Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a medical balloon perfusion system and a medical system. Background Art

[0002] Percutaneous coronary intervention (PCI) is mainly used for the treatment of obstructive coronary artery disease and has developed rapidly due to its advantages of minimally invasive, time-saving, safe and efficient. However, in some cases, coronary artery obstruction may lead to abnormalities in the coronary microcirculation system, and then cause a part of the myocardium to enter a dormant, false death or even death state, resulting in severe acute myocardial infarction.

[0003] The abnormality of coronary microcirculation cannot be treated by conventional PCI surgery. The existing conventional treatment method is to block the blood flow of the coronary sinus, increase the blood vessel pressure, so that the blood flow returns to perfuse into the microcirculation system. With the increase of pressure, the refluxed blood also plays a role in flushing. The main execution device of this treatment method is the coronary sinus microcirculation perfusion system, which includes a pressurizing device and a balloon catheter. The balloon of the balloon catheter is placed into the coronary sinus, and the balloon is repeatedly filled and deflated by the pressurizing device to intermittently block the coronary sinus by using the balloon, so as to achieve the effect of blood reflux and flushing.

[0004] The pressurizing device of the coronary sinus microcirculation perfusion system in the prior art includes a reusable air pump and a gas cylinder. The environmental cleanliness of the air pump and the loss of the gas cylinder are problems that cannot be ignored in the current design. For reusable devices, maintaining environmental hygiene requires regular disassembly for cleaning and sterilization. Otherwise, once the balloon ruptures in the body, the dust and bacteria remaining in the device will enter the human body. In order to improve the safety of reuse and simplify the enclosure, it is a common method to separate at least some of the components that need to be maintained and use them as disposable consumables. In order to maintain the effective cooperation between the reusable device end and the separated consumable end, most control units must be partially integrated into the consumable end to maintain the monitoring of the consumable end. However, integrating the control components into the consumable end results in a relatively high cost of the consumables, and frequently replacing the consumables will continuously challenge the reliability of the interfaces between the control components on the consumable end and the control components on the device end.

[0045] To make the objectives, advantages, and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the objectives of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0046] Figure 1 is a schematic diagram of the framework of the medical balloon perfusion device 10 provided by some embodiments of the present invention. Figure 2 is a schematic diagram when the medical balloon perfusion system 10 cooperates with the balloon catheter 20 to form a medical system. As Figure 1 andFigure 2 As shown, the medical balloon perfusion system 10 includes a first component 100 and a second component 200. The first component 100 includes a medium storage part 110 and an execution unit 120. The second component 200 includes an electrical signal acquisition unit 210, a driving unit 220, and a control unit 230.

[0047] The medium storage part 110 has an inner cavity 111, and the inner cavity 111 at least partially constitutes a medium storage space 112. The execution unit 120 is connected to the medium storage part 110. The electrical signal acquisition unit 210 is used to acquire a first target signal related to the first component 100. The driving unit 220 is in transmission connection with the execution unit 120 and is detachably connected to achieve the detachable connection between the second component 200 and the first component 100. The control unit 230 is connected to the electrical signal acquisition element 210 and the driving unit 220, and is configured to control the operation of the driving unit 220 according to the first target signal, and further drive the execution unit 120 to move relative to the medium storage part 110 to change the volume of the medium storage space 112.

[0048] Those skilled in the art can understand that the balloon catheter 20 includes a balloon 300 and a tube mechanism 400. The balloon 300 is hermetically connected to the outer peripheral surface of the distal end of the tube mechanism 400, and a medium channel (not shown in the figure) communicating with the balloon 300 is formed on the tube mechanism 400. The proximal end of the tube mechanism 400 is connected to the medium storage part 110, and the medium channel is also communicated with the medium storage space 112. When the execution unit 120 moves relative to the medium storage part 210 under the drive of the driving unit 220 so that the volume of the medium storage space 112 decreases, the medium stored in the medium storage space 112 is pushed and enters the balloon 300 along the medium channel, so that the balloon 300 is filled; when the execution unit 120 moves relative to the medium storage part 110 under the drive of the driving unit 220 so that the volume of the medium storage space 112 increases, the medium in the balloon 300 is drawn back into the medium storage space 112 through the medium channel, so that the balloon 300 is depressurized. That is, the medical balloon perfusion system 10 can be used to fill or depressurize the balloon 300.

