Description

Technical Field

[0001] The present invention relates to the technical field of sealing, and particularly to a medical device sealing detection device with an intelligent sensor. Background Art

[0002] A medical device sealing detection device with an intelligent sensor is a device used to detect whether the combined cap of an infusion container is sealed well. Such a device is very important in the fields of medicine, pharmacy, and biotechnology because drugs and liquids need to be stored and transported under sterile and sealed conditions to ensure the effectiveness of the drugs and the safety of patients.

[0003] The patent with the patent announcement number CN204008025U relates to a combined cap sealing detection device for a plastic infusion container. The combined cap sealing detection device includes: a water tank; an outer cap fixing assembly disposed inside the water tank, including: a base for supporting the outer cap, the base being fixed on the bottom wall of the water tank and having an air inflation passage inside. The air inflation passage extends from the bottom wall of the base towards the top wall and forms an air inflation hole on the top wall of the base. The outer cap opening is disposed opposite to the air inflation hole on the base; a fixing member for fixing the outer cap, the fixing member being hermetically connected to one end of the top wall of the base to fix the outer cap between the base and the fixing member; a test gas supply device connected to the air inflation passage. This detection device uses the outer cap fixing assembly to fix the outer cap and applies an external force to the outer cap through the air inflation passage inside the base, so that the poorly welded or fine cracks on the outer cap can be destroyed or magnified and exposed.

[0004] In the above patent, the outer cap is fixed by the outer cap fixing assembly, and an external force is applied to the outer cap through the air inflation passage inside the base, so that the poorly welded or fine cracks on the outer cap can be destroyed or magnified and exposed. However, during the process of detecting the sealing performance, it is necessary to evacuate the gas inside the sealed tank and then observe whether the pressure rod leaks. At the same time, some harmful gases may volatilize from the stored solution. If the tank contains harmful or dangerous substances, suddenly opening the tank body may cause the rapid release of harmful substances into the environment, which may pose a danger to personnel and the environment. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a medical device sealing detection device with an intelligent sensor, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A medical device sealing detection device with intelligent sensors, including a sealed tank, further including a detection device and a decompression device. A sealing cover is provided on the top of the sealed tank. Among them, the detection device includes a delivery pipe, an air extraction box, an air extractor, a first chute, a pneumatic rod, an L-shaped short rod, a screw rod, and an activated carbon plate. The gas inside the sealed tank is evacuated by the downward movement of the output end of the air extractor. When the gas inside the sealed tank is evacuated, it will drive the pneumatic rod to move into the sealed tank. By observing whether the pneumatic rod moves, if the pneumatic rod moves into the sealed tank, it indicates good sealing and no leakage. The delivery pipe is fixedly penetrated through the surface of the sealed tank. The air extraction box is fixedly installed at the bottom of the delivery pipe. A groove is provided on the conveyor belt of the air extraction box. The air extractor is fixedly installed at the bottom inner wall of the air extraction box. The first chute is fixedly penetrated through the surface of the sealed tank. The pneumatic rod is slidably installed on the inner wall of the first chute. The L-shaped short rod is fixedly installed at the delivery end of the air extractor. The screw rod is slidably installed inside the groove. The L-shaped short rod is slidably installed on the surface of the screw rod. The activated carbon plate is fixedly installed at the top of the screw rod. The activated carbon plate is rotatably installed on the inner wall of the air extraction box. When the output end of the air extractor moves downward, it will drive the L-shaped short rod to move downward. The downward movement of the L-shaped short rod will drive the screw rod to rotate. The rotation of the screw rod will drive the activated carbon plate to rotate. By the rotation of the activated carbon plate, the surface area of contact between the harmful gas and the activated carbon can be increased, and the adsorption efficiency can be improved.

[0007] According to the above technical solution, a first spring is provided between the pneumatic rod and the first chute. An air inlet hole is provided in the output end and the fixed end of the air extractor. A one-way valve is provided inside the air inlet hole. The first spring drives the pneumatic rod to reset, preventing it from affecting subsequent sealing detection. By setting the one-way valve, gas backflow is prevented, and the sealing detection is inaccurate.

