FIXING CLAMP FOR OPTICAL SENSING DETECTION IN Luso7159
TUBE
The utility model relates to the technical field of medical devices, in particular to a fixing clamp for optical sensing detection in a tube.
Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. This method involves diverting blood from the body to the outside, and in a dialyzer consisting of numerous hollow fibers, blood and an electrolyte solution (dialysate) with a similar concentration to that of the organism undergo material exchange through diffusion, ultrafiltration, adsorption, and convection inside the hollow fibers, thus removing metabolic waste from the body and maintaining electrolyte and acid-base balance.
Chinese Patent Application No. CN218793315U discloses a fixing clamp for a hemodialysis tube with a light-sensitive detection device. The fixing clamp comprises a clamping piece a and a clamping piece b matched with the clamping piece a, and the clamping piece a and the clamping piece b are connected via a rotating connector. The clamping piece a and the clamping piece b are each provided with an artery groove and a vein groove which are arc-shaped. The clamping piece a is provided with two LEDs which are arranged within the artery groove and the vein groove respectively. The clamping piece b is provided with two color receiving sensors for receiving light from the LEDs which are arranged within the artery groove and the vein groove respectively. The LEDs emit light directly onto the color receiving sensors. The clamping piece a is provided with a bed sheet clip, and the clamping piece b is provided with a control board. The control board is electrically connected with the two color receiving sensors. The color receiving sensors receive light signals from the LEDs after transmission through an infusion tube, and convert the light signals into voltage signals.
Following amplification and conversion by an A/D converter, the signals are transmitted to the control board which is provided with a detection module in 1
BL-5861 which a reference value is stored. LU507159
The aforementioned device conducts measurement by illuminating LED light and using the color receiving sensors for sensing. As a result, during measurement, external light can infiltrate the clamping piece through the tube, affecting the color receiving sensors and causing misjudgments. Additionally, the fixing clamp is only secured onto the tube, and because the tube is soft, the fixing clamp is unstable, potentially compromising the accuracy of the color receiving sensors.
The utility model aims to overcome the drawbacks in the prior art that external light can infiltrate a clamping piece through a tube, thus affecting color receiving sensors and causing misjudgments; and a fixing clamp is only secured onto the tube, and because the tube is soft, the fixing clamp is unstable, potentially compromising the accuracy of the color receiving sensors.
A fixing clamp for optical sensing detection in a tube is proposed, comprising a first fixing box, a second fixing box, magnetic attraction components for fixing positions of the first fixing box and the second fixing box, a detection device for detecting liquid in the tube, an alarm for reminding medical staff, clamping components for clamping the tube, an LED for illuminating the tube, a fixing clamp body for fixing a position, and locking components for locking the first fixing box and the second fixing box, wherein the first fixing box is hinged on the second fixing box by a hinge, and the magnetic attraction components are arranged at four corners of a bottom plate of the first fixing box; a cavity is formed at a center inside the first fixing box in a length direction of the first fixing box, the detection device is fixedly connected in a cavity of a first mounting box, the alarm is arranged in the first fixing box and fixedly connected to the bottom plate of the first fixing box, and the alarm is located at one side of the detection device and electrically connected with the detection device; the two clamping components are both connected to the first fixing box and located at two ends of the first mounting box respectively; a cavity is also formed in a second mounting box at a position corresponding to the first mounting box, and the LED is fixedly connected in the cavity of the second mounting box; the fixing clamp body is located at a center of the second fixing box and fixedly connected to a bottom plate of the second fixing 2
BL-5861 box in a length direction of the second fixing box; and the two locking components 507159 are symmetrically arranged above the second fixing box with the LED as a center, and the two locking components are both fixedly connected to the second fixing box.
In the technical scheme of the utility model, after the tube is placed in circular grooves at the centers of a first fixing box and a second fixing box, the first fixing box and the second fixing box will be fixed by locking components. At this point, a first clamping piece and a second clamping piece of a clamping component will securely clamp an outer wall of the tube through rubber pads, and gaps around the outer wall of the tube are sealed by the rubber pads, so that light is prevented from entering the first fixing box and the second fixing box from the gaps around the outer wall of the tube; and light refracted from the inside of the tube into the first fixing box and the second fixing box will be absorbed by black shading cloths, thereby avoiding the influence of external light on a detection device. This solution addresses the drawback in the prior art that external light entering the clamping pieces through the tube would affect color receiving sensors and lead to misjudgments.
