In the conventional syringe pump/infusion pump, power supply is required to ensure normal operation of injection/infusion, and working information of the syringe pump/infusion pump is required to be collected through a communication signal, so that a power socket and a communication socket 300 are required to be designed to connect an external power supply and an external communication device. The conventional power outlet and communication outlet 300 of the syringe pump/infusion pump are usually designed as two separate units, and are assembled independently, which results in complicating the process of assembling the syringe pump/infusion pump and increasing the assembly time.

In order to solve the above problems, the present utility model provides an infusion device, which may be an infusion pump or an injection pump.

Referring to fig. 1 to 6, in the present embodiment, the infusion device 10 includes a housing 100, a power outlet 200, a communication outlet 300, and a mounting platen 400. The housing 100 is provided with a first through hole 110 and a second through hole 120; the power socket 200 is provided with a power socket 210 communicated with the first through hole 110, and the power socket 210 is used for being connected with an external power plug; the communication socket 300 is provided with a communication slot 310 communicated with the second through hole 120, and the communication slot 310 is used for being connected with an external communication plug; the installation pressing plate 400 is connected with the power socket 200 and the communication socket 300, and the installation pressing plate 400 is used for fixing the power socket 200 and the communication socket 300 in the shell 100.

When the infusion device 10 is installed, the power socket 200 and the communication socket 300 are installed and connected on the installation pressing plate 400, then the power socket 210 and the communication socket 310 are aligned with the first through hole 110 and the second through hole 120 respectively, so that the power socket 210 is communicated with the first through hole 110, the communication socket 310 is communicated with the second through hole 120, and then the installation pressing plate 400 is connected to the housing 100, so that the power socket 200 and the communication socket 300 are fixed in the housing 100. After the installation pressing plate 400 is connected with the power socket 200 and the communication socket 300, the power socket 200 and the communication socket 300 can be regarded as a whole, and the power socket 200 and the communication socket 300 can be assembled in the shell 100 only by fixing the installation pressing plate 400 in the shell 100, so that independent assembly of the power socket 200 and the communication socket 300 is avoided, the assembly process is simplified, and the assembly time is saved.

Referring to fig. 5 and 7, in an embodiment, the power socket 200 includes a power socket body 220, and a first limit portion 230 and a second limit portion 240 connected to the power socket body 220, and the mounting pressing plate 400 is sleeved outside the power socket body 220 and is limited between the first limit portion 230 and the second limit portion 240.

Specifically, the second limiting portion 240 includes a limiting plate 241, the limiting plate 241 is connected to the power socket body 220 and extends toward the first limiting portion 230, and the limiting plate 241 is elastically compressible. The mounting pressing plate 400 is provided with a first mounting hole 410 adapted to the outer periphery of the power socket 200, and one end of the power socket 200 connected with the power socket body 220 by the limiting plate 241 is inserted into the first mounting hole 410. Since the limiting plate 241 is elastically compressible, the limiting plate 241 receives the compression of the mounting plate 400 when passing through the first mounting hole 410, and after the limiting plate 241 integrally passes through the first mounting hole 410, the limiting plate 241 is restored and the power socket body 220 is limited to exit from the first mounting hole 410, and the mounting plate 400 is limited between the first limiting portion 230 and the second limiting portion 240.

When the distance between the first limiting portion 230 and the second limiting portion 240 is set to be the thickness of the mounting platen 400, the mounting platen 400 is clamped between the first limiting portion 230 and the second limiting portion 240, and the power socket 200 is fixed on the mounting platen 400. In order to maintain the stability of the connection between the power socket 200 and the mounting platen 400, the first limiting portion 230 and the second limiting portion 240 may be symmetrically disposed on two sides of the power socket body 220, or may be circumferentially disposed on the outer side of the power socket body 220, or one of the first limiting portion 230 and the second limiting portion 240 may be symmetrically disposed on two sides of the power socket body 220, and the other one may be circumferentially disposed on the outer side of the power socket body 220. It can be appreciated that the power socket 200 is fixedly connected with the mounting platen 400 through the structural design of the first limiting portion 230 and the second limiting portion 240, and no components such as an adhesive or a screw 600 are required to be added, so that the assembly process of the infusion device 10 is further simplified, and the assembly cost and time are saved.