[0008] According to the above technical solution, the decompression device includes an air delivery pipe, a hair dryer, a valve rod, and a valve plate. The valve rod is manually rotated. The rotation of the valve rod will drive the valve plate to rotate. The rotation of the valve plate opens the outlet of the air delivery pipe. Gas is delivered into the sealed tank by the hair dryer. The air delivery pipe is fixedly penetrated through the surface of the sealed tank. The hair dryer is fixedly installed at the bottom of the air delivery pipe. The valve rod rotates through the top of the air delivery pipe. The valve plate is fixedly installed at the bottom of the valve rod, preventing the sudden fluctuation of the liquid that may occur when the sealing cover is opened in a vacuum state, which may affect the stability of the liquid and even cause leakage.

[0009] According to the above technical solution, a bracket is fixedly installed on the inner wall of the gas pipeline. A fan is rotatably installed on the surface of the bracket. A T-shaped rod is fixedly installed on the surface of the fan. A telescopic port is fixedly installed on the gas pipeline. An arc-shaped block is fixedly installed on the inner wall of the telescopic port. When the hair dryer conveys gas into the sealed tank, it will drive the fan to rotate. The rotation of the fan will drive the T-shaped rod to rotate. The rotation of the T-shaped rod will contact the arc-shaped block. The T-shaped rod will push the arc-shaped block to move towards the inner wall of the gas pipeline. By making the telescopic port larger or smaller, when the gas rate is relatively fast or the pressure is relatively high, this may cause pressure shock to the structure and sealing performance of the sealed tank, and even lead to leakage or damage.

[0010] According to the above technical solution, a limiting device and a sealing device are further included. The limiting device includes a rotating rod, a sliding rod, a clamping groove and a clamping block. By manually rotating the valve rod to drive the rotating rod to rotate, the rotating rod will contact the inclined surface of the sliding rod. The rotating rod will drive the sliding rod to move downward. The downward movement of the sliding rod will drive the clamping groove to move downward. The rotating rod is fixedly installed on the surface of the valve rod. The sliding rod is slidably installed on the surface of the sealed tank. The clamping groove is fixedly installed at the top of the sliding rod. The clamping block is fixedly installed on the surface of the sealing cover. A second spring is arranged between the sliding rod and the sealed tank. To prevent that when the sealed tank is not depressurized, the rate or pressure of the gas introduced manually when opening the sealing cover is relatively fast or high, which may cause pressure shock to the structure and sealing performance of the tank body, resulting in leakage or damage. The second spring drives the sliding rod to reset to limit the sealing cover.

[0011] According to the above technical solution, a trapezoidal plate is fixedly installed on the surface of the sliding rod. A second chute is fixedly penetrated through the surface of the sealed tank. A sealing plate is fixedly installed on the inner wall of the second chute. A round hole is opened on the surface of the sealing plate. A pneumatic sliding rod is slidably installed in the inner wall of the round hole. A third spring is arranged between the round hole and the pneumatic sliding rod. The downward movement of the sliding rod will drive the trapezoidal plate to move downward. The downward movement of the trapezoidal plate will contact the surface of the pneumatic sliding rod. The trapezoidal plate will push the pneumatic sliding rod to move towards the inside of the sealed tank. The movement of the pneumatic sliding rod towards the inside of the sealed tank will cause it to disengage from contact with the sealing plate, gradually balance the internal and external pressures before opening, reduce the pressure difference, and reduce the resistance when opening the sealing cover. The third spring drives the pneumatic sliding rod to reset to prevent gas leakage and unqualified sealing performance.

[0012] According to the above technical solution, the sealing device includes a heater, an L-shaped block, a sealing ring, a rotary handle, and a control switch. Manually rotate the rotary handle to close the sealing cover. The rotation of the rotary handle will drive the rotation of the sealing cover, and the rotation of the sealing cover will drive the rotation of the L-shaped block, preventing the internal air pressure from being too high, which may cause the sealing cover to burst suddenly, greatly affecting the storage and sealing of the solution, and may cause the solution to lose its activity and effectiveness. The heater is fixedly installed on the top of the sealing cover, the L-shaped block is fixedly installed on the bottom of the sealing cover, the sealing ring is fixedly installed on the bottom of the sealing cover, the rotary handle is fixedly installed on the surface of the sealing cover, and the control switch is fixedly installed on the surface of the pneumatic rod. The heater heats the sealing ring, and the sealing ring expands when heated. The sealing effect of the sealing cover is better through the expansion of the sealing ring. When the pneumatic rod moves towards the inside of the sealing tank, it will drive the control switch to move towards the inside of the sealing tank. The control end of the control switch is squeezed by the expanded sealing ring, and the heater is turned off through the control switch to prevent the heater from continuously heating and causing the sealing ring to damage the tank mouth, resulting in damaged sealing.