After the tube is placed in the circular grooves at the centers of the first fixing box and the second fixing box, the tube is clamped by the clamping components at two ends of the first fixing box, so that the tube inside the first fixing box and the second fixing box is in a stretched state as the first fixing box and the second fixing box are fixed onto the tube in this way; and then the first fixing box and the second fixing box are fixed together by locking components. At this point, a guardrail of a hospital bed can be clamped by a fixing clamp body, or the first fixing box and the second fixing box are attracted onto one side of the hospital bed by magnetic attraction components. This approach effectively stabilizes the position of the tube using the first fixing box and the second fixing box, preventing any movement during use. This addresses the issue in the prior art that because the tube is soft, the fixing clamp is unstable, potentially compromising the accuracy of the color receiving sensors.
Preferably, the detection device is a color sensor, when an LED illuminates the tube, light from the LED will pass through the tube and be refracted on the 3
BL-5861 detection device. When detecting that the color of liquid inside the tube has | 507159 changed, a color sensor will transmit electrical signals to an alarm, and the alarm will sound to remind medical staff.
Preferably, the first fixing box and the second fixing box are provided with semicircular grooves in the length direction of the first fixing box and the second fixing box at centers, and shading cloths are arranged in the semicircular grooves of the first fixing box and the second fixing box respectively through adhering, the diameter of the groove is smaller than that of the tube, and corners of the groove are rounded. In this way, when the tube is put into the grooves of the first fixing box and the second fixing box, the corners of the groove will not pinch the tube, thus reducing the risk of tube rupture.
Preferably, the shading cloth is black, after light enters the first fixing box and the second fixing box through the refraction of the tube, the black shading cloths will start to absorb the light to reduce the brightness of the light, so as to avoid misjudgments of the detection device caused by excessive brightness.
Preferably, the locking component comprises an umbrella-shaped block and a stopper, the umbrella-shaped block is vertically and fixedly connected to the second fixing box, a groove is formed in the first fixing box at a position corresponding to the umbrella-shaped block, and the stopper is horizontally arranged in the groove of the first fixing box and fixedly connected to an inner wall of the groove of the first fixing box, after the tube 1s put into the first fixing box and the second fixing box, the first fixing box can be rotated to be closed. At this point, an umbrella-shaped block can be secured in the groove of the first fixing box through a stopper, so as to fix the relative positions of the first fixing box and the second fixing box and prevent sudden opening of the first fixing box and the second fixing box during use.
Preferably, the clamping component comprises a first clamping piece, a second clamping piece, a hinge shaft, a first spring and a second spring, and the hinge shaft is horizontally and fixedly connected to the first mounting box; both the first clamping piece and the second clamping piece are hinged on the hinge shaft; the first spring is sleeved on the hinge shaft and located inside the first clamping piece, one end of the first spring is connected with the hinge shaft, and the other 4
BL-5861 end of the first spring is connected with the first clamping piece; and the second | u507159 spring is sleeved on the hinge shaft and located in the second clamping piece, one end of the second spring is connected with the hinge shaft, and the other end of the second spring is connected with the second clamping piece, after the tube is put into the first fixing box and the second fixing box, the outer wall of the tube can be clamped by the first clamping piece and the second clamping piece, so that the tube is in a stretched state inside the first fixing box and the second fixing box, enabling efficient illumination by the LED and accurate detection by the detection device.
This minimizes the possibility of detector misjudgments resulting from the movement of the tube within the first fixing box and the second fixing box.
Preferably, rubber pads are arranged on inner walls of the first clamping piece and the second clamping piece, the surface roughness of the rubber pads is high, and the outer wall of the tube can be clamped through the friction force, so as to prevent the tube from sliding inside the clamping components at the two ends of the first fixing box due to an excessively smooth outer wall of the tube. Moreover, as the first clamping piece and the second clamping piece are held onto the outer wall of the tube through the rubber pads, when the clamping force of the first clamping piece and the second clamping piece is too large, the rubber pads can absorb the clamping force of the first clamping piece and the second clamping piece, preventing a reduction in the diameter of the tube and consequent blockage due to excessive clamping force.
Compared with the prior art, the utility model has the following beneficial effects: 1. The tube placed in the semicircular grooves of the first fixing box and the second fixing box is clamped and fixed by the clamping components at the two ends of the first fixing box, so that the tube in the first fixing box and the second fixing box is in a stretched state; and the light entering the first fixing box and the second fixing box from the tube is absorbed by the black shading cloths, so that a detection result of the detection device is more accurate and is not influenced by other waste liquid pipes prone to bending. 2. The first fixing box and the second fixing box which have been locked by the locking components and the tube wrapped in the first fixing box and the second 5
BL-5861 fixing box are fixed to the guardrail of the hospital bed through the fixing clamp | 5057159 body, or the first fixing box, the second fixing box and the tube are attracted onto the side of the hospital bed by the magnetic attraction components so as to fix the position of the tube, which prevents the decrease of the accuracy of the detection device due to the movement of the tube during detection.

