Abstract
This utility model belongs to technical field of medical instruments.For solving the technical problem of the nasal feeding tube generation reflux used at present, this utility model provides a kind of counnter attack flow pattern nasal feeding tube, comprise a body, one end of body is provided with injection interface, tube wall near body other end end is provided with provisions hole, it is characterized in that: be provided with an elastic film at the tubular body of lower end, described provisions hole, elastic film and inboard wall of tube body seal fixing, elastic film is fixed a shutoff plug, shutoff plug can move up and down with the change of overpressure, under normal condition, provisions hole is closed by shutoff plug.This counnter attack flow pattern nasal feeding tube effectively can prevent gastric content generation reflux after adopting said structure, ensures that nasal feeding terminates the clean of rear tubular body, prevents body from blocking.This nasal feeding tube is rational in infrastructure, easy to operate, can be widely used in the nasal feeding operation of hospital.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically refers to a kind of counnter attack flow pattern nasal feeding tube.
Background technology
Nasal feeding tube is inserted and carried out nasal feeding art is clinical conventional a kind of basic skill operation, and the patient for patient with severe symptoms or upper digestive tract malignancy dysphagia gives nutrition.In clinical practice work, often there is reflux due to stomach voltage rise high nasal feeding tube in patient, gastric content is caused to be flowed out by nasal feeding tube, although the dispensing end of nasal feeding tube can adopt measure such as closed grade to prevent gastric content from being flowed out by nasal feeding tube end, but content attaches and easily causes nasal feeding tube to be blocked on nasal feeding tube inner chamber wall, have impact on provisions operation.
Summary of the invention
For solving the technical problem of the nasal feeding tube generation reflux used at present, this utility model provides a kind of counnter attack flow pattern nasal feeding tube.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: counnter attack flow pattern nasal feeding tube, comprise a body, one end of body is provided with injection interface, tube wall near body other end end is provided with provisions hole, it is characterized in that: be provided with an elastic film at the tubular body of lower end, described provisions hole, elastic film and inboard wall of tube body seal fixing, elastic film is fixed a shutoff plug, shutoff plug can move up and down with the change of overpressure, under normal condition, provisions hole is closed by shutoff plug.
Described provisions hole is in upper and lower two-layer setting on tube wall, and every layer is provided with two provisions holes.
When described shutoff plug is moved upward to limit, provisions hole still can be closed by shutoff plug.
Described body is provided with the opening-like state in end of shutoff plug one end.
The end that described body is provided with shutoff plug one end is cecum, and cecum has air-vent.
Described body cecum is semi-circular.
Described body tube wall is provided with length scale line.
This counnter attack flow pattern nasal feeding tube effectively can prevent gastric content generation reflux after adopting said structure, ensures that nasal feeding terminates the clean of rear tubular body, prevents body from blocking.This nasal feeding tube is rational in infrastructure, easy to operate, can be widely used in the nasal feeding operation of hospital.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is for carrying out the view of this nasal feeding tube when nasal feeding is injected.
Accompanying drawing 3 is the view of this nasal feeding tube when intragastric pressure increases.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, counnter attack flow pattern nasal feeding tube, comprise a body 1, one end of body is provided with injection interface 2, tube wall near body other end end is provided with provisions hole 3, be provided with an elastic film 4 at the tubular body of lower end, described provisions hole 3, elastic film 4 and inboard wall of tube body seal fixing, and elastic film is fixed a shutoff plug 5.
As shown in Figure 1, under normal condition, provisions hole 3 is closed by shutoff plug 5, is in isolation between body 1 internal cavity and outside.
As shown in Figure 2, when carrying out nasal feeding operation, liquid food is injected into tubular body by injecting interface 2, tubular body pressure increases, now elastic film 4 is out of shape downwards, and shutoff plug 5 is thereupon descending, in the descending process of shutoff plug 5, provisions hole 3 is progressively opened, and liquid food enters into patient's gastric by provisions hole.
As shown in Figure 3, when not carrying out nasal feeding operation, provisions hole 3 is closed, if now intragastric pressure increases, promotion elastic film 4 is upwards out of shape by this pressure, and shutoff plug 5 is up, and now provisions hole 3 is still closed, and gastric content cannot enter tube chamber inside.
Known by foregoing description, the length tackling provisions hole 3 height setting up and down and shutoff plug 5 during making makes Proper Match, in the present embodiment, provisions hole 3 is upper and lower two-layer setting on tube wall, every layer is provided with two provisions holes, the total height in two-layer provisions hole is 0.5cm, and the height of shutoff plug 5 is 1cm.When arranging, with under normal condition, the end face of shutoff plug 5 and the hole in top layer provisions hole 3 are pushed up generally within sustained height, make shutoff plug just can block provisions hole, upper strata.Adopt this setting, when carrying out provisions operation, the descending 0.5cm of shutoff plug 5 can open whole provisions hole, and when intragastric pressure increases, even if the up 0.5cm of shutoff plug also can continue to carry out shutoff to provisions hole.
For enabling intragastric pressure pass to elastic film, one end that this body is provided with shutoff plug directly can adopt open state.But for preventing body from damaging body cavity wall in plug-in type, as shown in Figure 1, in the present embodiment, semicircular cecum is arranged in this end, and cecum has air-vent 6, utilizes air-vent 6 that pressure is passed to elastic film.
The same with conventional nasal feeding tube, for controlling the insertion depth of nasal feeding tube, as shown in Figure 1, body tube wall is provided with length scale line 7.
