Description

Technical Field

[0001] The present invention relates to the technical field of infusion equipment, and more particularly to an automatic alignment device for an infusion bottle opening based on multiple weighing sensors. Background Art

[0002] At present, in order to obtain infusion information, many domestic infusion treatments use weighing infusion, that is, a weighing device is hung on the infusion bag to measure the weight of the infusion bag in real time, and the remaining residual capacity and remaining infusion time of the infusion process are calculated through an algorithm. When the infusion is completed, the weighing sensor returns to zero and an alarm is sounded to notify the nurse to change the bottle or remove the needle.

[0003] However, during the infusion treatment process, the capacity of the infusion bag saline varies, such as 50ml, 100ml, 200ml, 250ml, 500ml, 1000ml, etc., and the lengths of the corresponding infusion bags are different. The larger the capacity of the infusion bag, the longer the infusion bag. There is a certain proportional relationship between the size, length and capacity of the infusion bag.

[0004] When using a single-puncture disposable infusion set (single head), the nurse can manually adjust the upper infusion rod part of the infusion stand to adjust the height of the infusion bag so that the infusion bottle mouth is basically at a uniform height for infusion, which increases the manual operation process; when using a multi-puncture infusion set (multi-branch), since the infusion tubes of each branch of the multi-branch infusion set are the same length, the bottle mouths of each infusion bag need to be at a uniform height to easily insert the plugs of the infusion tubes of each branch into the bottle mouths of the infusion bag. If the bottle mouth heights are different, the infusion tubes of some branches will be folded or not long enough, so there is still room for improvement. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an automatic alignment device for the mouth of an infusion bottle based on multiple weighing sensors, which has the advantage of being able to automatically adjust the height of the mouth of the infusion bag to make the height of the mouth of each infusion bag consistent.

[0024] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0025] The present invention provides an automatic alignment device for an infusion bottle opening based on multiple weighing sensors, such as Figure 1-3As shown, it includes: an infusion stand 1, a rack housing 2, several weighing modules 3, several bottle hanging assemblies 4 corresponding one to one with the several weighing modules 3, several bottle mouth adjustment assemblies 5 corresponding one to one with the several bottle hanging assemblies 4, and a control assembly 6; the rack housing 2 is arranged on the infusion stand 1; several weighing modules 3 are all arranged in the rack housing 2; several bottle mouth adjustment assemblies 5 are arranged one to one on several weighing modules 3; several bottle hanging assemblies 4 are arranged one to one on several bottle mouth adjustment assemblies 5; the control assembly 6 is arranged in the rack housing 2; several weighing modules 3 and several bottle mouth adjustment assemblies 5 are electrically connected to the control assembly 6. In actual application, by placing the bottle mouth adjustment component 5 on the corresponding weighing module 3 and the bottle hanging component 4 on the corresponding bottle mouth adjustment component 5, the weight recognized by the weighing module 3 is reset to zero, and then the infusion bag is hung on the bottle hanging component 4. The weighing module 3 can identify the weight of the infusion bag, calculate the capacity of the infusion bag according to the existing algorithm, and control the bottle mouth adjustment component 5 to adjust the bottle hanging component 4 according to the capacity of the infusion bag, so that the bottle hanging component 4 moves up and down, thereby making the bottle mouths of all the infusion bags on the bottle hanging component 4 at the same height, thereby achieving automatic adjustment of the height of the bottle mouths of the infusion bags to make the bottle mouths of each infusion bag consistent, avoiding the situation where some branched infusion tubes are folded or bent or not long enough. Among them, the weighing module 3 is a weighing sensor.

[0026] Furthermore, the bottle mouth adjustment assembly 5 includes: an adjustment motor 51, a drive gear 52, and a driven rack 53; the adjustment motor 51 is disposed on the weighing module 3; the drive gear 52 is disposed on the output shaft of the adjustment motor 51; a guide groove 7 corresponding to and adapted to the driven rack 53 is disposed on the frame housing 2; the driven rack 53 is slidably disposed within the guide groove 7; the bottle hanging assembly 4 is disposed at the lower end of the driven rack 53; and the driven rack 53 is meshed with the drive gear 52. In actual application, the drive gear 52 is driven to rotate by the adjustment motor 51. Since the drive gear 52 meshes with the driven rack 53, the driven rack 53 moves up and down along the guide groove 7 under the action of the drive gear 52, thereby driving the bottle hanging assembly 4 on the driven rack 53 to move up and down, thereby adjusting the bottle mouth position of the infusion bag.

[0027] Optionally, the regulating motor 51 is a reduction motor. In practical applications, the reduction motor has a static torque and a high reduction ratio to keep the infusion bag at a certain height.

[0028] Optionally, the control assembly 6 includes a PCB 61 and a battery 62; the battery 62 is electrically connected to the PCB 61; and the PCB 61 is electrically connected to the plurality of weighing modules 3 and the plurality of bottle-mouth adjustment assemblies 5. In actual use, the battery 62 powers the PCB 61, the adjustment motor 51, and the weighing modules 3. The PCB 61 determines the corresponding length of the infusion bag based on the weight measured by the weighing modules 3, controls the rotation of the adjustment motor 51, drives the gear 52 to move the driven rack 53, and moves the bottle-hanging assembly 4 up and down, thereby adjusting the position of the bottle-mouth of the infusion bag.

