[0045] The specific implementation of the present invention will be described in more detail below in conjunction with the schematic diagram. The advantages and features of the present invention will become clearer based on the following description. It should be noted that the drawings are all in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.

[0046] The term "vacuum" herein refers to a state of gas in a certain space with a pressure lower than one atmosphere, and also includes a quasi-vacuum state, i.e., a gas state expected to be lower than one atmosphere. The term "fillable space" refers to a space that can be connected to the outside and can be filled or exhausted with gas or liquid.

[0047] Embodiment 1

[0048] A medical device, such as a balloon used in aortic valve surgery. After the balloon is expanded, it fits with the aortic valve. In order to prevent the balloon from sliding after expansion, the applicant has developed the balloon in this embodiment, which adopts a double-layer or multi-layer design. Therefore, the balloon includes at least one sealed space.

[0049] Figure 1 Schematic diagram of a balloon in an embodiment of the present invention. Figure 1 As shown, the balloon 200 has a sealed space 230. For example, the balloon 200 includes a first balloon 210 and a second balloon 220, and the sealed space 230 exists between the first balloon 210 and the second balloon 220. The amount of residual gas in the sealed space 230 needs to meet specific requirements. The space inside the first balloon 210 is a fillable space 240. The first balloon 210 is filled by filling the fillable space 240 to expand the balloon 200. The second balloon 220 is sheathed outside the first balloon 210. The second balloon 220 is a straight balloon. After the first balloon 210 is filled, it forms a "dog bone shape". The first balloon 210 expands the second balloon 220, so that the second balloon 220 is in a "peanut shape". The "peanut shape" shape is conducive to the fit of the balloon 200 to the aortic valve. Therefore, the balloon 200 can effectively prevent the problem of sliding when it expands, and meet its use in aortic valve surgery to reduce surgical risks and improve surgical quality.

[0050] There is a sealed space 230 between the first balloon 210 and the second balloon 220, and the sealed space 230 is a vacuum space. Therefore, the amount of residual gas in the sealed space 230 needs to meet the vacuum requirement in order to reduce the risk of gas embolism after the balloon 200 ruptures in the body. Therefore, during the production process of the balloon 200, each batch of balloon 200 products needs to be sampled to measure the amount of residual gas in the balloon 200, that is, the amount of gas in the sealed space 230.

[0051] Figure 2 FIG. 1 is a schematic diagram of a medical device measurement system in an embodiment of the present invention. Figure 1 and Figure 2As shown, the medical device is a balloon 200, and the balloon 200 includes at least one sealed space 230 and a fillable space 240. The medical device measurement system 100 is used to measure the amount of gas in the sealed space 230. The medical device measurement system 100 includes: an isolation module, a filling and suction module 150 and a gas measurement unit 110. Among them, the isolation module includes a first container 170, a second container 130 and a balloon 200, the first container 170 is connected to the second container 130, and the balloon 200 is placed inside the second container 130 and isolated from the air outside the second container 130. The filling and suction module 150 is connected to the isolation module, and is used to exhaust the gas in the fillable space 240 in the balloon 200 and to perfuse the first liquid into the fillable space 240 to rupture the balloon 200. The gas measurement unit 110 is connected to the isolation module and is used to measure the amount of gas in the sealed space 230 after the balloon 200 is ruptured.

[0052] Optionally, the first container 170 in the isolation module is used to accommodate the second liquid, and the second container 130 is arranged inside the first container 170. Further, the first container 170 and the second container 130 are both open containers, and the opening of the first container 170 is opposite to the opening of the second container 130. Among them, the opening of the first container 170 is placed upward, and the opening of the second container 130 is placed downward, and is placed upside down inside the first container 170, so that the interior of the first container 170 is connected to the interior of the second container 130. The interior of the first container 170 accommodates the second liquid. The second container 130 is immersed in the second liquid, so that the second container 130 is filled with the second liquid, thereby isolating the balloon 200 from the air. It should be known that the interior of the second container 130 is filled with the second liquid, the purpose of which is to form a closed liquid environment inside the second container 130. In this way, when the balloon 200 is placed inside the second container 130, the surrounding of the balloon 200 is a closed liquid environment.