The technical scheme in the embodiment of the utility model will be described in detail below with reference to Figs. 1-8 in the embodiment of the utility model.
As shown in Figs. 1-3, a fixing clamp 8 for optical sensing detection in a tube comprises a first fixing box 1 and a second fixing box 2, wherein the first fixing box 1 is hinged to the second fixing box 2 by a hinge, and magnetic attraction components 3 are arranged at four corners of the first fixing box 1; and after the tube is put into the first 6
BL-5861 fixing box 1 and the second fixing box 2 and clamped and fixed by clamping components 507159 6 at two ends of the first fixing box 1, the first fixing box 1, the second fixing box 2 and the tube are attracted onto one side of a hospital bed by the magnetic attraction components 3, so that the position of the tube is fixed. The clamping components 6 are vertically arranged at both ends of the first fixing box 1, and the two clamping components 6 are fixedly connected to the first fixing box 1 through hinge shafts 63 of the clamping components 6. When the first fixing box 1 rotates, the clamping components 6 will rotate together with the first fixing box 1.
As shown in Figs. 1-3, a fixing clamp body 8 is arranged on a bottom plate of the second fixing box 2, and the fixing clamp body 8 is fixedly connected to the bottom plate of the fixing box in a length direction of the second fixing box 2. After the tube is put into the first fixing box 1 and the second fixing box 2 and clamped and fixed by the clamping components 6 at the two ends of the first fixing box 1, besides using the magnetic attraction components 3 for fixation, a handrail of the hospital bed can also be clamped using the fixing clamp body 8. In this way, the position of the tube is fixed by the first fixing box 1 and the second fixing box 2. The first fixing box 1 and the second fixing box 2 are provided with semicircular grooves in the length direction of the first fixing box 1 and the second fixing box 2 at the centers, and corners of the semicircular grooves are rounded, so that when the first fixing box 1 and the second fixing box 2 clamp the tube, the semicircular grooves of the first fixing box 1 and the second fixing box 2 will not lead to tube rupture.
As shown in Figs. 1-3, the semicircular grooves of the first fixing box 1 and the second fixing box 2 are each provided with a shading cloth 11, and the shading cloth 11 is black. After light is refracted into the first fixing box 1 and the second fixing box 2 through the tube, the shading cloth 11 will absorb the light refracted into the first fixing box 1 and the second fixing box 2, so that the brightness of the light becomes low and the influence of the light on a detection device 4 is minimized. Slots are formed in the centers of the semicircular grooves of the first fixing box 1 and the second fixing box 2, a surface of the second fixing box 2 is provided with two locking components 9, and the two locking components 9 are symmetrically and vertically connected to the surface of the second fixing box 2 with the slot in the center of the semicircular groove of the second fixing box 2 as the center.
As shown in Figs. 1-3, a cavity is formed at the center inside the first fixing box 1 in the length direction of the first fixing box 1, and the detection device 4 is fixedly 7
BL-5861 connected inside a cavity of a first mounting box. The detection device 4 is a color sensor, | 597159 so the color of light displayed after an LED 7 illuminates the tube will be sensed by the detection device 4, and after sensing that the color of light changes, the detection device 4 will immediately transmit electrical signals to an alarm 5. The alarm 5 is arranged in the first fixing box 1 and located at one side of the detection device 4. The alarm 5 is fixedly connected to a bottom plate of the first fixing box 1 and electrically connected with the detection device 4. After receiving the electric signals given by the detection device 4, the alarm 5 will immediately sound to remind medical staff.
As shown in Figs. 4-7, a cavity 1s also formed in the second fixing box 2 at a position corresponding to the central cavity of the first fixing box 1. The LED 7 is fixedly connected inside the cavity of the second fixing box 2, and the LED 7 is perpendicular to the detection device 4. Therefore, when the LED 7 illuminates the tube, the light will be refracted through the tube onto the detection device 4 and detected by the detection device 4, and then the corresponding electric signals will be transmitted to the alarm 5. The locking component 9 comprises an umbrella-shaped block 91 and a stopper 92, wherein the umbrella-shaped block 91 is vertically and fixedly connected above the second fixing box 2; a groove is formed in a position corresponding to the umbrella-shaped block 91 on the first fixing box 1, and the stopper 92 is horizontally arranged in the groove and fixedly connected to an inner wall of the groove; after the tube is placed in the semicircular groove of the second fixing box 2, the first fixing box 1 can be rotated in an anticlockwise direction to be closed; and after the umbrella-shaped block 91 is placed in the groove in the first fixing box 1, the stopper 92 can be used to secure the umbrella-shaped block 91 inside the groove of the first fixing box 1, preventing sudden opening of the first fixing box 1 and the second fixing box 2 during use.