Referring to fig. 6 and 8, in an embodiment, the communication socket 300 includes a communication socket body 320 and a first positioning post 340 connected to the communication socket body 320, the first positioning post 340 extends along an axial direction of the communication socket body 320, a corresponding first positioning hole 430 is formed in the mounting platen 400, and the communication socket body 320 is fixedly connected to the mounting platen 400 through the first positioning post 340 and the first positioning hole 430.

Specifically, the mounting pressing plate 400 is provided with an avoidance hole 420 adapted to the periphery of the communication socket body 320, and when the communication socket body 320 penetrates into the avoidance hole 420, the first positioning column 340 is inserted into the first positioning hole 430, so as to realize the fixed connection between the mounting pressing plate 400 and the communication socket 300. The first positioning post 340 may extend toward the opening 421 of the communication slot 310, where the communication socket 300 is inserted into the avoidance hole 420 from the end provided with the communication slot 310; the first positioning post 340 may also extend in a direction opposite to the opening 421 of the communication slot 310, and at this time, the communication socket 300 is inserted into the avoidance hole 420 from an end opposite to the communication slot 310. Preferably, the first positioning column 340 is disposed at the communication socket body 320 near one end of the communication slot 310 and extends in a direction opposite to the opening 421 of the communication slot 310, so that the first positioning column 340 does not pass through one end of the first positioning hole 430 to abut against the housing 100 after the mounting pressing plate 400 is connected with the housing 100, thereby preventing the first positioning column 340 from sliding out from the first positioning hole 430. Further, to enhance the connection stability between the first positioning posts 340 and the first positioning holes 430, the number of the first positioning posts 340 is multiple, and the first positioning holes 430 are circumferentially spaced from the outside of the communication socket body 320, and the first positioning posts 340 are correspondingly multiple.

Referring to fig. 4, considering that an end of the communication socket 300 facing away from the communication slot 310 needs to be connected with a circuit board, the communication socket 300 is not easy to penetrate into the avoidance hole 420, in an embodiment, the avoidance hole 420 has an opening 421 facing away from the power socket 200, and the size of the opening 421 is not smaller than the outer diameter of the communication socket body 320. The communication socket body 320 moves radially, is inserted into the avoidance hole 420 through the opening 421, and then moves axially, so that the first positioning post 340 is inserted into the first positioning hole 430.

In order to enable the communication socket body 320 to pass through the opening 421, the opening 421 is required to be sized not smaller than the outer diameter of the communication socket body 320, and accordingly, when the communication socket 300 is connected to the mounting plate 400, the communication socket 300 is easily inclined toward the opening 421, resulting in the communication socket 300 being separated from the mounting plate 400. Therefore, the communication socket 300 further includes a rib 330 connected to the outer wall of the communication socket body 320, and when the communication socket body 320 passes through the avoidance hole 420, the rib 330 is limited on the mounting pressing plate 400, and the rib 330 abuts against the mounting pressing plate 400, so as to prevent the communication socket 300 from tilting toward the direction of the opening 421. Preferably, the ribs 330 are circumferentially disposed on the periphery of the communication socket body 320, the first positioning columns 340 are disposed on the ribs 330, and when the mounting press plate 400 is connected to the housing 100, the ribs 330 are limited between the inner wall of the housing 100 and the mounting press plate 400, so that the connection stability of the communication socket 300 and the mounting press plate 400 is improved.

The communication slot 310 is generally circular, and when the second through hole 120 and the communication slot 310 are aligned, the communication socket 300 rotates at different angles, while still communicating with the second through hole 120, but the external communication plug also needs to rotate at different angles to connect with the communication socket 300, that is, the product consistency of the infusion device 10 is poor, which affects the normal use of the infusion device 10.

Referring to fig. 3 and 6, in one embodiment, the communication socket 300 further includes a positioning protrusion 350, the positioning protrusion 350 is disposed on a side of the protruding rib 330 near the communication slot 310, and the positioning groove 130 corresponding to the positioning protrusion 350 is disposed on the inner wall of the housing 100. When the second through hole 120 and the communication slot 310 are opposite to Ji Liantong, the positioning protrusion 350 is only required to be inserted into the positioning slot 130, so that the installation angle of the communication socket 300 can be fixed, and the consistency of the infusion device 10 is ensured.