[0053] In this embodiment, the first liquid and the second liquid can be the same liquid. Preferably, the first liquid and the second liquid are both water. Of course, the first liquid and the second liquid can also be oil or ethanol, which is not limited here. It should be known that the first liquid and the second liquid are water, which has better economy and safety.

[0054] It should be known that the first container 170 and the second container 130 can be a square trough, a circular trough or a water trough of other shapes. The shapes of the first container 170 and the second container 130 can be the same or different. For example, the first container 170 and the second container 130 can both be circular troughs, or the first container 170 and the second container 130 can both be square troughs, or the first container 170 and the second container 130 can both be square troughs, or the first container 170 is a square trough and the second container 130 is a circular trough, or the first container 170 is a circular trough and the second container 130 is a square trough. Preferably, the first container 170 and the second container 130 in this embodiment are both circular troughs. It should be understood that the function of the first container 170 and the second container 130 is to form a closed liquid environment inside the second container 130. Those skilled in the art can change the shape and size of the first container 170 and the second container 130 according to actual needs without violating the concept of the present invention.

[0055] Figure 3 FIG. 2 is another schematic diagram of a medical device measurement system in an embodiment of the present invention. Figure 3 As shown, the first container 170 and the second container 130 are arranged side by side, the balloon 200 is placed in the second container 130, and the bottoms of the first container 170 and the second container 130 are connected by a pipe. In this way, the interior of the second container 130 is filled with the second liquid. In this embodiment, the size of the first container 170 can be the same as the size of the second container 130, and the size of the first container 170 can even be smaller than the size of the second container 130. In this way, the space occupied by the medical device measurement system 100 can be reduced.

[0056] Continue to refer to Figure 2 In a specific implementation, the inflation and suction module 150 is used to connect with the first balloon 210 in the balloon 200, and is used to suck the gas inside the first balloon 210 and to infuse the first liquid into the first balloon 210 until the first balloon 210 and the second balloon 220 are broken. It should be known that since the surrounding of the balloon 200 is a closed liquid environment, when the first balloon 210 and the second balloon 220 are broken, the first balloon 210 and the second balloon 220 will break from the top of the balloon 200 along the axial direction to the bottom of the balloon 200, so that the sealed space 230 between the first balloon 210 and the second balloon 220 is exposed to the closed liquid environment. If there is residual gas in the sealed space 230, the residual gas will float upward due to the influence of buoyancy and gather in the upper area inside the second container 130.

[0057] Continue to refer to Figure 2In a specific implementation, the gas measurement unit 110 is connected to the second container 130. Specifically, the gas measurement unit 110 is located above the second container 130. The medical device measurement system 100 further includes a gas conduit 140, through which the gas measurement unit 110 is connected to the upper portion of the second container 130. Since the interior of the first container 170 is connected to the interior of the second container 130, the residual gas gathered in the upper region of the interior of the second container 130 will flow into the gas measurement unit 110 under the action of atmospheric pressure, and the gas measurement unit 110 can measure the residual gas amount.

[0058] Optionally, the gas measurement unit 110 may be a gas volume display, which has high measurement accuracy, can intuitively display the on-site gas concentration, and is easy to operate. In this embodiment, the gas volume display has a range of 0-5 mL and a measurement sensitivity of 0.1 mL.

[0059] Optionally, the gas measurement unit 110 may also adopt a gas flow meter to obtain the volume of the gas by detecting the gas flow rate and the time for the gas to flow through the gas flow meter.

[0060] Furthermore, the medical device measurement system 100 further includes a stop valve 120 , which is disposed on the gas conduit 140 , and the second container 130 is controlled to be in communication with the gas measurement unit 110 through the stop valve 120 .

