Description

Technical Field

[0001] The utility model relates to the field of medical technology, and more particularly to a device for assisting patients in transfusion. Background Art

[0002] Intravenous infusion therapy is a commonly used treatment method in clinical practice. During the infusion process, the infusion bottle is hung on the infusion pole. The existing infusion stands mainly include infusion seats and hanging brackets installed on the ceiling of the ward. When using the hanging bracket installed on the ceiling of the ward, since the bracket is set above the bed, the movable range is small, so the user can only complete the infusion in bed or at the bedside. Users who need more fluids need to stay in bed for a long time, which greatly limits their activities and is not conducive to the user's rehabilitation exercises or going to the toilet during the infusion process. Figure 1 As shown, Figure 1 The prior art provides an infusion chair with an infusion pole. The patient sits on the infusion chair for infusion, and the infusion bag needs to be hung on a leaf hook on the infusion pole. When the liquid is about to be infused, medical staff cannot be called in time.

[0003] Currently, many patients, due to various reasons, do not have family members to accompany them and need to go to the hospital for emergency infusion alone to treat physical discomfort. The use of the above-mentioned infusion chair and the suspension hanger installed on the ceiling of the ward will make it inconvenient for patients to go to the bathroom, or when the infusion is about to end, they cannot call medical staff in time to replace the liquid or remove the needle. At the same time, sitting on the infusion chair for a long time for infusion is not conducive to the comfort of the head, neck and trunk.

[0054] A backpack connector 121 is provided on the side of the backpack fixing part 12 close to the patient, and an upper limb rear connector 712 is provided on the side of the upper limb placement pillow 71 away from the patient. The backpack connector 121 and the upper limb rear connector 712 are detachably connected. The above scheme is adopted, and the detachable connection between the backpack connector 121 and the upper limb rear connector 712 is conducive to the regularization of the upper limb placement pillow 71. When in use, the backpack fixing part 12 and the upper limb placement pillow 71 are in a separated state to facilitate the placement of the patient's forearm and hand; when not in use, the upper limb placement pillow 71 can be directly adhered to the backpack fixing part 12, which is conducive to the arrangement of the upper limb placement pillow 71.

[0055] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a weight sensor 8 is provided on the side of the telescopic rod 31 close to the infusion hook 4. The weight sensor 8 can be located at the top of the telescopic rod 31 away from the fixing part 32. The sensing end of the weight sensor 8 is connected to the infusion hook 4. The type of the weight sensor 8 can be determined according to specific needs and is not specifically limited here. A controller 9 and a battery 120 are provided on the backpack fixing portion 12. The controller 9 is used to receive and process the sensing signal of the gravity sensor. The controller 9 is provided with a vibration signal to the vibrator 110 when the weight of the infusion bag on the infusion hook 4 is less than a preset value, so as to remind the patient that the liquid in the infusion bag needs to be changed or the needle is removed. If the preset value is lower than 20ml, a vibration signal will be generated to the vibrator 110. The vibration of the vibrator 110 can remind the patient that the liquid in the infusion bag is about to be finished and the liquid needs to be replaced or the needle needs to be removed in time. For patients with normal heart function, 60 drops of liquid are used as an example per minute. 60 drops of liquid are 3ml, which can be understood as reminding the patient between 5 and 7 minutes. Of course, the preset value can also be other values, such as 10ml, 15ml, 25ml, which can be limited according to specific circumstances. This embodiment does not make specific It is defined that a vibrator 110 is provided on the backpack main body 11, and the vibrator 110 is provided between the positioning plate 113 and the filler 112. The weight sensor 8 and the vibrator 110 are electrically connected to the controller 9 respectively. The weight sensor 8 detects the weight of the infusion bag on the infusion hook 4. When the weight of the infusion bag on the infusion hook 4 is lower than the preset value, the sensing information is transmitted to the controller 9. After receiving the sensing information, the controller 9 processes the information and then sends an electrical signal to the vibrator 110. The vibrator 110 starts to work to remind the patient that the remaining liquid in the infusion bag on the infusion hook 4 is low, so that the patient stays awake and asks medical staff to replace the liquid or remove the needle in time. The controller 9 is electrically connected to the battery 120. The battery 120 provides power for the controller 9, the vibrator 110 and the weight sensor 8. The controller 9 can be an STM32 chip with ARM Cortex-M3 as the core. The vibration frequency range of the vibrator 110 is 4Hz-8Hz.

[0056] During specific use, after the medical staff has given an injection, the patient sits on the infusion chair with the backpack body 1 on his back. Since the telescopic part 3 is located at the backpack fixing part 12 on at least one side of the backpack main body 11, the patient's infusion will not be affected when leaning on the back of the infusion chair, thereby improving the patient's comfort; through the mutual cooperation between the headrest 5 and the lumbar pillow 6, the patient's brain occipital is resting in the headrest groove 510 of the headrest 5, and the lumbar spine can rest on the lumbar pillow 6, further improving the patient's comfort; through the upper limb fixing device 7, the patient's upper limbs can be placed on the upper limb placement pillow 71, improving the comfort of the patient's forearm and hand; through the mutual cooperation between the weight sensor 8, controller 9, vibrator 110 and battery 120, the patient can be reminded that the remaining liquid in the infusion bag on the infusion hook is low, so that the patient can stay awake and remind the medical staff to change the liquid or remove the needle in time; since the overall solution does not restrict the patient's free movement, the patient can go to the emergency pharmacy to get medicine, and it is also convenient for the patient to go to the bathroom alone.

[0057] It should be noted that: since the patient goes to the hospital for infusion alone, if the medical staff prescribes a prescription temporarily, the patient can carry the infusion backpack alone and go to the pharmacy to pick up the medicine while receiving the infusion. There is no need to wait until the infusion is completed before going to the pharmacy door to pick up the medicine, which greatly saves time. When there are many people queuing at the pharmacy, through the mutual cooperation between the backpack body 1, the telescopic rod 31, the headrest 5, the lumbar pillow 6 and the upper limb fixing device 7, the patient can sit directly on the chair in front of the pharmacy while receiving the infusion and waiting to pick up the medicine, thereby reducing the patient's physical exertion as much as possible.
