Purpose of design of the present utility model is exactly the deficiency that exists at above-mentioned technology, develop a kind of simple and practical tubulose check valve of not only being convenient to open but also can compare tight closing, and omit unnecessary structure, make single unit system be tending towards simplifying, be suitable for the portable medical suction device of sticky liquid suction.

Another purpose of design of the present utility model is on the said structure basis, sets up the back work capsule for strengthening vacuum suction.

The technical pattern of portable medical suction device mainly is made up of suction catheter, work capsule, connection tube, collecting chamber etc.Characteristics are to have the pipe joint and the arrival end of work capsule to connect firmly, and the external part and the suction catheter of pipe joint overlap admittedly, and the inserting end of pipe joint and tubulose check valve overlap admittedly; The tubulose check valve is the section of a pipe of endcapped, at the seam of drawing that is provided with some walls pipe week; Other has the pipe joint and the port of export of work capsule to connect firmly, and tube joint and connection tube overlap admittedly, and the far-end of connection tube puts in the plastic bag, and in the rearward end of this pipe joint or at the far-end of connection tube the tubulose check valve is housed also.

This technical pattern also comprises following content: the tubulose check valve that communicates with suction catheter places within the work capsule arrival end, and the tubulose check valve is provided with, and wall is drawn the periphery of seam and there is the gap in the capsule arrival end inwall of working.The work capsule adopts tandem work capsule, can make monoblock type tandem working capsule or make the formula tandem working capsule that is connected.Set up the other back work capsule that connects, put in work capsule, the other end by an end of transition conduit and be provided with the tubulose check valve and connect firmly with the arrival end of back work capsule, the port of export of back work capsule is associated with another tubulose check valve outward.On work capsule arrival end, be provided with the elastic force pressing bar that the tubulose check valve of can conflicting makes it to be out of shape.

Portable medical suction device according to above-mentioned technical pattern, has following advantage successively: when the heavy patient has thick sputum to block venturi, earlier with the close thick sputum place of suction catheter opening, use hands pinching work capsule simultaneously, air is barotropic state in the capsule, the tubulose check valve at the arrival end place of capsule is because of the even compression of positive pressure air, make the tube wall of check valve be contraction state, naturally compress and stroke seam of sealed tube on week, the port of export of capsule is because of linking with another tubulose check valve, because the transmission of air positive pressure power, this check valve tube wall is propelled the price of to be expanded, drawing on pipe week stitched because of distortion, spreading becomes breach, makes that air enters plastic bag by this breach in the capsule, or propels the price of plastic bag or leak from the connection place of plastic bag and discharge to atmosphere.After staff unclamped the work capsule, the work capsule is the elastic return original state on one's own account, and be negative pressure state in the capsule this moment, and the tubulose check valve that the port of export of capsule links is closed because of the external atmosphere pressure effect bounces back down and drawn seam; The tubulose check valve at the entrance point place of capsule, open by suction catheter because of external atmosphere pressure and day to act in the pipe of this valve, make this valve swollenly rise, draw seam and form breach, simultaneously because the vacuum suction in the capsule makes thick sputum class fluid enter the work capsule by suction catheter, check valve breach; When pinching work capsule once more, the entrance point closed check valve, port of export one-way valve opens, thick sputum class fluid flows to plastic bag with air in the capsule and collects; When unclamping the work capsule once more, again with thick sputum class fluid inspiration work capsule in the disease population; Repeat to pinch, behind the pine work capsule several times, expectorant class fluid can be all from disease population sucking-off to plastic bag collect.This tubulose check valve is when its extraneous air is malleation, and the valve pipe shrinks evenly, draws seam and closes tight; When externally air was negative pressure, valve body is swollen to rise evenly, it is rapid to draw the seam breach, was a kind of very simple, effectively the single effect valve.This tubulose check valve can be made very short one section, and directly be hidden within the work capsule entrance point, thick sputum class fluid can be by check valve the gap of drawing seam breach, the work capsule arrival end inwall of flowing through, enter the work capsule, therefore during pinching work capsule, can not touch the tubulose check valve, make work more reliable.After adopting tandem work capsule or side to connect the back work capsule when work these additional work capsules of pinching simultaneously, the vacuum suction ability is multiplied, this is to adapting to different patients (example adult or fetus), attracting differently to block fluids (routine thick sputum or particle meconium), accelerate attraction speed etc., can distinguish to select for use to have positive effect.After work capsule arrival end is provided with elastic force pressing bar, in case the suction catheter opening part stops up because of the grain piece, need only pressing pressing bar, make tubulose check valve local deformation, draw seam nature generation breach, blow to suction catheter by pinching work capsule, the grain piece is blown out from the suction catheter opening, and this is favourable to getting rid of the suction catheter plugging fault and cleaning suction catheter.
