Currently, infusion pumps can be stacked from pump to pump, but cascade infusion (or relay infusion) cannot be achieved after stacking. When the pumps are stacked, the infusion workstation is needed to convey the working conditions of two adjacent infusion pumps, such as the information of the infused medicines, whether the infusion is completed and the like, so that the online purpose is achieved.
The infusion pump depends on the infusion workstation to communicate, and after the infusion pump is separated from the infusion workstation, the pump and the pump cannot be directly communicated, namely, the infusion pump cannot be directly superposed to work on line after being separated from the infusion workstation. The matched infusion workstation not only consumes a large amount of cost, but also occupies a large space in a limited clinical space environment, and brings inconvenience to clinical application.
Referring to fig. 1 to 9, the present invention provides an infusion pump, which includes a pump body 100 and an infrared sensor assembly mounted on the pump body 100 for emitting and receiving infrared light signals; when the infrared sensor assemblies of the infusion pumps are arranged oppositely step by step, the infusion pump coding infusion information of the upper stage is sent to the infrared sensor assembly of the upper stage, the infrared sensor assembly of the upper stage emits the infrared light signal according to the infusion information, the infrared sensor assembly of the infusion pump of the lower stage receives the infrared light signal, and the infusion pump of the lower stage decodes the infrared light signal to obtain the infusion information and works according to the infusion information.
Specifically, the infrared sensor assemblies can be installed at a plurality of positions of the pump body 100, can be installed along the vertical direction of the pump body 100, can also be installed along the left and right directions of the pump body 100, or installed along the front and rear directions of the pump body 100, and only the infrared sensor assemblies need to be arranged relatively, so that the infrared sensor assemblies can send and receive infrared light pulses, namely infrared light signals, and information transmission can be achieved. The multiple infusion pumps are correspondingly arranged step by step to ensure that the infrared sensor assemblies of each infusion pump can be arranged relatively, and step-by-step infusion information transmission among the multiple infusion pumps can be realized. The specific principle is as follows: the main control chip of the upper-stage infusion pump opens the infrared communication function, the encoded infusion information is sent to the infrared sensor assembly in a pulse form, the infrared sensor assembly emits infrared light pulses, namely infrared light signals, the infrared light pulses enter the infrared sensor assembly of the lower-stage infusion pump and are converted into electric signals through the photosensitive device, and finally the main control chip of the lower-stage infusion pump decodes the electric signals to obtain the infusion information, so that the multi-group pump stacking cascade infusion can be realized.
According to the infusion pump, the infrared sensor assemblies are arranged, so that any multiple infusion pumps 101, multiple injection pumps 102 or combination of the infusion pumps 101 and the injection pumps 102 are guaranteed, when the infusion pumps are used, the infrared sensor assemblies can be oppositely arranged to realize online, and when the infusion pumps are separated from a workstation, the infusion pumps can be directly communicated with one another to perform online work.
Referring to fig. 4 to 5, in the present embodiment, the infrared sensor assembly includes a first infrared sensor 110, a second infrared sensor 120, and a PCB 130 connected to the first infrared sensor 110 and the second infrared sensor 120; when a plurality of infusion pumps are stacked from bottom to top, the second infrared sensor 120 of the infusion pump of the previous stage is in signal connection with the first sensor of the infusion pump of the next stage.
It can be understood that when a plurality of infusion pumps are stacked from bottom to top, the transmission direction of infrared light signals among the infusion pumps can be from top to bottom or from bottom to top, and can be selected according to requirements. The following takes the transmission direction of the infrared light signal from top to bottom as an example: the upper stage infusion pump refers to an infusion pump positioned above, the lower stage infusion pump refers to an infusion pump positioned below, a main control chip in the upper stage infusion pump encodes data information and transmits infrared light pulses, namely infrared light signals, to the first infrared sensor 110 of the lower stage infusion pump through the second infrared sensor 120, then a photosensitive device in the lower stage infusion pump converts the transmitted infrared light pulses into electric signals, and the main control chip in the lower stage infusion pump decodes the electric signals to obtain information to control the infusion pump to work. Therefore, the infrared light signal is gradually downloaded, a plurality of infusion pumps are connected, and the cascade infusion (relay infusion) can be completed without additionally arranging a workstation.
Referring to fig. 4 to 5, in the present embodiment, the first infrared sensor 110 and the second infrared sensor 120 are oppositely installed at two ends of the PCB 130, and the first infrared sensor 110 and the second infrared sensor 120 are located on a same straight line. It can be understood that the first infrared sensor 110 and the second infrared sensor 120 are located on the same straight line, so that when a plurality of infusion pumps are stacked, all the first infrared sensor 110 and the second infrared sensor 120 are located on the same straight line, and the step-by-step transmission of data information is effectively realized. The first infrared sensor 110 and the second infrared sensor 120 are respectively arranged on the side surfaces of the PCB at both ends, the PCB 130 is clamped by the pins of the first infrared sensor 110 and the second infrared sensor 120, and then the first infrared sensor 110 and the second infrared sensor 120 are fixed with the PCB 130 by soldering. With such an arrangement, only one PCB 130 is needed, so that the short distance between the upper and lower ends of the first infrared sensor 110 and the second infrared sensor 120 can be realized, and the production cost can be reduced.
In this embodiment, the pump body 100 is provided with a first infrared window 140 and a second infrared window 150, and the first infrared window 140 is mounted on the PCB 130 and the first infrared sensor 110 and exposed to the top surface of the pump body 100; the second infrared window 150 is mounted under the PCB 130 and the second infrared sensor 120 and exposed to the bottom surface of the pump body 100.