The attachment means of the mounting plate 400 to the housing 100 include, but are not limited to, adhesive, snap-fit connection, screw 600 connection, etc. Taking the screw 600 as an example, the mounting pressing plate 400 is provided with a screw hole 440, and the mounting pressing plate 400 is connected with the housing 100 through the screw 600. Since the first limiting portion 230 and the rib 330 are limited between the inner wall of the housing 100 and the mounting plate 400, that is, a gap exists between the inner wall of the housing 100 provided with the first through hole 110 and the second through hole 120 and the mounting plate 400, if the housing 100 and the mounting plate 400 are directly connected by the screw 600, the mounting plate 400 is easily shaken in the gap space, and the stability of the connection of the mounting plate 400 and the housing 100 is damaged.

Referring to fig. 2 and 3, in one embodiment, a mounting post 140 is disposed on an inner wall of the housing 100, a nut 141 is embedded in the mounting post 140, a corresponding screw hole 440 is disposed on the mounting pressing plate 400, and the mounting pressing plate 400 is connected to the nut 141 in the mounting post 140 through a screw 600 to achieve connection with the housing 100. The mounting press plate 400 is connected with the mounting post 140 and then abuts against the mounting post 140, and the mounting post 140 plays a supporting role on the mounting press plate 400, so that shaking of the mounting press plate 400 is reduced. To enhance the stability of the connection between the mounting plate 400 and the housing 100, the mounting plate may be symmetrically disposed on both sides of the power socket 200 and the communication socket 300.

Referring to fig. 3, considering that the screw holes 440 are required to be aligned with the mounting posts 140 when the mounting is coupled to the mounting posts 140, the number of the mounting posts 140 is plural, and the position of the mounting plate 400 is easily shifted when the screw 600 is used for coupling mounting, thereby increasing difficulty of assembly and mounting. Therefore, on the basis of the above embodiment, the positioning rib assembly 150 is disposed on the inner wall of the housing 100 abutting against the mounting platen 400, the positioning rib assembly 150 includes a first positioning rib 151 disposed along the axial direction of the power socket 200, and a second positioning rib 152 disposed perpendicular to the first positioning rib 151, and the mounting platen 400 abuts against the first positioning rib 151 and the second positioning rib 152. If the inner wall of the housing 100 provided with the first through hole 110 and the second through hole 120 is a side wall, the inner wall of the housing 100 abutting against the mounting platen 400 is a bottom wall, or is a side wall adjacent to the inner wall of the housing 100 provided with the first through hole 110 and the second through hole 120, the first positioning rib 151 is axially arranged along the power socket 200, the second positioning rib 152 is vertically arranged with the first positioning rib 151, and when the mounting platen 400 abuts against the first positioning rib 151 and the second positioning rib 152 at the same time, the position of the mounting platen 400 in the housing 100 is determined. The screw holes 440 of the mounting plate 400 are aligned with the mounting posts 140, so that the alignment step when the mounting plate 400 is connected with the mounting posts 140 can be simplified, i.e. the difficulty in assembling the infusion device 10 is further reduced.

Referring to fig. 2 and 9, in an embodiment, in order to prevent external liquid from penetrating into the gap between the housing 100 and the power socket 200 from the first through hole 110 or penetrating into the gap between the housing 100 and the communication socket 300 from the second through hole 120, the infusion device 10 further includes a waterproof pad 500, an installation groove 160 adapted to the waterproof pad 500 is concavely formed on the inner wall of the housing 100, and the waterproof pad 500 is provided with a third through hole 510 and a fourth through hole 520 corresponding to the power socket 210 and the communication socket 310. Preferably, the waterproof pad 500 is made of silica gel, and the silica gel has better toughness and elasticity, is not easy to permanently deform due to external force, and has longer service life.

Further, a second positioning post 170 is disposed on the housing 100, a corresponding second positioning hole 530 is disposed on the waterproof pad 500, and when the waterproof pad 500 is mounted in the mounting groove 160, the second positioning post 170 is inserted into the second positioning hole 530. When the waterproof pad 500 is installed in the installation groove 160, the second positioning post 170 may be inserted into the second positioning hole 530, so as to facilitate the alignment and installation of the waterproof pad 500 and the installation groove 160; meanwhile, the connection between the second positioning post 170 and the second positioning hole 530 can also prevent the waterproof pad 500 from being separated from the mounting groove 160.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