As shown in Fig. 8, the clamping component 6 comprises a first clamping piece 61, a second clamping piece 62, a hinge shaft 63, a first spring 64 and a second spring 65, wherein the hinge shaft 63 is horizontally and fixedly connected to the first mounting box; both the first clamping piece 61 and the second clamping piece 62 are hinged on the hinge shaft 63; the first spring 64 is sleeved on the hinge shaft 63 and located inside the first clamping piece 61, one end of the first spring 64 is connected with the hinge shaft 63, and the other end of the first spring 64 is connected with the first clamping piece 61; the second spring 65 is sleeved on the hinge shaft 63 and located in the second clamping piece 62, one end of the second spring 65 is connected with the hinge shaft 63, and the other end of the second spring 65 is connected with the second clamping piece 62; and both the first 8
BL-5861 spring 64 and the second spring 65 are torsion springs. When clamping the tube, the first | 5974159 clamping piece 61 and the second clamping piece 62 can rotate upwards around the hinge shaft 63. Because one end of the first spring 64 is connected with the hinge shaft 63 and the other end of the first spring 64 is connected with the first clamping piece 61.
As shown in Fig. 8, when the first clamping piece 61 rotates upwards around the hinge shaft 63, one end of the torsion spring will rotate together with the first clamping piece 61; because the other end of the first spring 64 is connected with the hinge shaft 63, when the first clamping piece 61 rotates, the first spring 64 will synchronously rotate to store energy; and then after the tube is put into the first clamping piece 61 and the second clamping piece 62, the first clamping piece 61 can be released, and the energy stored in the first spring 64 during the upward rotation of the first clamping piece 61 is utilized to drive the first clamping piece 61 downward for reset rotation until an inner wall of the first clamping piece 61 contacts an outer wall of the tube. Similarly, when the second clamping piece 62 is rotated upwards, the second spring 65 will also store energy synchronously.
After releasing the second spring 65, the second spring 65 will drive the second clamping piece 62 for reset rotation.
As shown in Fig. 8, rubber pads 66 are arranged on inner walls of the first clamping piece 61 and the second clamping piece 62, and the surface roughness of the rubber pads 66 is high. When the first clamping piece 61 and the second clamping piece 62 clamp the tube, an outer wall of the tube can be clamped through the friction force on surfaces of the rubber pads 66, so as to prevent the tube from sliding inside the clamping components 6 at the two ends of the first fixing box 1 due to an excessively smooth outer wall of the tube.
Moreover, as the first clamping piece 61 and the second clamping piece 62 are held onto the outer wall of the tube through the rubber pads 66, when the clamping force of the first clamping piece 61 and the second clamping piece 62 is too large, the rubber pads 66 can absorb the clamping force of the first clamping piece 61 and the second clamping piece 62, preventing a reduction in the diameter of the tube and consequent blockage due to excessive clamping force.
The movement process of this embodiment is as follows. After the first fixing box 1 is rotated in a clockwise direction around the hinge to be opened, the tube can be put into the semicircular groove in the center of the second fixing box 2, and then the first fixing box 1 can be rotated in an anticlockwise direction; after the umbrella-shaped block 91 of the locking component 9 is put into the groove of the first fixing box 1 and secured by the stopper 92, the clamping components 6 at the two ends of the first fixing box 1 can be 9
BL-5861 used to clamp the outer wall of the tube, and then the LED 7 and the detection device 4 are | 507459 started; at the same time, after it is determined that the detection device 4 can correctly detect the color of the light emitted by the LED 7 and refracted by the tube and can transmit the electric signals to the alarm 5, the first fixing box 1 and the second fixing box 2 can be clamped onto a guardrail of the hospital bed through the fixing clamp body 8 as needed, or the first fixing box 1 and the second fixing box 2 can be attracted onto one side of the hospital bed through the magnetic attraction components 3.
The above embodiments only illustrate the technical idea of the utility model, and cannot be used to limit the protection scope of the utility model. Any changes made on the basis of the technical scheme according to the technical idea proposed by the utility model fall within the protection scope of the utility model. 10