[0029] Furthermore, it includes a positioning assembly 8, which is disposed at the top of the guide slot 7 and is electrically connected to the control assembly 6. In actual use, after the infusion is completed, the infusion bag on each hanging bottle assembly 4 is removed. At this time, the weight measured by each weighing module 3 is zero. The PCB board 61 controls each adjustment motor 51 to drive the driving gear 52 to rotate, thereby controlling the downward movement of the driven rack 53. The driven rack 53 is monitored by the positioning assembly 8. When the driven rack 53 returns to its initial position, the positioning assembly 8 sends an electrical signal to the PCB board 61, which controls the adjustment motor 51 to stop and maintain this position, and defaults this position to the motor's initial zero position.

[0030] Furthermore, the positioning assembly 8 includes a photoelectric switch transmitting end 81 and a photoelectric switch receiving end 82. The photoelectric switch transmitting end 81 is disposed at the top of the guide slot 7 and on one side of the guide slot 7. The photoelectric switch receiving end 82 is disposed at the top of the guide slot 7 and on the other side of the guide slot 7. Both the photoelectric switch transmitting end and the photoelectric switch receiving end 82 are electrically connected to the control assembly 6. In actual use, when light emitted by the photoelectric switch transmitting end 81 is received by the photoelectric switch receiving end 82, an electrical signal is sent to the PCB board 61, which controls the adjustment motor 51 to stop operation.

[0031] Furthermore, a liquid crystal display screen 9 is provided on the frame housing 2; the liquid crystal display screen 9 is electrically connected to the control assembly 6. In actual application, by providing the liquid crystal display screen 9, the capacity and remaining capacity of the infusion bag on each hanging bottle assembly 4 can be displayed, which can facilitate the patient to check the infusion progress.

[0032] Furthermore, the bottle hanging assembly 4 includes a hook, the upper end of which is fixed to the bottle mouth adjustment assembly 5. In actual application, the hook can be matched with the corresponding hole on the infusion bag to achieve the hanging of the infusion bag.

[0033] Furthermore, the housing 2 is provided with a plurality of fine-tuning button groups 10 corresponding one to each of the bottle-mouth adjustment components 5; each of the fine-tuning button groups 10 is electrically connected to the control component 6. In actual use, if fine-tuning of the position of a bottle-hanging component 4 is required, the position of the bottle-hanging component 4 can be set using the fine-tuning button group 10 corresponding to the bottle-hanging component 4. After manual setting, the PCB board 61 records the current position information and stores it in correspondence with the capacity of the infusion bag mounted on the bottle-hanging component 4.

[0034] Furthermore, the fine-adjustment button assembly 10 includes a set switch 101, an up button 102, and a down button 103. Each of the set switch 101, up button 102, and down button 103 is disposed on the housing 2 and located at the corresponding location of the bottle mouth adjustment assembly 5. The set switch 101, up button 102, and down button 103 are electrically connected to the control assembly 6. In practice, the up button 102 and down button 103 can be used to fine-tune the hook height. After all settings are completed, turning off the set switch 101 maintains the current set position of the adjustment motor 51, and this height position is memorized in the program chip stored on the PCB 61. The next time an infusion bag of the same capacity is placed, the height is adjusted according to the newly set hook position information.

[0035] During the specific implementation process, it is assumed that this device adopts three workstations, which can hang three infusion bags, and uses a three-branch disposable infusion set for intelligent weighing infusion. The first workstation on the left is defined as the first hook, the middle workstation is defined as the second hook, and the right workstation is defined as the third hook.

[0036] Place a 50ml infusion bag on the first hook and turn on the setting switch 101 of the first station. The LCD screen will display that the capacity of the infusion bag is 50ml. At this time, the weighing module 3 senses and determines the capacity value of the infusion, and starts the adjusting motor 51 through the program control of the PCB board 61. The adjusting motor 51 rotates and lifts the hook to the h1 position according to the internal setting height. According to the schematic diagram, place the 100ml infusion bag on the third hook and the 200ml infusion bag on the second hook. The corresponding weighing module 3 senses and determines the capacity value of the infusion bag, and the corresponding adjusting motor 51 lifts the corresponding hook to the h2 or h3 position according to the weight value of the infusion bag.

[0037] If fine-tuning is required, the up or down button 103 is pressed. After the setting is completed, the setting switch 101 is closed, and the PCB board 61 records the position information at this time.

[0038] When the infusion is completed and each infusion bag is taken away, the weighing information of the three sensors is zero, and the setting switch 101 is pressed, and the circuit board program sends an instruction to the motor, and the three hooks move downward. When they move downward to the positioning component 8, the photoelectric switch transmitting end 81 is connected to the photoelectric switch receiving end 82, which triggers the zero position stop program of the adjustment motor 51, and the adjustment motor 51 stops running and remains in this position, and defaults to the initial zero position of the motor.

[0039] The specific infusion bag capacity and the corresponding height required for lifting can be referred to the following table:
