Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a detection device for negative pressure suction clamping. Background Technology

[0002] In clinical practice, when monitoring physiological parameters of internal cavities for extended periods, it is necessary to clamp and fix the monitoring device, such as a capsule, into the body. There are two main methods of clamping and fixing: one is to use titanium clips to clamp the capsule through an electronic gastroscope; the other is to use a capsule with its own clamping and delivery mechanism, which then uses negative pressure to draw the mucosa into the clamping hole for clamping.

[0003] However, in the existing technology, the negative pressure suction clamping device is a blind operation, which cannot effectively determine whether the adsorption is in place and whether the clamping is successful, thus affecting the success rate of the clamping operation.

[0004] In summary, how to detect whether the negative pressure suction clamping device has successfully clamped is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a detection device for negative pressure suction clamping. The device has a simple structure and can detect whether the adsorption chamber has successfully adsorbed, thereby detecting whether the clamping component has successfully clamped.

[0006] To achieve the above objectives, this application provides a detection device for negative pressure suction clamping, comprising:

[0010] The acquisition component is electrically connected to the first electrode plate and the second electrode plate, and is used to detect whether the adsorption cavity has successfully adsorbed, so as to detect whether the clamping component has successfully clamped.

[0011] Preferably, the acquisition component is used to acquire the impedance or capacitance value between the first electrode sheet and the second electrode sheet, and to compare the impedance or capacitance value with a preset value to detect whether the adsorption chamber has successfully adsorbed the material.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This application provides a detection device for negative pressure suction clamping, including a clamping assembly 10, a first electrode plate 20, a second electrode plate 30, and a data acquisition assembly 40. The clamping assembly 10 has an adsorption cavity 11; the first electrode plate 20 is disposed in the adsorption cavity 11; the second electrode plate 30 is disposed in the adsorption cavity 11 and spaced apart from the first electrode plate 20; the data acquisition assembly 40 is electrically connected to the first electrode plate 20 and the second electrode plate 30, and is used to detect whether the adsorption cavity 11 has successfully adsorbed the material, thereby detecting whether the clamping assembly 10 has successfully clamped the material.

[0033] The aforementioned clamping assembly 10 is existing technology, used to clamp and fix a monitoring device, such as a capsule, into the body. It has a clamping seat with an adsorption cavity 11, which adsorbs the mucosa through negative pressure.

[0034] The specific operation is as follows: When using the capsule, the capsule is fixed on the clamping assembly 10 and transported into the esophagus by the conveyor. Then, the esophageal mucosa is adsorbed into the adsorption chamber 11 by negative pressure. The conveyor controls the clamping structure in the clamping assembly 10 to clamp the esophageal mucosa, thereby fixing the capsule to the esophageal wall.

[0035] In the embodiments of this application, the acquisition component 40 is used to acquire the impedance value or capacitance value between the first electrode plate 20 and the second electrode plate 30, and to compare the impedance value or capacitance value with a preset value to detect whether the adsorption chamber 11 has successfully adsorbed.

[0036] During signal transmission, there are two main transmission routes, and both routes can be used to detect whether adsorption has been successful.

[0037] One approach involves generating a capacitance value between the first electrode 20 and the second electrode 30. During the adsorption process, if any mucous membrane is adsorbed into the adsorption chamber 11, the capacitance value between the first electrode 20 and the second electrode 30 will change. The acquisition component 40 acquires the capacitance value and compares it with a preset value to detect whether the adsorption chamber 11 has successfully adsorbed the membrane. When the capacitance value reaches the preset value, it can be determined that the adsorption is in place. This information is then fed back to the operator, who can then perform the clamping operation. After the operation is completed, the capacitance value fluctuates within a certain range, and the clamping success can be confirmed by checking the range of the capacitance value.

[0038] Another approach involves generating an impedance value between the first electrode 20 and the second electrode 30. During the adsorption process, if any mucous membrane is adsorbed into the adsorption chamber 11, the impedance value between the first electrode 20 and the second electrode 30 will change. The acquisition component 40 acquires the impedance value and compares it with a preset value to detect whether the adsorption chamber 11 has successfully adsorbed the membrane. When the impedance value reaches the preset value, it can be determined that the adsorption is in place. This information is then fed back to the operator, who can then perform the clamping operation. After the operation is completed, the impedance value fluctuates within a certain range, and the clamping success can be confirmed by checking the range of the impedance value.

[0039] The aforementioned preset values ​​were set based on physiological parameters collected clinically.

[0040] In embodiments of this application, the acquisition component 40 includes a circuit board 41, a signal transmitting module, a signal acquisition module, and a detection module. The signal transmitting module is mounted on the circuit board 41 and connected to the first electrode 20 for transmitting detection signals. The signal acquisition module is mounted on the circuit board 41, spaced apart from the signal transmitting module, and connected to the second electrode 30 for acquiring detection signals transmitted via the first electrode 20 and the second electrode 30. The detection module is mounted on the circuit board 41, spaced apart from the signal acquisition module, and connected to the signal acquisition module for receiving and processing detection signals to detect whether the adsorption chamber 11 has successfully adsorbed the signal.

[0041] In other words, during operation, the circuit board 41 sends a detection signal to one of the electrode plates and receives a feedback signal through the other electrode plate. This signal changes before and after the mucosa is inhaled. After being processed by the circuit board 41, it is compared with a preset value to detect whether the adsorption chamber 11 has successfully adsorbed the mucosa.

[0042] In embodiments of this application, the acquisition component 40 further includes a housing 42 and a plug-in clamping component 10 for mounting a circuit board 41 to seal the circuit board 41.

[0043] Specifically, the circuit board 41 is disposed inside the housing 42, and one end of the housing 42 has an opening for insertion into the clamping assembly 10 so that the housing 42 forms a sealed space, thereby sealing the circuit board 41. At the same time, the circuit board 41 is connected to two electrode plates through wires 50.

[0044] In the embodiments of this application, the first electrode sheet 20 and the second electrode sheet 30 are both vertically connected to the inner wall of the adsorption cavity 11, and the two are arranged in parallel.

[0045] In the embodiments of this application, the first electrode sheet 20 is disposed at the bottom of the adsorption cavity 11, and the second electrode sheet 30 is disposed on the side wall of the adsorption cavity 11, and the two are arranged perpendicularly.

[0046] In the embodiments of this application, the first electrode sheet 20 is disposed at the bottom of the adsorption cavity 11, and the second electrode sheet 30 is disposed at the top of the adsorption cavity 11, and the two are arranged in parallel.

[0047] In the embodiments of this application, the first electrode plate 20 and the second electrode plate 30 are respectively connected to the two ends of the circuit board 41 via wires 50.

[0048] Of course, in practice, there is no limitation on the installation position of the first electrode plate 20 and the second electrode plate 30, as long as a circuit is formed between the circuit board 41 and the first electrode plate 20 and the second electrode plate 30.

[0049] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0050] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
