[0032] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0033] like Figure 1-Figure 5 As shown, the present invention provides an infusion heat preservation nursing control device, including a base 10, a vertical plate 11, a syringe 12 and a controller, the vertical plate 11 is fixedly mounted on the base 10 along the longitudinal direction, and the syringe 12 has a syringe, a push rod, a handle and a needle. The above contents are all prior art, and the specific structure is not repeated here. The device also includes a rotating disk 20, a first motor 21, a fixing plate 30, a heating pad 31, a temperature sensor 32 and a driving assembly 40.

[0034] The rotating disk 20 is disposed in the longitudinal direction and is rotatably connected to the vertical plate 11. The first motor 21 is fixedly mounted on the vertical plate 11 and is electrically connected to the controller. The first motor 21 is used to control the rotating disk 20 to rotate.

[0035] The fixing plate 30 is fixedly mounted on the rotating disk 20, and a limiting space 33 extending inward and adapted to the syringe 12 is opened on the front side of the fixing plate 30. A first screw 34 is arranged on the fixing plate 30, and the threaded end of the first screw 34 can pass through the fixing plate 30 and contact the handle of the syringe 12, thereby fixing the syringe 12 in the limiting space 33.

[0036] The heating pad 31 is fixedly mounted on the inner wall of the limiting space 33. The temperature sensor 32 is in contact with the syringe of the syringe 12, and both the temperature sensor 32 and the heating pad 31 are electrically connected to the controller.

[0037] The drive assembly 40 is used to control the movement of the push rod of the syringe 12 .

[0038] Before using the device, medical personnel draw liquid medicine into the syringe through the syringe 12 , and then put the syringe 12 into the limiting space 33 and fix it with the first screw 34 .

[0039] The specific working process of this device is:

[0040] The first step is to heat the liquid medicine. The controller controls the heating pad 31 to start, and the heating pad 31 will heat the liquid medicine in the syringe. When the temperature sensor 32 detects that the temperature of the syringe exceeds the preset range value, the controller controls the heating pad 31 to stop heating, thereby preventing the temperature of the liquid medicine from being too high, and the heating process is safer. When the temperature sensor 32 detects that the temperature of the syringe is lower than the preset range value, the controller controls the heating pad 31 to continue heating, so that the liquid medicine is always in the appropriate temperature range.

[0041] The second step is to adjust the position of the syringe 12. The controller controls the first motor 21 to start, and the first motor 21 controls the rotating disk 20 to rotate until the needle of the syringe 12 is vertically upward, at which time the air in the syringe 12 moves to the top of the syringe barrel of the syringe 12 in the form of bubbles.

[0042] The third step is to discharge the air in the syringe. The drive assembly 40 is started to push the push rod upward until the liquid medicine flows out from the needle of the syringe 12. At this time, the air in the syringe has been completely discharged, and then the needle of the syringe 12 is inserted into the infusion tube 80.

[0043] The fourth step is to exhaust the air in the infusion tube 80. The driving assembly 40 continues to work, pushing the push rod of the syringe 12 upward at a constant speed until the infusion needle 81 on the infusion tube 80 has liquid flowing out, at which time the air in the infusion tube 80 has been completely exhausted, and then the infusion needle 81 can be inserted into the patient's body.

[0044] Step 5: Infusion. The drive assembly 40 continues to work, pushing the push rod of the syringe 12 upward at a uniform speed, so that the patient can be infused at a uniform speed.

[0045] The entire working process of the device prevents the air in the syringe 12 and the infusion tube 80 from entering the patient's body, thereby ensuring the safety of infusion and also improving the stability of the infusion speed.

[0046] The traditional operation is that the medical staff points the needle of the syringe 12 upwards and presses the push rod by hand to exhaust the air. However, the accuracy of manual operation is poor, and the syringe 12 will shake during the process of pressing the push rod. It cannot ensure that the needle of the syringe 12 is always completely vertically upward. As a result, when the push rod moves upward, some air may still not be exhausted in the syringe 12, posing a safety hazard.

[0047] The device can ensure that the needle of the syringe 12 is always completely vertically upward without shaking during the exhaust process of the third and fourth steps through automatic operation, and the exhaust effect is better.

[0048] In one embodiment, the driving assembly 40 includes a guide rail 41 , a slider 42 , a lead screw 43 and a second motor 44 .

[0049] The guide rail 41 is fixedly mounted on the rotating disk 20. The slider 42 is disposed on the guide rail 41 and is slidably connected to the guide rail 41. The lead screw 43 passes through the slider 42 and is threadedly connected to the slider 42, and both ends of the lead screw 43 are rotatably connected to the rotating disk 20. The second motor 44 is fixedly mounted on the rotating disk 20 and is electrically connected to the controller, and the second motor 44 is used to control the rotation of the lead screw 43.

