Description

Technical Field

[0001] This invention relates to the field of medical devices, particularly in the field of emergency cooling and auxiliary technology, and more particularly to a patient cooling and auxiliary nursing device for use in emergency internal medicine. Background Technology

[0002] Emergency cooling requires rapid and accurate temperature regulation. For patients with febrile seizures, heatstroke, or after cardiopulmonary resuscitation, every minute's body temperature affects their prognosis. Clinically, intravenous cooling combined with auxiliary cooling methods is necessary. Currently, auxiliary cooling devices used clinically are mainly divided into two types: basic physical cooling devices and intelligent circulating cooling devices. Basic physical cooling devices mainly include ice blankets, ice caps, and ice packs, with ice packs and ice caps being the most traditional, common, and lowest-cost cooling devices. In basic physical cooling devices, traditional ice packs melt rapidly during heat exchange with the body, requiring constant replacement. Intelligent circulating cooling devices address this by using circulating cooling tubing to exchange heat with the body. Often referred to as medical physical cooling instruments / emergency cooling machines / intelligent body temperature management systems, these are medical devices that achieve precise surface cooling through closed-loop circulating coolant, semiconductor refrigeration, and intelligent temperature control algorithms. Compared to traditional physical cooling devices such as cold hats and ice packs, intelligent circulating cooling devices can better control temperature, avoid freezing caused by traditional ice packs, and maintain a constant temperature through closed-loop circulation. However, intelligent circulating cooling devices have higher purchase, operating, and maintenance costs.

[0003] Intravenous cooling involves infusing 4°C refrigerated crystalloid solution, directly lowering core body temperature through the cold fluid. The cold fluid travels via veins, right heart, pulmonary circulation, and the entire body, achieving a cooling effect from the inside out. In clinical practice, a stent is needed to attach the infusion fluid during infusion. Current intravenous cooling procedures lack special insulation and protection measures after the infusion fluid is attached. In high-temperature environments, the infusion fluid may heat up before infusion due to heat exchange with the external environment, thus reducing its cooling effect.

[0004] Meanwhile, patients with febrile seizures, heatstroke, or those who have undergone cardiopulmonary resuscitation have poor body control. During the initial establishment of an infusion line, they cannot consciously control their hand position to maintain a convenient posture for needle insertion. After establishing an infusion line, the infusion site needs to be protected to prevent subsequent emergency procedures from interfering with the infusion. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the problem that when auxiliary devices in the prior art are used to cool patients by means of intravenous infusion, the infusion fluid will be heated by the environment before being injected, thereby reducing the cooling effect, the present invention provides an auxiliary nursing device for cooling patients in the emergency internal medicine department.

[0006] The technical solution adopted by this invention to solve its technical problem is: a patient cooling auxiliary nursing device for emergency internal medicine, used for placing through the hand of a patient receiving intravenous infusion via an infusion pump, comprising an annular sleeve and a heat-insulating component. The heat-insulating component includes a fixing frame connected to one end of the annular sleeve, with a through hole on the fixing frame. A clamping component is provided near one end of the annular sleeve through the through hole. Several fixing clips are provided on the outside of the annular sleeve, spirally distributed along the outside of the annular sleeve. After the infusion tubing of the infusion pump is clamped by the clamping component, it is positioned by the fixing clips. A heat-insulating pad is provided on the outside of the annular sleeve, the heat-insulating pad having a planar state when unfolded and a suction state when wrapped around the annular sleeve.

[0007] In the above solution, the combination of the ring sleeve and the heat insulation component allows for effective protection of the infusion site after the patient inserts their arm to be infused. Simultaneously, the clamping component effectively clamps and spirally positions the infusion tubing, and the heat insulation pad keeps the tubing warm, preventing excessive heat exchange between the infusion fluid and the external environment during infusion, which could reduce the cooling effect.