[0013] According to the above technical solution, a heat conduction tube is arranged between the heater and the sealing ring. The control switch is electrically connected to the heater. The sealing ring is heated by driving through the heat conduction tube, and the heater switch is controlled through the electrical connection between the control switch and the heater.

[0014] The present invention provides a medical device sealing detection device with an intelligent sensor. It has the following beneficial effects: (1) For the medical device sealing detection device with an intelligent sensor, the gas inside the sealing tank is evacuated by a vacuum pump for detection, and it is observed whether the pneumatic rod moves. The movement of the pneumatic rod towards the inside of the sealing tank indicates good sealing performance. At the same time, some volatile liquids may be stored inside the sealing tank, and volatilization may produce some harmful gases. When the vacuum pump evacuates the gas, it drives the activated carbon plate to rotate, which can increase the surface area of contact between the harmful gas and the activated carbon, improve the adsorption efficiency, and prevent the sudden opening of the sealing cover from possibly causing the rapid release of harmful substances into the environment, which may pose a danger to personnel and the environment.

[0015] (2) For the medical device sealing detection device with an intelligent sensor, the blower is made to deliver gas towards the inside of the sealing tank by manually rotating the valve rod, preventing the sudden fluctuation of the liquid that may occur when opening the sealing cover in a vacuum state, which may affect the stability of the liquid and even cause leakage. At the same time, when the blower delivers gas towards the inside, it drives the fan to rotate, and the rotation of the fan drives the expansion port to intermittently become larger and smaller, preventing the gas rate from being too fast or the pressure from being too high, which may cause a pressure impact on the structure and sealing performance of the sealing tank, and even cause leakage or damage.

[0016] (3) For the medical device sealing detection device with intelligent sensors, when the valve rod is rotated simultaneously to drive the rotating rod to rotate, the rotating rod will drive the sliding rod to move downward, causing the clamping groove to disengage from the limit of the clamping block, enabling the user to open the sealing cover. This prevents the introduction of gas at a relatively high rate or pressure when the sealed tank is not depressurized, which may cause pressure shock to the structure and sealing performance of the tank body, resulting in leakage or damage. At the same time, when the sliding rod moves downward, it will drive the trapezoidal plate to descend, which will drive the pneumatic sliding rod to move into the sealed tank, gradually balancing the internal and external pressures before opening and reducing the pressure difference, thereby reducing the resistance when the sealing cover is opened.

[0017] (4) For the medical device sealing detection device with intelligent sensors, through the L-shaped sliding groove provided at the top of the sealed tank, when the sealing cover is closed, the sealing cover is rotated to make the L-shaped block snap into the L-shaped sliding groove, preventing the internal air pressure from being too high and causing the sealing cover to suddenly burst open, which has a great impact on the storage and sealing of the solution and may cause the solution to lose its activity and be unable to function. At the same time, when the sealing cover is closed, the heater will heat the sealing ring. The heated sealing ring will expand, making the sealing performance of the sealing cover better. At the same time, when the pneumatic rod moves into the sealed tank, it will drive the control switch to move inward. The expanded sealing ring will contact the control switch to turn off the heater, preventing the heater from continuously heating and causing the sealing ring to damage the bottle mouth.

The downward movement of the L-shaped short rod 36 will drive the screw rod 37 to rotate. The rotation of the screw rod 37 will drive the activated carbon plate 38 to rotate. By rotating the activated carbon plate 38, the surface area between the harmful gas in contact with the activated carbon can be increased, and the adsorption efficiency can be improved. An intelligent sensor device is provided on the top of the sealing cover 2. The intelligent sensor device includes a pressure sensor and a humidity sensor.

[0022] A first spring is provided between the pneumatic rod 35 and the first chute 34. An air inlet hole is provided at the output end and the fixed end of the air extractor 33, and a one-way valve is provided inside the air inlet hole.

By setting the one-way valve, gas backflow is prevented and the sealing detection is inaccurate.

[0023] The decompression device includes an air delivery pipe 41, a hair dryer 42, a valve rod 43, and a valve plate 44.

