Description
Technical field:
The present invention relates to a kind of medical catheter for perfusion or discharge, is a kind ofly to be used for colonic dialysis or to irritate the filling-discharging duct that discharge opeing bodies use through intestinal treatment or perfusion fluid or other lumen pores of human body.
Background technology:
The inventor's Chinese patent 89108493 and 00124342.X disclose two kinds of filling-discharging ducts respectively, the former is the filling-discharging duct that the liquid injection pipe tube wall is provided with gas injection system in the human body, and the latter is that discharging tube (or claiming the chamber door) tube wall is provided with the filling-discharging duct of gas injection system.Gas injection system comprises and places air bag in the forward body of liquid injection pipe in the human body, and what is communicated with air bag in the body imbeds air injection pipe in the body in the liquid injection pipe tube wall, also includes gas injection device and air bag and observes bag.The discharging tube gas injection system comprises cavity door gas gasbag, cavity door gas injecting pipe, gas injection device and the air bag observation bag that places the waste liquid precipitation tube tube wall outside, and wherein cavity door gas injecting pipe is imbedded in the tube wall of waste liquid precipitation tube.Above-mentioned two inventions are owing to be provided with air bag at the different parts of filling-discharging duct, can both control the conduit fluid flow and alleviate malaise symptoms when the row of filling that inserts intracavity preferably, the seepage phenomenon in the time of can also preventing waste liquid discharge in the human body simultaneously.But the filling-discharging duct of above-mentioned two kinds of structures all is not described in the slidably property of inserting liquid injection pipe in the body cavity internal procedure and may be to wound or the scuffing that causes in the human body lumen pore, does not consider that waste liquid precipitation tube inserts on the tube wall of the intravital part of people waste liquid and separate out the shape in hole yet.
Summary of the invention:
The present invention solves in the prior art filling-discharging duct during insertion to the technological deficiency of the easy wound of body cavity hole wall, designs a kind of simple in structurely, avoids the filling-discharging duct to lumen pore wall wound.
The present invention is achieved in that a kind of medical catheter for perfusion or discharge, comprise liquid injection pipe and waste liquid precipitation tube, the external diameter of described liquid injection pipe is less than the internal diameter of described waste liquid precipitation tube, it is characterized in that described waste liquid precipitation tube tube wall is provided with the liquid injection pipe jack suitable with the liquid injection pipe external diameter, described liquid injection pipe one end inserts by this jack also can be by being free to slide the outer intracavity that gos deep into human body of the port that extends to the waste liquid precipitation tube front end in the waste liquid precipitation tube tube chamber, above-mentioned liquid injection pipe head closely is with an outer medicated cap of being made by flexible material, outer medicated cap can be hemispherical, other shapes that semielliptical shape or outer medicated cap head are smooth cambered surface, and the top of medicated cap is provided with liquid outlet outside, can be one or more.The liquid injection pipe head of this end of main hydraulic pipe is hemispherical or is the cambered surface of smooth transition.The tube wall of the 10-20CM of the liquid injection pipe head of this end part is provided with the evenly distributed aperture of perfusion fluid in body cavity of many rows.The liquid injection pipe other end outside the tube wall of waste liquid precipitation tube and as body cavity external in cavity the port of perfusion fluid, closely linked with relevant therapy apparatus or filling apparatus or liquid storage container.Head one end of waste liquid precipitation tube is inserted the about 10-20CM of human body, and the other end is connected with the prolongation pipe of getting rid of waste liquid.The opening of waste liquid precipitation tube head can be a tack, also can be plagiocephaly.
Above-mentioned waste liquid precipitation tube probes into that the neighboring, termination of an end is the arc of smooth transition in the human body lumen pore, and the tube wall that the head of waste liquid precipitation tube is inserted the part of human body is provided with waste liquid and oozes out the hole, and waste liquid oozes out the hole and can be one or more slotted eyes.Waste liquid oozes out Kongzui and is arranged on waste liquid precipitation tube well and inserts on the tube wall of human body parts.Above-mentioned waste liquid precipitation tube adopts rubber-like medical high polymer or materials such as silica gel or latex.
Above-mentioned liquid injection pipe is provided with scale.
The present invention is provided with and the suitable jack of liquid injection pipe external diameter owing to the waste liquid precipitation tube tube wall, liquid injection pipe one end can insert in the waste liquid precipitation tube tube chamber by this jack and can extend to the outer intracavity that gos deep into human body of port of waste liquid precipitation tube front end by slip, so the simple structure of the present invention can conveniently probe in the body cavity liquid injection pipe; Liquid injection pipe probes into that the head of an end is hemispherical or be the cambered surface of smooth transition in the body cavity, can avoid liquid injection pipe to insert body cavity wound or scuffing to lumen pore wall when interior.
The liquid injection pipe head closely is with or in conjunction with an outer medicated cap of being made by flexible material, not only can effectively prevent when the liquid injection pipe head from inserting in the body cavity wound or scuffing to the lumen pore wall, can also significantly reduce the sense of discomfort of human body, flexible material can be latex, rubber, silica gel or soft resilient medical macromolecular materials.
The neighboring, termination that waste liquid precipitation tube probes into an end in the human body lumen pore is the arc of smooth transition, in the time of like this in waste liquid precipitation tube inserts human body, can not scratch the body cavity hole wall.
Waste liquid precipitation tube is provided with one or more waste liquids and oozes out the passage that oozes out that the hole has increased waste liquid, is convenient to oozing out of waste liquid.
Waste liquid precipitation tube is provided with slotted eye can prevent also that it from inserting in body cavity time the wound or scuffing can increase the seepage discharge of waste liquid simultaneously.
