[0001] The disclosed embodiments of the present application relate to the technical field of medical equipment, and more particularly, to an infusion tube clamp. BACKGROUND
[0002] Infusion is a common medical treatment in medical scenarios. Generally, in order to ensure the safety and effectiveness of infusion, medical staff need to manage the infusion.
[0003] Although some medical devices in the prior art also support monitoring of infusion pipelines, these medical devices are usually large in size and complex in structure. CONTENT OF THE UTILITY MODEL
[0004] According to the embodiments of the present application, an infusion tube clamp is provided, which can minimize the size of the infusion tube clamp and reduce the structural complexity of the infusion tube clamp.
[0005] The first aspect of the present application discloses an infusion tube clamp, comprising a clamping arm and an ultrasonic module, the clamping arm at least comprising a first clamping part and a second clamping part, the first clamping part and the second clamping part each being provided with a sub-end face for aligning an infusion tube on the end face facing each other, the second clamping part comprising a first end part and a second end part connected to each other, the first end part being higher than the second end part, the first end part being provided with a notch part at the position higher than the second end part, the first clamping part comprising a third end part and a fourth end part connected to each other, the second end part and the fourth end part each being used for clamping the infusion tube, the third end part being rotatably connected to the first end part in the notch part; the ultrasonic module comprising a plurality of groups of transceivers, the transmitters in the plurality of groups of transceivers being arranged on the first clamping part, and the transmitting part of the transmitter for transmitting ultrasonic signals being exposed to at least the sub-end face, the receivers in the plurality of groups of transceivers being arranged on the second clamping part, and the receiving part of the receiver for receiving ultrasonic signals being exposed to at least the sub-end face.
[0006] Therefore, the infusion tube clamp comprises a clamping arm and an ultrasonic module, the clamping arm at least comprising a first clamping part and a second clamping part, the first clamping part and the second clamping part each being provided with a sub-end face for aligning an infusion tube on the end face facing each other, the ultrasonic module comprising a plurality of groups of transceivers, the transmitters in the plurality of groups of transceivers each being arranged on the first clamping part, and the transmitting part of the transmitter for transmitting ultrasonic signals being exposed to at least the sub-end face, the receivers in the plurality of groups of transceivers each being arranged on the second clamping part, and the receiving part of the receiver for receiving ultrasonic signals being exposed to at least the sub-end face, since the second clamping part comprises a first end part and a second end part connected to each other, the first end part being higher than the second end part, the first end part being provided with a notch part at the position higher than the second end part, the first clamping part comprising a third end part and a fourth end part connected to each other, the second end part and the fourth end part each being used for clamping the infusion tube, the third end part being rotatably connected to the first end part in the notch part, which can help to reduce the size of the clamping arm and reduce the structural complexity of the clamping arm.
[0007] At least one of the first clamping part and the second clamping part is provided with a recess at the sub-end surface for accommodating the infusion tube, so as to align the sub-end surface with the infusion tube.
[0008] Therefore, at least one of the first clamping part and the second clamping part is provided with a recess at the sub-end surface for accommodating the infusion tube, so as to align the sub-end surface with the infusion tube, and the clamping reliability of the infusion tube clamp can be improved through the recess.
[0009] The first clamping part and the second clamping part are both provided with a recess at the sub-end surface.
[0010] Therefore, the first clamping part and the second clamping part are both provided with a recess at the sub-end surface, so that the first clamping part and the second clamping part can both form reliable clamping on the infusion tube.
[0011] The signal transmission direction of at least one group of transceivers is perpendicular to the extension direction of the sub-end surface, and the signal transmission direction of at least one group of transceivers is inclined to the extension direction of the sub-end surface.
[0012] Therefore, by setting the signal transmission direction of at least one group of transceivers perpendicular to the extension direction of the sub-end surface, and the signal transmission direction of at least one group of transceivers inclined to the extension direction of the sub-end surface, the transceiver groups with different signal transmission directions can provide the medical staff with the flow situation in the infusion tube from different aspects.

[0017] The second clamping part is internally provided with a containing space, and the infusion tube clamp further comprises a sensor arranged in the containing space, which is used for sensing the diameter of the infusion tube clamped by the clamping arm.
[0018] Therefore, the containing space is arranged in the second clamping part to contain the sensor for sensing the diameter of the infusion tube clamped by the clamping arm, so as to further provide assistance for the infusion management of medical staff.
[0019] The first end part is internally further provided with a containing space.
[0020] Therefore, the containing space is arranged in the first end part which is higher than the second end part, so as to increase the volume of the containing space and facilitate the accommodation of devices with large sizes in the containing space as much as possible.
[0021] The second end part and the fourth end part are of the same shape.
[0022] Therefore, the second end part and the fourth end part are arranged to be of the same shape, which helps to reduce the structural complexity of the clamping arm. BRIEF DESCRIPTION OF DRAWINGS

[0029] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application will be further described in detail below in conjunction with the drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0030] Please refer to Figure 1 and Figure 2 ,Figure 1 This is a schematic diagram of an embodiment of the infusion tubing clamp of this application. Figure 2 This is a schematic diagram of another embodiment of the infusion tubing clamp of this application. (See attached diagram.) Figure 1 and Figure 2 The infusion clamp 10 includes a clamping arm 11 and an ultrasonic module 12. The clamping arm 11 includes at least a first clamping part 111 and a second clamping part 112. The end faces A of the first clamping part 111 and the second clamping part 112 facing each other are each provided with a sub-end face A1 for aligning the infusion tube. The ultrasonic module 12 includes several transceivers 121. A transmitter T among the several transceivers 121 is located in the first clamping part 111 and is used to transmit ultrasonic signals (due to the transmission of ultrasonic signals through...). Figure 1 (As shown in the observation angle, the transmitting part is blocked by the first clamping part 111 and is therefore not shown) at least exposed on the sub-end face A1. The receiver R of the plurality of transceivers 121 is disposed on the second clamping part 112 and the receiver R' used to receive ultrasonic signals is at least exposed on the sub-end face A1.
[0031] In one implementation scenario, a silicone strip can be attached to the sub-end face A1, with the silicone strip extending in the same direction as the infusion tube, so as to align the infusion tube through the silicone strip.
[0032] In one implementation scenario, as another possible implementation method, such as Figure 1 As shown, at least one of the first clamping part 111 and the second clamping part 112 has a recess (not shown) at the sub-end face A1 for accommodating the infusion tube, so as to align the infusion tube at the sub-end face A1.
[0033] In a specific implementation scenario, please refer to [the relevant documentation]. Figure 1 The direction of the recess can be the same as the direction of the infusion tube.
[0034] In a specific implementation scenario, a recess for accommodating the infusion tube may be provided only at the sub-end face A1 of the first clamping part 111.
[0035] In another specific implementation scenario, a recess for accommodating the infusion tube may be provided only at the sub-end face A1 of the second clamping part 112.
[0036] In another specific implementation scenario, a recess for accommodating the infusion tube can be provided at the sub-end face A1 of both the first clamping part 111 and the second clamping part 112.
[0037] In one implementation scenario, the signal transmission direction of at least one set of transceivers 121 can be perpendicular to the extension direction of the sub-end face A1, i.e. the extension direction of the infusion tube, and the signal transmission direction of at least one set of transceivers 121 can be inclined to the extension direction of the sub-end face A1, i.e. the extension direction of the infusion tube.
[0038] In one specific implementation scenario, as shown in FIG. 1B, the plurality of transceiver groups 121 can include a first transmitter T1 and a second transmitter T2 disposed on the first clamping portion 111, and a first receiver R1 and a second receiver R2 disposed on the second clamping portion 112. The signal transmission direction between the first transmitter T1 and the first receiver R1 (as shown by the dashed line between the first transmitter T1 and the first receiver R1 in FIG. 1B) is perpendicular to the extension direction, and the signal transmission direction between the second transmitter T2 and the second receiver R2 (as shown by the dashed line between the second transmitter T2 and the second receiver R2 in FIG. 1B) is inclined to the extension direction. Figure 2 Figure 2 In one specific implementation scenario, as shown in FIG. 1B, the plurality of transceiver groups 121 can include a first transmitter T1 and a second transmitter T2 disposed on the first clamping portion 111, and a first receiver R1 and a second receiver R2 disposed on the second clamping portion 112. The signal transmission direction between the first transmitter T1 and the first receiver R1 (as shown by the dashed line between the first transmitter T1 and the first receiver R1 in FIG. 1B) is perpendicular to the extension direction, and the signal transmission direction between the second transmitter T2 and the second receiver R2 (as shown by the dashed line between the second transmitter T2 and the second receiver R2 in FIG. 1B) is inclined to the extension direction. Figure 2
[0039] In one specific implementation scenario, as shown in FIG. 1B, the plurality of transceiver groups 121 can include a first transmitter T1 and a second transmitter T2 disposed on the first clamping portion 111, and a first receiver R1 and a second receiver R2 disposed on the second clamping portion 112. The signal transmission direction between the first transmitter T1 and the first receiver R1 (as shown by the dashed line between the first transmitter T1 and the first receiver R1 in FIG. 1B) is perpendicular to the extension direction, and the signal transmission direction between the second transmitter T2 and the second receiver R2 (as shown by the dashed line between the second transmitter T2 and the second receiver R2 in FIG. 1B) is inclined to the extension direction. Figure 3 Figure 3 Figure 3
[0040] In one specific implementation scenario, as shown in FIG. 1B, the plurality of transceiver groups 121 can include a first transmitter T1 and a second transmitter T2 disposed on the first clamping portion 111, and a first receiver R1 and a second receiver R2 disposed on the second clamping portion 112. The signal transmission direction between the first transmitter T1 and the first receiver R1 (as shown by the dashed line between the first transmitter T1 and the first receiver R1 in FIG. 1B) is perpendicular to the extension direction, and the signal transmission direction between the second transmitter T2 and the second receiver R2 (as shown by the dashed line between the second transmitter T2 and the second receiver R2 in FIG. 1B) is inclined to the extension direction.