[0049] The medical system can be used for the perfusion of the coronary sinus microcirculation. Specifically, the balloon 300 is placed into the coronary sinus of a patient, and the medical balloon perfusion system 10 is used to repeatedly switch the balloon 300 between the filled and depressurized states, so as to intermittently block the coronary sinus with the filled balloon 300, so that the blood flow in the coronary sinus refluxes and flushes the coronary vein.

[0050] In the medical balloon perfusion system 10 provided by the embodiment of the present utility model, all control components (i.e., the control unit 230) and electrical components for collecting electrical signals (i.e., the electrical signal acquisition unit 210) are arranged on the second component 200. The first component 100 does not involve any expensive electrical components and control components. Thus, when the first component 100 is used as a replaceable consumable, the price of the consumable is greatly reduced. Moreover, when replacing the first component 100, there is no need to disassemble and assemble electrical components and control components, avoiding the failure problem caused by repeated disassembly and assembly of the interface parts of electrical components and control components.

[0051] Since the first component 100 is detachably connected to the second component 200, the drive unit 220 can only drive the execution unit 120 to move relative to the medium storage part 110 to fill or deflate the balloon 300 when the first component 100 is in transmission connection with the second component 200. Therefore, the first target signal includes a first position signal characterizing the connection between the first component 100 and the second component 200.

[0052] It can be understood that in an actual surgical scenario, the operator determines the filling pressure of the balloon 300 according to the actual situation of the patient, and then determines the volume of the medium pushed into the balloon 300. For the convenience of description, in this article, the value of the determined filling pressure is called the first preset value, and the value of the determined volume of the medium pushed into the balloon 300 is called the second preset value. To enable the medical balloon perfusion system 10 to provide enough medium so that the filling pressure of the balloon 300 can reach the first preset value, it is required that when the balloon 300 is in a deflated state, the volume of the medium stored in the medium storage part 110 should be greater than or equal to the second preset value. Correspondingly, when the balloon 300 is in a deflated state, the volume of the medium storage space 112 should be greater than or equal to the second preset value. In this article, the volume of the medium storage space 112 when the balloon 300 is in a deflated state is called the first predetermined volume, and the first predetermined volume is greater than or equal to the second preset value. Therefore, the first target signal further includes a third position signal characterizing that the medium storage space 112 has the first predetermined volume.

[0053] In a further solution, the first target signal may further include other position signals such as the fourth position signal described later.

[0054] Next, a further introduction to the specific configuration of the medical balloon perfusion system 10 will be made. It should be noted that the following description is only based on the optional embodiments of the medical balloon perfusion device 10, and should not unduly limit the present utility model.

[0055] Optionally, as Figure 2 shown, the driving unit 220 includes a motor 221, a speed reducer 222, and an output shaft 223 that are connected in sequence. The output shaft 223 constitutes the output end of the driving unit 220 and is used for driving and detachably connecting to the execution unit 120. In practice, the output shaft 223 can be a coupling.