[0050] When the driving assembly 40 is started, the controller controls the second motor 44 to start, and the second motor 44 drives the lead screw 43 to rotate. Under the action of the guide rail 41, the slider 42 will approach the syringe 12 and push the push rod upward at a uniform speed.

[0051] When the controller controls the second motor 44 to cut off power, the driving assembly 40 will stop working.

[0052] The driving assembly 40 has a simple structure and is easy to operate and control.

[0053] In one embodiment, it further includes a rotating assembly 50 , a telescopic assembly 60 and a catheter 70 .

[0054] The rotating assembly 50 includes a rotating ring 51, a gear ring 52, a third motor 53 and a gear 54. The rotating ring 51 is disposed longitudinally outside the rotating disk 20 and is rotatably connected to the vertical plate 11. The axis of the rotating ring 51 is colinear with the axis of the rotating disk 20. The gear ring 52 is fixedly mounted on the rotating ring 51. The third motor 53 is fixedly mounted on the vertical plate 11 and is electrically connected to the controller. The gear 54 is fixedly mounted on the output shaft of the third motor 53 and is meshed with the gear ring 52.

[0055] The telescopic assembly 60 includes a fixed block 61, a guide rod 62, an electromagnet 63, a permanent magnet 64 and a second screw 67. The fixed block 61 is fixedly mounted on the rotating ring 51, and a slot is provided on the fixed block 61. The guide rod 62 passes through the fixed block 61 and is slidably connected to the fixed block 61, and a movable block 65 and a stopper 66 are fixedly mounted on the inner end surface and the outer end surface of the guide rod 62, respectively. The electromagnet 63 is arranged opposite to the permanent magnet 64, and the electromagnet 63 is fixedly mounted on the fixed block 61 and is electrically connected to the controller, and the permanent magnet 64 is fixedly mounted on the movable block 65. The second screw 67 is arranged on the fixed block 61.

[0056] The conduit 70 is disposed on the first side of the rotating disk 20. A first plug plate 71 is provided on the first end of the conduit 70, and the first plug plate 71 is adapted to the slot, and the threaded end of the second screw 67 passes through the fixing block 61 and contacts the first plug plate 71, and the second end of the conduit 70 is a free end.

[0057] In the initial state, the electromagnet 63 is in a powered state, the permanent magnet 64 and the electromagnet 63 are attracted together, and the first end of the conduit 70 is fixed to the fixing block 61 by the second screw 67 .

[0058] In the third step, when the liquid medicine flows out from the needle of the syringe 12, the controller controls the third motor 53 to start, and the third motor 53 drives the rotating ring 51 to rotate until the first end of the catheter 70 moves to the top of the needle of the syringe 12. At this time, the controller changes the current direction of the electromagnet 63, and the electromagnet 63 and the permanent magnet 64 repel each other, and the first end of the catheter 70 will be plugged into the needle of the syringe 12. Then the drive assembly 40 is started, and the push rod of the syringe 12 is pushed upward at a uniform speed until the liquid medicine flows out from the second end of the catheter 70, and the air in the syringe has been completely discharged.

[0059] Then, the controller controls the first motor 21 and the third motor 53 to start synchronously, and the rotating disk 20 and the rotating ring 51 rotate synchronously until the first end of the catheter 70 is lower than the needle of the syringe 12. At this time, the controller changes the current direction of the electromagnet 63 again, and the electromagnet 63 and the permanent magnet 64 attract each other, and the first end of the catheter 70 will be separated from the needle of the syringe 12. Since the first end of the catheter 70 is lower than the needle of the syringe 12 at this time, no liquid medicine will leak out when it is separated. After the separation is completed, the controller controls the first motor 21 and the third motor 53 to start synchronously, and the rotating disk 20 and the rotating ring 51 rotate synchronously to reset until the needle of the syringe 12 is vertically upward, and then the needle of the syringe 12 is inserted into the infusion tube 80.

[0060] The coordinated use of the telescopic assembly 60 and the catheter 70 can guide out all the liquid medicine flowing out of the needle of the syringe 12 in the third step, preventing the liquid medicine from spilling onto the surface of the device, thereby protecting the cleanliness of the operating room environment.

[0061] In one embodiment, the first cup body 14 and the first liquid level sensor are further included. The first cup body 14 is placed on the base 10. The first liquid level sensor is fixedly mounted on the inner wall of the first cup body 14 and is electrically connected to the controller. The second end of the conduit 70 is located directly above the first cup body 14.

