In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0040] In the field of organ transplantation, in order to ensure the normal blood supply of the organ, the donor needs to be supplemented with blood from outside. In the related art, blood is stored in a disposable blood reservoir. In order to clearly know the blood volume inside the blood reservoir, a liquid level sensor is often set on the blood reservoir.

[0041] Existing liquid level sensors are often fixed to the blood reservoir by bolts or glue. Since the blood reservoir is a disposable item, the liquid level sensor needs to be removed from the blood reservoir after use. The removal process is troublesome, time-consuming and labor-intensive.

[0042] In order to solve the above problems, the first embodiment of the present application proposes a liquid level sensor installation structure, which includes a liquid level sensor 100 and a plug-in body 200, wherein the plug-in body 200 is used to connect with a liquid reservoir 300, and the liquid reservoir 300 can be used to store blood, liquid medicine, etc., depending on the specific application scenario. The plug-in body 200 defines a card slot, and the card slot has a first opening 240 for inserting the liquid level sensor 100. In the example Figures 1 to 5 In the illustrated embodiment, the first opening 240 of the card slot is disposed upward. In other embodiments, the first opening 240 of the card slot may also be disposed to the left, to the right, or tilted, and may be changed according to application scenarios.

[0043] The plug body 200 is an annular structure. Both ends of the plug body 200 are open along the thickness direction. Therefore, when the liquid level sensor 100 is inserted into the plug body 200 , the liquid level sensor 100 can abut against the liquid reservoir 300 .

[0044] In such Figure 1 , Figure 2 and Figure 6In the embodiment shown, the plug-in body 200 is disposed on the outer peripheral surface of the liquid reservoir 300, and the liquid level sensor 100 includes an abutment member 110. When the liquid level sensor 100 is inserted into the plug-in body 200, the displacement of the liquid level sensor 100 is limited by the plug-in body 200, and the abutment member 110 of the liquid level sensor 100 abuts against the liquid reservoir 300. Thus, the liquid level sensor 100 detects the liquid capacity in the liquid reservoir 300 across the shell structure of the liquid reservoir 300. For example, the liquid level sensor 100 may be a capacitive type, and obtains its liquid storage amount information by detecting the capacitance change of the liquid reservoir 300. Alternatively, the liquid level sensor 100 may also be an ultrasonic type, and obtains its liquid level height information by the ultrasonic reflection principle. Alternatively, the liquid level sensor 100 may also be a radar type, etc.

[0045] In other embodiments, the plug-in body 200 may also be disposed in the wall of the liquid storage cavity of the liquid reservoir 300, so that the liquid capacity in the liquid storage cavity can be detected by providing a contact liquid level sensor 100, such as a static pressure liquid level sensor 100.

[0046] The plug-in body 200 and the liquid reservoir 300 can be connected in a detachable manner such as bonding, adhesive bonding, or clamping, or the plug-in body 200 can be integrally injection molded with the liquid reservoir 300. It is understandable that when it is necessary to detect the liquid content in a certain liquid reservoir 300, the liquid level sensor 100 is inserted into the plug-in body 200 on the liquid reservoir 300; when it is no longer necessary to detect the liquid content in the liquid reservoir 300, the liquid level sensor 100 is removed from the plug-in body 200, and the disassembly and assembly process is relatively simple, so that the liquid level sensor 100 can be reused.

[0047] Furthermore, since the manufacturing cost of the plug body 200 is low, the disposal cost of the plug body 200 is low. When the liquid reservoir 300 is a disposable device, after the liquid reservoir 300 is used, it is not necessary to remove the plug body 200 from the liquid reservoir 300, and the liquid reservoir 300 and the plug body 200 are discarded together, thereby avoiding time-consuming and labor-intensive disassembly steps.