[0056] Please continue to refer to Figure 2 and in combination with Figure 3 , the medium storage portion 110 is a hollow structure having the inner cavity 111. The medium storage portion 110 is further provided with a joint hole 113 that communicates with the inner cavity 111 and is used for connecting to the balloon catheter 20. The execution unit 120 includes a pushing portion 121, a piston rod 122, and a transmission mechanism 123. The pushing portion 121 is disposed within the inner cavity 111, is connected to the wall of the inner cavity 111, and is capable of moving axially along the joint hole 113 to approach or move away from the joint hole 113. The surface of the pushing portion 121 that approaches the joint hole 113 and the inner wall of the medium storage portion 110 together define the medium storage space 112. The piston rod 122 extends axially along the joint hole 113, and one end of the piston rod 122 that approaches the joint hole 113 is connected to the pushing portion 121, and the other end of the piston rod 122 that is away from the joint hole 113 extends outside the medium storage portion 110. The transmission mechanism 123 includes an input shaft 1231, a gear 1232, and a rack 1233. The input shaft 1231 is detachably connected to the output end (i.e., the output shaft 223) of the driving unit 220. The gear 1232 is sleeved on the input shaft 1231 and remains axially stationary relative to the input shaft 1231. The rack 1233 is disposed on the piston rod 122 and extends axially along the joint hole 113, and the rack 1233 meshes with the gear 1232.

[0057] In a preferred embodiment, a first engaging portion 2231 is formed at one end of the output shaft 223 away from the reducer 222, and a second engaging portion 12311 is provided on the input end of the input shaft 1231, and one of the second engaging portion 12311 and the first engaging portion 2231 is an engaging groove, and the other is an engaging protrusion, and the engaging protrusion and the engaging groove are connected in a pluggable manner. That is, when the engaging protrusion is at least partially inserted into the engaging groove, and the output shaft 223 and the input shaft 1231 remain relatively stationary, the execution unit 120 is in transmission connection with the driving unit 220, and when the engaging protrusion is pulled out of the engaging groove and completely located outside the engaging groove, the execution unit 120 is disconnected from the driving unit 220.

[0058] It can be understood that the cross-section of the engagement protrusion is a non-circular shape, such as a triangle, a quadrilateral, a pentagon, a hexagon, etc., and the shape of the cross-section of the engagement groove matches the shape of the cross-section of the engagement protrusion.

[0059] Further, the first component 100 may further include a first housing 130, the medium storage unit 110 is at least partially disposed in the first housing 130, and the execution unit 120 is also at least partially disposed in the first housing 130. The second component 200 may further include a second housing 240, the electrical signal acquisition unit 210 is at least partially disposed in the second housing 240, the control unit 230 is at least partially disposed in the second housing 240, and the drive unit 220 is at least partially disposed in the second housing 240. In some embodiments, when the first engaging portion 2231 is the engaging protrusion and the second engaging portion 12311 is the engaging groove, it is preferred that the execution unit 120 is entirely located in the first housing 130, and the first engaging portion 2231 is located outside the second housing 240.

[0060] Optionally, refer to Figure 3 and Figure 4, the electrical signal acquisition unit 210 includes a bonding signal acquisition part (not labeled in the figure), and the bonding signal acquisition part includes two second conductive members 211. One end of each second conductive member 211 is electrically connected to the control unit 230, and the other end extends to the outside of the second housing 240 and is used to contact the first conductive member 140. For the convenience of description, in this article, the end of the second conductive member 211 used to contact the first conductive member 140 is called the free end. The first assembly 100 further includes a first conductive member 140, and the first conductive member 140 can be arranged at any suitable position, for example, arranged on the first housing 130. The medical balloon perfusion system 10 is configured such that when the first conductive member 140 is in contact with the free end of the second conductive member 211 when the execution unit 120 is in transmission connection with the drive unit 220, the control unit 230, the bonding signal acquisition part, and the first conductive member 140 form a closed loop; and when the first conductive member 140 is separated when the execution unit 120 and the drive unit 220 are disconnected, the control unit 230, the bonding signal acquisition part, and the first conductive member 140 form an open circuit. Conversely, when the first conductive member 140 is in contact with the free end of the second conductive member 211 so that the control unit 230, the bonding signal acquisition part, and the first conductive member 140 form a closed loop, the execution unit 120 is connected to the drive unit 220, and when the first conductive member 140 is separated from the free end of the second conductive member 211 so that the control unit 230, the bonding signal acquisition part, and the first conductive member 140 form an open circuit, the execution unit 120 is disconnected from the drive unit 220.

