This section is an example of the present invention and is provided to explain and illustrate the technical solutions of the present invention.

An automatic switching device of an infusion bottle comprises a shell 1, wherein a plurality of infusion tube sockets A3 are arranged above the shell 2, an infusion tube socket B4 is arranged below the shell 1, a plurality of respectively separated infusion channels 5 connected with the infusion tube sockets A3 are arranged in the shell 1, the infusion tube sockets B4 are connected below all the infusion channels, and the automatic switching device further comprises a control circuit 6, and the control circuit 6 is connected with and controls the opening and closing of each infusion channel.

The plurality of infusion channels 5 are a plurality of infusion tubes, each infusion tube is provided with a clamping type pressure sensor and a clamping switch valve, and the control circuit 6 is connected with and controls all the clamping type pressure sensors and the clamping switch valves.

N infusion tube sockets A3 and n infusion channels 5 are respectively arranged, the n infusion tube sockets A3 are respectively a first infusion tube socket A3-1, a second infusion tube socket A3-2 to an nth infusion tube socket A3-n, and the n infusion channels 5 are respectively a first infusion channel 5-1, a second infusion channel 5-2 to an nth infusion channel 5-n; the shell 1 is provided with marks from 1 to n corresponding to the positions of a first infusion tube faucet A3-1, a second infusion tube faucet A3-2 to an nth infusion tube faucet A3-n.

The shell 1 is also provided with a state display dial, the state display dial comprises a power lamp, a work completion lamp, an electric quantity display lamp and a fault lamp, and a channel working state lamp is arranged beside the marks of the n infusion tube sockets A.

The shell 1 is also provided with a reset switch 7, and the reset switch 7 is connected with the control circuit 6.

The lateral surface of the shell 1 is provided with lugs and fastening screws, the lugs are made of elastic materials, the space between the lugs is matched with the rod body of the infusion hanging rack, the lateral sides of the lugs are provided with threaded holes communicated in position, and the fastening screws enable the lugs to be tightly pressed through the threaded holes of the lugs.

Another embodiment of the present invention is described below with reference to the drawings.

Firstly, the device is arranged on an infusion hanger, or the device is always arranged on the infusion hanger.

An infusion bottle or an infusion bag needing to be infused firstly is connected with a first infusion tube socket A3-1 through a universal infusion tube, then infusion bottles or infusion bags of other medicines are sequentially connected with a second infusion tube socket A3-2, a third infusion tube socket A3-3 and the like according to an infusion sequence until all the infusion bottles or infusion bags are connected with the device, then the infusion tube with the needle is inserted into a high infusion tube socket B4, a reset switch or an opening device switch is pressed, after the liquid medicine flows out from the infusion tube with the needle, the liquid flow of the infusion tube with the needle is closed, the needle is inserted into a venous blood vessel of a patient, and infusion is started.

When the reset switch is pressed or the device is just powered on, the holding switch valve of the first infusion channel 5-1 is in an open state, and the holding switch valves of the other infusion channels 5 are in a closed state.

When the clamping type pressure sensor of the first transfusion channel 5-1 detects that the transfusion tube of the first transfusion channel 5-1 is empty tube pressure, the control circuit 6 controls the clamping switch valve of the first transfusion channel 5-1 to be switched to a closed state, and then the control circuit 6 controls the clamping switch valve of the second transfusion channel 5-2 to be switched to an open state; then, the pressure of an infusion tube of the second infusion channel 5-2 is detected through a clamping type pressure sensor of the second infusion channel 5-2, and when the pressure of the infusion tube of the second infusion channel 5-2 is detected to be empty tube pressure, the control circuit 6 controls a clamping switch valve of the second infusion channel 5-2 to be switched to a closed state; then the control circuit 6 controls the clamping switch valve of the third transfusion channel 5-3 to be switched to the opening state, and so on until the clamping switch valve of the nth transfusion channel 5-n is switched to the opening state and then switched to the closing state.

According to the mechanism, when the transfusion channel which is not connected with a transfusion bottle or a transfusion bag at the back is opened, the clamping type pressure sensor of the transfusion system detects that the transfusion channel is empty pipe pressure, and the channel is immediately switched to a closed state. Therefore, no matter how many infusion bottles or infusion bags need to be used, the nurse can connect the infusion bottles or the infusion bags according to the sequence of the insertion openings A of the infusion tubes without performing other selection and adjustment works; even if the sequence is correct, the device with the middle separation channel can still be used, for example, two bottles of liquid need to be infused, a first bottle of nurse can connect the device with the second infusion tube socket A3-2, a second bottle of nurse can connect the device with the fifth infusion tube socket A3-5, the device can convey the medicine connected with the second infusion tube socket A3-2 in sequence firstly and then convey the medicine connected with the fifth infusion tube socket A3-5, the operation of the nurse is greatly facilitated, and the fault tolerance is reduced.

The state display dial is a prompting device of the device, and when the device is powered on or the switch is turned on, the power lamp is turned on. When all infusion passageways all accomplished the work, the work completion lamp lights, and under the intelligent environment, the signal of work completion lamp can be sent for the nurse station through signal transmitter, reminds the nurse to accomplish remaining work. The electric quantity display lamp is used when the device uses a built-in power supply, and when the electric quantity of the power supply is lower than a certain voltage value, the electric quantity display lamp is lightened to remind a nurse to replace the power supply. The fault lamp is lighted when the control circuit 6 is in fault connection with other elements. And when the clamping switch valves of the infusion channel are in an open state, the channel working state lamp of the infusion channel is lightened, so that the infusion channel is in a working state.

This device uses the auricle to fix on current infusion stores pylon, and infusion bottle or infusion bag are hung to the infusion stores pylon, and the nurse accomplishes every infusion or infusion bag's installation back according to the order, just can realize automatic infusion and switch, and all operations do not all bring extra work for the nurse, can also save time greatly, improve work efficiency. In addition, the used infusion hanger, infusion bottle, infusion bag and infusion tube are all general articles used at present, so that the device can be directly used in all hospitals and almost does not need additional training.
