Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a liquid container residual amount detection and fixing device. Background Art

[0002] For some liquids with light-shielding properties, they are usually stored in opaque containers or transparent containers with opaque covers. For example, during gastrointestinal endoscopic surgery, mucosal dyes of different components are often needed. Since the dyes have the property of light-shielding, they need to be stored in glass containers with opaque silicone covers. In order to avoid running out of dyes during mucosal dyeing, a dye residue detection device is often used to measure the dye residue.

[0003] For example, a Chinese patent discloses a dye container remaining amount detection device [authorization announcement number is CN213956506U], which includes a first detection component, a second detection component and a control module. The first detection component transmits a detection signal to the dye container, and the second detection component receives the signal fed back by the dye container and transmits it to the control module.

[0004] The first detection component and the second detection component are laser sensors. The detection method using laser sensors requires very high accuracy in the assembly of the dye container. If the dye container is assembled skewed, inaccurate detection or failure to detect may occur easily. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the prior art and to provide a liquid container residual amount detection and fixing device which has good liquid container fixing effect.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A liquid container remaining amount detection and fixing device comprises a device body, wherein the device body is provided with a positioning plane for placing the liquid container, the positioning plane is provided with a positioning protrusion whose cross-sectional shape is adapted to the cross-sectional shape of the inner cavity of the liquid container, and the liquid container positioned on the positioning protrusion extends in the vertical direction.

[0008] There are many types of liquid containers. Here, a dye container is used for illustration. The dye container includes a container body and a rodless piston assembly. The front end of the container body is provided with a feeding port. The rodless piston assembly is sealed and slidably connected with the inner wall of the container body. When positioning, the dye container is placed on the positioning protrusion with the feeding port facing upward, and the positioning protrusion penetrates into the dye container to achieve the purpose of vertically positioning the dye container.

[0009] A laser sensor is arranged on the positioning protrusion to judge the remaining amount of dye in the liquid container by detecting the position of the piston. Alternatively, a liquid level sensor (a liquid level sensor of model XKC-Y23A) is arranged on the side of the liquid container on the device body. The liquid level sensor can detect the remaining amount of the internal liquid (dye) through the opaque liquid container or through the transparent container covered with an opaque cover.

[0010] In the above-mentioned liquid container remaining amount detection and fixing device, a first clamping arm and a second clamping arm are arranged opposite to each other on the device body, and the first clamping arm has a first clamping concave surface adapted to the outer surface of the liquid container on the side facing the second clamping arm, and the second clamping arm has a second clamping concave surface adapted to the outer surface of the liquid container on the side facing the first clamping arm, and the center line of the liquid container clamped between the first clamping arm and the second clamping arm is located between the first clamping concave surface and the second clamping concave surface.

[0011] The first clamp arm and the second clamp arm have a certain elasticity, and a clamping space adapted to the liquid container is formed therebetween. The clamping space has an opening for the liquid container to enter, and the width of the opening is smaller than the outer diameter of the liquid container. The first clamp arm, the second clamp arm and the positioning protrusion jointly position the liquid container, thereby improving stability.

[0012] In order to ensure that the liquid level sensor is completely fitted to the liquid container during detection, the liquid level sensor can be set between the first clamp arm and the second clamp arm. When the first clamp arm and the second clamp arm clamp the liquid container in place, the liquid level sensor is just attached to the outer wall of the dye solvent.

[0013] In the above-mentioned liquid container remaining amount detection and fixing device, the side of the device body is provided with a storage bin for placing the liquid container and having an open opening, the positioning plane is the lower side of the storage bin, the first clamp arm and the second clamp arm are arranged in the storage bin, and the opening of the storage bin is provided with a door panel for covering the storage bin.

[0014] The door panels provided can protect components such as liquid containers and sensors.

[0015] In the above-mentioned liquid container remaining amount detection and fixing device, the side of the storage bin where the first clamp arm and the second clamp arm are arranged is arranged opposite to the door panel in the closed state. When the door is closed, the door panel can push the liquid container to the correct position between the first clamp arm and the second clamp arm.

[0016] This arrangement can better fit the liquid level sensor to the outer wall of the dye solvent.

[0017] In the above-mentioned liquid container remaining amount detection and fixing device, a tube clamp is provided on the door panel, and the tube clamp has a pressing concave surface adapted to the outer surface of the liquid container, and when the door panel is in a closed state, the pressing concave surface presses on the liquid container.

[0018] The first clamping concave surface, the second clamping concave surface and the pressing concave surface work together to clamp the liquid container until it is correctly clamped, and at this time, the positioning protrusion is coaxial with the liquid container.

[0019] In the above-mentioned liquid container remaining amount detection and fixing device, the contact point between the pressing concave surface and the liquid container is lower than the contact point between the first clamping concave surface and the liquid container.

[0020] In the above-mentioned liquid container remaining amount detection and fixing device, the door panel is rotatably arranged at the opening of the storage compartment.

[0021] The residual amount of dye in multiple liquid containers can be detected simultaneously in the storage bin. Each liquid container has a corresponding positioning protrusion, a first clamping arm, a second clamping arm and a pipe clamp, so as to realize synchronous monitoring of the residual amount of dye in different liquid containers.