[0061] In other words, it is possible to judge whether the execution unit 120 is connected to or separated from the drive unit 220 based on the on / off state of the circuit formed by the control unit 230, the bonding signal acquisition part, and the first conductive member 140. It can be understood that when the circuit formed by the control unit 230, the bonding signal acquisition part, and the first conductive member 140 becomes a closed loop, current flows through the bonding signal acquisition part and the first conductive member 140, and when the circuit formed by the control unit 230, the bonding signal acquisition part, and the first conductive member 140 is open, no current flows through the bonding signal acquisition part and the first conductive member 140. Therefore, the current signal flowing through the bonding signal acquisition part and the first conductive member 140 can be used as the first position signal.

[0062] It can be understood that the second conductive member 211 should have a certain hardness and is not easily bent. The first conductive member 140 is generally made of metal and can have any suitable shape and size.

[0063] In a preferred embodiment, the number of the joint signal acquisition parts and the number of the first conductive members 140 are both plural. The plural first conductive members 140 can be arranged on the first housing 130 and located in different planes. The plural first conductive members 140 correspond to the plural joint signal acquisition parts one by one, so that the free end of the second conductive member 211 of each joint signal acquisition part is used to contact one of the first conductive members 140. When the joint protrusion is inserted into the joint groove to a predetermined depth so that the execution unit 120 is connected to the driving unit 220, the second conductive member 211 of each joint signal acquisition part contacts the corresponding first conductive member 140 respectively. When the joint protrusion is pulled out of the joint groove and completely located outside the joint groove, the second conductive member 211 of each joint signal acquisition part is separated from the corresponding first conductive member 140 respectively. The reason for such a setting is that when the execution unit 120 and the driving unit 220 are detached, the driving unit 220 should stop operating. The joint protrusion has a certain length in its axial direction, and the joint groove has a certain depth in its axial direction. During the process of detaching the execution unit 120 from the driving unit 220, there is a situation where although the joint protrusion is no longer firmly inserted at the joint groove, but it is still partially located in the joint groove. At this time, if the driving unit 220 operates, it may cause a failure of the driving unit 220. By providing the plural first conductive members 140 and the plural joint signal acquisition parts and reasonably designing the positions of the first conductive members 140, the occurrence of this problem can be effectively avoided.

[0064] In a specific example, the piston rod 122 extends in the horizontal direction, the gear 1232 is disposed above the rack 124, and when the input shaft 1231 extends in the horizontal direction perpendicular to the piston rod 122, the number of the first conductive members 140 can be two. One of the first conductive members 140 can be disposed on the side surface of the second housing 230 facing the first assembly 10, and the other first conductive member 140 can be disposed on the upper surface or the lower surface of the second housing 230. Correspondingly, the number of the engagement signal acquisition parts is two, and the second conductive members 211 of the engagement signal acquisition parts extend along the extension direction of the input shaft 1231. In this way, when the engagement protrusion is inserted into a predetermined depth in the engagement groove, the second conductive members 211 of the two engagement signal acquisition parts are respectively in contact with the two first conductive members 140. When the execution unit 120 is detached from the drive unit 220, during the process of pulling out the engagement protrusion from the engagement groove, the first conductive member 140 on the side surface of the second housing 230 facing the first assembly 10 is separated from the corresponding second conductive member 211 first, and the other first conductive member 140 is separated from the corresponding second conductive member 211 later.

[0065] In some embodiments, the cooperation between the first assembly 100 and the second assembly 200 also has a directionality, that is, the first assembly 100 and the second assembly 200 must be assembled in a preset direction to enable the transmission connection between the execution unit 120 and the output shaft 223. As described above, the cross sections of both the first engagement portion 2231 and the second engagement portion 1231 are non-circular shapes. Therefore, when assembling the first assembly 100 and the second assembly 200, the output shaft 223 should also be in a predetermined state so that the first engagement portion 2231 can be docked with the second engagement portion 12311.

