Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that equivalent changes or substitutions in function, method or structure according to the embodiments are included in the scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, mechanically or electrically connected, or interconnected between two elements, directly or indirectly through intervening media, and the specific meaning of the terms may be understood by those skilled in the art according to their specific situation.
As shown in fig. 1, 2 and 3, the present invention provides an applicator pump for infusion, comprising: base 1, upper cover 2, medicine storage device 3, control circuit board 4 and drive assembly 5, base 1's top upwards extends mount pad 11, medicine storage device 3 can be dismantled and place in mount pad 11, drive assembly 5 is connected medicine storage device 3, control circuit board 4 installs on base 1, control circuit board 4's on-off 6 sets up in the one side that is close to medicine storage device 3, control circuit board 4 connects and controls drive assembly 5 operation, 2 lids of upper cover close on base 1 and cover control circuit board 4 and drive assembly 5's top. The switch-on switch 6 is arranged in the re-placing cavity 111, and the control circuit board 4 drives the motor 51 to work by pressing the switch-on switch 6 when the medicine storage device 3 is installed, so that the control circuit can be switched on and operated as soon as the medicine storage device 3 is installed.
As shown in fig. 4, the mounting base 11 includes a placing cavity 111, a guide rail 112 and a notch 113, the inner wall of the placing cavity 111 is provided with at least one guide rail 112, and the notch 113 is communicated with the placing cavity 111. The cavity 111 installation medicine storage device 3 is placed in the utilization, and breach 113 is established in the one end of placing cavity 111 bottom and being close to drive assembly 5 usually to accomplish the pressfitting to the switch when installing medicine storage device 3 again and accomplishing soon, switch-on switch 6 intercommunication control circuit during.
Switch-on switch 6 is protruding in one side that control circuit board 4 is close to medicine storage device 3, and switch-on switch 6 installs in breach 113 and extends into and places chamber 111, and switch-on switch 6 interferes with medicine storage device 3's installation line mutually, and then switch-on circuit control drive assembly 5 operation is switched on to medicine storage device 3 pressfitting switch-on switch 6. The switch-on switch 6 extends into the placing cavity 111 from the gap 113, and the switch-on switch 6 is pressed to realize that the control circuit board 4 drives the motor 51 to work when the medicine storage device 3 is installed, so that the control circuit can be switched on to operate as soon as the medicine storage device 3 is installed. Switch-on switch 6 forms less contained angle in the inner wall of placing chamber 111, and pressfitting switch-on switch 6 gradually when medicine storage device 3 inserts from the top of placing chamber 111 like this makes switch-on switch 6 intercommunication control circuit, if switch-on switch 6 and the contained angle of placing the inner wall of chamber 111 too big can lead to switch-on switch 6 to block medicine storage device 3 and remove and can not reach the purpose of opening the switch.
Of course, the on switch 6 is not limited to an electronic component that can open the circuit, interrupt the current, or flow the current to other circuits, and may include other modes that can operate or stop the driving motor 51 of the control circuit board 4. For example, the on-switch 6 may also be a sensor, and when the sensor detects the medicine reservoir, a signal is fed back to the control circuit board 4, and the control circuit board 4 drives the motor 51 to operate or stop, which of course requires the battery to supply power to the control circuit board 4 and the on-switch 6 all the time.
One side of keeping away from mount pad 11 on base 1 is equipped with support 12, and support 12 is equipped with two, and control circuit board 4 installs on support 12. The support 12 facilitates the installation of the control circuit board 4, and for more convenient production, the support 12 and the mounting seat 11 are integrally formed with the base 1.
The guide rails 112 are preferably provided in two, symmetrically disposed on the inner wall of the placing chamber 111, and the moving position of the push rod 53 is easily defined by the guide rails 112.
As shown in fig. 5, the driving assembly 5 includes: the motor 51, the screw rod 52, the push rod 53, the battery 54 and the fixed shell 55, the battery 54 and the motor 51 are both arranged in the fixed shell 55, the output end of the motor 51 is connected with the screw rod 52, and the push rod 53 is sleeved on the outer side of the screw rod 52. The battery 54 is used for supplying power to the motor 51 and the control circuit board 4, the motor 51 drives the screw 52 to rotate, the push rod 53 is matched with the screw 52, the screw 52 rotates under the driving of the motor 51, and the push rod 53 moves along the guide rail 112, so that the infusion of the liquid medicine in the medicine storage device 3 is realized.
The battery 54 is connected with the control circuit board 4 and the motor 51 and supplies power to the control circuit board 4 and the motor 51, the control circuit board 4 is connected with the motor 51, and the control circuit board 4 drives the motor 51 to run or stop. The infusion parameters are set in the control circuit board 4, and the control circuit board 4 only needs to drive the motor 51 to infuse according to the specified parameters.
The push rod 53 is provided with a mounting hole 56, the mounting hole 56 is provided with internal threads, the screw 52 is matched with the internal threads in the mounting hole 56, the motor 51 drives the screw 52 to rotate, and the screw 52 drives the push rod 53 to move on the guide rail 112. The motor 51 drives the screw 52 to rotate, the push rod 53 is matched with the screw 52, the screw 52 rotates under the driving of the motor 51, and the push rod 53 moves along the guide rail 112, so that the infusion of the liquid medicine in the medicine storage device 3 is realized.
At least one guide groove 57 is formed in the outer side of the push rod 53, the guide grooves 57 are sleeved on the guide rails 112, 2 guide grooves 57 are formed in the number which is consistent with the number of the guide rails 112, and the movement position of the push rod 53 is limited by the matching of the guide grooves 57 and the guide rails 112.
The motor 51 is a dc motor or a stepping motor. Insulin infusion requires a minimum infusion of 0.001ml (i.e., 0.1U) per hour and is divided equally per hour, a very delicate infusion requirement. There is a concept that needs to be first defined: the motor 51 cannot meet the infusion precision and safety requirements of the infusion pump, and an infusion mechanism consisting of the motor 51, a reducer, an encoder, a push plate and the like is required to be matched with bottom firmware, an algorithm and the like to form a complete system for ensuring. Assuming that the inner diameter is 12mm, the screw pitch is 0.5mm, and the reduction ratio is 700: 1, combining positive and negative deviation, motor 51 resolution and other factors, the control precision can reach 2%, if the reduction ratio is changed to 500: 1, then the accuracy is 3.3%, while the encoder needs to employ a photoelectric encoder. The precision of the infusion dosage is ensured by the measures.
The foregoing describes only some embodiments of the present invention and modifications and variations thereof will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
