Abstract
The utility model discloses a double-cavity stomach tube with a filter. The double-cavity stomach tube with the filter comprises a main tube body with the lower end closed. The main tube body is provided with scales for identifying the inserting depth. An inner cavity of the main tube body is divided into two tube cavities through a diaphragm. The two tube cavities at the upper end of the main tube body are diverged to form two tubes. The two tube cavities are communicated at the lower end of the main tube body to form a common cavity. A side wall of the common cavity is provided with a side hole. Tube connectors are respectively arranged on the two tubes diverged. A filter which can be closed is arranged on any one of the tube connectors. The double-cavity stomach tube with the filter has the advantages of effectively preventing germs and particles in air from entering bodies of patients, preventing infections, being convenient to use, saving raw materials, and lowering production cost.
Description
Technical field
This utility model relates to a kind of medical auxiliary appliance, a kind of specifically double-cavity stomach tube that has filter.
Background technology
Stomach tube is used for extracting gastric juice as a kind of medical auxiliary appliance more, also uses in the dealing stomach to inject liquid and as the patient necessary food and nutrition is provided.A kind of double-cavity stomach tube with Y-joint is proposed among the Chinese patent CN 201220036Y; Comprise the main pipe; Said main pipe is provided with the scale of sign insertion depth, and said main pipe's inner chamber is divided into main tube cavity and auxiliary tube chamber by barrier film, and main tube cavity and auxiliary tube chamber communicate at main pipe's head; Form common cavity, have side opening on the sidewall of said common cavity.Said main pipe's upper end is plugged with Y-joint; Said Y-joint includes is responsible for joint and auxiliary tube joint; The intravital main tube cavity of the said person in charge's joint and the said person in charge is pegged graft, and said auxiliary tube joint is pegged graft with being responsible for intravital auxiliary tube chamber, and said person in charge's joint and auxiliary tube joint close up at splicing position; The end of being responsible for joint and auxiliary tube joint is the working end, is furnished with first stopper on the working end of said auxiliary tube joint.This utility model is made improvement on the basis of original stomach tube, for making and use brings certain convenience, but the same with original stomach tube, in use all can not avoid in airborne pathogenic bacteria and the granule entering body, thereby cause infection.
The utility model content
This utility model technical issues that need to address provide the double-cavity stomach tube of a kind of prevention infection, band filter easy to use.
For solving the problems of the technologies described above, the technical scheme that this utility model adopted is:
Be with the double-cavity stomach tube of filter, comprise the main pipe of lower end closed, said main pipe is provided with the scale of sign insertion depth; Said main pipe's inner chamber is divided into two tube chambers by barrier film; Two tube chambers of said main pipe's upper end are branched into two pipes, and two tube chambers communicate in main pipe's lower end and form common cavity, have side opening on the sidewall of said common cavity; On two pipes of said bifurcated pipe joint is set respectively, wherein any pipe joint is provided with the filter that can seal.
The further improvement of this utility model is: the oviduct that said pipe joint is set to open wide the upper end or with the oviduct of female luer.
The further improvement of this utility model is: said filter is the politef filter membrane, and the outer end of politef filter membrane is furnished with stopper.
The further improvement of this utility model is: two pipes of said main pipe's upper end are branched into the Y type.
Because the technological progress of having adopted technique scheme, this utility model to obtain is:
This utility model design has the double-cavity stomach tube of filter; The filter membrane preferably polytetrafluoroethylene complex polypropylene of said filter; Can prevent effectively that airborne pathogenic bacteria and granule from getting in patient's body, prevention infection, set filter is transposition between two pipes of main pipe's bifurcated again; Be difficult in the tube chamber stopping up, easy to use; This in addition design has also reduced the necessary expander technology of common stomach tube, and conservation reduces production costs.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Wherein, 1, the main pipe, 2, common cavity, 3, side opening, 4, barrier film, 6, filter, 7, stopper, 8, pipe joint.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is explained further details:
The double-cavity stomach tube of band filter, as shown in Figure 1, comprise that the main pipe 1 of lower end closed, said main pipe 1 are provided with the scale of sign insertion depth.Said main pipe's 1 inner chamber is divided into two tube chambers by barrier film 4, and two tube chambers of said main pipe's 1 upper end are branched into two pipes, and two pipes are branched into the Y type.Two tube chambers communicate in main pipe's lower end and form common cavity 2, have side opening 3 on the sidewall of said common cavity 2, on two pipes of said bifurcated pipe joint 8 are set respectively.Said pipe joint 8 is set to and the unlimited oviduct in the direct agglutinating upper end of tube chamber, also can be the oviduct of band female luer, and oviduct is directly connected attraction system, also can connect attraction system through the oviduct of female luer.Said any pipe joint is provided with the filter 6 that can seal.The filter membrane preferably polytetrafluoroethylene complex polypropylene of said filter 6.The end of said filter 6 and pipe joint 8 is the working end, and the working end of filter is furnished with stopper 7.
The groundwork principle of this utility model is: when the tube chamber of the pipe joint that filter is not set is connected with the continuous negative pressure suction system, the stopper of filter outer end is opened can force to attract; When this tube chamber is connected with negative pressure ball, on the plug with the filter outer end,, be in the air cavity of a sealing because stomach tube no longer communicates with atmosphere, so can keep negative pressure, can use negative pressure ball to attract.Therefore can force switching between the attraction of attraction and negative pressure ball easily through the stopper on the plug filter.When this tube chamber takes place to stop up; Can filter be exchanged on another tube chamber; Connect negative pressure system through another tube chamber and attract, after on the plug of filter outer end, can the pipe joint that filter is not set be connected negative pressure ball and attract; Reverse attraction can attract out with the tamper on the side opening that is jammed in common tube chamber, to keep unimpeded between tube chamber and the stomach.