[0066] The predetermined state described here refers to the arrangement of the first component 100 and the second component 200 according to the preset direction, and when the input shaft 1231 is coaxial with the output shaft 223, the projection of the first joint portion 2231 on a plane perpendicular to the axis of the output shaft 223 coincides with the projection of the second joint portion 1231 on a plane perpendicular to the axis of the input shaft 1231. Thus, the electrical signal acquisition unit 210 is also configured to acquire a second target signal related to the second component 200, and the second target signal includes a second position signal indicating that the output shaft 223 is in the predetermined state. That is, when the electrical signal acquisition unit 210 acquires the second position signal, it indicates that the output shaft 223 is in the predetermined state. It can be understood that when the electrical signal acquisition unit 210 does not acquire the second position signal, the control unit 230 will control the drive unit 220 to operate until the output shaft 223 is in the predetermined state (that is, the electrical signal acquisition unit 210 acquires the second position signal).

[0067] like Figure 6 and Figure 7 As shown, the electrical signal acquisition unit 210 also includes a first sensor 212, and the first sensor 212 is used to obtain the second position signal. Specifically, when the first sensor 212 receives the monitoring signal emitted by itself, the first sensor 212 obtains the second position signal. In an optional embodiment, the first sensor is a photoelectric sensor, and the corresponding monitoring signal is an optical signal.

[0068] In an optional embodiment, the output shaft 223 is provided with a first signal transmission hole 2232, and the first sensor 212 is arranged corresponding to the first signal transmission hole 2232. During the rotation of the output shaft 223, the first sensor 212 is aligned with or staggered from the first signal transmission hole 2232. When the first sensor 212 is aligned with the first signal transmission hole 2232, the monitoring signal emitted by the first sensor 212 can be transmitted through the first signal transmission hole 2232 and then received by the first sensor 212; when the first sensor 212 is staggered from the first signal transmission hole 2232, the first sensor 212 cannot receive the monitoring signal emitted by itself.

[0069] Specifically, please refer to Figure 6, the first signal transmission hole 2232 passes through the output shaft 223, and the axis of the first signal transmission hole 2232 is not in the same plane as the axis of the output shaft 223. Furthermore, the axis of the first signal transmission hole 2232 is also perpendicular to the axis of the output shaft 223. The first sensor 212 includes a first monitoring signal transmitting unit 2121 and a first monitoring signal receiving unit 2122. The first monitoring signal transmitting unit 2121 and the first monitoring signal receiving unit 2122 are split structures and are arranged on opposite sides of the output shaft 223. When the output shaft 223 rotates until the first monitoring signal transmitting unit 2121, the first signal transmission hole 2232 and the first monitoring signal receiving unit 2122 are aligned, the first monitoring signal transmitting unit 2121 and the first signal receiving unit 2122 are located at the axial ends of the first signal transmission hole 2232. In this way, the monitoring signal emitted by the first monitoring signal transmitting unit 2121 can be transmitted to the first signal receiving unit 2122 along the first signal transmission hole 2232.

[0070] Alternatively, if Figure 7 As shown, the first sensor 212 also includes a first monitoring signal transmitting unit and a first monitoring signal receiving unit, but the two are an integrated structure. The first sensor 212 is spaced apart from one end face of the output shaft 223, and the end face of the output shaft 223 facing the first sensor 212 is a rough surface, and the first signal transmission hole 2232 is a blind hole arranged on the end face of the output shaft 223 facing the first sensor 212. The axis of the first signal transmission hole 2232 is parallel to the axis of the output shaft 223, and the bottom surface of the second signal transmission hole 2233 is a smooth surface. When the output shaft 223 rotates until the first signal transmission hole 2232 is aligned with the first sensor 212, the monitoring signal emitted by the first sensor 212 is transmitted along the first signal transmission hole 2232 to the bottom of the first signal transmission hole 2232, and then a mirror reflection occurs at the bottom of the first signal transmission hole 2232, and the reflected monitoring signal is then transmitted to the first sensor 212. When the first sensor 212 is offset from the first signal transmission hole 2232, the monitoring signal emitted by the first sensor 212 is diffusely reflected when it is transmitted to the end face of the output shaft 223, and the reflected monitoring signal cannot be transmitted back to the first sensor 212, so that the first sensor 212 cannot receive the monitoring signal. It should be noted that the first sensor 212 is spaced apart from an end face of the output shaft 223, which means that the first sensor 212 and the output shaft 223 are arranged along the axial direction of the output shaft 223, and the distance from the first sensor 212 to the end face of the output shaft 223 facing the first sensor 212 is greater than zero.