When the gas inside the sealed tank 1 is evacuated, it will drive the air pressure rod 35 to move towards the inside of the sealed tank 1. By observing whether the air pressure rod 35 moves, the movement of the air pressure rod 35 towards the inside of the sealed tank 1 indicates good sealing and no leakage. At the same time, when the output end of the air extractor 33 moves downward, it will drive the L-shaped short rod 36 to move downward. The downward movement of the L-shaped short rod 36 will drive the screw rod 37 to rotate. The rotation of the screw rod 37 will drive the activated carbon plate 38 to rotate. By rotating the activated carbon plate 38, the surface area in contact between the harmful gas and the activated carbon can be increased, the adsorption efficiency can be improved, and it can prevent the sudden release of harmful substances into the environment that may occur when the sealed cover 2 is suddenly opened, which may pose a danger to personnel and the environment.

[0026] When it is necessary to open the sealed cover 2, manually rotate the valve rod 43. The rotation of the valve rod 43 will drive the valve plate 44 to rotate. The rotation of the valve plate 44 opens the outlet of the gas pipeline 41. Gas is conveyed into the sealed tank 1 through the hair dryer 42 to prevent the sudden fluctuation of the liquid that may occur when opening the sealed cover 2 in a vacuum state, which may affect the stability of the liquid and even cause leakage. At the same time, when the hair dryer 42 conveys gas into the sealed tank 1, it will drive the fan 46 to rotate. The rotation of the fan 46 will drive the T-shaped rod 47 to rotate. The rotation of the T-shaped rod 47 will contact the arc-shaped block 49. The T-shaped rod 47 will push the arc-shaped block 49 to move towards the inner wall of the gas pipeline 41. The movement of the arc-shaped block 49 towards the inner wall of the gas pipeline 41 will drive the telescopic port 48 to expand and contract towards the inner wall of the gas pipeline 41. By making the telescopic port 48 larger or smaller, when the gas rate is relatively fast or the pressure is relatively high, this can prevent pressure shocks to the structure and sealing performance of the sealed tank 1, and even prevent leakage or damage.

[0027] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a limiting device and a sealing device are further included. The limiting device includes a rotating rod 51, a sliding rod 52, a clamping groove 53 and a clamping block 54. By manually rotating the valve rod 43 to drive the rotating rod 51 to rotate, the rotation of the rotating rod 51 will contact the inclined surface of the sliding rod 52, and the rotating rod 51 will drive the sliding rod 52 to move downward. The downward movement of the sliding rod 52 will drive the clamping groove 53 to move downward, and the downward movement of the clamping groove 53 will release the limit on the clamping block 54, enabling the user to manually open it. The rotating rod 51 is fixedly installed on the surface of the valve rod 43, the sliding rod 52 is slidably installed on the surface of the sealing tank 1, the clamping groove 53 is fixedly installed at the top of the sliding rod 52, and the clamping block 54 is fixedly installed on the surface of the sealing cover 2. A second spring is provided between the sliding rod 52 and the sealing tank 1 to prevent the rate of gas introduction or pressure from being too high when the sealing cover 2 is manually opened without relieving the pressure in the sealing tank 1. This may cause pressure shock to the structure and sealing performance of the tank body, resulting in leakage or damage. The second spring drives the sliding rod to reset to limit the sealing cover 2.

[0028] A trapezoidal plate 55 is fixedly installed on the surface of the sliding rod 52, and a second sliding groove 56 is fixedly penetrated through the surface of the sealing tank 1.

A third spring is provided between the round hole and the pneumatic sliding rod 57. The downward movement of the sliding rod 52 will drive the trapezoidal plate 55 to move downward, and the downward movement of the trapezoidal plate 55 will contact the surface of the pneumatic sliding rod 57. The trapezoidal plate 55 will push the pneumatic sliding rod 57 to move towards the inside of the sealing tank 1. The movement of the pneumatic sliding rod 57 towards the inside of the sealing tank 1 will cause it to disengage from contact with the sealing plate 58, allowing the gas to be discharged through the second sliding groove 56, gradually balancing the internal and external pressures before opening, reducing the pressure difference, and reducing the resistance when the sealing cover 2 is opened. The third spring drives the pneumatic sliding rod 57 to reset to prevent gas leakage and unqualified sealing performance.