[0061] Specifically, the stop valve 120 has a first end and a second end, wherein the first end is connected to the bottom end 131 of the second container 130, and the second end is connected to the gas measuring unit 110. The stop valve 120 is used to control the communication state between the gas measuring unit 110 and the interior of the second container 130. When the stop valve 120 is closed, the gas measuring unit 110 is not connected to the interior of the second container 130, and the second container 130 maintains a closed liquid environment. The gas inside the second container 130 floats upward and gathers in the upper area inside the second container 130. When the stop valve 120 is opened, the gas gathered in the upper area inside the second container 130 flows into the gas measuring unit 110 through the stop valve 120 under the action of atmospheric pressure.

[0062] Continue to refer to Figure 2 The charging and suction module 150 includes a suction unit 155 and a charging unit 154 .

[0063] The suction unit 155 is used to exhaust the gas in the inflatable space 240. Specifically, the suction unit 155 exhausts the gas in the inflatable space 240 to the outside of the first balloon 210.

[0064] The inflation unit 154 injects the first liquid into the inflatable space 240 until the balloon 200 ruptures, so that the sealed space 230 is exposed to a closed liquid environment.

[0065] Furthermore, the inflation and suction module 150 further includes a switching valve 156, through which the balloon 200 is controlled to communicate with the suction unit 155 or the inflation unit 154. In this embodiment, the switching valve 156 is a three-way valve.

[0066] Furthermore, the medical device measurement system 100 also includes a first pipeline 151, a second pipeline 152 and a third pipeline 153, the switching valve 156 has a first input end 156a, a second input end 156b and an output end 156c, the suction unit 155 is connected to the first input end 156a through the first pipeline 151, the charging unit 154 is connected to the second input end 156b through the second pipeline 152, and the first balloon 210 is connected to the output end 156c through the third pipeline 153.

[0067] In detail, the charging unit 154, the suction unit 155 and the switching valve 156 are all located outside the first container 170. The third pipeline 153 is connected to the first balloon 210, and one end of the third pipeline 153 is located inside the second container 130 for connection with the first balloon 210. The other end of the third pipeline 153 passes through the first container 170 and is connected to the output end 156c of the switching valve 156 outside the first container 170. The position where the third pipeline 153 passes through the first container 170 can be located on the side or bottom of the first container 170. It can be understood that the position where the third pipeline 153 passes through the first container 170 can be adjusted so that the position of the switching valve 156 can be adjusted as needed. More preferably, a sealing ring 180 is provided at the position where the third pipeline 153 passes through the first container 170. In this way, the sealing ring 180 can prevent the air outside the first container 170 from entering the interior of the second container 130, which is conducive to improving the sealing performance of the second container 130. The second container 130 has better sealing performance, which is beneficial to improving the measurement accuracy of the medical device measurement system 100.

[0068] The suction unit 155 is connected to the first balloon 210 through the first pipeline 151, the first input end 156a of the switching valve 156, and the third pipeline 153. When the switching valve 156 controls the first input end 156a to be connected to the output end 156c, the suction unit 155 is connected to the third pipeline 153 and the interior of the first balloon 210, and the suction unit 155 generates a negative pressure environment to evacuate the gas inside the first balloon 210. It should be understood that before the first liquid is perfused into the interior of the first balloon 210, the gas inside the first balloon 210 is sucked cleanly in order to prevent the gas inside the first balloon 210 from escaping into the interior of the second container 130 when the first balloon 210 and the second balloon 220 are ruptured, thereby affecting the measurement result of the residual gas in the balloon 200.

[0069] In a specific implementation, the suction unit 155 may be an air pump, which can continuously form a vacuum or negative pressure, is widely used in the market, has a relatively low price, and is conducive to reducing the manufacturing cost of the medical device measurement system 100 .

[0070] The charging unit 154 is connected to the first balloon 210 through the second pipeline 152, the second input end 156b of the switching valve 156 and the third pipeline 153. When the switching valve 156 controls the second input end 156b to be connected with the output end 156c, the charging unit 154 is connected with the third pipeline 153 and the interior of the first balloon 210. The charging unit 154 generates a certain flow of the first liquid and injects the first liquid into the interior of the first balloon 210, so that the pressure inside the first balloon 210 gradually increases to burst the first balloon 210 and the second balloon 220.