[0071] In the aforementioned structure of the second component 100, the size of the volume of the medium storage space 112 is related to the position of the execution unit 120 relative to the medium storage part 110. Therefore, a target part is defined on the execution unit 120, and a first predetermined position is defined on the medium storage part 110, and when the target part reaches the first predetermined position, the volume of the medium storage space 112 is made the first predetermined volume. Therefore, when the electrical signal acquisition part 210 obtains the third position signal, it indicates that the target part has reached the first predetermined position. In an optional embodiment, the target part is the push part 121. For ease of understanding, the push part 121 is used as an example of the target part in the following text, but those skilled in the art can modify the following description to adapt to the situation where the target part is not the push part 121.

[0072] Optionally, continue to refer to Figure 6 and Figure 7 , and combined with Figure 8 The electrical signal acquisition unit 210 further includes a second sensor 213, and the second sensor 213 is used to obtain the third position signal. Specifically, when the second sensor 213 receives the monitoring signal emitted by itself, the second sensor 213 obtains the third position signal. In an optional embodiment, the second sensor 213 is a photoelectric sensor, and the corresponding monitoring signal is an optical signal.

[0073] Optionally, the output shaft 223 is provided with a second signal transmission hole 2233 different from the first signal transmission hole 2232, and the second sensor 213 is arranged corresponding to the second signal transmission hole 2233. During the rotation of the output shaft 223, the second signal transmission hole 2233 is aligned with or staggered from the second sensor 213. When the second signal transmission hole 2233 is aligned with the second sensor 213, the monitoring signal emitted by the second sensor 213 can be received by the second sensor 213 after passing through the second signal transmission hole 2233. When the second signal transmission hole 2233 is staggered from the second sensor 213, the second sensor 213 cannot receive the monitoring signal emitted by itself.

[0074] In an optional embodiment, if Figure 6As shown, the second signal transmission hole 2233 passes through the output shaft 223, and the axis of the second signal transmission hole 2233 is not in the same plane as the axis of the output shaft 223, and preferably the two are perpendicular. The second sensor 213 includes a second monitoring signal transmitting part 2131 and a second monitoring signal receiving part 2132, and the second monitoring signal transmitting part 2131 and the second monitoring signal receiving part 2132 are split structures and are arranged on opposite sides of the output shaft 223. When the output shaft 223 rotates until the second monitoring signal transmitting part 2131, the second signal transmission hole 2233, and the second signal receiving part 2132 are aligned, the second monitoring signal transmitting part 2131 and the second signal receiving part 2132 are located at the axial ends of the second signal transmission hole 2233. In this way, the monitoring signal emitted by the second monitoring signal transmitting part 2131 can be transmitted to the second signal receiving part 2132 along the second signal transmission hole 2233.