[0029] The sealing device includes a heater 61, an L-shaped block 62, a sealing ring 63, a rotary handle 64 and a control switch 65. Manually rotate the rotary handle 64 to close the sealing cover 2. The rotation of the rotary handle 64 will drive the rotation of the sealing cover 2. The rotation of the sealing cover 2 will drive the rotation of the L-shaped block 62. The rotation of the L-shaped block 62 will get stuck in the inner wall of the L-shaped chute, preventing the internal air pressure from being too high, which may cause the sudden bursting of the sealing cover 2, greatly affecting the storage and sealing of the solution, and may cause the solution to lose its activity and effectiveness. The heater 61 is fixedly installed on the top of the sealing cover 2. The L-shaped block 62 is fixedly installed on the bottom of the sealing cover 2. The sealing ring 63 is fixedly installed on the bottom of the sealing cover 2. The rotary handle 64 is fixedly installed on the surface of the sealing cover 2. The control switch 65 is fixedly installed on the surface of the pneumatic rod 35. The heater 61 heats the sealing ring 63. The sealing ring 63 will expand when heated. The sealing effect of the sealing cover 2 is better through the expansion of the sealing ring 63. When the pneumatic rod 35 moves towards the inside of the sealing tank 1, it will drive the control switch 65 to move towards the inside of the sealing tank 1. The movement of the control switch 65 towards the inside of the sealing tank 1 will contact the surface of the expanded sealing ring 63. The control end of the control switch 65 is squeezed by the expanded sealing ring 63, and the heater 61 is turned off through the control switch 65 to prevent the heater 61 from continuously heating and causing the sealing ring 63 to damage the tank opening, resulting in damaged sealing.

[0030] A heat-conducting pipe is arranged between the heater 61 and the sealing ring 63. The control switch 65 and the heater 61 are electrically connected. The sealing ring 63 is heated through the heat-conducting pipe, and the switch of the heater 61 is controlled through the electrical connection between the control switch 65 and the heater 61.

[0031] When this embodiment works, manually rotate the valve rod 43 to drive the rotation of the rotating rod 51. The rotation of the rotating rod 51 will contact the inclined surface of the sliding rod 52. The rotating rod 51 will drive the sliding rod 52 to move downward. The downward movement of the sliding rod 52 will drive the downward movement of the card slot 53. The downward movement of the card slot 53 will release the limit on the clamping block 54, enabling the user to manually open it, preventing the rate of gas introduction or pressure from being too high when manually opening the sealing cover 2 without relieving the pressure in the sealing tank 1, which may cause pressure shock to the structure and sealing performance of the tank body, resulting in leakage or damage. At the same time, the downward movement of the sliding rod 52 will drive the downward movement of the trapezoidal plate 55. The downward movement of the trapezoidal plate 55 will contact the surface of the pneumatic sliding rod 57. The trapezoidal plate 55 will push the pneumatic sliding rod 57 to move towards the inside of the sealing tank 1. The movement of the pneumatic sliding rod 57 towards the inside of the sealing tank 1 will disengage from the contact with the sealing plate 58, enabling the gas to be discharged through the second chute 56, gradually balancing the internal and external pressures before opening, reducing the pressure difference, and reducing the resistance when the sealing cover 2 is opened.

[0032] The sealing cover 2 is closed by manually rotating the turning handle 64. Rotating the turning handle 64 will drive the sealing cover 2 to rotate. Rotating the sealing cover 2 will drive the L-shaped block 62 to rotate. The rotation of the L-shaped block 62 will be stuck into the inner wall of the L-shaped chute, preventing the internal air pressure from being too large and causing the sealing cover 2 to suddenly burst open, which has a great impact on the storage and sealing of the solution, and may cause the solution to lose its activity and effectiveness. At the same time, the heater 61 heats the sealing ring 63. The sealing ring 63 will expand when heated. The sealing effect of the sealing cover 2 is better through the expansion of the sealing ring 63. When the air pressure rod 35 moves towards the inside of the sealing tank 1, it will drive the control switch 65 to move towards the inside of the sealing tank 1. When the control switch 65 moves towards the inside of the sealing tank 1, it will contact the surface of the expanded sealing ring 63. The control end of the control switch 65 is squeezed by the expanded sealing ring 63, and the heater 61 is turned off through the control switch 65 to prevent the heater 61 from continuously heating and causing the sealing ring 63 to damage the tank opening and resulting in damaged sealing.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
