemodialysis machine. Background Technology

[0002] Hemodialysis machines are primarily used to replace kidney function, helping patients remove waste products and excess water from their blood. Their working principle is based on a semi-permeable membrane, using physical processes such as diffusion, convection, and adsorption to exchange substances between the patient's blood and the dialysate.

[0003] In the external circulation tubing of existing hemodialysis equipment, there is usually an arterial drip chamber and a venous drip chamber. However, the hemodialysis equipment only has one drip chamber level detection channel, which cannot detect the level of all drip chambers, resulting in incomplete detection. Utility Model Content

[0004] The purpose of this invention is to provide a dual-channel liquid level detection clip for hemodialysis machines, which can simultaneously monitor the liquid level and liquid temperature in both intravenous and arterial drip chambers, providing more comprehensive monitoring.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A dual-channel liquid level detection clip for a hemodialysis machine includes a mounting component for installation on the outer surface of the hemodialysis machine. The mounting component has a through-hole for placing an arterial drip chamber and a through-hole for placing a venous drip chamber. Both the arterial and venous drip chambers are equipped with monitoring probes for detecting the liquid level in the drip chambers. Its function is to allow for the simultaneous placement of both arterial and venous drip chambers and the monitoring probes, enabling comprehensive monitoring of the liquid levels in both chambers.

[0007] Furthermore, the mounting component includes a base and a cover hinged to the base. The cover has observation windows for directly observing the arterial drip chamber in the arterial drip chamber placement slot and the venous drip chamber in the venous drip chamber placement slot. Both the arterial drip chamber placement slot and the venous drip chamber placement slot are composed of the cover and the base. The purpose of these observation windows is to allow direct access to the liquid levels of the arterial and venous drip chambers within the base, preventing the inability to observe liquid level changes when the monitoring probe fails.

[0008] Furthermore, both the arterial drip chamber and the venous drip chamber are equipped with temperature sensors for monitoring the temperature of the liquid inside the drip chamber. Their function is to detect the temperature of the arterial and venous drip chambers through the placement of the temperature sensors.

[0009] Furthermore, the monitoring probe includes corresponding transmitting and receiving ends. The arterial drip chamber placement slot and the venous drip chamber placement slot each have a receiving end and a transmitting end on opposite sides. A temperature sensor is located on the side of the arterial or venous drip chamber placement slot opposite to the cap. The monitoring probe uses an infrared sensor or an ultrasonic sensor. Both the arterial and venous drip chamber placement slots are cylindrical with a concave cross-section. The arterial drip chamber placement slot has a receiving end and a transmitting end on opposite sidewalls, and a temperature sensor is located on the surface connecting the opposite sidewalls. Similarly, the venous drip chamber placement slot has a receiving end and a transmitting end on opposite sidewalls, and a temperature sensor is located on the surface connecting the opposite sidewalls.

[0010] Furthermore, the receiving end is at the same height as the transmitting end, and the height of the receiving end is greater than the height of the temperature sensor. This is because, since the liquid in the arterial or venous drip chamber is below the liquid surface, placing the temperature sensor below the monitoring probe allows for effective measurement of the liquid temperature in the arterial or venous drip chamber.

[0011] Furthermore, a rear end cover is detachably connected to the rear end of the base. The base has embedding slots for embedding the receiver or transmitter. The embedding slots for embedding the receiver in the arterial drip chamber placement slot or the venous drip chamber placement slot are connected to the embedding slots for embedding the transmitter. The rear end cover has a probe clamping plate for simultaneously closing all embedding slots. The probe clamping plate is cuboid in shape. Its function is to fix all monitoring probes in place.

[0012] Furthermore, the rear end cover is provided with a wire hole corresponding to the embedding groove for the wires connected to the monitoring probe to pass through.

[0013] Furthermore, the cap is equipped with a pressure block for pressing the arterial drip pot onto the temperature sensor in the arterial drip pot placement slot or the venous drip pot onto the temperature sensor in the venous drip pot placement slot. Its function is to ensure that the arterial or venous drip pot is in close contact with the temperature sensor, thereby ensuring the accuracy of temperature measurement.

[0014] Furthermore, both the arterial drip chamber placement slot and the venous drip chamber placement slot are provided with support plates on their bottom surfaces for supporting the arterial or venous drip chamber, and the support plates are provided with cable passage openings. The purpose of these cable passage openings is to allow the infusion tubing, which is dynamically connected to the bottom of the arterial or venous drip chamber, to pass through.

[0015] Furthermore, the top of the cap is provided with a limiting plate to prevent the arterial drip or venous drip from moving upward.

[0016] The beneficial effects of this utility model are:

[0017] 1. Its function is to simultaneously place arterial drip chambers and venous drip chambers, as well as monitor the liquid levels in the arterial and venous drip chambers, through the setting of arterial drip chamber placement slots, venous drip chamber placement slots, and monitoring probes, providing comprehensive monitoring.

[0018] 2. The observation window allows direct access to the liquid levels of the arterial and venous drip chambers within the base, preventing the inability to observe level changes when the monitoring probe fails. Attached Figure Description

[0025] Example 1

[0026] A dual-channel liquid level detection clip for hemodialysis machines, such as Figure 1 As shown, the device includes a mounting component 1 for installation on the outer surface of a hemodialysis machine. The mounting component 1 has a through-hole for an arterial drip chamber (2) and a through-hole for a venous drip chamber (3). Both the arterial drip chamber 2 and the venous drip chamber 3 are equipped with monitoring probes 4 for detecting the drip level. The function of these two locations, along with the monitoring probes 4, is to simultaneously place both arterial and venous drip chambers and monitor their respective drip levels, providing comprehensive monitoring.

