Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an infusion hose and a heat-insulating hose cover. Background Art

[0002] In the medical field, hoses are important connecting and transporting components and are widely used in basic scientific research, medical health, materials and chemical industry, mechanical electronics and other fields. These hoses not only play the role of connection, compensation, sealing and shock absorption, but also need to have good thermal insulation performance to prevent excessive heat loss when transporting high-temperature or low-temperature media. However, existing hoses are insufficient in thermal insulation, especially in complex and changeable working environments. Its thermal insulation effect is often difficult to meet actual needs. In order to solve this problem, some thermal insulation solutions for hoses have emerged, such as thermal insulation sleeves, thermal insulation layers, etc. However, these solutions often have problems such as complex installation, unstable thermal insulation effect, and poor durability.

[0003] A silicone rubber infusion heating and insulation tube with announcement number CN110585532A is characterized in that it includes a silicone rubber heating tube, a power cable, an insulation sleeve, an insulating high-temperature resistant heat shrink tube, a first composite fiber heating wire, a second composite fiber heating wire, a third composite fiber heating wire, a fourth composite fiber heating wire, a first NTC temperature sensor, a second NTC temperature sensor, foamed liquid silicone rubber, a first flexible magnetic sheet and a second flexible magnetic sheet. The power cable is provided with a first wire, a second wire, a third wire, a fourth wire and a fifth wire. The power cable is connected to one end of the silicone rubber heating tube, and the first NTC temperature sensor and the second NTC temperature sensor are both located inside the silicone rubber heating tube at one end away from the power cable.

[0004] An infusion tube with announcement number CN117427239A has a relative distal end and a proximal end, the infusion tube includes a first tube body, a second tube body and a connecting assembly, the proximal end of the first tube is connected to an infusion bag and has a first channel for circulation of liquid medicine; the distal end of the second tube is provided with an infusion needle and has a second channel for circulation of liquid; the connecting assembly includes a first connector and a second connector, the first connector is arranged at the distal end of the first tube body; the second connector is arranged at the proximal end of the second tube body and is detachably connected to the first connector, and the two have a mutually connected combined state and a relative separated state, an elastically deformable blocking member is arranged in the second connector, the blocking member has a closed state for blocking the second channel, and an open state for opening the second channel.

[0005] Based on the above scheme, the insulating hose cover needs to be filled with insulating liquid into the internal cavity when in use, and the transmitted medicine liquid is insulated by heat exchange. However, in actual use, the temperature of the insulating liquid will continue to drop. When the temperature drops to a certain level, it is not enough for the medicine liquid to reach the set temperature and is insufficient to support subsequent use. If the insulating liquid is replaced at this time, the heat of the insulating liquid will not be completely used up, resulting in waste. When the temperature of the insulating liquid is completely cooled, since the medicine liquid is always being transmitted, the passage is cut off at this time, and there is still residual liquid inside the insulating hose cover, which cannot be insulated, thus affecting subsequent use. Summary of the invention

The bottom surface of the rotating component is connected to a spiral air guide tube, and the spiral air guide tube is spring-shaped, and the upper and lower ends of the spiral air guide tube are provided with first pressure valves.

[0008] The air storage component can collect the hot air inside the insulation liquid, and after the temperature of the insulation liquid drops, the hot air is discharged to further improve the insulation efficiency through the hot air, thereby avoiding the situation where the insulation effect is poor due to the decrease in the temperature of the insulation liquid. The rotating component can make the spiral air guide tube rotate, driving the insulation liquid inside the cavity to move, thereby avoiding the failure to completely use up the internal heat of the insulation liquid during the heat exchange process.

[0014] Preferably, the thermal insulation sleeve comprises an outer layer and an inner layer, and the wall thickness of the outer layer is greater than the wall thickness of the inner layer.

[0015] The present invention also provides an infusion hose, comprising a catheter and a thermal insulation hose cover, wherein a puncture device is provided at the upper end of the catheter, an intravenous infusion needle is provided at the lower end of the catheter, a flow regulator and a drip bucket are provided in the middle of the catheter, and the thermal insulation hose cover is provided between the puncture device and the drip bucket.