[0048] In some embodiments, in order to make the plugging of the liquid level sensor 100 and the plugging body 200 tighter, the abutment member 110 is further provided with a soft portion 113, such as Figures 4 to 6 As shown, the soft part 113 is made of a sheet-like soft material, which can be elastically deformed under pressure and can be made of rubber, silicone, etc. When the liquid level sensor 100 is plugged into the plug body 200 , the soft part 113 is arranged in contact with the outer peripheral surface of the liquid reservoir 300 .

[0049] In such Figure 6In the embodiment shown, the outer peripheral surface of the liquid reservoir 300 is arc-shaped, so that the liquid level sensor 100 and the liquid reservoir 300 can be more closely fitted through the elastic deformation of the soft portion 113, avoiding the gap between the liquid level sensor 100 and the liquid reservoir 300 after plugging, which affects the measurement accuracy of the liquid level sensor 100. In other embodiments, the outer peripheral surface of the liquid reservoir 300 can also be a plane, so as to facilitate the connection between the plug-in body 200 and the liquid reservoir 300, and the connection between the liquid level sensor 100 and the liquid reservoir 300.

[0050] In some embodiments, the abutment member 110 includes a base 111, and the soft portion 113 is mounted on the base 111. For the convenience of subsequent description, the plane connecting the base 111 and the soft portion 113 is defined as a mounting surface, and the mounting surface is provided with a plurality of mounting holes 1111, such as Figure 5 and Figure 6 As shown, a plurality of mounting holes 1111 are evenly distributed on the mounting surface. A plurality of mounting protrusions 1131 are arranged on the side of the soft part 113 close to the base 111, and the mounting protrusions 1131 are inserted into the mounting holes 1111, so that the hole wall of the mounting hole 1111 is covered by the mounting protrusions 1131, so that the soft part 113 is connected to the base 111. The soft part 113 can be formed on the base 111 by secondary injection molding, or the soft part 113 can be manufactured and formed separately, and then attached to the base 111 by gluing, bonding, etc. The mounting protrusions 1131 on the soft part 113 increase the contact area between the soft part 113 and the base 111, improve the covering effect of the soft part 113 and the base 111, make the connection between the soft part 113 and the base 111 tighter, and have higher bonding strength, so that it is not easy to separate.

[0051] It should be noted that when the liquid level sensor 100 is inserted into the plug-in body 200, in order to avoid large friction between the soft rubber part and the liquid reservoir 300, which may cause the liquid level sensor 100 and the plug-in body 200 to get stuck during plugging, lubricants such as varnish can be sprayed on the surface of the soft rubber before installation to facilitate the insertion of the liquid level sensor 100 into the plug-in body 200 and reduce the friction resistance during the plug-in process.

[0052] In some embodiments, the liquid level sensor 100 further includes a housing 120, such as Figures 4 to 6 As shown, the housing 120 is connected to the abutment 110, so that the housing 120 and the abutment 110 together define a closed accommodating cavity to accommodate the electronic control component 130 for detecting the liquid capacity. The housing 120 has a first surface 12111 and a second surface 12121 that are arranged opposite to each other, and the first surface 12111 and the second surface 12121 are respectively used to abut against the plug body 200. The first surface 12111 and the second surface 12121 are arranged obliquely relative to the abutment 110, and, as shown in FIG. Figure 6As shown in FIG. 1 , the distance between the first surface 12111 and the second surface 12121 gradually decreases in the direction away from the abutment member 110. Figures 1 to 3 In the frustum structure shown, when the liquid level sensor 100 is inserted into the plug-in body 200, the two sides of the plug-in body 200 respectively abut against the first surface 12111 and the second surface 12121, so that the liquid level sensor 100 can be subjected to a downward pressing force, so that the liquid level sensor 100 can fit more firmly on the outer peripheral surface of the liquid reservoir 300.

[0053] Furthermore, along the insertion direction of the liquid level sensor 100, the plug-in body 200 includes a first limit portion 210 and a second limit portion 220 respectively located on both sides of the plug-in direction. Figure 6 As shown, the distance between the first limiting portion 210 and the second limiting portion 220 gradually decreases in the direction away from the liquid reservoir 300. When the liquid level sensor 100 is inserted into the plug body 200, the first limiting portion 210 abuts against the first surface 12111, and the second limiting portion 220 abuts against the second surface 12121, so that the displacement of the liquid level sensor 100 is limited by the plug body 200.