[0008] Preferably, the insulation pad has a pair of magnetic blocks at both ends after being unfolded, and a pull plate is provided on one side of the magnetic blocks. When the insulation pad is rolled into a cylindrical shape, the two pairs of magnetic blocks are attracted to each other in an alternating manner. Through the alternating attraction of the magnetic blocks, the attraction and disassembly are quick, allowing the insulation pad to quickly switch between a flat state and an attracted state.

[0009] Preferably, the clamping assembly includes two pairs of clamping plates, each clamping plate having a movable groove at its lower edge, the movable groove slidingly engaging with the fixed frame, a stop groove being provided on the groove wall of the movable groove, a connecting shaft being provided between the two clamping plates, and two pull ropes being connected to the outside of the connecting shaft, the free ends of the two pull ropes being connected to the top ends of the two clamping plates respectively.

[0010] Preferably, the annular sleeve is provided with a rotating support ring, and a pair of elastic pads are symmetrically connected to the inner side of the support ring, with a retaining plate connected to the opposite ends of the two elastic pads.

[0011] Preferably, the outer side of the support ring is connected to a movable plate via a slide rod, and both ends of the annular sleeve are provided with elastic rings. A fan-shaped groove is opened between the elastic ring near the fixed frame and the annular sleeve, and the slide rod is slidably engaged in the fan-shaped groove.

[0012] Preferably, a protective assembly is provided on one side of the fixed frame. This protective assembly includes three sets of corresponding fixed seats, positioning rings, and screws. The fixed seats are respectively located on the edge of the fixed frame. Protective plates are fixedly connected to the outer sides of the positioning rings at both ends, and an arc-shaped plate is fixedly connected to the outer side of the positioning ring in the middle. The screw is rotatably engaged with the fixed seat, and the inner wall of the positioning ring has threads that mate with the screw. The free end of the screw, after passing through the fixed seat, is screwed to the positioning ring. With the arrangement of the three sets of fixed seats, positioning rings, and screws, when the screw is screwed to the positioning ring, the screw and fixed seat can rotate relative to each other at that position, and the screw and positioning ring are positioned, thus enabling the corresponding protective plate or arc-shaped plate to rotate and be positioned relative to the fixed frame at that location.

[0013] Preferably, the two sides of the arc-shaped plate are respectively hinged to the corresponding protective plates. The protective plate is provided with a first guide block at the end away from the fixed frame, and the arc-shaped plate is provided with a second guide block at the end away from the fixed frame. The movable plate is slidably locked on the first guide block and the second guide block.

[0014] Preferably, the movable plate is rotatably fitted with a knob, one end of which is coaxially connected to a lead screw. A control ring is sleeved on the outside of the lead screw, and a handle is connected to the outside of the control ring. A slot is formed through the handle, and a sliding rod passes through the slot and slides with the handle. The control ring is actually a lead screw nut that cooperates with the lead screw. When the knob is rotated, the lead screw rotates accordingly, and the control ring that cooperates with the lead screw moves axially along the lead screw, causing the sliding rod to slide. The slot provides a limit for the sliding of the sliding rod.

[0015] Preferably, both ends of the handle are provided with end plates, and each end plate is slidably connected to a sliding plate. The inner side of the end plate is provided with a slider, and the outer side of the sliding plate is provided with a sliding groove. The slider and the sliding groove are slidably engaged. The top ends of the two sliding plates are connected by an elastic band, and a horizontal plate is connected between the bottom ends of the two sliding plates. The horizontal plate is connected to the handle by a telescopic pad.

[0016] Preferably, a positioning component is provided on the outer side of the protective plate. The positioning component includes a connecting plate, a insert plate, and a spring. The connecting plate is fixed on the protective plate. The side of the connecting plate near the first guide block is elastically connected to the insert plate through the spring. The other side of the insert plate is engaged with the moving plate.