[0016] Technical effects of the present invention: 1. The insulation cover of the present invention adopts advanced soft and affinity insulation material. The insulation cover material has good flexibility, transparency, biosafety, temperature resistance and corrosion resistance. It can resist the erosion of the insulation hose cover by harsh environment and ensure the stability of the internal medium and the liquid in the passage.

[0019] 4. The present invention can make the spiral air duct drive the thermal insulation liquid to move through the cooperation between the rotating component and the spiral air duct, so as to promote the heat dissipation of the thermal insulation liquid and make full use of the heat, thereby avoiding the situation where the temperature of the thermal insulation liquid drops and the thermal insulation cannot be guaranteed at this time. At the same time, under the action of centrifugal force, the spiral air duct can be stretched to make the stirring range wider, thereby avoiding the situation where the stirring is not in place, resulting in the heat inside the thermal insulation liquid cannot be completely used up, causing waste.

[0020] 5. Under the action of the distance sensor, the present invention can delay the temperature of the insulation liquid at this time in real time and make corresponding adjustments according to different temperatures. When the first threshold is reached, the rotating component drives the spiral air duct to move, prompting the insulation liquid to dissipate heat and fully utilize the heat. When the second threshold is reached, the signal is transmitted to the inside of the computer. The computer simultaneously transmits signals to the electronic valve and the alarm, thereby prompting the alarm to sound an alarm and the electronic valve to cut off the passage.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] First embodiment The present invention provides Figures 1 to 8 An insulating hose cover shown includes an insulating cover 1. The insulating cover 1 is made of advanced soft insulating material. The insulating cover material has good flexibility, transparency, biosafety, temperature resistance and corrosion resistance. It can resist the erosion of the insulating hose cover by harsh environment and ensure the stability of the internal medium and the liquid in the passage. The length of the insulating cover can be customized according to the required diameter and length of the passage. It is suitable for different use environments. The insulating hose cover has various specifications: lengths ranging from 5cm to 3m, inner diameters ranging from 10mm to 1cm, and a cavity 2 is opened inside the insulating cover 1. A set constant temperature circulating medium is passed into the cavity 2, which can effectively prevent heat transfer and reduce heat loss.

[0025] An air storage component 3 is provided on the upper part of the top wall of the cavity 2. The air storage component 3 can collect the hot air inside the insulation liquid. After the temperature of the insulation liquid drops, the hot air is discharged, and the insulation efficiency is further improved by the hot air, so as to avoid the situation where the insulation liquid temperature drops and the insulation effect is poor. An adjustment component 4 is provided in the middle part of the inner wall of the cavity 2. The adjustment component 4 can be adjusted according to the internal temperature of the insulation sleeve 1. When the temperature drops to a first threshold value, the rotating component 5 drives the spiral air guide tube 306 to rotate, and drives the insulation liquid inside the cavity 2 to move, so that the remaining heat of the insulation liquid is quickly released, so as to avoid the insulation effect from deteriorating at this time, so that the transmitted liquid cannot reach the predetermined temperature, and unnecessary trouble occurs. When the temperature drops to a second threshold value, the electronic valve 11 cuts off the transmitted liquid, so as to avoid the liquid that cannot reach the predetermined temperature from continuing to be transmitted, and at the same time, the hot air inside the air storage component 3 is discharged, and the remaining liquid is made to reach the predetermined temperature through the hot air, so as to avoid affecting the follow-up.

[0026] The air storage component 3 includes an air storage box 301, and a partition 302 is slidably connected to the interior of the air storage box 301. The partition 302 can divide the air storage box 301 into two spaces. The space located in the upper part is relatively sealed. When the partition 302 rises, the air in the upper space can be compressed to increase the internal air pressure. At the same time, when the partition 302 rises, the internal pressure of the lower space is reduced. Under the action of air pressure, hot air can be filled into the lower space through the first air inlet pipe 303, so as to achieve the purpose of storing hot air. When the force of the partition 302 rising disappears, under the action of air pressure, the air in the lower space is filled with hot air. Down, the partition 302 can be quickly reset, so that the gas inside the lower space can be transmitted to the inside of the spiral air guide 306. A group of first air inlet pipes 303 arranged in a circle are provided on the bottom surface of the air storage box 301, and the inner diameter of each first air inlet pipe 303 gradually increases from top to bottom, which can make the first air inlet pipe 303 collect hot air and cover a larger area, and the efficiency of absorbing hot air is accelerated. A one-way valve 304 is provided inside each first air inlet pipe 303. The one-way valve 304 can allow hot air to enter the inside of the air storage box 301, and prevent hot air from being discharged from the one-way valve 304.

