TECHNICAL FIELD

[0001] The utility model relates to infusion equipment field, concretely relates to centralized infusion detection control device and infusion apparatus. BACKGROUND

[0002] Intravenous infusion is a method of using atmospheric pressure and hydrostatic pressure principle to input a large amount of sterile liquid, electrolyte and drug into the body through the vein. In the prior art, the liquid medicine is generally filled into an infusion bottle or an infusion bag, and then an infusion pipeline and an infusion needle are connected to the infusion container, so that the liquid medicine in the infusion container is gradually delivered into the body of the infusion object through the infusion pipeline.

[0003] In the actual infusion process, the person cannot always pay attention to the remaining amount of the liquid in the infusion bottle / bag during the infusion process, and if the liquid input is completed without timely needle extraction, it will cause back bleeding or air entering the infusion object, and other situations such as air embolism, which endanger the safety of the life of the infusion object.

[0004] Chinese patent publication No. CN106237434A discloses an automatic infusion apparatus, which can solve the above problems to some extent. The patent discloses an electric actuator, which includes a rotating core and a fixed block arranged outside the rotating core. The rotating core is driven to rotate by a motor in communication with a controller. The top end of the fixed block is connected with a manual rotating ring having an opening. The rotating core and the fixed block have infusion tube embedding grooves corresponding to the opening of the manual rotating ring for embedding the branch pipe. During infusion, when the infusion tube embedding groove of the rotating core is consistent with the infusion tube embedding groove of the fixed block, the liquid can flow normally in the infusion tube. When the sensor detects that the liquid is about to be infused, the controller controls the motor to drive the rotating core to rotate, the direction of the infusion tube embedding groove is deflected, the infusion tube is bent, the liquid flow is blocked, and the liquid supply is stopped.

[0005] However, the automatic infusion apparatus of the patent has the following disadvantages: the controller and the electric actuator of the automatic infusion apparatus of the patent are separately arranged, and the controller and the electric actuator occupy a certain space, thereby causing the automatic infusion apparatus to have a large volume, which is not convenient for transportation and use, and the subsequent assembly of the infusion apparatus is also troublesome.

[0006] In addition, after the infusion tube passes through the fixed block and the rotating core, an additional manual rotating ring is needed to limit the infusion tube, and the manual rotating ring has a small volume, which is not convenient for rotating operation of the manual rotating ring. Moreover, the manual rotating ring is located at the top end of the fixed block, and the structure of the manual rotating ring to some extent hinders the infusion tube from being put into the embedding grooves of the fixed block and the rotating core.

[0022] This embodiment also includes an electric gate opener, which is mounted on the control box 1. Specifically, the control box 1 has a receiving groove 2 on its side wall, and the installation position is located in the receiving groove 2. Thus, the electric gate opener is installed in the control box 1 by being mounted in the receiving groove 2. By providing the receiving groove 2, the electric gate opener is prevented from protruding from the control box 1, which helps to reduce space occupation. In this embodiment, multiple electric gate openers can be installed in the receiving groove 2. Of course, in other embodiments, multiple receiving grooves 2 can be provided, with one or more electric gate openers installed in each receiving groove 2.

[0023] In the embodiment, the electric actuator is used to bend or clamp the infusion tube to block the liquid flow. The specific structure includes a positioning seat 8 and a rotating seat 7 connected to the electric motor, and the rotating seat 7 is fixedly connected to the output shaft of the steering engine. The positioning seat 8 is integrally formed or fixedly installed in the accommodating groove 2 of the control box 1. The middle part of the positioning seat 8 is provided with a matching hole penetrating through the positioning seat 8, and the bottom wall of the accommodating groove 2 of the control box 1 is provided with a through hole coaxially arranged with the matching hole. The rotating seat 7 is rotatably connected to the matching hole through the through hole. One end of the rotating seat 7 extends into the cavity of the control box 1 and is connected to the output shaft of the steering engine. The outer wall of the rotating seat 7 and the inner wall of the matching hole are provided with a blocking gap 18 for clamping the infusion tube. In the embodiment, the number of electric actuators is two, which can simultaneously block two infusion tubes. Of course, in other embodiments, other numbers of electric actuators can also be provided.

[0024] In the embodiment, the top surface of the positioning seat 8 is provided with an outer connecting groove for the infusion tube to pass through, and the outer connecting groove is vertically arranged. The top surface of the rotating seat 7 is provided with an inner connecting groove 10 for the infusion tube to pass through, Figure 1 and the inner connecting groove 10 in the rotating seat 7 is vertically arranged. When the rotating seat 7 is rotated to make the inner connecting groove 10 opposite to the outer connecting groove, the inner connecting groove 10 and the outer connecting groove are connected in a straight line, and the infusion tube can pass through the inner connecting groove 10 and the outer connecting groove in a straight line.

[0025] In the embodiment, the cover plate 4 is movably connected to the control box 1. The specific movement mode can be sliding connection, rotating connection, clamping, etc. In the embodiment, the rotating connection mode is adopted. Specifically, one side of the accommodating groove 2 of the control box 1 is provided with a rotating groove 17, and the end of the rotating groove 17 is provided with a rotating shaft 5 (the rotating shaft 5 can be integrally connected to the control box 1, or the rotating shaft 5 can not be integrally connected to the control box 1, but is a separate component that can be detachably inserted and assembled in the rotating groove 17). The cover plate 4 is integrally formed with a rotating part 16 located in the rotating groove 17. The rotating part 16 is provided with a rotating hole 6. The rotating shaft 5 and the rotating hole 6 are matched to realize the rotating connection of the cover plate 4 and the control box 1. Of course, in other embodiments, the positions of the rotating shaft 5 and the rotating hole 6 can be interchanged. In the embodiment, the cover plate 4 is made of plastic material and can be slightly deformed under external force, so as to realize the normal assembly of the rotating shaft 5 and the rotating hole 6.

[0026] Thus, the control box 1 of the centralized infusion detection control device in the embodiment is fixed on the infusion support by screwing, screwing or clamping, the infusion bottle or bag is placed at the top of the infusion support, the infusion bottle or bag is above the control box 1, the infusion tube vertically passes through the inner connecting groove 10 and the outer connecting groove of the electric on-off device, and then the cover plate 4 is covered at the accommodating groove 2. The cover plate 4 limits the infusion tube in the electric on-off device, which can prevent the infusion tube from being separated from the inner connecting groove 10 and the outer connecting groove of the electric on-off device.

[0027] In actual use, the control box 1 is further provided with a detector on the outside for detecting whether the liquid in the infusion bottle is exhausted.

[0028] In the embodiment, when the infusion bottle is exhausted, the detector detects the change of the liquid in the infusion tube and generates a detection signal, and then the detector transmits the detection signal to the single-chip microcomputer. After receiving the detection signal, the single-chip microcomputer generates a control signal and transmits the control signal to the steering engine. The steering engine drives the rotating seat 7 to rotate, and when the rotating seat 7 rotates, the infusion tube in the inner connecting groove 10 is rotated, so that the infusion tube is wound into the blocking gap 18, the infusion tube is bent, and the liquid is blocked to stop the infusion, so as to block the liquid in the infusion tube and stop the flow of the liquid in the infusion tube, thereby achieving the pause of the infusion.

[0029] When the infusion is no longer paused or completed, the single-chip microcomputer controls the steering engine in reverse, and the inner connecting groove 10 and the outer connecting groove are turned to the relatively communicating state. At this time, the infusion tube is in a smooth state again, then the cover plate 4 is opened, the electric on-off device is exposed, and the cover plate 4 is no longer limited.
