Description

Oxygen inhalation timer

Technical field

This utility model relates to a kind of oxygen inhalation timer, especially a kind of oxygen inhalation timer that adopts pneumatic timing gauge tap.

Background technology

At present, patient cures by oxygen therapy in hospital, mainly settles accounts corresponding cost by the actual oxygen time of medical personnel's manual record, and when concrete operations, not only workload is big, and on the accuracy of oxygen uptake timing, often leads to divergence between medical personnel and the patient.For fear of these contradiction, some hospital also adopts single-chip microcomputer to write down patient's oxygen time, but the general break-make of all judging the oxygen therapy gas circuit of this single-chip microcomputer by mechanical contact knob, generally all must transform in the use original oxygen delivery equipment, this is for old hospital, and disposable input is bigger in the transformation.

Summary of the invention

The purpose of this utility model is: at being easy to generate difference between present oxygen therapy timing medical personnel and the patient, especially old hospital uses the instrument record oxygen time, and the bigger practical problem of disposable input provides a kind of oxygen inhalation timer in the transformation.

The purpose of this utility model is achieved in that a kind of oxygen inhalation timer, comprise single-chip microcomputer, it is characterized in that: in the oxygen uptake gas circuit, be provided with pneumatic timing gauge tap, described pneumatic timing gauge tap comprises shell, shell is provided with air inlet and gas outlet, be provided with ball float seat and ball float and be provided with probe in one section uptake ventilator between air inlet and the gas outlet, the detection signal of telecommunication of probe output is connected with the data acquisition input interface of single-chip microcomputer.

The shell of described pneumatic timing gauge tap comprises lower interface and vertical transparent tube, wherein: lower interface is provided with air inlet, and last interface is provided with the gas outlet, and air inlet connects through vertical transparent tube with the gas outlet, air inlet end in the uptake ventilator is provided with the ball float seat, and ball float is located in the vertical transparent tube.

Described pneumatic timing gauge tap can be arranged on through in the oxygen uptake gas circuit behind the humidification bottle.

Described ball float is lighttight material, and probe can adopt the photoswitch with transmitting terminal and receiving terminal, and the transmitting terminal of probe and receiving terminal are located on the tube wall of ball float both sides.

Advantage of the present utility model is: because oxygen inhalation timer oxygen uptake timing signal derives from the detection signal of telecommunication of probe output, and probe is mounted on the pneumatic timing gauge tap, pneumatic timing gauge tap is arranged on through in the oxygen uptake gas circuit behind the humidification bottle, in the use, hospital does not need original oxygen supply device is transformed or changed; Owing to adopted single-chip microcomputer, it is little to have a volume, and the data of record are accurate, in the use, can alleviate medical personnel's working strength, avoids or reduces contradiction between they and the patient.

Among the figure: 1, lower interface, 2, air inlet, 3, vertical transparent tube, 4, the ball float seat, 5, ball float, 6, go up interface, 7, the gas outlet, 8, probe.

The specific embodiment

The nonrestrictive concrete structure sketch map that discloses a kind of pneumatic timing gauge tap that relates among this utility model embodiment of accompanying drawing, and a kind of concrete electrical schematic diagram, the utility model will be further described below in conjunction with accompanying drawing.

As seen from Figure 1, pneumatic timing gauge tap comprises shell, and shell is provided with air inlet 2 and gas outlet 7, is provided with ball float seat 4 and ball float 5 in one section uptake ventilator between air inlet 2 and the gas outlet 7.And being provided with probe 8, the detection signal of telecommunication of probe 8 outputs is connected with the data acquisition input interface of single-chip microcomputer.In the present embodiment, the shell of pneumatic timing gauge tap comprises lower interface 1, goes up interface 6 and vertical transparent tube 3, wherein: lower interface 1 is provided with air inlet 2, last interface 6 is provided with gas outlet 7, air inlet 2 connects through vertical transparent tube 3 with gas outlet 7, air inlet 2 ends in the uptake ventilator are provided with ball float seat 4, ball float 5 is located in the vertical transparent tube, ball float 5 is lighttight material, probe 8 is for having the photoswitch that transmits and receives end, the tube wall that the transmitting terminal of probe 8 and receiving terminal are located at ball float 5 both sides respectively, the model of photoswitch is: H12A5S.

In Fig. 2, IC1 is the cpu chip of single-chip microcomputer, and IC2 is that memory chip, the LCM of single-chip microcomputer is the LCD MODULE of single-chip microcomputer, and in the present embodiment, IC1 selects the AT90S2313 chip, and IC2 selects the 24C02 chip.As seen from the figure, the detection signal of telecommunication of the output of photoswitch through switch triode Q1 and single-chip microcomputer the data acquisition input interface---8 feet of IC1 are connected; 5 feet of memory chip IC2 are connected with 19 feet with 18 feet of IC1 respectively with 6 feet, carry out exchanges data with the external bus storage card simultaneously; LCD MODULE LCM is connected with 15 feet, 16 feet and 17 feet of IC1.

In actual the use, when patients accepting oxygen inhalation, lighttight ball float 5 is by air-flow jack-up, the receiving terminal of photoswitch receives the optical signal of transmitting terminal, make switch triode Q1 conducting, pick up counting, temporal information is recorded among the memory chip IC2, shows oxygen time by LCD MODULE LCM simultaneously; When patient stops oxygen uptake, lighttight ball float 5 is dropping under the effect of gravity on the ball float seat 4, the transmitting terminal of photoswitch and the light path between the receiving terminal are blocked by lighttight ball float 5, switch triode Q1 is ended, stop timing, temporal information originally still is kept among the memory chip IC2, and LCD MODULE LCM still can show original oxygen time; When patient recovers oxygen uptake, made switch triode Q1 conducting once more by the lighttight ball float 5 of air-flow jack-up, and new oxygen time and original oxygen time be accumulated at be recorded among the memory chip IC2, show all previous oxygen time sum by LCD MODULE LCM simultaneously; When patient finally stops oxygen uptake, the information of the final oxygen time that medical personnel can show according to memory chip IC2 or LCD MODULE LCM is settled accounts, with the information zero clearing of oxygen time among the memory chip IC2, the video data of LCD MODULE LCM also makes zero synchronously simultaneously after the clearing.

In the use, skid off from gas outlet 7 owing to be inverted in moving, can establish every deleting or filter the end, gas outlet in uptake ventilator in order to prevent ball float 5.
