Abstract
The utility model relates to an adjustable oxygen supply switch, which is an improved medical anesthesia machine part. One end of a base (3) is provided with inner screw threads (10) matched with an oxygen supply press-button seat (7) of the anesthesia machine. The utility model is characterized in that the other end of the base (3) is provided with inner screw threads (5) matched with an adjusting handle (2); the center of the adjusting handle is provided with a through hole; the through hole forms a clearance fit with a polished rod of a press-button (1); the rod end of the press-button (1) forms a screw thread fit with a link stopper (4). When oxygen supply quantity needs adjusting in operation, the press-button can be released after the adjusting handle (2) is rotated; an operator does not need to always contact the press-button (9) with the hand.
Description
This utility model is the medical anesthetic machine parts that improved.
When giving patient's surgery anesthesia oxygen supply, the control method of oxygen-supplying amount size is as follows, referring to Fig. 1 double dot dash line part, need medical personnel to press button (9) and observe the oxygen supply Pressure gauge, dynamics is pressed in control makes oxygen supply pressure reach desired value, and like this, these medical personnel can not loose one's grip, otherwise back-moving spring (6) will make button (9) reset.The aforesaid operations mode often needs a people to regulate oxygen-supplying amount in operation process, and another people controls face shield and contacts with the patient, one man operation inconvenience, and two people operation then is not easy to operation.
The purpose of this utility model is improved the oxygen supply control knob that has anesthetic machine now, and design one cover attachment device makes the oxygen supply switch become the adjustable control structure, and a people can finish the operation oxygen-supply operation easily.
For achieving the above object, this utility model adopts following technical scheme: screwing off anesthetic machine oxygen supply button cover need not, base (3) one ends have the female thread (10) that cooperates with anesthetic machine oxygen supply push-button socket (7), base (3) other end is the female thread (5) that cooperates with adjusting tap (2), adjusting tap (2) center is a through hole, this through hole and button (1) polished rod matched in clearance, button (1) rod end and a link stopper (4) threaded engagement.
By such scheme as seen, rotation adjusting tap (2) can make button (1) withstand button (9), thereby replaces the control of people's dynamics by mechanical whorl, when needing to transfer oxygen-supplying amount in the operation, can loose one's grip after only need rotating adjusting tap (2), need not hands and contacts all the time.
Description of drawings:
Fig. 1, example structure sketch map;
The A-A view of Fig. 2, Fig. 1.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof, base (3) one ends are spun on the push-button socket of taking away after anesthetic machine oxygen supply button overlaps (7), promptly be fixed on the anesthetic machine control panel (8), other end outer rim one all annular knurls, adjusting tap (2) one end outer rim annular knurls, the external screw thread of the other end and female thread (10) are reverse, screw off the rotatable link stopper of adjusting tap (2) (4) and regulate button (1) nargin on axial adjusting tap (2) through hole in, oxygen-supplying amount only depends on adjusting tap (2) control during no nargin, oxygen-supplying amount also can be pressed button (1) and do the interior adjusting among a small circle of nargin stroke when nargin was arranged, the bar of button (1) is grown up long in the hole of adjusting tap (2) through hole, link stopper (4) external diameter greater than adjusting tap (2) through-hole aperture less than female thread (5) diameter.
Claims (2)
1, adjustable oxygen supply switch, base (3) one ends have the female thread (10) that cooperates with anesthetic machine oxygen supply push-button socket (7), it is characterized in that: base (3) other end is the female thread (5) that cooperates with adjusting tap (2), adjusting tap (2) center is a through hole, this through hole and button (1) polished rod matched in clearance, button (1) rod end and a link stopper (4) threaded engagement.
2, according to the described adjustable oxygen supply switch of claim 1, it is characterized in that: the female thread (5) at base (3) two ends is opposite with (10) rotation direction, the bar of button (1) is grown up long in the hole of adjusting tap (2) through hole, link stopper (4) external diameter is greater than adjusting tap (2) through-hole aperture, less than female thread (5) diameter.
