Abstract
The utility model discloses a Press discharge valve which belongs to medical appliances, and the press discharge valve is the inflation and the discharge devices of hemomanometers, etc. The utility model is characterized in that an air needle cap, an air needle, a piston and a small hole are integrated; turn knob type is changed into the press type to discharge the air; the method of the air discharge which is freely controlled is formed under the action of the two counterweight of press fingers and an internal pressure spring, which causes the measurement of pressure to be exact, saves the time for saving patients and increases the efficacy of use. The utility model has the advantages of convenient operation and high practicality.
Description
Belonging to medical apparatus and instruments by the vent valve of calming the anger, is the inflating of sphygomanometer etc., means of deflation.
The vent valve of this area is to adopt knob at present.Need be with two finger control handles during operation, exhaust velocity depends on the up time of knob and the control of turn counterclockwise.Therefore be not easy very much support and hold exhaust velocity.Yet exhaust velocity directly affects the observation of blood pressure index.Therefore, easily cause pressure measurement inaccurate, incur loss through delay the time that gives emergency treatment to a patient.
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of pressing type vent valve of providing is controlled exhaust velocity effectively, makes pressure measurement accurate, saves the time that gives emergency treatment to a patient, and improves to use and renders a service handled easily.
Invention structure (seeing figure)
The purpose of this utility model is so to realize: in sleeve pipe, the air tube of piston and hollow is one, and is anchored on the air tube medicated cap.Aperture on the air tube (when depressing cut of file position) communicates steam vent and air flue.The air cushion pad between shelves needle ring and piston in case shelves pin gas leakage.In use, air flue is gone in the air inlet of air bag interface portion, and piston and shelves needle ring are close on the air cushion, and air tight.When pushing cut of file portion, air tube, piston move down steam vent, aperture are communicated with air flue, and the gas in the air flue is discharged through " new air flue " that this communicates.Thereby finish once-through operation.Because aperture is vertically to arrange, so press down the degree of depth difference of air tube, the tolerance of discharge is also different.Be convenient to so very much manual venting.
Owing to adopt said method and structure, make deflation course use hand control at an easy rate, the bimanualness of correcting one's mistakes is an one-handed performance, perhaps changes to refer to be operating as singly to refer to operation more.
Accompanying drawing is the sketch map of pressing type vent valve, wherein:
1, air tube medicated cap 8, air cushion
2, stage clip 9, piston
3, air tube 10, spiral interface
4, steam vent 11, gas are chewed
5, sleeve pipe 12, air flue
6, aperture 13, air bag interface
7, retaining needle ring 14, transverse tube
15, the cut of file
Most preferred embodiment
The all available chromium plating ferrum of whole pressing type air valve is made.The top has the oblate type air tube medicated cap (1) of the cut of file (15), the air tube of hollow (3), the T-shape structure that piston (9), aperture (6) air cushion (8) are combined into one jointly, and sleeve pipe (5) and transverse tube (14) are combined into one by spiral interface (10) and (comprise the structure of falling the T-shape that air flue (12), shelves needle ring (7), gas are chewed (11), air bag interface (13).Shelves needle rings (7) are that a horizontal shape is fixed on the ring-like oblate body in the sleeve pipe (5).Its aperture is suitable with the air tube size, with can up and down exceeding; The outer rim of piston (9) and telescopic inwall size also can up and down exceeding with piston.The effect of so just reliable stage clip (2) and air cushion (8) does not make the gas of air flue (12) at will discharge.But control exhaust velocity by the firmly size of pushing air tube medicated cap (1), realize measuring accurate and effective, convenient, operation, the saving rescue time of blood pressure.
Claims (6)
1, the formation of pressing type vent valve is in sleeve pipe, it is characterized in that the air tube of piston and hollow is one, and is anchored on the air tube medicated cap, and the aperture on the air tube can make steam vent and air flue communicate, and the air cushion pad is between shelves needle ring and piston.
2, vent valve according to claim 1 is characterized in that air tube medicated cap (1) top is carved with the cut of file (15).
3, vent valve according to claim 1 is characterized in that air tube (3) middle part has several apertures (6), and the bottom is piston (9) along continuing.
4, vent valve according to claim 1 is characterized in that aperture (6) is several very little pin holes, and its inside is interconnected.
5, vent valve according to claim 1 is characterized in that piston (9) is flat, is placed in the sleeve pipe (5), under the shelves needle rings (7).
6, vent valve according to claim 1 is characterized in that air cushion (8) is placed between piston (9) and the shelves needle ring, with anti-gas-leak.