[0027] The bottom surface of the air storage box 301 is connected with a rotating component 5. The rotating component 5 and the air storage box 301 are directly provided with a group of second pressure valves 305 arranged in a circle. The rotating component 5 can rotate the spiral air guide tube 306 to drive the heat-insulating liquid inside the cavity 2 to move, so as to avoid that the heat inside the heat-insulating liquid is not completely used up during the heat exchange process. When the pressure of the second pressure valve 305 reaches a certain threshold, it can be opened to connect the air storage box 301 and the rotating component 5 to achieve the purpose of air delivery. The bottom surface of the rotating component 5 is connected with the spiral air guide tube 306, and the spiral air guide tube 306 is spring-shaped. The rotating component 5 can drive the spiral air guide tube 306 to rotate. Under the action of centrifugal force, the spiral air guide tube 306 can be elongated to make the stirring range wider, so as to avoid the situation where the stirring is not in place. The situation results in that the heat inside the thermal insulation liquid cannot be completely used up, resulting in waste. The upper and lower ends of the spiral air duct 306 are both provided with a first pressure valve 307. When the suction force received by the first pressure valve 307 at the upper end reaches a threshold value, it can be opened to allow the gas inside the spiral air duct 306 to be introduced into the air storage box 301 and mixed with the collected hot air, so that the gas inside the spiral air duct 306 is quickly heated up to prepare for subsequent use. When the pressure of the first pressure valve 307 at the upper end reaches a threshold value, it can be opened again to allow the hot air to enter the spiral air duct 306 through the first pressure valve 307, so that the hot air moves along the trajectory of the spiral air duct 306, constantly contacts the thermal insulation liquid here and the liquid medicine inside the infusion hose, so that the temperature of the liquid medicine is increased, thereby avoiding the situation where the transmitted liquid medicine fails to reach the predetermined temperature.

[0028] The rotating component 5 includes an air storage ring 501, through which hot air can enter the interior of the spiral air duct 306 below to achieve the purpose of hot air transmission. A circular groove 502 is provided on the bottom surface of the air storage ring 501, and a rotating disk 503 is slidably connected inside the circular groove 502. A group of fan blades 504 arranged in a circle are provided on the upper surface of the rotating disk 503, and each fan blade 504 is inclined. When the hot air inside the air storage box 301 is pressurized and enters the air storage ring 501, the fan blades 504 are blown to rotate, causing the spiral air duct 306 below to rotate, thereby achieving the purpose of stirring the heat-insulating liquid. At the same time, when the fan blades 504 rotate, a certain suction force can be generated to accelerate the efficiency of hot air transmission.

[0029] The adjustment component 4 includes a sleeve 401, and a push plate 402 is slidably connected inside the sleeve 401. The push plate 402 can move according to the trajectory of the sleeve 401. The upper surface of the push plate 402 and the top wall of the sleeve 401 are provided with a spring 403. When the push plate 402 rises, the spring 403 can be compressed to generate a resetting elastic force. The bottom surface of the push plate 402 and the bottom wall of the sleeve 401 are filled with an expansion material. The expansion material expands according to the increase in temperature, pushing the push plate 402 to rise. When the temperature decreases, the expansion material contracts. Under the action of the spring 403, the push plate 402 is pushed downward. A distance sensor is provided on the upper surface of the push plate 402. The distance sensor can detect the distance between the push plate 402 and the top wall of the sleeve 401 in real time. The larger the distance between the two, the smaller the volume of the expansion material, which means that the temperature of the insulation liquid is lower and the insulation effect is worse. The smaller the distance, the larger the volume of the expansion material, which means that the temperature of the insulation liquid is higher and the insulation effect is better. The inner bottom wall of the air storage box 301 is provided with a ring-shaped air bag 6, and the upper surface of the air bag 6 is in contact with the bottom surface of the partition 302. A second air inlet pipe 7 is connected between the air bag 6 and the sleeve 401. When the expansion material expands due to the increase in temperature, under the action of extrusion, the push plate 402 is pushed to gradually move upward along the trajectory of the sleeve 401, so that the spring 403 above is compressed to produce a restoring elastic force. At the same time, due to the rise of the push plate 402, the space at the upper end of the sleeve 401 becomes smaller, so that the internal gas is compressed and the gas enters the air bag 6 through the second air inlet pipe 7, so that the air bag 6 expands and pushes the partition 302 to move upward. Under the action of negative pressure, the hot air can be collected into the air storage box 301 through the first air inlet pipe 303, thereby achieving the purpose of collecting hot air and preparing for subsequent use.