[0075] In an alternative embodiment, if Figure 7 As shown, the second sensor 213 also includes a second monitoring signal transmitting unit and a second monitoring signal receiving unit, but the two are an integrated structure. The second sensor 213 is spaced apart from one end face of the output shaft 223, and the end face of the output shaft 223 facing the second sensor 213 is a rough surface, the second signal transmission hole 2233 is a blind hole arranged on the end face of the output shaft 223 facing the second sensor 212, the axis of the second signal transmission hole 2233 is parallel to the axis of the output shaft 223, and the bottom surface of the second signal transmission hole 2233 is a smooth surface. When the output shaft 223 rotates until the second signal transmission hole 2233 is aligned with the second sensor 213, the monitoring signal emitted by the second sensor 213 is transmitted along the second signal transmission hole 2233 to the bottom of the second signal transmission hole 2233, and mirror reflection occurs, and the reflected monitoring signal is transmitted back to the second sensor 213. When the second sensor 213 is staggered from the second signal transmission hole 2233, the monitoring signal emitted by the second sensor 213 is diffusely reflected when being transmitted to the end face of the output shaft 223, and the reflected monitoring signal cannot be transmitted back to the second sensor 213. It can be understood that the first sensor 212 is spaced apart from an end face of the output shaft 223, which means that the first sensor 212 and the output shaft 223 are arranged along the axial direction of the output shaft 223, and the distance from the first sensor 212 to the end face of the output shaft 223 facing the first sensor 212 is greater than zero.

[0076] In another alternative embodiment, Figure 8As shown, the medium storage unit 110 is configured to allow the monitoring signal emitted by the second sensor 213 to pass through at the first predetermined position, and the pushing unit 121 is configured to be able to reflect the monitoring signal emitted by the second sensor 213. In addition, the first housing 130 is provided with a passing portion (not shown in the figure) corresponding to the first predetermined position to allow the monitoring signal emitted by the second sensor 213 to pass through. The second sensor 213 includes a second monitoring signal emitting portion and a second monitoring signal receiving portion, and the two are of an integrated structure. The second sensor 213 is disposed on one side of the medium storage unit 110 and is arranged corresponding to the first predetermined position. In this way, when the pushing unit 121 does not reach the first predetermined position, the monitoring signal emitted by the second sensor 213 passes through the first housing 130 and the medium storage unit 110 and continues to be transmitted in a direction away from the second sensor 213, and when the pushing unit 121 reaches the first predetermined position, the monitoring signal emitted by the second sensor 213 is reflected by the pushing unit 121 located at the first predetermined position, and the reflected monitoring signal is finally transmitted to the second sensor 213.

[0077] Specifically, in the case where the second sensor 213 is the photoelectric sensor, the medium storage unit 110 is transparent at the first predetermined position, and the first housing 130 is transparent or provided with a light-transmitting hole corresponding to the first predetermined position. The pushing unit 121 is opaque.

[0078] In a preferred embodiment, a second predetermined position is further defined on the medium storage unit 210. When the target part, such as the pushing unit 121, reaches the second predetermined position, the volume of the medium storage space 112 is the second predetermined volume, the second predetermined volume is smaller than the first predetermined volume, and the difference between the first predetermined volume and the second predetermined volume is the second preset value.

[0079] It can be understood that when the pushing unit 121 is located at the first predetermined position, the control unit 220 stops operating so that the volume of the medium storage space 112 remains unchanged, thereby keeping the balloon 300 in a pressure-relieved state, or the driving unit 220 operates to drive the execution unit 120 to move in a direction that reduces the volume of the medium storage space 112, so that the balloon 300 gradually fills.

[0080] In practice, when the balloon 300 is inflated to its inflation pressure being the first preset value, it is desired that the driving unit 220 no longer drives the actuating unit 120 to move in the direction of reducing the volume of the medium storage space 112. The reason is that in the case where the first predetermined volume is equal to the predetermined volume, when the balloon 300 is inflated to its inflation pressure being the first preset value, the medium storage space 112 is reduced to zero, and the actuating unit 120 cannot continue to move in the direction of reducing the medium storage space 112. At this time, if the driving unit 220 continues to drive the actuating unit 120 to move in the direction of reducing the volume of the medium storage hole 112, the driving unit 220 is likely to malfunction due to the blocked movement of the actuating unit 120. In the case where the first predetermined volume is greater than the second preset value, when the balloon 300 is inflated to its inflation pressure being the first preset value, there is still medium stored in the medium storage space 112, and the medium storage space 112 can be further reduced. At this time, if the driving unit 220 continues to drive the actuating unit 120 to move in the direction of reducing the medium storage space 112, more medium will be pushed into the balloon 300, resulting in the inflation pressure of the balloon 300 being greater than the first preset value, which may cause harm to the patient.

