Abstract
The invention relates to a degerming and anti-overflowing filter of a medical vacuum extractor, which is composed of two coaxial flap-type casings that are clasped with each other and degerming filter paper encapsulated in the casings, wherein the outsides of the two flap-type casings are respectively provided with an inlet pipe and an air outlet pipe in a coaxial manner. The innovative points of the invention are as follows: an anti-overflow filter element is installed radially and coaxially at one side of the two flap-type casing close to the outlet pipe, and the degerming filter paper is installed on the air inlet surface of the anti-overflow filter element. The invention has scientific and reasonable design, simple structure, good degerming and anti-overflow functions, can perform further safety and security effects on the normal use of the vacuum extractor, and can prolong service life of the vacuum extractor; and simultaneously, the degerming and anti-overflowing filter is an accessory product of the vacuum extractor which is in disposable use, when the degerming and anti-overflowing filter is polluted by liquid, only another degerming and anti-overflowing filter needs to be replaced, therefore, the degerming and anti-overflowing filter is convenient to use and satisfies the high-standard requirement of sanitation, safety and convenience of medical equipment.
Description
Technical field
The invention belongs to medical instruments field, particularly a kind of degerming and anti-overflowing filter of medical vacuum extractor.
Background technology
At present, vacuum extractor is widely used in medical treatment and dirt in patient's breast abdomen is aspirated taking-up in clinical.Existing vacuum extractor mainly is made of cabinet, suction pump, liquid-accumulating bottle, conduit and controller, and controller aspirates position through liquid containing bottle to the patient by the conduit suction side and aspirates.Existing vacuum extractor need be provided with the anti-overflow device usually in liquid containing bottle, to prevent the excessive back of overflowing of stored dirt conduit is produced pollution.And the part at the close cabinet of conduit is equipped with sterilizing filter, this sterilizing filter usually by about the housing of the coaxial mutual fastening of two lobes and the degerming filter element that is packaged in enclosure interior constitute, carry out aseptic filtration by the transcatheter gas of this filter convection current.The existing defective of the vacuum extractor of said structure is: in use when the anti-overflow failure of apparatus, liquid can flow to sterilizing filter through catheter suction, because existing sterilizing filter does not have water-proof function, therefore liquid can directly enter the damage that the suction pump cabinet inside causes the suction pump internal electric behind sterilizing filter, normally uses thereby influence suction pump.Therefore, be badly in need of a kind of sterilizing filter, thereby make vacuum extractor in clinical use, have more safe and reliable anti-overflow function with anti-overflow function.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art; a kind of degerming and anti-overflowing filter of medical vacuum extractor of built-in anti-overflow filter element is provided; its anti-overflow filter element can meet water condense rapidly form self-styled, thereby can effectively stop liquid to pass through, and then protection suction pump internal electric is not damaged.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of degerming and anti-overflowing filter of medical vacuum extractor, by two lobe sandwich type elements of coaxial and mutual fastening and radially be packaged in the intravital degerming filter paper of shell and constitute, coaxial respectively air inlet pipe and the escape pipe of being shaped in the two lobe sandwich type elements outside, it is characterized in that: in two lobe sandwich type elements,, degerming filter paper is installed on this anti-overflow filter element air inlet surface near the radially coaxial installation one anti-overflow filter element of escape pipe one side.
And described anti-overflow filter element outer perimeter is shaped on the ring platform of setting-in degerming filter paper outer rim, and this ring platform is inlaid in the made annular slot of housing medial surface of air inlet pipe one side.
And described anti-overflow filter element is a high-density polyethylene composite material anti-overflow filter element.
Advantage of the present invention and good effect are:
1. this degerming and anti filter is provided with an anti-overflow filter element in housing, this anti-overflow filter element is a high-density polyethylene composite material anti-overflow filter element, under the normal condition, gas carries out filtration sterilization from conduit through this filter, in case the anti-overflow failure of apparatus of vacuum extractor, when liquid enters filter interior from conduit, the anti-overflow filter element of being installed in this filter then can condense rapidly form self-styled, stop liquid inherent filtration device to pass through fully, thereby prevent the damage of liquid the suction pump internal electric.
2. the anti-overflow filter element of this degerming and anti filter is shaped on the ring platform that is flush-mounted in the made annular slot of air inlet pipe one side body medial surface, further guarantees the seal of anti-overflow filter element, thereby improves the anti-overflow function of anti-overflow filter element.
3. design science of the present invention is reasonable, simple in structure, has good degerming and anti-overflow function, can play further safety guarantee effect to the normal use of vacuum extractor, prolongs vacuum extractor service life; This degerming and anti filter is disposable use vacuum extractor accessory product simultaneously, only needs to change another degerming and anti filter and get final product after it is by liquid contamination, and is easy to use, satisfies medical apparatus and instruments health, safety, high standard requirement easily.
Description of drawings

Fig. 2 is the schematic perspective view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of degerming and anti-overflowing filter of medical vacuum extractor, by two lobe sandwich type elements of coaxial and mutual fastening and radially be packaged in its inner degerming filter paper 2 and constitute, two lobe sandwich type element labels are respectively 1,4, at coaxial respectively air inlet pipe 5 and the escape pipe 6 of being shaped on of two lobe sandwich type element outer side edges.Gas feeds from air inlet pipe, discharges from escape pipe behind the degerming filter paper filtering.The innovation part of this degerming and anti filter is: near escape pipe one side one anti-overflow filter element 3 is installed radially in two lobe sandwich type elements.This anti-overflow filter element is the sincere medical apparatus and instruments science and trade company limited (address: No. 467 DaTong Building Room 418, road, the Yellow River, Nankai District, Tianjin City) the anti-overflow filter element made of the high-density polyethylene composite material of Sheng Chaning of Tianjin Kang Hui, the high-density polyethylene composite material of making this anti-overflow filter element is formed by high density polyethylene (HDPE) and sodium carboxymethyl cellulose raw material mixture sintering, it is generally used for liquid in the sealed container, use it among the present invention in the suction pump gas piping, it is not only ventilative to have the filtration sterilization function, also have the water of chance agglomerative self-styled function rapidly simultaneously, have the effect of application mode different from the past.Near the air inlet surface of air inlet pipe one side degerming filter paper is installed at this anti-overflow filter element.Anti-overflow filter element outer perimeter is shaped on the ring platform 7 of setting-in degerming filter paper outer rim, and this ring platform is flush-mounted in the made annular slot of air inlet pipe one side body medial surface, with its sealing of further enhancing, prevents that liquid from passing through from anti-overflow filter element periphery.
