Abstract
A medical air pump mainly comprises a casing, a pump body, an energy storage pressure rod, an electromagnet and a controller, wherein the pump body comprises a pump bag, an air chamber, an air inlet and an air outlet. The lower end of the pressure rod is fixed with the bottom of the machine shell, the upper end of the pressure rod is provided with a permanent magnet, and the electromagnet is fixed in the machine shell through screws. The controller consists of a switch, a diode and a potentiometer, all parts are assembled in the shell, the output air pressure value or the air flow rate of the air pump can be continuously changed between 0 and the maximum value as required through the magnetic force generated by the controllable electromagnet, and the air pump is convenient to use, simple in structure and low in price.
Description
This utility model relates to a kind of medical air pump of being made up of casing, the pump housing, energy storage press rods, electric magnet and controller.
Domestic medical air pump imported product is more at present, its complex structure, and volume is big, and is on the high side, and is difficult to buy.
The purpose of this utility model is in order to provide a kind of volume little, simple in structure, low-cost small-sized medical air pump.
This medical air pump is by casing, the pump housing, the energy storage press rods, electric magnet and controller are formed, it is characterized in that the pump housing is by the pump capsule, air chamber, air inlet and air vent are formed, air chamber is fixed on the casing with screw, in air chamber, be provided with two check valves, the downside of air chamber has an air vent, the upside of air chamber has an air inlet that communicates with casing, air bag is fixed by bolts on the press rods, the opposite side of air bag matches with the side of air chamber, the lower end and the bottom of shell of press rods fix, permanent magnet is equipped with in upper end in press rods, electric magnet is fixed in the casing with screw, makes between electric magnet and the permanent magnet to have certain interval, and controller is by switch, diode and potentiometer are formed, each assembly is contained in the casing, one end of switch is connected with an end of power supply, and the other end of switch and the positive pole of diode join, and the negative pole of diode is connected with an end of potentiometer, the other end of potentiometer is connected with magnet spool, and the other end and the power supply of electromagnet coil join.
Now in conjunction with the accompanying drawings this utility model being done one describes in detail.
The overall structure sketch map of this medical air pump of Fig. 1 (rearview (folding bottom) }.
The structure and the gas circuit sketch map of the pump housing air chamber of this medical air pump of Fig. 2.
The control electrical schematic diagram of this medical air pump of Fig. 3.
The operation principle sketch map of this medical air pump of Fig. 4 during as suction pumps.
This utility model is the rectangular body shape shown in (Fig. 1), casing (1) is moulded casting for plastics and made.Its structure is the pump housing, energy storage press rods, electric magnet and controller four major parts.The pump housing is made up of elastomeric pump capsule (13), air chamber (12), air inlet (11), air vent (14).Pump capsule (13) is pressed on air chamber (12) one ends, and air vent (14) is an one with air chamber (12), and air inlet (11) is an one with casing (1), and the structure and the gas circuit of air chamber (12) are seen Fig. 2.Indoor one-way cock (15) and (16) of being provided with, air chamber (12) is fixed on the casing (1) with screw.The energy storage press rods is made up of beam type press rods (2) and permanent magnet (3), press rods one end is fixed on the casing (1) with screw, one end is stained with permanent magnet (3), the middle part is fixedly connected with the screw and the pump housing, electric magnet is made up of electromagnet coil (5) and (7) unshakable in one's determination, electromagnet coil (5) and is fixed on the casing (1) with screw on unshakable in one's determination (7).Has certain interval between permanent magnet (3) and the electric magnet.Controller is made up of single-pole double-throw switch (SPDT) (10), diode (9), potentiometer (8).Dial to diode (9) one ends when switch (10), regulate for low gear by potentiometer (8), dial to potentiometer (8) one ends when switch (10), regulate for top grade, it is controlled electric principle and sees Fig. 3, and controller is separately fixed on the casing (1).
The medical air pump of this utility model, adopt civil power (220V50Hz) power supply, civil power is added on the electric magnet by attaching plug (4) and power line (6) via controller, formed alternating magnetic field, permanent magnet (3) on the electromagnetic attracting force press rods (2) that is produced, press rods (2) is moved back and forth, driving pump capsule (13), impel air chamber (12) inflation or aerofluxus, press rods (2) is the accumulation energy type structure, make by elastic sheet metal, its initial position design makes pump capsule (13) be in almost completely compressed state, the air inlet of the pump housing (11) is when communicating with atmosphere, air vent (14) pressurization aerofluxus, air pump is worked by malleation inflation mode, the air vent of the pump housing (14) is when communicating with atmosphere, air inlet (11) negative pressure ventilation, air pump is pressed the work of negative inspiratory pressure mode shown in (Fig. 2), toggle switch (10) or adjustment potentiometer (8), can in the scope of 0-220V, change the voltage that adds on the electromagnet coil (5), thereby the inflation pressure values of control air pump or gettering rate are shown in (Fig. 3).
This utility model adopts different gas circuit connected modes according to different application requirements, can be used separately as malleation inflator pump or negative inspiratory pressure pump.Install imbibition bottle with sucker (17) adnexa additional, through design air pump (18) and liquid (19) are linked up, can make the negative pressure suction pumps shown in (Fig. 4), its inflation pressure values or gettering rate can 0 and maximum between regulate continuously, it is simple in structure, easy to use, volume is little, low price, is a kind of small-sized medical air pump.