[0071] In a specific implementation, the charging unit 154 may be an infusion pump. The infusion pump can generate a certain flow of the first liquid, which is used to infuse the first liquid into the first balloon 210, so as to increase the pressure inside the first balloon 210, so as to rupture the first balloon 210 and the second balloon 220. In addition, the infusion pressure of the infusion pump can be adjusted and set as needed, and can also be monitored in real time, so as to facilitate the use of the medical device measurement system 100.

[0072] Optionally, the medical device measurement system 100 further includes a control unit, configured to control the inflation / absorption module 150 to exhaust the gas inside the inflatable space 240 and to infuse the first liquid into the inflatable space 240 .

[0073] It should be known that the medical device measurement system 100 can be manually controlled by the user to control the charging unit 154, the suction unit 155, the switching valve 156 and the stop valve 120 to achieve the purpose of measuring the residual gas volume of the balloon 200. However, the charging unit 154, the suction unit 155, the switching valve 156 and the stop valve 120 are automatically controlled by the control unit, which is conducive to improving the convenience of using the medical device measurement system 100.

[0074] Furthermore, the control unit has a control panel 190 , and the control panel 190 has a display screen 191 , and the display screen 191 displays the gas amount.

[0075] In a specific implementation, the control panel 190 has a display screen 191, a power switch A, a gas display switch B, a charging mode switch C, and a suction mode switch D. The power switch A is used to control the medical device measurement system 100 to be powered. The gas display switch B is used to control the display screen 191 to display the measurement value of the gas measurement unit 110. The charging mode switch C is used to control the medical device measurement system 100 to perfuse the first liquid into the interior of the first balloon 210. The suction mode switch D is used to control the medical device measurement system 100 to suction the gas inside the first balloon 210.

[0076] Optionally, the medical device measurement system 100 further includes a housing 160. The first container 170, the second container 130, the charging and suction module 150, and the gas measurement unit 110 are all located inside the housing 160, and the control panel 190 is embedded in the housing 160. In this way, the medical device measurement system 100 forms a whole, which is convenient for users to carry.

[0077] Correspondingly, the present invention also provides a method for measuring residual gas in a balloon 200, using the medical device measurement system 100 in this example.

[0078] Figure 4 FIG. 4 is a flow chart of the method for measuring the residual gas in the balloon in this embodiment. Figures 1 to 4 As shown, the method for measuring the residual gas in the balloon 200 includes:

[0079] Step S1: the inflation / suction module 150 extracts gas from the interior of the first balloon 210;

[0080] In a specific implementation, the suction unit 155 is controlled to communicate with the third pipeline 153 and the interior of the first balloon 210 through the switching valve 156 , and the suction unit 155 is started to suck the gas inside the first balloon 210 .

[0081] It should be noted that before executing step S1, the process of placing the balloon 200 is also included, which is as follows:

[0082] First, the first balloon 210 is connected to one end of the third pipeline 153;

[0083] Next, the second container 130 is placed upside down in the first container 170 and the first balloon 210 is covered so that the first balloon 210 is placed inside the second container 130;

[0084] Then, the second liquid is injected into the first container 170 until the second container 130 is submerged by the second liquid and the interior of the second container is filled with the second liquid.

[0085] It should be known that when the second liquid is injected into the first container 170, the second container 130 may float. In a specific implementation of this embodiment, the gas conduit 140 is connected to the upper part of the second container 130, and the stop valve 120 is arranged on the gas conduit 140. When the second liquid is injected into the first container 170, when the stop valve 120 is opened, the air inside the second container 130 can be discharged from the gas conduit 140, so as to avoid the problem of floating of the second container 130 due to the inability to discharge the air inside the second container 130 during the process of injecting the second liquid into the first container 170. In addition, since the interior of the first container 170 is connected to the interior of the second container 130, when the second liquid submerges the second container 130, the air inside the second container 130 will be completely discharged, so that the interior of the second container 130 is filled with the second liquid. At this time, the stop valve 120 is closed, and a closed liquid environment is formed inside the second container 130. Afterwards, the gas measurement unit 110 is connected to the gas conduit 140, and the process of placing the balloon 200 is completed.