[0062] After the medicine flows out from the second end of the catheter 70, it will fall into the first cup body 14. When the first liquid level sensor detects that the liquid level has risen, it sends a signal to the controller. On the one hand, the controller controls the second motor 44 to stop working to prevent the medicine in the syringe from continuing to flow out; on the other hand, the controller changes the current direction of the electromagnet 63 again, the electromagnet 63 and the permanent magnet 64 attract each other, and the second end of the catheter 70 will be separated from the needle of the syringe 12.

[0063] The design of the telescopic assembly 60, the catheter 70, the first cup body 14 and the first liquid level sensor enables the air in the syringe to be automatically discharged in the third step. The entire process does not require any human intervention or observation, and is more convenient to use.

[0064] In one embodiment, there are two telescopic assemblies 60 , and the two telescopic assemblies 60 are arranged on the rotating ring 51 at intervals along the circumferential direction.

[0065] An infusion tube 80 is arranged on the second side of the rotating disk 20, and the infusion tube 80 and the catheter 70 are arranged one-to-one with the two telescopic components 60. A second plug plate 82 is arranged on the first end of the infusion tube 80, and the second plug plate 82 is adapted to the slot. The threaded end of the second screw 67 passes through the fixing block 61 and contacts the second plug plate 82. An infusion needle 81 is fixedly installed on the second end of the infusion tube 80.

[0066] In the initial state, the electromagnet 63 is in a powered state, the permanent magnet 64 is attracted to the electromagnet 63 , and the first end of the infusion tube 80 is fixed to the fixing block 61 by the second screw 67 .

[0067] In the fourth step, the controller controls the third motor 53 to start, and the third motor 53 drives the rotating ring 51 to rotate until the first end of the infusion tube 80 moves to the top of the needle of the syringe 12. At this time, the controller changes the current direction of the electromagnet 63, and the electromagnet 63 and the permanent magnet 64 repel each other, and the first end of the infusion tube 80 will be plugged into the needle of the syringe 12. Then the drive assembly 40 is started, and the push rod of the syringe 12 is pushed upward at a uniform speed until the liquid medicine flows out from the second end of the infusion tube 80. At this time, the air in the infusion tube 80 has been completely discharged, and the infusion needle 81 can be inserted into the patient's body.

[0068] The coordinated use of the telescopic assembly 60 and the infusion tube 80 can realize the automatic insertion of the infusion tube 80 and the needle of the syringe 12 without manual intervention, making the operation of the device more convenient.

[0069] In one embodiment, the second cup body 15, the second liquid level sensor and the buzzer 16 are further included. The second cup body 15 is placed on the base 10. The second liquid level sensor is fixedly mounted on the inner wall of the second cup body 15 and is electrically connected to the controller. The second end of the conduit 70 is located directly above the second cup body 15. The buzzer 16 is fixedly mounted on the base 10 and is electrically connected to the controller.

[0070] After the medicine flows out of the infusion needle 81, it will fall into the second cup body 15. When the second liquid level sensor detects that the liquid level has risen, it sends a signal to the controller. On the one hand, the controller controls the second motor 44 to stop working to prevent the medicine from continuing to flow out; on the other hand, the controller controls the buzzer 16 to start, and the buzzer 16 makes a sound to remind the medical staff to pay attention. The medical staff can then insert the infusion needle 81 into the patient's body.

[0071] The design of the telescopic component 60, the infusion tube 80, the second cup body 15 and the second liquid level sensor enables the air in the infusion tube 80 to be automatically discharged in the fourth step. The entire process does not require any human intervention or observation, and is more convenient to use.

[0072] In one embodiment, a plurality of fasteners 13 are fixedly mounted on the vertical plate 11 , and the fasteners 13 are used to clamp the catheter 70 and / or the infusion tube 80 , so that the catheter 70 and the infusion tube 80 are arranged in an orderly manner and not in a disorderly manner.

[0073] In one embodiment, the base 10 is provided with a first limiting hole and a second limiting hole adapted to the first cup body 14 and the second cup body 15 , respectively, so as to prevent the first cup body 14 and the second cup body 15 from shaking.

[0074] In the present device, heating and heat preservation, exhausting the air in the syringe and exhausting the air in the infusion tube 80 are all performed automatically without manual intervention, which can greatly reduce the operation of medical staff.

[0075] When in use, medical staff only need to put the syringe 12 into the limiting space 33 and fix it, and then insert the infusion needle 81 into the patient's body when the buzzer 16 sounds. No other operations are required, and it is easy to use.

[0076] It is worth noting that in order to ensure patient safety, after each use of the device, medical staff need to loosen the first screw 34, the second screw 67 and the second screw 67 to replace the new syringe 12, catheter 70 and infusion tube 80.