[0030] The outer surface of the insulation sleeve 1 is respectively provided with a water inlet 8 and a water outlet 9, and the right ends of the water inlet 8 and the water outlet 9 are threadedly connected with a cover plate 10, and the cover plate 10 can be freely disassembled, making it more convenient to replace the insulation liquid. At the same time, the cover plate 10 can effectively seal the water inlet 8 and the water outlet 9 to avoid overflow. An electronic valve 11 is provided at the upper end of the insulation sleeve 1, and an alarm is provided on the upper surface of the electronic valve 11. The electronic valve 11, the alarm and the distance sensor are all wirelessly connected to an external computer. When the distance detected by the distance sensor reaches a second threshold, it indicates that the insulation liquid needs to be replaced at this time. The electronic valve 11 is started to cut off the passage to prevent the subsequent continuous transmission of the medicine. At the same time, the alarm is triggered to warn that new insulation liquid needs to be added at this time.

[0031] The insulation sleeve 1 includes an outer layer 101 and an inner layer 102. The wall thickness of the outer layer 101 is greater than that of the inner layer 102. The outer layer 101 ensures that the heat loss of the insulation medium is small and the material is good, which prevents the external environment from corroding the insulation layer. The inner layer 102 ensures that the insulation medium quickly, effectively and long-term heats up the liquid in the flow path, and provides good thermal conductivity, necessary mechanical strength and shape stability. The insulation sleeve 1 adopts an integrated design with detachable connecting devices at both ends. The operator can easily connect the insulation sleeve 1 to the remaining hoses or wirelessly connect the insulation sleeve 1 without complicated installation steps, and the sealing is good. The length of the insulation sleeve 1 can be customized according to the diameter and length required by the passage, and is suitable for different environments.

[0032] The present invention also provides an infusion hose, comprising a catheter and a thermal insulation hose cover, wherein a puncture device is provided at the upper end of the catheter, an intravenous infusion needle is provided at the lower end of the catheter, a flow regulator and a drip bucket are provided in the middle of the catheter, and the thermal insulation hose cover is provided between the puncture device and the drip bucket.

[0033] In actual use, the water inlet 8 is opened by rotating the cover 10, and by connecting the output end of a specific tool with the water inlet 8, the tool is started to add a proper amount of insulation liquid into the insulation sleeve 1, which can effectively prevent heat transfer and reduce heat loss. After filling, the water inlet 8 is closed again to avoid overflow.

[0034] Under the high temperature of the heat-insulating liquid, the expansion material inside the sleeve 401 is caused to expand, causing an upward thrust on the upper push plate 402, causing the push plate 402 to gradually move upward along the trajectory of the sleeve 401, generating pressure on the upper spring 403 to contract, thereby causing the spring 403 to generate a restoring elastic force to prepare for subsequent resetting. At the same time, as the push plate 402 gradually rises, the space at the upper end of the sleeve 401 gradually becomes smaller, causing the gas inside the sleeve 401 to be compressed, causing the gas to enter the air bag 6 through the second air inlet pipe 7, causing the air inside the air bag 6 to increase and gradually expand, pushing the partition 302 to move upward. When the partition 302 gradually moves upward, the internal pressure of the lower space of the air storage box 301 is reduced, and under the action of air pressure, it can pass through the first air inlet pipe 303 to the lower space. The interior is filled with hot air, so as to achieve the purpose of storing hot air and prepare for subsequent use. At the same time, when the partition 302 rises, since the space located at the upper part is relatively sealed, the air inside the upper space can be compressed to increase the internal air pressure. When the force of the partition 302 rising disappears, the partition 302 can be quickly reset under the action of air pressure. When storing hot air, the air pressure inside the air storage box 301 decreases, so that the air pressure balance between the air storage ring 501, the spiral air guide tube 306 and the air storage box 301 is broken, prompting the first pressure valve 307 and the second pressure valve 305 at the upper end of the spiral air guide tube 306 to open, so that the gas inside the spiral air guide tube 306 is mixed with the hot air inside the air storage box 301 through the air storage ring 501, so that the temperature of the stored gas is constant, avoiding unevenness during insulation.

