Description

Technical Field

[0001] The utility model relates to the field of refrigeration medical equipment, and specifically comprises an anti-ice blockage heat exchange system device and a heat exchanger. Background Art

[0002] Cryoablation equipment is a device that uses extremely cold working fluid to freeze and destroy abnormal cells or diseased tissues. It can be used to treat various cancers and arrhythmias. In cryoablation, the cryoablation equipment needs to be connected to an ablation device (disposable consumables), such as an ablation needle, balloon catheter, etc., and extremely cold working fluids such as liquid nitrogen, argon, nitrous oxide or carbon dioxide are introduced into the ablation device to generate low temperatures at the treatment site, thereby freezing the diseased tissue.

[0003] Generally speaking, there are two main methods for obtaining cryogenic fluids: one is to obtain liquid fluids through the Joule-Thomson throttling principle, and the other is to obtain liquid fluids through heat exchange through a heat exchanger. The former is not safe enough due to the high working pressure, while the latter is relatively more convenient and efficient. Therefore, most domestic ablation equipment uses the latter to obtain liquid fluids.

[0004] Taking nitrogen as the working fluid for a specific explanation, nitrogen at a certain pressure is introduced into a heat exchanger placed in a liquid nitrogen tank. The nitrogen exchanges heat with the liquid nitrogen in the liquid nitrogen tank and undergoes phase change to liquefy into liquid nitrogen. The liquid nitrogen is then continuously transported to the ablation device to support cryotherapy.

[0005] However, heat exchange cryoablation equipment has a drawback, namely: when the ablation device is unplugged after the treatment, the liquid outlet pipe of the equipment heat exchanger will be connected to the atmosphere. At this time, the moisture in the atmosphere will continue to diffuse into the heat exchanger in the liquid nitrogen tank. Because the heat exchanger is surrounded by a cold environment, the moisture in the air freezes when it is cold, causing ice crystals to form in the liquid outlet pipe of the equipment and form ice blockage, affecting the next cryotherapy.

[0006] At present, the solution to the above problem is to add a plug as a spare part. When the operation is completed and the ablation device is removed, the doctor needs to install the plug at the interface between the device and the ablation device to prevent moisture in the air from entering the liquid outlet pipe of the heat exchanger. When the next operation is performed, the plug will be removed and the ablation device will be connected to the interface of the heat exchanger.

[0007] Obviously, this method cannot completely solve the ice blockage problem, because the doctor may forget to install the plug after the operation due to the long operation, and installing the plug will also increase the doctor's labor intensity. The utility model aims to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0038] Embodiment 1

[0039] like Figure 3 As shown, an anti-icing and blocking heat exchange system device includes a connecting seat 11 and a heat exchange mechanism 12 and an anti-icing and blocking pipeline 13 arranged on the connecting seat 11.

[0040] like Figure 1-3 As shown, in one embodiment, the above-mentioned anti-icing heat exchange system device can be assembled on a refrigeration container 101, for example, assembled on a dewar tank, to form a complete heat exchange system (i.e., a heat exchanger), so as to achieve the purpose of using the liquid medium (i.e., cooling medium) in the dewar tank to cool and liquefy the gas source (i.e., the working medium) to form a liquid medium. The types of the cooling medium and the working medium can be the same or different, preferably the same, for example, both are N2.

[0041] The heat exchange system formed by the anti-icing heat exchange system device can cool and liquefy pure gaseous media (i.e., working media) to form liquid for medical use, avoiding the high cost and inconvenience of directly liquefying high-purity gas sources for medical use, which is beneficial to medical applications. This principle is a mature technology and has been applied in the prior art.

[0042] Different from the existing heat exchange system, this embodiment also has an anti-ice blockage function, that is, after the medical device is removed from the system, gas will be generated in the system pipeline to prevent air from entering the pipeline, thereby avoiding the subsequent use when low-boiling point substances such as moisture in the air are cooled by the liquid medium and liquefied or solidified to form ice crystals to block the pipeline.

[0043] In this embodiment, the heat exchange mechanism 12 includes a heat exchange part 121 and an inlet pipe 122 and an outlet pipe 123 connected to the heat exchange part 121. At least one of the inlet pipe 122 and the outlet pipe 123 is fastened or movably connected to the connection seat 11. When fastened, the position of the heat exchange part 121 relative to the connection seat 11 is fixed, and when movably connected, the relative position of the two can be adjusted. Among them, the heat exchange part 121 can be various heat exchange devices with a large contact area, such as a spiral heat exchange tube, so that the working medium flowing in the heat exchange mechanism 12 can have a large thermal contact area with the cooling medium in the refrigeration container, thereby meeting the purpose of cooling and liquefying the working medium using the cooling medium.

[0044] In this embodiment, the structure and relative position relationship of the heat exchange mechanism 12 and the connecting seat 11 can preferably be configured so that the heat exchange part 121 is located in the middle position or the lower middle position of the refrigeration cavity 102 of the refrigeration container 101, so that the heat exchange part 121 is generally located in the middle of the refrigeration medium or close to the middle protection position, thereby ensuring that the heat exchange cooling effect meets the standards.

[0045] like Figure 3 As shown, the anti-icing and blocking pipeline 13 has an anti-icing and blocking branch pipe 131 and a one-way valve 132 installed on the anti-icing and blocking branch pipe 131. The two ends of the anti-icing and blocking branch pipe 131 are respectively formed as a first branch pipe opening 133 and a second branch pipe opening 134. The first branch pipe opening 133 is connected to the outlet pipe 123, and the second branch pipe opening 134 is vacant for connecting to the refrigeration chamber 102.

