Abstract
The invention relates to a simple sputum aspirator. A main body of the simple sputum aspirator comprises a negative pressure ball at the upper portion, a sputum storage device in the middle, a sputum aspiration tube at the lower portion and the like. The negative pressure ball is a device capable of generating aspiration negative pressure; the shape and the materials of the negative pressure ball are not limited; and a spring bringing convenience to resetting of the negative pressure ball can be arranged inside the negative pressure ball. The sputum storage device in the middle is a transparent container, scales are arranged on the wall, and therefore the nature and the collecting amount of collected sputum can be observed. A function cover is arranged at the upper end of the liquid storage device; and an air inlet one-way valve, an air outlet one-way valve, a backflow-prevention channel and the like are arranged on the function cover. The function cover is in tight connection with the negative pressure ball and the sputum storage device. Scales are arranged on the sputum aspiration tube at the lower portion, so that the insertion depth can be conveniently observed and judged. Aspiration heads at the front end are spherical aspiration heads, a plurality of long-strip-shaped aspiration holes or aspiration heads in other shapes. The back portion of the sputum aspiration tube is inserted into the sputum storage device, and a backflow-prevention one-way valve is arranged at the tail end of the sputum aspiration tube. The sputum aspiration tube can be sleeved with an umbrella-type protection cover, so that contamination of bucking objects to medical workers is avoided.
Description
Technical field
The present invention relates to a kind of simple type sputum-sucking device.
Background technology
After neonate birth, in its oral cavity and throat, amniotic fluid and sputum can be adhered to, be prevention asphyxia of newborn, in delivery room or operating room domestic demand, conventional attraction is needed to newborn respiration road.Existing suction sputum instrument is for connecing survivor's mouth suction sputum aspirator, suction pump sputum aspirator tube, rubber pipette bulb, piston type sputum aspirator etc.Mouthful suction sputum aspirator, needs medical personnel with mouth by the sputum sucking-off of sputum aspirator tube by patient, sputum may be caused like this to enter in the mouth of medical personnel, there is safe and sanitary hidden danger.Suction pump sputum aspirator tube needs electronic attraction, and its negative pressure is wayward, easily produces newborn respiration road mucosa injury.Rubber pipette bulb can not attract continuously, and when being directly used in suction sputum, sputum directly enters negative pressure and inhales ball, and each attraction, in operating process, all needs first to be extruded by sputum later, and inhales the cleaning also very inconvenience of ball for negative pressure.Design that all kinds of piston type sputum aspirator has is complicated, and some volumes are excessive not portable, the defect such as effort when pulling when not using for a long time.
Summary of the invention
The object of the invention is to design a kind of simple type sputum-sucking device, operation of being conveniently grown up, only need one hand can complete the airtight attraction of controlled persistence negative pressure.In suction sputum process, can guarantee that sputum is without leaking, and avoids cross infection.And the degree of depth and sputum collecting amount of observing sputum aspirator tube insertion can be understood, medical hidden danger is dropped to minimum.Can be used as neonate and application such as adult sputum aspirator, nose sucking device, pus and blood suction pump etc., obstetrics, department of pediatrics, internal medicine, emergency center and standing in family can be widely used in.
Specific implementation of the present invention is: the main body of simple type sputum-sucking device comprises the negative pressure ball of upper part, the liquid reservoir of mid portion, the sputum aspirator tube etc. of lower part.Negative pressure ball is that a kind of can generation attracts the device of negative pressure, and its shape and material are not limit, inside one can be had to contribute to spring that negative pressure ball resets.The liquid reservoir of mid portion is a transparent vessel, and its shape is not limit.Wall there is scale, the sputum character that observable is collected and collecting amount.The upper end of liquid reservoir is a functional cover, has breather check valve, outgassing nonreturn valve and antireflux passage etc. above.This functional cover and negative pressure ball, liquid reservoir are in being tightly connected.Breather check valve, outgassing nonreturn valve and antireflux passage also can on other positions of device.The sputum aspirator tube of lower part with scale, to facilitate observe and decide insertion depth.The sucking head of front end is spherical sucking head, several strip suction hole or the sucking head for other shapes.The rear section of sputum aspirator tube is inserted in liquid reservoir, and end has the unidirectional valve of antireflux.Also can overlap a umbrella shape protective cover on sputum aspirator tube, prevent from choking and cough thing being infected with medical personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention; Wherein, 1-negative pressure ball, 2-pick up the ears, 3-spring, 4-outgassing nonreturn valve, 5-breather check valve, 6-antireflux passage, 7-liquid reservoir, 8-sputum aspirator tube, 9-functional cover, 10-unidirectional valve.
Detailed description of the invention
During per os suction sputum, operator's single-hand handling & sputum aspirator, inserts the sputum aspirator tube of sputum aspirator bottom in neonate oral cavity, and instructs insertion depth with the scale on sputum aspirator tube.Thumb presses lower negative pressure ball, and the gas now in negative pressure ball is discharged by outgassing nonreturn valve, gas outlet.Malleation now in negative pressure ball makes breather check valve automatically close.Unclamp thumb, negative pressure ball resiles, and now, outgassing nonreturn valve is closed automatically, and breather check valve is automatic opening under the negative pressure of negative pressure ball, and the gas in liquid reservoir is inhaled into negative pressure ball by air inlet and antireflux passage, produces negative pressure in liquid reservoir.And so forth, continual negative pressure is just had in liquid reservoir.Sputum is entered in liquid reservoir by sputum aspirator tube.When negative pressure in liquid reservoir disappears, the unidirectional valve of sputum aspirator tube end is closed automatically, prevents sputum adverse current.Attract complete, extract sputum aspirator tube and namely complete the airtight suction sputum operation of control persistence negative pressure.In suction sputum process, can guarantee that sputum is without leaking, and avoids cross infection.And the degree of depth and sputum collecting amount of observing sputum aspirator tube insertion can be understood, can medical hidden danger be dropped to minimum.
Attract can to equally any patient's sputums of section office such as internal medicine, surgery, Pediatrics Department and wound pus and blood.Also can be used as nose sucking device to apply in the family.
This simple type sputum-sucking device is a kind of sustainability negative pressure suction sputum, inhales the medical apparatus of the liquid such as saliva, suction pus and blood.Only need one hand to operate, do not limit by environmental condition, do not consume energy, noiseless, lightweight be inexpensive, easy to carry, safe and reliable, practical.Be applicable to the attraction of neonate pars oralis pharyngis amniotic fluid, field condition first aid, home care etc., adult and child can use.
The foregoing is only preferred embodiment of the present invention, is not restriction the present invention, all do in purport of the present invention and principle equivalent replacement, improvement, assembly increase and decrease, title replacing etc., within the scope all belonging to rights protection of the present invention.