[0086] Step S2: the inflation / suction module 150 injects the first liquid into the first balloon 210 until the first balloon 210 and the second balloon 220 rupture;

[0087] In specific implementation, after a set time, the charging unit 154 is controlled by the switching valve 156 to be connected with the third pipeline 153 and the interior of the first balloon 210 through the second pipeline 152. Then, the suction unit 155 is closed, and the charging unit 154 is started to infuse the first liquid into the interior of the first balloon 210 until the first balloon 210 and the second balloon 220 rupture, so that the residual gas between the first balloon 210 and the second balloon 220 enters the interior of the second container 130. Then, the charging unit 154 is closed.

[0088] The set time is, for example, 20-25 seconds, which can be adjusted as needed during specific implementation. During the set time, the suction unit 155 sucks the gas inside the first balloon 210. The range of the set time (also understood as the suction time) is determined according to the product characteristics of the balloon 200. For example, a larger balloon 200 requires a longer suction time to ensure that the air inside the first balloon 210 is emptied. Therefore, different balloon 200 products have different corresponding suction times.

[0089] Step S3 : the gas measuring unit 110 obtains the residual gas volume of the balloon 200 according to the gas volume inside the second container 130 .

[0090] Embodiment 2

[0091] The device for measuring residual gas in the balloon provided in this embodiment is not described again in terms of the same parts as those in the first embodiment, and only the differences are described below.

[0092] Figure 5 FIG. 1 is a schematic diagram of a medical device measurement system in an embodiment of the present invention. Figure 5 As shown, the difference between this embodiment and the first embodiment is that the switching valve 156 in the medical device measurement system 100 includes a first one-way valve 156d and a second one-way valve 156e, the first one-way valve 156d is arranged on the first pipeline 151, and the second one-way valve 156e is arranged on the second pipeline 152.

[0093] The suction unit 155 is connected to the first balloon 210 through the first pipeline 151, the first one-way valve 156d and the third pipeline 153. When the first one-way valve 156d is opened, the suction unit 155 is connected to the third pipeline 153 and the interior of the first balloon 210.

[0094] The charging unit 154 is connected to the first balloon 210 through the second pipeline 152, the second one-way valve 156e and the third pipeline 153. When the second one-way valve 156e is opened, the charging unit 154 is connected to the third pipeline 153 and the interior of the first balloon 210.

[0095] It should be known that in the first embodiment, the switching valve 156 is a three-way valve. During the switching operation of the three-way valve, there is a problem of input terminal collusion, which may cause the charging unit 154 to collude with the suction unit 155, resulting in the second liquid being poured into the suction unit 155, which is undesirable. In the present embodiment, the first one-way valve 156d and the second one-way valve 156e are used to control the first balloon 210 to communicate with the suction unit 155 or the charging unit 154. After the first one-way valve 156d is closed, the second one-way valve 156e can be opened after a period of time. In this way, when the switching operation is performed, the charging unit 154 and the suction unit 155 can be prevented from colluding.

[0096] In summary, in the medical device measurement system provided in the embodiment of the present invention, the medical device includes at least one sealed space and a fillable space, the measurement system is used to measure the amount of gas in the sealed space, and the measurement system includes an isolation module, a filling module and a gas measurement unit. The isolation module includes a first container, a second container and the medical device, the first container is connected to the second container, and the medical device is placed inside the second container and isolated from the air outside the second container. The filling module is connected to the isolation module, and is used to exhaust the gas in the fillable space and to fill the fillable space with a first liquid to rupture the medical device. The gas measurement unit is connected to the isolation module and is used to measure the amount of gas in the sealed space after the medical device ruptures. In the present invention, the medical device is placed inside the second container and is isolated from the air outside the second container, so that the medical device is located in a closed liquid environment. The filling module is connected to the isolation module, and is used to exhaust the gas in the fillable space and to fill the fillable space with a first liquid to rupture the medical device, so that the sealed space is exposed to the closed liquid environment. If there is gas in the sealed space, the gas will gather in the upper area inside the second container. The gas measuring unit is connected to the isolation module and is used to measure the amount of gas in the sealed space after the medical device is ruptured.
