Abstract
The utility model discloses a medical oxygen transfer device, which can sense whether the oxygen flow exceeds the preset range or not. The medical oxygen transfer device consists of a reducing valve, a flowmeter and a humidifier, wherein the flowmeter comprises a floating ball and a graduated tube; the graduated tube is connected with the reducing valve; the floating ball is positioned in the graduated tube; a conductor is arranged on the surface of the floating ball; and a pair of lower electrode plates is arranged on the lower part of the graduated tube and electrically connected with a warning device. When the oxygen flow is oversmall and overlarge, the floating ball switches on a power supply of the warning device and the warning device sends out a warning signal to require medical workers to increase or reduce the oxygen flow, so that the monitoring pressure on the medical workers can be relieved and the oxygen transfer safety is improved.
Description
Technical field
This utility model relates to medical apparatus and instruments, the oxygen breathing apparatus that is particularly useful for curing by oxygen therapy.
Background technology
Oxygen breathing apparatus is made up of air relief valve, effusion meter and humidifier.Air relief valve connects oxygen cylinder or pipeline oxygen, and oxygen cylinder or pipeline oxygen enter effusion meter after the air relief valve decompression, and the water container humidification of flowing through could be cured by oxygen therapy to the patient.The oxygen therapy process is to carry out in silent, air pressure change appears in source of oxygen, when causing oxygen flow excessive or too small, people seldom can aware, and flow is excessive or too smallly all can cause discomfort even injury to the patient, under extreme case, the oxygen cylinder source of the gas exhausts or blocking appears in pipeline oxygen, given patient's oxygen supply, but the nursing staff do not aware still, this just fatal accident may occur.
Summary of the invention
The purpose of this utility model is to provide a kind of energy perception oxygen flow whether to exceed the oxygen supply device of preset range.
This utility model oxygen breathing apparatus is made up of air relief valve, effusion meter, humidifier, and effusion meter comprises ball float and graded tube, and graded tube connects air relief valve, ball float is arranged in graded tube, the ball float surface is a conductor, and a pair of lower electrode plate is arranged at the graded tube bottom, and this lower electrode plate is electrically connected with alarm device.
Above-mentioned lower electrode plate can connect lifting support, the lifting support connecting screw rod, and this screw spiral connects a connecting rod, and this interlinking lever end has knob.
A pair of electric pole plate can also be arranged at above-mentioned graded tube top, and this electric pole plate is electrically connected with alarm device.
Above-mentioned electric pole plate can be by the corresponding lower electrode plate that connects of the metallic plate that is adjacent to the graded tube tube wall.
This utility model is when oxygen flow is too small, ball float sinks on bottom electrode owing to own wt, connected the alarm device power supply, alarm device sends alarm signal, requires medical personnel to heighten oxygen flow, when oxygen flow is excessive, ball float floats to top electrode and has connected top electrode, makes alarm device send alarm signal, requires medical personnel to turn down oxygen flow, can alleviate medical personnel's monitoring pressure thus, improve the oxygen therapy safety.
Description of drawings
Fig. 1 is a kind of embodiment sketch map of this utility model.
Fig. 2 is effusion meter and sleeve pipe cutaway view thereof.
The specific embodiment
Fig. 1 illustrates a kind of embodiment of this utility model, and this oxygen breathing apparatus comprises gas source connector 1, air relief valve 2, effusion meter 3 and humidifier 4.After oxygen inserts from gas source connector 1, through air relief valve 2 decompression, flow out from effusion meter 3 bottoms, enter conduit 6 in the humidifier 4 through effusion meter trocar sheath 5 again, the under water formation bubble of conduit 6 from humidifier 4 be eruption upwards, discharges the oxygen therapy for the patient from oxygen catheter interface 7 again.
As shown in Figure 2, effusion meter 3 comprises ball float 10, graded tube 11, the bore of graded tube 11 increases from top to bottom gradually, oxygen flows out from the crack between ball float 10 and the graded tube 11, when flow reaches a certain amount of, and ball float 10 come-ups, after arriving certain altitude, power and ball float 10 gravitational equilibriums that flow of oxygen produces, ball float 10 no longer floats, and the oxygen flow of ball float 10 positions is represented on graded tube 11 scales.
There is the coat of metal on ball float 10 surfaces, make its surface become conductor, and a pair of lower electrode plate 12 is arranged at the bottom of graded tube 11, and lower electrode plate 12 is electrically connected with alarm device.During less than certain numerical value, ball float 10 sinks on bottom electrode 12 at oxygen flow, and alarm device sends alarm signal by bottom electrode 12 and ball float 10 surperficial turn-on powers, requires medical personnel to heighten oxygen flow.Lower electrode plate 12 bottoms connect lifting support 13, lifting support 13 bottom connecting screw rods 14, these screw rod 14 spirals connect a connecting rod 15, sleeve pipe 5 has trepanning 16 in connecting rod 15 positions, connecting rod 15 passes this trepanning 16 and is sealed by sealing shroud 17, and connecting rod 15 ends have knob 18 to be positioned at my outer wall of sleeve pipe 5.Rotary knob 18 moves up and down screw rod 14 by connecting rod 15, can realize the lifting of bottom electrode 12 positions, determines the minimum warning flow of oxygen thus.
Graded tube 11 tops also have a pair of electric pole plate 20, and this electric pole plate 20 connects lower electrode plate 12 accordingly by the metallic plate 21,22 of the tube wall that is adjacent to graded tube 11.Thus, when oxygen flow was excessive, ball float 10 rose and contacts electric pole plate 20, makes the alarm device turn-on power, sends alarm signal, requires medical personnel to turn down oxygen flow.
Alarm device can be known alarm device, as long as its input is that the current switching signal just can use, alarm device can fit together with this utility model device, also the nurse job chamber can be installed.