[0022] Compared with the prior art, the liquid container residual detection and fixing device has the following advantages: the positioning protrusion, the first clamp arm, the second clamp arm and the pipe clamp can effectively ensure that the liquid container is assembled in place, avoiding the risk of being unable to detect the residual dye; it is easy to install, has a good fixing effect on the liquid container, is not easy to loosen after being fixed, and has a long service life.

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] The liquid container residual amount detection and fixing device is used to position the liquid container 2. In this embodiment, it is used to position the dye container. The dye container includes a cylindrical container body and a rodless piston assembly. The front end of the container body is provided with a feeding port, and the rear end is open. The rodless piston assembly is sealed and slidably connected with the inner wall of the container body. When positioning, the dye container 2 is placed on the positioning protrusion 4 with the feeding port facing upward. The positioning protrusion 4 penetrates into the dye container from the open end of the dye container, so as to achieve the purpose of vertically positioning the dye container.

[0029] like Figure 1 The liquid container remaining amount detection and fixing device shown includes a device body 1, and one side of the device body 1 is provided with a storage bin 7 with an opening for placing the liquid container 2, the lower side of the storage bin 7 is a positioning plane 3, and a door panel 8 for covering the storage bin 7 is rotatably installed at the opening of the storage bin 7, and the storage bin 7 can be completely enclosed when the door panel 8 is closed.

[0030] like Figure 2 As shown, a positioning protrusion 4 having a cross-sectional shape that matches the cross-sectional shape of the inner cavity of the liquid container 2 is provided on the positioning plane 3. Since the cross-sectional shape of the inner cavity of the liquid container 2 is circular, the cross-sectional shape of the positioning protrusion 4 is also circular, and the liquid container 2 positioned on the positioning protrusion 4 extends upward in the vertical direction.

[0031] A laser sensor is arranged on the positioning protrusion 4 to determine the remaining amount of dye in the liquid container 2 by detecting the position of the piston.

[0032] In some other embodiments, a liquid level sensor (such as a liquid level sensor with model number XKC-Y23A) is provided on the device body 1 and is located on the side of the liquid container 2. The liquid level sensor can detect the internal liquid residue through the opaque liquid container 2 or through a transparent container covered with an opaque cover.

[0033] In order to fix the upper part of the liquid container 2, as shown in FIG. Figure 1 and Figure 3 As shown, a first clamping arm 5 and a second clamping arm 6 are arranged opposite to each other on the device body 1, and the first clamping arm 5 has a first clamping concave surface matched with the outer surface of the liquid container 2 on the side facing the second clamping arm 6, and the second clamping arm 6 has a second clamping concave surface matched with the outer surface of the liquid container 2 on the side facing the first clamping arm 5, and the midline of the liquid container 2 clamped between the first clamping arm 5 and the second clamping arm 6 is located between the first clamping concave surface and the second clamping concave surface.

[0034] The first clamp arm 5 and the second clamp arm 6 have a certain elasticity, and a clamping space adapted to the liquid container 2 is formed therebetween. The clamping space has an opening for the liquid container 2 to enter, and the width of the opening is smaller than the outer diameter of the liquid container 2. The first clamp arm 5, the second clamp arm 6 and the positioning protrusion 4 jointly position the liquid container 2, thereby improving stability.

[0035] In order to ensure that the liquid level sensor is completely in contact with the liquid container 2 during detection, the liquid level sensor can be set between the first clamp arm 5 and the second clamp arm 6. When the first clamp arm 5 and the second clamp arm 6 clamp the liquid container 2 in place, the liquid level sensor is just in contact with the outer wall of the dye solvent.

[0036] like Figure 1 and Figure 3 As shown, the side of the storage bin 7 where the first clamp arm 5 and the second clamp arm 6 are arranged is opposite to the door panel 8 in the closed state. When the door is closed, the door panel 8 can push the liquid container 2 to the correct position between the first clamp arm 5 and the second clamp arm 6, so that the liquid level sensor can better fit the outer wall of the dye solvent.

[0037] like Figure 1 and Figure 3 As shown, the door panel 8 is provided with a pipe clamp 9, which has a pressing concave surface adapted to the outer surface of the liquid container 2. When the door panel 8 is in a closed state, the pressing concave surface presses on the liquid container 2. The first clamping concave surface, the second clamping concave surface and the pressing concave surface work together to clamp the liquid container 2 until it is properly clamped. At this time, the positioning protrusion 4 is coaxial with the liquid container 2.

[0038] In this embodiment, the contact point between the pressing concave surface and the liquid container 2 is lower than the contact point between the first clamping concave surface and the liquid container 2 .

[0039] like Figure 1 As shown, the residual amount of dye in multiple (such as 3) liquid containers 2 can be detected simultaneously in the storage bin 7. Each liquid container 2 has a corresponding positioning protrusion 4, a first clamping arm 5, a second clamping arm 6 and a pipe clamp 9, so as to realize synchronous monitoring of the residual amount of dye in different liquid containers 2.

[0040] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