[0035] When the distance sensor detects that the distance between the push plate 402 and the sleeve 401 gradually increases to the first threshold, it indicates that the temperature of the heat preservation liquid is gradually decreasing and is insufficient to support the temperature of the transmitted liquid to reach the predetermined temperature, and the following adjustments are required: The expansion material is gradually cooled due to the decrease in the temperature of the heat-insulating liquid, so that the volume of the expansion material is gradually reduced. Under the elastic force of the upper spring 403, the push plate 402 is gradually lowered along the trajectory of the sleeve 401, causing the space at the upper end of the sleeve 401 to gradually increase, so that the air pressure inside the sleeve 401 decreases, and the gas inside the air bag 6 re-enters the sleeve 401 through the second air inlet pipe 7, so that the air inside the air bag 6 is reduced and gradually shrinks, which is not enough to support the upper partition 302. Under the interaction of the air pressure above the partition 302 and the gravity, the hot air below the partition 302 is squeezed. Due to the existence of the one-way valve 304, the compressed gas is gradually pressurized, so that the second pressure valve 305 Open it, so that the hot air can quickly pass through the second pressure valve 305 into the air storage ring 501. Under the action of wind, the fan blades 504 can be driven to gradually perform circular motion, so that the rotating disk 503 drives the spiral air guide tube 306 below to gradually rotate. Under the action of the spiral air guide tube 306, the thermal insulation liquid can be driven to move, which promotes the heat dissipation of the thermal insulation liquid and makes full use of the heat to avoid the situation where the temperature of the thermal insulation liquid drops and the thermal insulation cannot be guaranteed at this time. At the same time, under the action of centrifugal force, the spiral air guide tube 306 can be stretched to make the stirring range wider, so as to avoid the situation where the stirring is not in place, resulting in the heat inside the thermal insulation liquid cannot be completely used up, causing waste.

[0036] When the distance sensor detects that the distance between the push plate 402 and the sleeve 401 gradually increases to the second threshold value, it indicates that the heat preservation liquid is completely cooled and cannot be kept warm, and the following adjustments are required: First, the distance sensor transmits the signal to the inside of the computer, and the computer transmits signals to the electronic valve 11 and the alarm at the same time. When the electronic valve 11 receives the signal, it can close the passage for transmitting the liquid medicine to prevent the insulation sleeve 1 from being unable to insulate the liquid medicine and still transmitting it, thereby causing the liquid medicine to fail to reach the predetermined temperature. When the alarm receives the signal, it can trigger an alarm to warn that the insulation liquid needs to be replaced and normal work cannot be performed.

[0037] At this time, the air bag 6 has shrunk to its original volume. Due to the excessive gas under the partition 302, the gas collected in the air storage ring 501 gradually increases under the interaction of the upper air pressure and the suction of the fan blades 504, until the first pressure valve 307 above is reopened, allowing the stored hot air to quickly enter the spiral air duct 306. Under the constraint of the spiral air duct 306, the hot air moves along the trajectory of the spiral air duct 306, and the spiral air duct 306 contacts the inner layer 102, so that the transmitted medicine liquid can be insulated again. At the same time, when transmitting hot air, the spiral air duct 306 can generate a certain temperature itself, thereby transmitting a certain temperature to the nearby insulation liquid, avoiding the situation where the insulation liquid temperature is too low and excessive heat absorption occurs, affecting the insulation effect.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