[0081] In view of this, it is also preferably to define a second predetermined position on the medium storage part 210 such that when the target part, for example, the pushing part 121 reaches the second predetermined position, the medium storage space 112 has a second predetermined volume, the second predetermined volume is smaller than the first predetermined volume, and the difference between the first predetermined volume and the second predetermined volume is the second preset value. Thus, the first target signal further includes a fourth position signal indicating that the target part reaches the second predetermined position.

[0082] The acquisition method of the fourth position signal can refer to the acquisition method of the third position signal. That is, the electrical signal acquisition unit 210 further includes a third sensor (not labeled in the figure). When the third sensor acquires the monitoring signal emitted by itself, the third sensor acquires the third position signal. The third sensor can be a photoelectric sensor, and the corresponding monitoring signal is an optical signal.

[0083] Optionally, a third signal transmission hole (not shown in the figure) different from the first signal transmission hole 2232 and also different from the second signal transmission hole 2233 is provided on the output shaft 223, and the third sensor is arranged corresponding to the third signal transmission hole. During the rotation of the output shaft 223, the third signal transmission hole is aligned or misaligned with the third sensor. When the third signal transmission hole is aligned with the third sensor, the monitoring signal emitted by the third sensor can be received by the third sensor after passing through the third signal transmission hole. When the third signal transmission hole is misaligned with the third sensor, the third sensor cannot receive the monitoring signal emitted by itself.

[0084] For the specific configuration of the third signal transmission hole, reference can be made to the first signal transmission hole 2232 or the second signal transmission hole 2233. For the corresponding configuration of the third sensor, reference can be made to the configuration of the first sensor 212 or the second sensor 213, which will not be elaborated here.

[0085] It should be noted that when at least two of the first signal transmission hole 2232, the second signal transmission hole 2233, and the third signal transmission hole penetrating through the output shaft 223 are provided, the axes of any two signal transmission holes should be skew to avoid signal crosstalk.

[0086] Alternatively, the medium storage portion 110 is configured to allow the monitoring signal emitted by the second sensor 213 to pass through at the second predetermined position, and the pushing portion 121 is configured to be able to reflect the monitoring signal emitted by the second sensor 213. The first housing 130 is provided with a through portion (not shown in the figure) corresponding to the second predetermined position to allow the monitoring signal emitted by the third sensor to pass through. The third sensor includes a third monitoring signal emitting portion and a third monitoring signal receiving portion, and the two are of an integrated structure. The third sensor is arranged on one side of the medium storage portion 110 and is arranged corresponding to the second predetermined position. In this way, when the pushing portion 121 does not reach the second predetermined position, the monitoring signal emitted by the third sensor passes through the first housing 130 and the medium storage portion 110 and then continuously transmits in a direction away from the third sensor. When the pushing portion 121 reaches the second predetermined position, the monitoring signal emitted by the third sensor is reflected by the pushing portion 121 located at the second predetermined position, and the reflected monitoring signal is finally transmitted to the third sensor.

[0087] Specifically, in the case where the third sensor is an optical sensor, the medium storage portion 110 is transparent at the second predetermined position, and the first housing 130 is transparent or provided with a light-transmitting hole corresponding to the second predetermined position. The pushing portion 121 is opaque.

[0088] It should be noted that in the embodiments of the present utility model, any suitable method can be adopted to supply power to the first sensor 212, the second sensor 213, the third sensor, the control unit 230, and the drive unit 220. Optional methods include, for example, using a storage battery as a power source to supply power to these components, or directly connecting these components to the mains power system to obtain electrical energy, etc.

[0089] Furthermore, the embodiments of the present utility model further provide a medical system, including the aforementioned balloon catheter 20 and the aforementioned medical balloon perfusion system 10.

[0090] Although the present utility model is disclosed as above, it is not limited thereto. Those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
