Abstract
The utility model relates to an oxygen inhalator with improved structure, which comprises a valve body assembly on the upper part thereof, wherein the valve body assembly consists of a valve body, an oxygen inlet mouth, an oxygen inlet measuring mechanism of connecting pipe, a pressure-regulating valve and an oxygen output pipe connector, as well as an external thread baffle, and the external thread baffle is in spiral connection onto the lower end the valve body assembly. A bell mouth provided with a plug and matched with the connector of the oxygen output connector is connected onto the external thread baffle as well, and the plug can be matched with the bell mouth. When a throwaway humidification bag is used, the external thread baffle can be connected to the lower end of the valve body assembly in a spiral way, so as to reduce the possibility of iatrogenic cross infection to the maximum extent. A humidification bottle can be adopted to replace the humidification bag as long as the external thread baffle is screwed off, and the humidification bottle is screwed on. The utility model has the advantages of simple structure, low cost and more sanitary usage.
Description
(1) technical field:
This utility model relates to a kind of medical apparatus and instruments, especially a kind of oxygen inhalation apparatus that improves structure.
(2) background technology:
At present, the oxygen inhalation apparatus that uses in the concentrated oxygen supply system of medical institutions is made up of the humidification bottle that superposed valve component and spiral are connected in the valve component bottom, described valve component is by valve body, oxygen inserts mouth, connection tube, oxygen stoichiometry mechanism, pressure regulator valve and oxygen output tube joint are formed, the oxygen of oxygen on valve component inserts mouth and enters, in connection tube enters humidification bottle, connection tube one end and oxygen insert mouth and interlink, the other end is opened on the valve body central lower, be directed downwards, have screw thread on its opening part inwall, connect a humidification fluid pipe with spiral, under the humidification fluid liquid level in the lower end immersion humidification bottle of this humidification fluid pipe, also have screw thread on the inwall of valve component lower end, so that be connected with humidifying bottleneck spiral, there is oxygen metrological service connection tube upper end, and it communicates with connection tube, and connection tube one side has pressure regulator valve to be used to regulate oxygen flow by connection tube; The other end of described oxygen output tube joint is opened on valve body lower portion center one side, and interlinks in the humidification bottle.
Because humidification bottle is contaminated easily, disposable humidication bag is developed out, humidification fluid is sealed in the disposable humidication bag, its oxygen access tube matches with oxygen output tube joint on the valve component, and both connect with pluggable mode, simultaneously the humidification fluid in the humidification bottle are turned, oxygen inserts mouth through oxygen and enters, in connection tube enters empty humidification bottle, enter disposable humidication bag humidifying through the oxygen output tube joint again, insert patient's nasal cavity at last.
Use disposable humidication bag to reduce the probability of medical cross infection largely, but use cost can not be that all patients accept than the humidification bottle height, often needs to change according to patient's requirement in clinical use.
The deficiencies in the prior art part is: in the process that is used alternatingly humidification bottle and disposable humidication bag, still exist the possibility of medical cross infection, show: 1, easy breed bacteria in the Kong humidification bottle.2, valve body lower portion particularly often is exposed to easy breed bacteria in the air in humidification fluid pipe periphery place.3, because oxygen uptake often is intermittence, perhaps, after a patient treatment finished, the oxygen output tube joint on the valve component often was exposed in the air, the easy breed bacteria in oxygen output tube joint.Also bring extra burden to medical worker's sterilization.Need be improved.
(3) summary of the invention:
This utility model aims to provide a kind of oxygen inhalation apparatus of much cleaner improvement structure.
Improve the oxygen inhalation apparatus of structure, comprise superposed valve component, described valve component is advanced oxygen stoichiometry mechanism, pressure regulator valve and oxygen output tube joint and is formed by valve body, oxygen access mouth, connection tube, connection tube one end and oxygen insert mouth and interlink, the other end is opened on the valve body central lower, be directed downwards, have screw thread on the inwall of valve component lower end, there is oxygen metrological service the connection tube upper end, it communicates with connection tube, and connection tube one side has pressure regulator valve to be used to regulate oxygen flow by connection tube; The other end of described oxygen output tube joint is opened on valve body lower portion center one side, it is characterized in that: it also comprises an external screw thread silently, and described external screw thread silently spiral is connected in the valve component lower end.
When using disposable humidication bag, with external screw thread silently spiral be connected in the valve component lower end, at this moment, the oxygen of oxygen on valve component inserts mouth and enters, enter through connection tube, again through external screw thread silently the upper end cavity enter the other end opening of oxygen output tube joint, insert disposable humidication bag humidifying through the oxygen output tube joint, the picking out pipe on disposable humidication bag inserts patient's nasal cavity again.No longer through the humidification bottle of sky, and valve body lower portion humidification fluid pipe periphery place also can not be exposed in the air, reduced the probability of medical cross infection to the full extent.When changing the use humidification bottle, screw off external screw thread silently, screw on humidification bottle, use according to a conventional method to get final product.
Further technical scheme is:
Described external screw thread is connected with a horn mouth that can match with the oxygen output tube joint that has stopper on silently, and described stopper also can match with horn mouth.
Using the gap, horn mouth can be set on the oxygen output tube joint, promptly reduce the probability of oxygen output tube joint medical cross infection.
Further technical scheme is:
Described external screw thread is connected with hook on silently.So that hang disposable humidication bag.
This utility model is simple in structure, and cost is low, uses much cleaner.
(4) description of drawings:
Below with reference to drawings and Examples this utility model is described in further details:
Accompanying drawing 1 is the structural representation of this utility model embodiment.
