Be provided with from expanding a liquid section on the nose intestines hose body, can automatic expand out in the enteric cavity, not only enlarged the liquid outlet area, effectively avoided the liquid outlet to hug closely the jam that intestinal wall led to the fact simultaneously, metal seal wire one end has the crotch, and the other end has the steel wire ball, prevents metal seal wire roll -off lumen among the operation process, the damage intestines tube.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically refers to a kind of nasointestinal tube, particularly relates to a kind of Novel anti-blockage nasointestinal tube.
Background technology
Nasointestinal tube widely uses in clinical position, and at present commercial or general nasointestinal tube is made up of the medical grade polyurethane material of X-ray opaque ray, is generally divided into the nasointestinal tube of two kinds of structures.
Wherein a kind of head end of nasointestinal tube is that round blunt shape is closed, and have one or more sides to cut liquid outlet, area is less, and head end is that alloy imports port (counterweight tube), and port and inner cavity of pipe are all covered with water active lubricant.In general, in clinical position, when medical worker puts pipe to patient, can only put pipe to gastric, nasointestinal tube passes through pylorus voluntarily by gastric motility.Because liquid outlet is side otch, when intestinal wall pressed close to by conduit, liquid outlet is caused relatively to block.
Another kind of nasointestinal tube adopts spiral helicine head end, and spiral helicine nasointestinal tube is made up of nose intestinal hose body and the guide wire inserted in described nose intestinal hose body.In use, need described nose intestinal hose body to be inserted in 12 rectum of human body or jejunum and carry out nutrition nursing, when hospital operation personnel put pipe to patient, pipe can only be put to gastric, Novel nose intestinal tube is allowed to pass through pylorus voluntarily by gastric motility, but critical patient is because the strike of disease, often there is gastric hypokinesia or disappearance, pylorus can only be passed through by operation under x-ray or gastroscope, length consuming time, and misery and the medical expense of patient can be increased, bring unnecessary trouble and workload to medical personnel simultaneously.
At work, we find, especially the patient that reduces of gastrointestinal function, and nasointestinal tube is easy to block, and is multiplely born in conductor housing end.The nasointestinal tube of some patients is still obstructed after rinsing, can only pull out the nasointestinal tube more renewed.
Utility model content
This utility model, in order to overcome deficiency of the prior art, provides a kind of Novel anti-blockage nasointestinal tube, is convenient to hand-held on the one hand, prevents damage tube chamber and intestinal tube, can expand the area of liquid outlet on the other hand, prevent blocking.
This utility model is achieved through the following technical solutions:
A kind of Novel anti-blockage nasointestinal tube, comprise the nose intestinal hose body stretched in human body the intestines and stomach and the wire guide inserted in described nose intestinal hose body, the front end of described nose intestinal hose body is cecum, and it is similar to arc-shaped sub warhead, the end of described nose intestinal hose body is Y type port, one of them interface is the steel wire inlet end for wire guide turnover, another interface is the liquid feeding end entered for medicine or nutritional solution, and steel wire inlet end, liquid feeding end all communicates with nose intestinal hose body inside, described nose intestinal hose body end certain position place is being provided with the self-expanding fluid section be made up of shape memory alloy material, one end of described wire guide is with crotch, the other end is provided with steel wire lump.
As optimal technical scheme of the present utility model, described steel wire inlet end and liquid feeding end are provided with sealing cap.
As optimal technical scheme of the present utility model, described nose intestinal hose body is made up of polyurethane material, and its external diameter is 3.5mm-4mm, and internal diameter is 2.5mm-3mm, and length is 110cm-140cm.
Compared with prior art, the beneficial effects of the utility model are:
1, the nose intestinal hose body in this utility model is provided with the self-expanding fluid section be made up of shape memory alloy material, can be automatically swelling in enteric cavity, general in lantern, not only expand liquid outlet area, effectively prevent liquid outlet simultaneously and be close to the blocking that intestinal wall causes;
2, the wire guide one end in this utility model, with crotch, is convenient to hand-held, is used for regulating conduit direction of travel, and the other end, with steel wire lump, prevents wire guide in operating process from skidding off tube chamber, damage intestinal tube.
Accompanying drawing explanation
Fig. 1 is the state diagram that this utility model wire guide inserts in nose intestinal hose body process;
Fig. 2 is the state diagram after this utility model wire guide inserts nose intestinal hose body;
Fig. 3 is the state diagram after this utility model wire guide extracts nose intestinal hose body out.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Novel anti-blockage nasointestinal tube that the present embodiment provides, comprise the nose intestinal hose body 1 stretched in human body the intestines and stomach and the wire guide 2 inserted in described nose intestinal hose body 1, described nose intestinal hose body 1 is made up of polyurethane material, its external diameter is 3.5mm-4mm, internal diameter is 2.5mm-3mm, and length is 110cm-140cm.
The front end of described nose intestinal hose body 1 is cecum, and it is similar to arc-shaped sub warhead, the end of described nose intestinal hose body 1 is Y type port, one of them interface is the steel wire inlet end 30 passed in and out for wire guide 2, another interface is the liquid feeding end 31 entered for medicine or nutritional solution, and steel wire inlet end 30, liquid feeding end 31 all communicate with nose intestinal hose body 1 inside, described steel wire inlet end 30 and liquid feeding end 31 are provided with sealing cap 3.
Described nose intestinal hose body 1 end certain position place is being provided with the self-expanding fluid section 10 be made up of shape memory alloy material, and one end of described wire guide 2 is with crotch 20, and the other end is provided with steel wire lump 21.
As shown in Figure 1, when wire guide 2 inserts the inside of nose intestinal hose body 1, the sealing cap 3 at steel wire inlet end 30 place opens, hand-held crotch 20, the steel wire lump 21 of wire guide 2 is stretched in nose intestinal hose body 1, by the trend of direction controlling nose intestinal hose body 1 in human body alimentary canal of wire guide 2, accurately to arrive object position.As shown in Figure 2 and Figure 3, when steel wire lump 21 arrives the cecum of nose intestinal hose body 1, steel wire lump 21 tightly can be wrapped by the cecum of nose intestinal hose body 1, prevent wire guide 2 in operating process from skidding off tube chamber thus damage intestinal tube, now, the self-expanding fluid section 10 be made up of shape memory alloy material expand into ellipse from strip, can be automatically swelling in enteric cavity, general in lantern, increase liquid discrepancy area, not easily block, and the self-expanding fluid section of ellipse, form is comparatively fixing, not easily adsorbs coat of the stomach, does not affect liquid and comes in and goes out.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
