Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
Referring to Fig. 1, a kind of anti-blockage stomach tube 10, including tube body 100, side pipe 200 and filter device 300, tube body 100 are used
In extracting foreign matter and injection liquid in stomach, side pipe 200 is for injecting gas, and filter device 300 is for being filtered foreign matter.
Referring to Figure 2 together, specifically, tube body 100 includes inner tube 110 and outer tube 120.The both ends of inner tube 110 are respectively
Open end 112 and closed end 113.Outer tube 120 is sheathed in inner tube 110, and the both ends of outer tube 120 are connected with the outer wall of inner tube 110
It connects, forms accommodating chamber 400 between outer tube 120 and inner tube 110.The closed end 113 of inner tube 110 is stretched out outside outer tube 120, inner tube 110
Closed end 113 offer foreign matter hole 111, the inner cavity of inner tube 110 is connected by foreign matter hole 111 with the external world.The number in foreign matter hole 111
Amount is multiple, circumferential direction interval setting of multiple foreign matter holes 111 along closed end 113.
The closed end 113 of inner tube 110 is for extending into the stomach of patient, oral cavity or nose of the open end 112 via patient
Outside chamber lead body.Medical staff can by open end 112 into inner tube 110 injection of medicine and food etc., drug and food according to
It is secondary to be entered in patient's stomach by the inner cavity and foreign matter hole 111 of inner tube 110.In one embodiment, in order to avoid inner tube 110 is dirty
Dye, anti-blockage stomach tube 10 further include plugging block 114, and plugging block 114 is inserted in the interior intracavitary of inner tube 110 by open end 112, with
The open end 112 of inner tube 110 is blocked.The end face of the closed end 113 of inner tube 110 is spherical surface, to prevent closed end 113 from extending into
Patient is abraded during in patient's stomach.
Side pipe 200 is set on the side wall of outer tube 120, and side pipe 200 is connected with accommodating chamber 400.It is arranged on side pipe 200
There are plug 210 and pressure gauge 220.Plug 210 is set to the one end of side pipe 200 far from outer tube 120, and plug 210 is inserted in side pipe
To block side pipe 200 in 200, for preventing the gas in side pipe 200 and accommodating chamber 400 from leaking.Pressure gauge 220 is set to side pipe
On 200, the side wall that pressure gauge 220 passes through side pipe 200 is extend into side pipe 200.Pressure gauge 220 is used to test in accommodating chamber 400
The size of gas pressure.Certainly, when injecting in accommodating chamber 400 is liquid, pressure gauge 220 can also be used to test fluid pressure
Size.
Please generally refering to Fig. 2 and Fig. 3, filter device 300 includes piston 310 and flexible filter net 320, and piston 310 can be slided
It is dynamic to be sheathed in inner tube 110, and piston 310 seals accommodating chamber 400.One end of flexible filter net 320 is set to inner tube 110
The other end of closed end 113, flexible filter net 320 is connected with piston 310, and flexible filter net 320 can cover foreign matter hole
111.The movement of piston 310 can make flexible filter net 320 deform, with change flexible filter net 320 filter opening 321 shape and
Size.In one embodiment, flexible filter net 320 be it is cylindric, flexible filter net 320 is sheathed on closed end 113, flexible mistake
The other end of strainer 320 is connected with the week edge of piston 310.
It is specifically, soft when piston 310 does not apply active force to flexible filter net 320 also referring to Fig. 1 and Fig. 4
Property filter screen 320 is in rounding state and is in the form of a column.When the shapes and sizes for the filter opening 321 for needing to change flexible filter net 320
When, charger is connected with side pipe 200, and gas is then injected into accommodating chamber 400, and the pressure in accommodating chamber 400 increases therewith
Add, thus push piston 310 mobile to the direction close to closed end 113,320 forced compression of flexible filter net, flexible filter net
320 become spherical from column, and the surface area of flexible filter net 320 increases, the aperture of the filter opening 321 of flexible filter net 320 with
Become larger.In use, the size that can according to need filtering foreign matter, determines the gas flow being filled with, to adapt to filter
Different size of foreign matter demand.
The application method of above-mentioned anti-blockage stomach tube 10 specifically:
The closed end 113 of anti-blockage stomach tube 10 is extend into stomach, outside 112 via intranasal application of open end or oral cavity lead body.
When injecting medical fluid or food in needing to stomach, the plugging block 114 in inner tube 110 is extracted, medical staff passes through open end 112
Injection of medicine and food etc. into inner tube 110, drug and food pass sequentially through the inner cavity of inner tube 110 and foreign matter hole 111 enters
In patient's stomach.
When needing to extract the foreign matter in stomach, the plug 210 of side pipe 200 is removed, through side pipe 200 into accommodating chamber 400
It is filled with gas.Pressure in accommodating chamber 400 increases, so that piston 310 is driven to move, side of the piston 310 to close closed end 113
To movement, 320 forced compression of flexible filter net, flexible filter net 320 expands outwardly spherical in shape, 320 filter opening 321 of flexible filter net
Aperture become larger.Pressure gauge 220 is observed, when pressure reaches reservation value, the aperture of filter opening 321 reaches preset value.Then, stop
Pressurization, and plug 210 is covered into back side pipe 200.When passing through 112 suck foreign matter of open end, the work of foreign matter in stomach in attraction
It is successively entered in the inner cavity of inner tube 110 after the filter opening 321 of flexible filter net 320 and foreign matter hole 111 under.
In use, when filter opening 321 is blocked, by injecting or aspirating the gas in accommodating chamber 400, thus
Change the size of gas pressure in accommodating chamber 400, at this moment piston 310 is just as the variation of pressure moves up and down, flexible filter net
The size of 320 filter openings 321 changes therewith, and the foreign matter blocked on filter opening 321 is just disposed of.
Above-mentioned anti-blockage stomach tube 10, tube body 100 are used to extract foreign matter in stomach and injection of medicine or food, filter device
300 for filtering foreign matter.It in use, can be by adjusting the size of pressure in accommodating chamber 400, to change filter opening
321 size is to adapt to different size of foreign matter.It is through filter opening by the foreign matter that foreign matter hole enters in 110 inner cavity of inner tube
321 is filtered, so as to avoid foreign matters from being blocked foreign matter hole 111, can be avoided and needs repeatedly because foreign matter hole 111 is blocked
The problem of cleaning stomach tube or replacement stomach tube, to mitigate the pain of patient and reduce the workload of medical care person.When 321 quilt of filter opening
When foreign matters from being blocked, by injecting or aspirating the gas in accommodating chamber 400, change the size of pressure in accommodating chamber 400, to make
Piston 310 is moved up and down with the variation of pressure, and the size of 320 filter opening of flexible filter net also changes therewith, is blocked on filter opening 321
Foreign matter be just disposed of.This anti-blockage stomach tube 10 can effectively avoid foreign matter hole 111 from being blocked, to mitigate patient's
Pain and the workload for reducing medical care person.