[0027] Specifically, such as Figure 1 As shown, the mounting component 1 includes a base and a cover 5 hinged to the base. The cover 5 has an observation window 6 for directly observing the arterial drip chamber in the arterial drip chamber placement slot 2 and the venous drip chamber in the venous drip chamber placement slot 3. Both the arterial drip chamber placement slot 2 and the venous drip chamber placement slot 3 are composed of the cover 5 and the base. Its function is that, through the observation window 6, the liquid level of the arterial and venous drip chambers within the base can be directly observed, preventing the inability to observe liquid level changes when the monitoring probe 4 fails.

[0028] Specifically, such as Figure 1 As shown, both the arterial drip chamber placement slot 2 and the venous drip chamber placement slot 3 are equipped with temperature sensors 7 for monitoring the temperature of the liquid inside the drip chamber. Their function is to detect the temperature of the arterial and venous drip chambers through the placement of the temperature sensors 7.

[0029] Specifically, such as Figure 1 As shown, the monitoring probe 4 includes corresponding transmitting ends 8 and receiving ends 9. Receiving ends 9 and transmitting ends 8 are respectively provided on opposite sides of the arterial drip chamber placement slot 2 and the venous drip chamber placement slot 3. A temperature sensor 7 is located on the side of the arterial drip chamber placement slot 2 or the venous drip chamber placement slot 3 opposite to the cover 5. The monitoring probe 4 uses an infrared sensor or an ultrasonic sensor. Both the arterial drip chamber placement slot 2 and the venous drip chamber placement slot 3 are cylindrical with a concave cross-section. Receiving ends 9 and transmitting ends 8 are respectively provided on the two opposite side walls of the arterial drip chamber placement slot 2, and the temperature sensor 7 is located on the surface connecting the two opposite side walls of the arterial drip chamber placement slot 2; similarly, receiving ends 9 and transmitting ends 8 are respectively provided on the two opposite side walls of the venous drip chamber placement slot 3, and the temperature sensor 7 is located on the surface connecting the two opposite side walls of the venous drip chamber placement slot 3.

[0030] Specifically, such as Figure 1As shown, the receiver 9 is at the same height as the transmitter 8, and the height of the receiver 9 is greater than the height of the temperature sensor 7. Its function is that, since the liquid in the arterial or venous drip chamber is below the liquid surface, placing the temperature sensor 7 below the monitoring probe 4 allows for effective measurement of the liquid temperature in the arterial or venous drip chamber.

[0031] Specifically, such as Figure 2 As shown, a rear end cover 10 is detachably connected to the rear end of the base. The base has embedding slots 11 for embedding the receiver 9 or transmitter 8. The embedding slots 11 for embedding the receiver 9 in the arterial drip chamber placement slot 2 or the venous drip chamber placement slot 3 are connected to the embedding slots 11 for embedding the transmitter 8. The rear end cover 10 has a probe pressure plate 12 for simultaneously closing all embedding slots 11. The probe pressure plate 12 is cuboid in shape. Its function is to fix all monitoring probes 4 in place.

[0032] Specifically, such as Figure 2 As shown, the rear cover 10 is provided with a wire hole 13 corresponding to the embedding groove 11 for the wires connected to the monitoring probe 4 to pass through.

[0033] Specifically, such as Figure 1 As shown, the cover 5 is provided with a pressure block 14 for pressing the arterial drip pot onto the temperature sensor 7 in the arterial drip pot placement slot 2 or the venous drip pot onto the temperature sensor 7 in the venous drip pot placement slot 3. Its function is to ensure that the arterial or venous drip pot is in close contact with the temperature sensor 7, thereby ensuring the accuracy of temperature measurement.

[0034] Specifically, such as Figure 1 As shown, both the arterial drip chamber placement slot 2 and the venous drip chamber placement slot 3 have support plates 15 on their bottom surfaces for supporting the arterial or venous drip chamber. The support plates 15 have cable passage openings 16. The cable passage openings 16 allow the infusion tube, which is connected to the bottom of the arterial or venous drip chamber, to pass through.

[0035] Specifically, such as Figure 1 As shown, the top of the cover 5 is provided with a limiting plate 17 for preventing the arterial drip or venous drip from moving upward.

[0036] The working principle of this embodiment is explained as follows: The arterial drip chamber and the venous drip chamber are placed in the arterial drip chamber placement slot 2 and the venous drip chamber placement slot 3, respectively. The support plate 15 supports the arterial drip chamber and the venous drip chamber, and the infusion tubes connected to the bottom of the arterial drip chamber and the venous drip chamber pass through their respective inlet 16. The arterial drip chamber is installed in the arterial drip chamber placement slot 2, and the venous drip chamber is installed in the venous drip chamber placement slot 3. When the liquid level in both the arterial drip chamber and the venous drip chamber is higher than the monitoring probe 4, the signal emitted by the transmitter 8 is blocked by the liquid in the drip chamber, so that the receiver 9 cannot receive the signal. At this time, it means that the drip chamber is working normally. When the receiver 9 receives the signal emitted by the transmitter 8, it means that the liquid level in the drip chamber is lower than the monitoring probe 4. The receiver 9 sends the signal to the corresponding alarm system using existing technology to remind the operator to check in time.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