[0017] The beneficial effect of this invention is that it provides a patient cooling and auxiliary nursing device for emergency internal medicine: (1) The heat preservation component can be set to keep the outside of the pipeline for transporting the infusion fluid warm. On the one hand, it reduces the contact time between the infusion fluid and the atmospheric environment during the infusion process. On the other hand, it increases the storage and folding function of the infusion pipeline to reduce the size of the device and facilitate the transport of the device with the patient. When using this device to keep the infusion fluid warm, connect the infusion bag of the infusion fluid to the metering pump and fix it to the outside of the annular sleeve. Then, wrap the infusion pipeline around the fixing clips spirally distributed on the outside of the annular sleeve so that the infusion pipeline is stored on the outside of the annular sleeve. Then, roll the heat preservation pad to the outside of the annular sleeve and then interlock the magnetic blocks set at both ends of the heat preservation pad to keep the infusion pipeline rolled on the outside of the annular sleeve warm.

[0018] (2) The protective components can protect the patient's hands and prevent the needle from falling off due to accidental collision or pulling of the infusion tubing during patient transport. When medical staff need to perform hand venous puncture on the patient, rotate the arc plate and another protective plate to keep the space above the fixed frame empty so that medical staff can perform puncture. After the puncture is completed, reset the screw so that the screw can reposition the protective plate and the arc plate.

[0019] (3) The positioning component can lock the position of the moving plate to help the patient maintain different hand postures. When the patient is puncturing, the handle is in the horizontal direction. At this time, the patient can directly hold the handle and keep the side to be punctured facing upward. When the device needs to be adapted to the hand size of different patients, turn the knob. The knob will drive the screw to rotate and then the control ring will drive the handle to slide along the slide bar to adapt to the hand size of different patients. Attached Figure Description

[0027] The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner. Therefore, they only show the components relevant to the invention, and the orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be limiting, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0028] like Figures 1 to 5 The illustrated device is an auxiliary nursing care device for cooling patients in the emergency internal medicine department, an embodiment of the present invention. It provides hand support and protection for patients during intravenous infusion, while effectively keeping the infusion tubing warm during the infusion process. In this embodiment, an infusion pump is used in conjunction with the infusion tubing, eliminating the need for a separate support to suspend the infusion bag.

[0029] like Figure 1 As shown, the cooling auxiliary nursing device includes an annular sleeve 11 and a heat-insulating component. The heat-insulating component includes a fixing frame 2 with a through hole 35. A clamping component is located near one end of the through hole 35 near the annular sleeve 11. Multiple fixing clips 12 are located on the outside of the annular sleeve 11, spirally distributed along the outside of the annular sleeve 11. After the infusion tubing of the injection pump is clamped by the clamping component, it is engaged with the fixing clips 12 and spirally positioned around the outside of the annular sleeve 11. A heat-insulating pad 20 is fitted on the outside of the positioning annular sleeve 11. The heat-insulating pad 20 has a planar state when unfolded and a suction state when wrapped around the annular sleeve 11. In the suction state, it wraps around the infusion tubing, providing heat insulation for the infusion tubing and effectively reducing heat exchange.

[0030] like Figure 2As shown, the insulation pad 20 is in the attracted state. After the insulation pad 20 is unfolded, a pair of magnetic blocks 19 are provided at both ends. A pull plate is provided on one side of the magnetic block 19. When the insulation pad 20 is rolled into a cylindrical shape, the two pairs of magnetic blocks 19 are attracted in an alternating manner.

[0031] like Figure 1 and Figure 5 As shown, the clamping assembly includes two paired clamping plates 38. Each clamping plate 38 has a sliding groove 40 at its lower edge, which slides into the fixed frame 2. A stop groove 39 is formed on the wall of the sliding groove 40. A connecting shaft 36 is provided between the two clamping plates 38, and two pull ropes 37 are connected to the outside of the connecting shaft 36. The free ends of the two pull ropes 37 are respectively connected to the top ends of the two clamping plates 38. The stop groove 39 is a groove added to the wall of the sliding groove 40 to increase friction and prevent the clamping plates 38 from slipping off the fixed frame 2.

[0032] like Figure 2 and Figure 3 As shown, a ring 13 is rotatably secured inside the annular sleeve 11. A pair of elastic pads 15 are symmetrically connected to the inner side of the ring 13. Each of the two elastic pads 15 is connected to a locking plate 14 at its opposite end. A movable plate 23 is connected to the outer side of the ring 13 via a slide rod 10.