It will be appreciated that when multiple infusion pumps are in a stacked configuration, the second infrared window 150 of the previous infusion pump is in facing relationship with the first infrared window 140 of the next infusion pump. Take the infrared light signal transmission direction from top to bottom as an example: the infrared light signal firstly passes through the second infrared window 150 of the upper stage infusion pump and then enters the lower stage infusion pump through the first infrared window 140 of the lower stage infusion pump, so that the infrared light signal is transmitted step by step. Structurally, the data information transmission direction of the infusion pumps can be from top to bottom or from bottom to top, so that the first infrared window 140 and the second infrared window 150 can be used in a vertical direction, and the cost of the mold is reduced.
In order to prevent water, referring to fig. 4 to 7, in the present embodiment, the first infrared window 140 has an infrared window flange 141, and a sealing gasket 160 is disposed between the infrared window flange 141 and the pump body 100. It is understood that the sealing pad 160 may be in various forms, including but not limited to a silicone pad, which has compressibility and is soft and elastic, and the sealing effect between the first infrared window 140 and the infusion pump can be ensured by interference fit, so as to achieve the purpose of water resistance. In other embodiments, the second infrared window 140 has an infrared window flange with a gasket 160 disposed between the infrared window flange and the pump body 100. The installation tightness of the first infrared window 140 and the second infrared window 150 is ensured.
Referring to fig. 6 to 9, in the present embodiment, the first infrared window 140 and the second infrared window 150 are respectively provided with mounting grooves for two ends of the PCB 130 to be inserted into. The PCB 130 may be vertically inserted into the first infrared window 140 and the second infrared window 150, and may be fixed without screws, thereby ensuring assembly efficiency.
Referring to fig. 7 to 9, in order to further improve the assembly efficiency, in this embodiment, both ends of the PCB are provided with a first fool-proof notch 131 and a second fool-proof notch 132, the infrared window is provided with a third fool-proof notch 133 and a fourth fool-proof notch 134 corresponding to the first fool-proof notch 131 and the second fool-proof notch 132, respectively, the first fool-proof notch 131 is adapted to the third fool-proof notch 133 in shape, and the second fool-proof notch 132 is adapted to the fourth fool-proof notch 134 in shape. It can be understood that the PCB 130 has an upper end and a lower end, and the ends of the upper end and the lower end of the PCB 130 are respectively provided with a first fool-proof notch 131 and a second fool-proof notch 132. Because the first fool-proof notch 131 and the second fool-proof notch 132 are arranged, the operator can directly and unmistakably complete correct operation without spending attention and experience and professional knowledge, thereby not only avoiding the machine or personal injury caused by misoperation of the user, but also preventing misoperation of a new hand and further improving the production efficiency.
Referring to fig. 6, in order to prevent the PCB 130 from being reversely mounted, in this embodiment, a fifth fool-proof notch 135 is disposed on an upper side of the PCB 130, a sixth fool-proof notch 136 is disposed on a lower side of the PCB 130, and the pump body 100 is disposed with a protruding plate capable of extending into the fifth fool-proof notch 135 or the sixth fool-proof notch 136. It can be understood that the PCB 130 has the difference between the upper and lower ends, the PCB 130 has the obvious difference between the upper and lower ends through the fifth fool-proof notch 135 and the sixth fool-proof notch 136 with different shapes and sizes, and the infusion pump extends into the fifth fool-proof notch 135 or the sixth fool-proof notch 136 according to different model settings. Fifth prevent slow-witted breach 135 and sixth prevent slow-witted breach 136 can all be the fillet rectangle setting, the vertical setting of fifth prevent slow-witted breach 135, sixth prevent that slow-witted breach 136 transversely sets up. The fifth fool-proof notch 135 and the sixth fool-proof notch 136 are different in shape and position of the PCB 130, so that the PCB 130 cannot be assembled in the opposite direction even if the assembly in the opposite direction is desired, and the assembly efficiency of a novice can be improved. For example: in one type of infusion pump, the pump body 100 is provided with only the protruding plate extending into the fifth fool-proof notch 135, i.e. the protruding plate can only extend into the fifth fool-proof notch 135 when mounted, and the sixth fool-proof notch 136 is left free. If the PCB 130 is installed in the wrong direction, the PCB 130 cannot be installed, and the arrangement ensures that the PCB 130 cannot be installed in the opposite direction.
In order to avoid that part of natural light enters the first infrared window 140 and the second infrared window 150 to interfere with transmission of infrared light signals, in this embodiment, the first infrared window 140 and the second infrared window 150 are both in a brown translucent arrangement. The semitransparent first infrared window 140 and the second infrared window 150 can ensure that infrared light can be irradiated in, and meanwhile, the dark brown can reduce natural light from being irradiated in the first infrared window 140 and the second infrared window 150, so that the transmission efficiency of infrared light signals is ensured.
Referring to fig. 1 to 3, in the present embodiment, the infusion pump is a syringe pump 102 or an infusion pump 101 of the infusion pump 102. It is understood that when stacked, the plurality of infusion pumps may be only syringe pumps 102, only infusion pumps 101, or a combination of syringe pumps 102 and infusion pumps 101.
By combining all the embodiments, the infusion pump ensures that when any plurality of infusion pumps are in a stacked state, the second infrared sensor 120 of the upper-stage infusion pump is opposite to the first infrared sensor 110 of the lower-stage infusion pump, the infusion pumps are combined and stacked, and then the function of online operation can be realized by setting the cascade serial number, after the infusion of the preset amount of one infusion pump is completed, the infusion pump does not need to manually control the start of the other infusion pump, the infusion pump automatically switches to operate the operating state of the other infusion pump, and when the infusion pumps are separated from a workstation, the pumps can directly communicate with each other and can be operated online.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