[0046] In this embodiment, the connection seat 11 is formed as a cover-shaped component that can be sealably assembled to the container opening 103 of the refrigeration container 101, so that a sealed space is formed in the refrigeration chamber 102. The anti-icing branch pipe 131 is arranged to penetrate the connection seat 11 so that the second branch pipe opening 134 is connected to the refrigeration chamber 102.

[0047] A conduit joint 124 is formed at the outer end of the outlet pipe 123 , and the first branch pipe opening 133 is arranged close to the conduit joint 124 , so that the anti-icing and blocking jet is arranged close to the conduit joint 124 .

[0048] Of course, in other embodiments, the connection base 11 may not be set as a cover-shaped component of the refrigeration container 101, but it may be assembled and positioned at a certain position in the refrigeration cavity 102, such as at the bottle mouth, and another cover that can seal the container mouth 103 is used to seal the refrigeration container 101. In this case, the inlet pipe 122 and the outlet pipe 123 are set through the cover.

[0049] like Figure 3 As shown, in this embodiment, the connection seat 11 is further provided with a pressure relief valve 111 and a medium replenishing port 112, the pressure relief valve 111 is used to relieve pressure when the pressure in the refrigeration chamber 102 is too high, and the medium replenishing port 112 is used to replenish the cooling medium into the refrigeration chamber 102. The pressure relief valve 111 and the medium replenishing port 112 are mature in the prior art, and their structures and settings can be set as needed.

[0050] The use process and principle of the anti-icing heat exchange system device of this embodiment are described as follows:

[0051] 1. Assemble the anti-icing heat exchange system device of this embodiment onto the refrigeration container 101, and ensure that the refrigeration container 101 is sealed at its mouth to form a complete heat exchange system (i.e., a heat exchanger for cryoablation equipment).

[0052] 2. Connect the inlet pipe 122 to the gas source and the outlet pipe 123 to the surgical instrument, and turn on the gas source to support the working requirements of the surgical instrument. At this time, the internal pressure of the heat exchange mechanism 12 is greater than the internal pressure of the refrigeration chamber 102, so that the one-way valve 132 is in a closed state and the medium in the heat exchange mechanism 12 cannot pass through the one-way valve 132 and enter the refrigeration chamber 102. After the operation is completed, the surgical instrument is separated from the catheter connector 124 of the outlet pipe 123.

[0053] 3. Since positive pressure is generated inside the refrigeration chamber 102 of the refrigeration container 101 due to the volatilization of the cooling medium, the outlet pipe 123 is connected to the air to eliminate the internal positive pressure of the heat exchange mechanism 12, so that the air pressure in the rear section of the anti-icing pipeline 13 (i.e. the section between the one-way valve 132 and the first branch pipe port 133) is lower than that in the front section (i.e. the section between the second branch pipe port 134 and the one-way valve 132), so that the one-way valve 132 is opened to connect the anti-icing pipeline 13, and the volatilized cooling medium gas in the refrigeration chamber 102 can be discharged into the air through the second branch pipe port 134-one-way valve 132-first branch pipe port 133-outlet pipe 123-duct joint 124 in sequence, and achieve stable outward exhaust in the above-mentioned interval pipeline to prevent moisture in the air from entering the outlet pipe 123 or the duct joint 124, thereby achieving the purpose of avoiding ice blockage.

[0054] 4. When it is needed again, connect the surgical instrument to the catheter connector 124 and wait for the system to stabilize before performing the next cryoablation operation.

[0055] Therefore, the device in this embodiment, in addition to having the function of preventing ice blockage, is automatically triggered in operation and does not require the operator to perform any active operation, which can also greatly reduce the labor intensity during the operation.

[0056] Embodiment 2

[0057] like Figure 6 As shown, an anti-icing and blocking heat exchange system device has a main structure that is the same as that of the first embodiment, except that in this embodiment, a controlled valve component 135 is used to replace the one-way valve 132. The controlled valve component 135 can be a solenoid valve or a pneumatic valve, which is connected to a control unit 136 to be controlled to be opened or closed. For example, when the controlled valve component 135 is a solenoid valve, it is electrically connected to the control unit 136.

[0058] In this embodiment, the controlled valve element 135 is a two-position three-way solenoid valve.

[0059] Preferably, the control unit 136 has a sensor device for detecting the connection status of the surgical instrument and the catheter connector 124. When the two are connected, the control unit 136 closes the controlled valve 135, and when the two are disconnected, the control unit 136 opens the controlled valve 135 to conduct the anti-icing pipeline 13. There are two ways for the control unit 136 to retrieve the connection status of the surgical instrument and the catheter connector 124. One is to detect whether the physical connection structure of the two is connected, such as using a docking electrode to detect whether a current is generated to detect whether it is connected, or using a touch switch set on the catheter connector 124 to detect whether it is connected; the second is to detect or judge whether it is connected by detecting the internal pressure of the outlet pipe 123. Since the internal pressure of the outlet pipe 123 during heat exchange is significantly greater than the internal air pressure during emptying or anti-blocking purge, it is also feasible to judge by pressure detection.

[0060] Of course, in other embodiments, a ball valve or other valve or a touch switch may be used to replace the one-way valve 132 or the controlled valve member 135, so that manually opening the anti-blocking purge to achieve the purpose of anti-blocking is also feasible.