[0033] like Figure 1 and Figure 2 As shown, elastic rings 1 are provided at both ends of the annular sleeve 11. A fan-shaped groove 9 is provided between the elastic ring 1 on the side closer to the fixed frame 2 and the annular sleeve 11. The slide rod 10 is slidably locked in the fan-shaped groove 9.

[0034] like Figure 1 , Figure 3 and Figure 5 As shown, a protective assembly is provided on one side of the fixed frame 2. The protective assembly includes three sets of corresponding fixed seats 34, positioning rings 31, and screws 33. The fixed seats 34 are respectively located on the edge of the fixed frame 2. Protective plates 25 are fixedly connected to the outer side of the positioning rings 31 at both ends, and an arc-shaped plate 3 is fixedly connected to the outer side of the positioning ring 31 in the middle. The screw 33 is rotatably engaged with the fixed seat 34. The inner wall of the positioning ring 31 has threads that engage with the screw 33. After the screw 33 passes through the fixed seat 34, its free end is screwed to the positioning ring 31. When the screw is screwed to the positioning ring, the screw and the fixed seat can rotate relative to each other at that position, and the screw and the positioning ring are positioned, thus forming the rotation and positioning operation of the corresponding protective plate or arc-shaped plate relative to the fixed frame at that position.

[0035] like Figures 1 to 3As shown, the two sides of the arc-shaped plate 3 are hinged to the corresponding protective plates 3. Specifically, the hinges are achieved through rotating rods 29 and connecting sleeves 21 sleeved at both ends of the rotating rods 29. Rotating rods 29 are rotatably mounted at both ends of the protective plates 3, and the connecting sleeves 21 are correspondingly fixed to the protective plates 3 on the corresponding sides. The two ends of the two rotating rods 29 are rotatably engaged with the connecting sleeves 21. A first guide block 22 is provided at the end of the protective plate 25 away from the fixed frame 2, and a second guide block 4 is provided at the end of the arc-shaped plate 3 away from the fixed frame 2. The moving plate 23 is slidably engaged with the first guide block 22 and the second guide block 4.

[0036] The protective components can protect the patient's hands and prevent the needle from falling off due to accidental collision or pulling of the infusion tubing during patient transport. When medical staff need to perform intravenous puncture on the patient's hand, they can first rotate the screw 33 fixedly connected in the middle and upper fixed seat 34 to disengage the screw 33 from the corresponding positioning ring 31. At this time, the arc plate 3 and the other protective plate 25 can be rotated along one end of the protective plate 25 that has not been disengaged, so that the space above the fixed frame 2 is left empty for medical staff to perform puncture. After the puncture is completed, the screw 33 is reset so that the screw 33 repositions the protective plate 25 and the arc plate 3.

[0037] like Figure 2 and Figure 3 As shown, a knob 24 is rotatably mounted on the movable plate 23. One end of the knob 24 is coaxially connected to a lead screw 26. A control ring 5 is sleeved on the outside of the lead screw 26, and a handle 17 is connected to the outside of the control ring 5. A slot is formed through the handle 17, and a sliding rod 10 passes through the slot and slides with the handle 17. The control ring is actually a lead screw nut that cooperates with the lead screw. When the knob is rotated, the lead screw rotates accordingly, and the control ring that cooperates with the lead screw moves axially along the lead screw, causing the sliding rod to slide. The slot provides a limit for the sliding of the sliding rod.

[0038] like Figure 2 As shown, both ends of the handle 17 are provided with end plates 16, and each end plate 16 is slidably connected to a sliding plate 7. A slider protrudes from the inner side of the end plate 16, and a groove 18 is provided on the outer side of the sliding plate 7, with the slider and groove 18 slidably engaged. The tops of the two sliding plates 7 are connected by an elastic band, and a horizontal plate 8 is provided at the bottom of the sliding plate 7. The horizontal plate 8 is connected to the handle 17 by a telescopic pad 6, which is a retractable and inflatable airbag. The upper end of the airbag is connected to the handle 17, and the lower end is connected to the horizontal plate 8. The distance between the handle 17 and the horizontal plate 8 is adjusted by the expansion and contraction of the airbag, thereby affecting the position of the upper elastic band. The volume of the airbag is controlled by a miniature air pump installed inside the handle 17.

[0039] like Figure 3 and Figure 4As shown, a positioning component is provided on the outer side of the protective plate 25. The positioning component includes a connecting plate 32, an insert plate 28 and a spring 30. The connecting plate 32 is fixed on the protective plate 25. The side of the connecting plate 32 near the first guide block 22 is elastically connected to the insert plate 28 through the spring 30. The other side of the insert plate 28 is engaged with the moving plate 23.

[0040] The positioning component can lock the position of the movable plate 23, helping the patient maintain different hand postures. When the patient is undergoing puncture, the handle 17 is in a horizontal position. At this time, the patient can directly grasp the handle 17 and keep the side to be punctured facing upwards. After the puncture is completed, first release the locking relationship between the insert plate 28 and the movable plate 23, and then slide the movable plate 23 along the first guide block 22 and the second guide block 4, so that the movable plate 23 moves synchronously with the handle 17 locked by the slide rod 10 until the handle 17 moves to the vertical position. At this time, the telescopic pad 6 is driven. As the telescopic pad 6 extends, it can move the horizontal plate 8 away from the handle 17. During the process of the horizontal plate 8 moving away from the handle 17, it will pull the elastic band connected to the top of the sliding plate 7, so that the elastic band works with the handle 17 to fix the patient's hand. After the moving plate 23 is completed, it can be fixed again by the insert plate 28. When the device needs to be adapted to the hand size of different patients, turn the knob 24. The knob 24 will drive the lead screw 26 to rotate, which will cause the control ring 5 to drive the handle 17 to slide along the slide bar 10 to adapt to the hand size of different patients.

[0041] During this process, the grip 17 can be in both horizontal and vertical positions. Figure 1 The handle 17 is in a horizontal position. This position corresponds to the patient's clenched fist during acupuncture, providing a grip for the patient. During gripping, the elastic band helps to stabilize the hand. After the infusion channel is established through acupuncture, the handle 17 can switch from a horizontal to a vertical position, which corresponds to the natural direction of the patient's palm, avoiding compression or interference between the handle and the patient's palm.

[0042] This heat-insulating component design can insulate the outside of the infusion tubing, reducing the contact time between the infusion fluid and the atmospheric environment during infusion. It also increases the folding and storage capabilities of the infusion tubing, reducing the device's size and facilitating transport with the patient. When using this device for infusion fluid insulation, the patient first inserts their arm into the annular sleeve 11 and places their hand on one side of the fixed frame 2. The patient's arm is then simply supported by the elastic rings 1 and support rings 13 at both ends of the annular sleeve 11, connected by a retaining plate 14 via an elastic pad 15. The puncture needle is then inserted from the side of the fixed frame 2 with the annular sleeve 11 to the other side. After completing the venous puncture, the needle is first inserted into the fixed frame 2 without the annular sleeve 11. One side of the infusion tubing is kept with sufficient length. Then, the connecting shaft 36 in the clamping assembly is rotated so that the connecting shaft 36 pulls the two pull ropes 37 at the same time. The two clamping plates 38 connected to the free ends of the two pull ropes 37 slide along the direction of the moving groove. After the two clamping plates 38 come closer to each other and clamp the pull ropes 37, the infusion bag of the infusion fluid is connected to the metering pump and fixed to the outside of the annular sleeve 11. Then, the infusion tubing is wound around the fixing clips 12 spirally distributed on the outside of the annular sleeve 11. After the infusion tubing is stored on the outside of the annular sleeve 11, the heat insulation pad 20 is rolled onto the outside of the annular sleeve 11. The magnetic blocks 19 set at both ends of the heat insulation pad 20 are staggered and attracted to each other to keep the infusion tubing rolled on the outside of the annular sleeve 11 warm.

[0043] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
