Description

Multi-function oxygen-supplying instrument

This utility model belongs to Medical Instruments, is specifically related to a kind of multi-functional oxygen supply instrument.

Existing various oxygen inhalation apparatus general can only connect a kind of medical apparatus and instruments at every turn, or finishes a kind of function, and purposes is single, function is few.Particularly emergency room, ICU, operating room etc., as open heart surgery with extracorporeal circulation, what need oxygen supply simultaneously has anesthetic machine, respirator, heart-lung machine, a pneumatic breastbone brill etc., for realizing this requirement, often need to use simultaneously the oxygen cylinder more than three, this has not only taken the original just a large amount of areas but also the complicated operation of very nervous operating room, and is very dangerous.

The purpose of this utility model just is to solve above-mentioned weak point, and a kind of new instrument that can realize controlling by all kinds of means the oxygen oxygen supply simultaneously that provides.

Below in conjunction with accompanying drawing this utility model is described in detail.

valve seat

21,23,29. connecting tubes 24 of

valve casing

22,26 passage aisles, coupling sleeve 28,

lock sleeve

30,31, pipe joint

Apparatus for filtering and wetting 12 is made up of insertion tube 13, filtering and wetting bottle 14, pipe joint 15, bottle seat 16, sealing ring 17, passage 18 and flow oxygen pipe joint 1.Bottle seat 16 is fixed on the housing 8, and there is a through hole at the center of bottle seat 16, and the upper end of through hole is connected with pipe joint 31 and connecting tube 29, and the lower end is connected with pipe joint 15 and insertion tube 13, and passage 18 is located at a side of bottle seat 16, and communicates with flow oxygen pipe joint 1.Filtering and wetting bottle 14 is contained on the bottle seat 16, is provided with sealing ring 17 by being threaded between filtering and wetting bottle 14 and the bottle seat 16.

Described choke valve 3 is made up of spool 19, valve seat 20, valve casing 21.The head of spool 19 is the conical surface, and inserts in valve seat 20 taper holes with matching.One passage aisle 22 that is connected with connecting tube 23 is arranged on the valve seat 20, and coupling sleeve 24 is threaded with effusion meter 2, is provided with sealing ring 25 between the two.One side of coupling sleeve 24 has a passage aisle 26 to be connected with pipe joint 27.The upper end of connecting tube 23 links to each other with the air inlet of effusion meter 2, and the lower end links to each other with valve casing 21.Connecting tube 29 is housed on the pipe joint 27, and by lock sleeve 28 with its locking.

Its work process is performed such.(as shown in Figure 2) oxygen is entered by pipe joint 30, the valve port of flowing through.The rotatable spool 19 of inlet, to regulate the aperture size of valve port, its flow is shown by effusion meter 2.Then through the endoporus of passage aisle 22 and connecting tube 23, back down the float of effusion meter 2, arrive the graded tube top of effusion meter 2, and return along the vestlet of effusion meter 2 and the passage between the graded tube, enter in the water of filtering and wetting bottle 14 through passage aisle 26, pipe joint 27, connecting tube 29 and pipe joint 31, therefrom return up behind the filtering and wetting, admission passage 18, flow oxygen pipe joint 1 flow to patient then.

Fig. 3 is the multi-functional oxygen supply instrument of a this utility model fundamental diagram, and the entire work process of this instrument can be described.After the oxygen input, can be divided into left, center, right three tunnel.Left side road oxygen process choke valve 3, the aperture size of how many scalable valve ports of flow, and, supply with patient behind humidifier 12 filtering and wettings after filtration then by effusion meter 2 demonstrations.Mid-way oxygen inserts anesthetic machine through anesthetic machine switch 4, can use for operation.Right wing oxygen is through Pressure gauge 5, and constant pressure pressure-reducing valve 6 transfers out, and can regulate the pressure of constant pressure pressure-reducing valve 6 according to various functional requirements, makes it to be stabilized on a certain value.

Advantages such as the utlity model has the structure uniqueness, easy to use, volume is little, and is in light weight, and function is many because this instrument can be fixed on the wall, have been saved floor space and safe and reliable greatly.For long-term artificial logical oxygen provides convenience, solved and changed the problem that nurse of oxygen cylinder can not finish night.This instrument is specially adapted to the unit at Central oxygen-supply station, realizes that long-range control joins.Can be used for conventional oxygen uptake, rescue the critical patient, ICU.CCU operating room (being intensive care unit(ICU) and cardiovascular care unit), especially one of indispensable equipment and instrument in the open heart surgery with extracorporeal circulation.

Do not have the unit of Central oxygen-supply facility to use this instrument very convenient yet, only need oxygen cylinder to be connected on this instrument, can realize the purpose of a tractor serves several purposes in the same old way with the high pressure oxygen catheter.Generally speaking, anesthetic machine and respirator all can be connected on this instrument, induce the process anesthetic machine, and the maintenance stage is used respirator, and operation is used anesthetic machine again instead before finishing, and under this situation about being used alternatingly, has more shown the characteristics of this instrument.
