Abstract
The utility model discloses an automatic oxygen therapy adjusting device. A piston is arranged in a piston pipe. A pressure spring is arranged on the upper side of the piston. A threaded cover is arranged at the lower end of the piston pipe. A gas inlet groove is formed in the front side wall of the piston pipe, and a gas outlet groove is formed in the rear side wall of the piston pipe. A gas inlet pipe is connected with the gas inlet groove. A gas outlet pipe is connected with the gas outlet groove. A gas inlet branch pipe communicated with the piston pipe is connected with the threaded cover. The other end of the gas inlet branch pipe is connected with the gas inlet pipe. A groove type valve hole for communicating the gas inlet groove with the gas outlet groove is formed in the piston. The gas inlet groove and the gas outlet groove are completely communicated when the pressure spring is in a natural state, and the gas inlet groove and the gas outlet groove are partially communicated when the pressure spring bears pressure and contracts, that is, the piston partially blocks the gas inlet groove and the gas outlet groove. The automatic oxygen therapy adjusting device is simple in structure, low in cost and convenient to operate, the output speed can be automatically adjusted according to the magnitude of oxygen pressure in a container, then the oxygen output amount keeps stable, and therefore the oxygen therapy effect is ensured, and burdens on medical staff are reduced.
Description
Technical field
This utility model relates to a kind of medical instruments, relates in particular to a kind of oxygen therapy self-checking device.
Background technology
Conventionally adopt clinically oxygen bag, oxygen cylinder etc. easily to store the oxygen sucking for patient, in the time that in container, amount of oxygen is more, oxygen pressure is larger, along with the minimizing of amount of oxygen, the pressure of oxygen diminishes gradually, and this just causes the flow velocity of oxygen in output procedure unstable, oxygen therapy poor effect; Change for reducing oxygen gas flow rate the impact bringing, conventionally need artificially regularly to regulate, operation is trouble comparatively, wastes time and energy.
Utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure, with low cost, easy to operate that this utility model provides, and can automatically regulate according to oxygen pressure size in container the oxygen therapy self-checking device of oxygen output speed.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of oxygen therapy self-checking device, comprise a piston tube, and in piston tube, be provided with the piston being slidably matched with it, described piston upside is provided with compression spring; Described piston tube lower end is provided with the threaded cap being sealed and matched; The front side wall of described piston tube longitudinally has air inlet duct, and rear wall longitudinally has outgassing groove, and described air inlet duct and outgassing groove are with the central shaft symmetry of piston tube; Described air inlet duct side is connected with air inlet pipe, and described outgassing groove side is connected with escape pipe, is connected with the air intake branch communicating with piston tube on described threaded cap, and this air intake branch other end is connected with air inlet pipe; On described piston, have one for being communicated with the grooved valve opening of air inlet duct and outgassing groove, compression spring in the raw time air inlet duct be communicated with completely with outgassing groove, compression spring is stressed while contraction, and air inlet duct is communicated with outgassing groove part, and air inlet duct and outgassing groove are carried out part shutoff by piston.
Described piston tube is fixed in a housing, and housing is provided with two joints outward, and escape pipe and air inlet pipe are connected respectively at two joints.
Described compression spring upside is provided with spring pad, and the upper end of described spring pad is provided with adjusting screw(rod), and adjusting screw(rod) upper end extends to outside piston tube, and adjusting screw(rod) upper end is provided with adjusting tap, and the upper end of piston tube is provided with the screwed hole coordinating with adjusting screw(rod).
The utlity model has following beneficial effect: in the time that the oxygen pressure in container is larger, oxygen enters piston underside, provide a thrust upwards to piston, piston overcomes the part thrust of compression spring and moves up, make the action section of air inlet duct and outgassing groove by piston shutoff one branch, thereby avoid that oxygen pressure is large and the velocity of discharge is too fast; Along with the minimizing of amount of oxygen, the air pressure thrust that piston underside is received reduces gradually, and piston moves down, and makes air inlet duct be communicated with cross section with outgassing groove and becomes gradually greatly, thereby avoid oxygen pressure in container to reduce and flow velocity deficiency.This utility model is simple in structure, with low cost, easy to operate, can carry out automatic regulation output speed according to the size of oxygen pressure in container, and then make oxygen keep stable output, ensures thus oxygen therapy effect, reduces medical worker's burden.