[0054] Furthermore, along the insertion direction of the liquid level sensor 100, the plug body 200 further includes a first positioning portion 230 located in the insertion direction, and the first positioning portion 230 is used to define the limit position when the liquid level sensor 100 is inserted into the plug body 200. Figures 3 to 6 In the illustrated embodiment, since the first positioning portion 230 is located at the bottom of the plug-in body 200 , the first positioning portion 230 also serves to receive the liquid level sensor 100 , and can support and limit the liquid level sensor 100 .

[0055] Furthermore, if Figure 4 and Figure 5 As shown, a communication cable 131 is connected to the bottom of the liquid level sensor 100, one end of the communication cable 131 is connected to the electric control component 130 inside the liquid level sensor 100, and the other end is connected to an external electrical device such as a display or a controller, for transmitting the liquid level data detected by the liquid level sensor 100 to the display or the controller. In order to avoid the communication cable 131, an avoidance groove 231 is provided on the first positioning portion 230, so that when the liquid level sensor 100 is inserted into the plug body 200, the communication cable 131 is inserted into the avoidance groove 231.

[0056] In some embodiments, Figure 5As shown, the housing 120 includes a peripheral wall 121 and a top wall 122, and the peripheral wall 121 is connected to the edge of the top wall 122, so that the peripheral wall 121 and the top wall 122 define a receiving cavity with a first opening, wherein a first notch 1214 is further provided on the peripheral wall 121, and the first notch 1214 is communicated with the receiving cavity, and the abutment member 110 includes a base 111 and a flange 112, and one side of the base 111 is connected to the soft rubber, and the other side is connected to the flange 112. When the abutment member 110 is connected to the housing 120, the base 111 closes the first opening, and the flange 112 closes the first notch 1214.

[0057] Furthermore, the peripheral wall 121 includes a first edge wing 1211 and a second edge wing 1212 located on both sides of the first notch 1214, so as to Figure 5 Taking the embodiment shown as an example, the first notch 1214 is located at the bottom of the housing 120, the lower ends of the first edge wing 1211 and the second edge wing 1212 are disconnected by the first notch 1214, and the upper ends of the first edge wing 1211 and the second edge wing 1212 are connected to form an integral structure by the first arc wall 1213. Therefore, the lower ends of the first edge wing 1211 and the second edge wing 1212 have lower structural strength than the upper ends and are more susceptible to elastic deformation.

[0058] like Figure 5 As shown, the base 111 is provided with first clamping parts 1112 on both sides corresponding to the first edge wing 1211 and the second edge wing 1212, and second clamping parts 1215 are provided on the first edge wing 1211 and the second edge wing 1212, respectively. One of the first clamping parts 1112 and the second clamping parts 1215 is a clamping protrusion, and the other is a clamping groove. In addition, the first clamping part 1112 is provided at one end of the first edge wing 1211 and the second edge wing 1212 away from the first arc wall 1213. When the abutting member 110 is plugged into the housing member 120, the first edge wing 1211 and the second edge wing 1212 are spread apart to increase the elastic deformation distance of the first edge wing 1211 and the second edge wing 1212, so that the first clamping part 1112 and the second clamping part 1215 can be clamped. Then, the pulling force on the first edge wing 1211 and the second edge wing 1212 is released to restore their elastic deformation, so that the abutment member 110 and the shell member 120 form an integral structure through snap connection.

[0059] The second aspect of the present application also proposes a liquid reservoir assembly, which includes the liquid level sensor installation structure mentioned in any of the above embodiments, and can quickly realize the installation and removal of the liquid level sensor 100, thereby facilitating improving the efficiency of organ transplantation operations.

[0060] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