[0041] It should be noted that the above examples are merely several possible combinations of the transceivers 121, and are not limited herein. In the following, the ultrasonic signals of different groups of transceivers 121 are briefly described by taking the auxiliary exhaust detection and the auxiliary flow rate detection as examples, so as to facilitate the understanding of the technical mechanism of the different groups of transceivers 121. For the transceivers 121 whose signal transmission direction is perpendicular to the extension direction of the sub-end surface A1, there is a significant difference in the energy level of the ultrasonic signals received by the receiver R in the transceiver 121 when there is a bubble in the infusion tube and when there is no bubble, so as to reflect whether the exhaust is completed. In one possible example, the energy level of the ultrasonic signals received by the receiver R can be directly outputted to assist in judging whether the exhaust is completed, or in another possible example, a comparator or the like can be further arranged to input the energy level of the ultrasonic signals received by the receiver R to the comparator, and the comparator outputs the comparison result between the energy level and a preset level to assist in judging whether the exhaust is completed. For the transceivers 121 whose signal transmission direction is inclined to the extension direction of the sub-end surface A1, there is a Doppler shift between the ultrasonic signals received by the receiver R and the ultrasonic signals emitted by the transmitter T in the transceiver 121 due to the influence of the liquid flow rate in the infusion tube, so as to reflect the liquid flow rate. In one possible example, the Doppler shift can be directly outputted to assist in judging the liquid flow rate. Of course, the above examples are merely several possible examples of the infusion tube clamp 10 of the present application for assisting in infusion. The infusion tube clamp 10 of the present application can be developed into various facilities, which are not exemplified one by one herein.
[0042] In one implementation scenario, the clamping arm 11 further comprises a rotating shaft 113, and a resilient member (not shown) arranged on the rotating shaft and connected to the first clamping part 111 and the second clamping part 112, and the first clamping part 111 and the second clamping part 112 are elastically pivoted to each other through the rotating shaft 113 and the resilient member. Of course, the above example is merely one possible example of the resilient rotatable connection of the first clamping part 111 and the second clamping part 112, and other possible implementation manners are not limited thereby. For example, the resilient rotatable connection can also be realized by arranging magnetic members with opposite magnetism on the first clamping part 111 and the second clamping part 112 instead of the aforementioned resilient member. The other examples are not exemplified one by one herein.
[0043] In one embodiment, the second clamping portion 112 is internally provided with a receiving space (not shown), and the infusion tube clamp 10 further comprises a sensor (not shown) arranged in the receiving space, for sensing the diameter of the infusion tube clamped by the clamping arm 11. As one possible example, the sensor can comprise a pressure sensor, for sensing the change of the elastic force of the elastic member, so as to infer the opening angle between the first clamping portion 111 and the second clamping portion 112, and thus estimate the diameter of the infusion tube. Of course, the above example is merely one possible example of sensing the diameter, and does not limit the sensing of the diameter by other kinds of sensors, which will not be exemplified one by one herein.

[0045] In one specific embodiment, the first end portion 1121 is internally further provided with a receiving space (not shown). Exemplarily, the receiving space can be used for accommodating the aforementioned sensor. Of course, the receiving space can also be used for accommodating other devices, which will not be exemplified one by one herein.
[0046] In one specific embodiment, please continue to refer to Figure 4 , the second end portion 1122 and the fourth end portion 1112 are identical in shape. For example, the second end portion 1122 and the fourth end portion 1112 can both be provided with a recess portion at the sub-end surface A1.
[0047] In one embodiment, please refer to Figure 5 , Figure 5 is a structural schematic diagram of an embodiment of the infusion tube clamp of the present application. As shown in Figure 5As shown, the infusion tube can be connected to an infusion device, which can include but is not limited to an infusion pump and the like. An infusion tube clamp 10 can be arranged at the liquid outlet end of the infusion tube, and an infusion tube clamp 10 can also be arranged at the liquid inlet end of the infusion tube. It should be noted that the liquid outlet end is the end of the infusion tube close to the infusion device, and the liquid inlet end is the end of the infusion tube away from the infusion device. In the above manner, the infusion tube clamp 10 can perform ultrasonic detection on the infusion tube at both the liquid outlet end and the liquid inlet end. Of course, in actual application, it can also not be limited to this, such as also arranging the infusion tube clamp 10 at the middle segment of the infusion tube, and the like, which will not be enumerated one by one here.
