Abstract
The invention belongs to the field of medical instruments and provides a nasal feeding tube with an elastic conical sealing opening in the gastric end. The nasal feeding tube comprises a nasal feeding tube body 1, and the nasal feeding tube body 1 comprises an external injection section 2, a extranasal section 3 and an intranasal section 4 which are sequentially connected; the external injection section 2 comprises a fluid inflow port 5, and the intranasal section 4 comprises a nasal cavity section 6, a throat section 7, a esophagus section 8 and an intragastric section 9 which are sequentially connected; the intragastric section 9 comprises a fluid outflow port 10; an elastic anti-reflux device 11 is installed at the fluid outflow port 10, is in a sealing opening tube shape and comprises a connection edge 12, an outlet edge 13 and a connection tube 14 for making the connection edge 12 and the outlet edge 13 connected; the connection edge 12 is connected with the fluid outflow port 10, and the diameter of the connection edge 12 is larger than that of the outlet edge 13. Compared with the prior art, the nasal feeding tube has the advantages that the situation that gastric juice or food enters the nasal feeding tube when a patient vomits due to reflux can be effectively prevented, and accordingly gastropulmonary infection caused by reflux aspiration is effectively prevented.
Description
Technical field
The invention belongs to medical instruments field, it is related to a kind of nasogastric tube, is related specifically to a kind of stomach end and sets flexible
The nasogastric tube that taper is closed up.
Background technology
Nasogastric tube is used in the middle of nasal feeding.Nasal feeding be exactly nasogastric tube by nasal cavity send into patient's stomach in, from nasogastric tube
Interior infusion food, moisture and medicine.Typically be useful in and trencherman can not be entered by mouth, such as after oral disease, operation on oral cavity, oesophagus it is narrow
Narrow, esophago-tracheal fistula, some Post operations or tumour patient, it is impossible to the patient for dehiscing, such as stupor, lockjaw, premature and the state of an illness
Critical patient, and the patient that refusal is taken food.
Foreign countries have scholar to report, inhaling incidence due to the mistake that gastric content reflux causes has risen to 30.5% ~ 40.8%.
Reflux inhales caused Gastropulmonary infection approach by mistake has turned into the Etiological of pneumonia, often jeopardizes patient vitals.Its is main
Mechanism is：1st, the gastric juice of reflux can directly etching air flue respiratory tract and alveolar epithelial cells and cause chemical inflammatory, in body
During immunity degradation, easily cause infective airway inflammation and severe pneumonia.2nd, the mistake that larger amount of gastric content causes is inhaled can
Through stomach, esophagus, air flue, lung approach, the bronchial obstruction of many lobes of the lung is caused, and cause pulmonary abscess, respiratory failure, or even asphyxia.
Therefore, it is necessary to improved technical scheme is provided, to overcome prior art technical problem present in.
The content of the invention
It is an object of the present invention to provide a kind of stomach end is provided with the nasogastric tube of elastic cone closing in, can effectively prevent
Only when reflux occurs in patient to vomit, gastric juice or food enter in nasogastric tube, so that effectively prevent from being inhaled because of reflux by mistake caused by
Gastropulmonary infection.
In order to achieve the above object, the invention provides the nasogastric tube that a kind of stomach end is provided with elastic cone closing in, bag
Nasogastric tube body is included, the nasogastric tube body includes the external injection portion, the outer section of nose and the intranasal section that are sequentially connected, described external
Injection portion includes fluid inbound port, and the fluid inbound port is located remotely from the outer section side of the nose；Intranasal section include according to
The nasal cavity section of secondary connection, throat section, oesophagus section and stomach inner segment, nasal cavity section are connected with the outer section of the nose；In the stomach
Section includes fluid exit port, and the fluid exit port is located remotely from the oesophagus section side；At the fluid exit port
Flexible antireflux device is installed, the elastic antireflux device is in closing in tubulose, including connect edge, go out edge and connection it is described connect edge and
It is described go out edge connecting tube, the edge that connects is connected with the fluid exit port, it is described connect edge with diameter greater than it is described go out edge
Diameter.
When injecting fluid shape food or medicine thing is needed, syringe nozzle is inserted the fluid inbound port of external injection portion first
Place, force squeezes into fluid, fluid from external injection portion, the outer section of nose, nasal cavity section, throat section, oesophagus section, into stomach inner segment, and
The final fluid exit port from stomach inner segment is flowed into stomach.In fluid flows into the elastic antireflux device gone out installed in fluid exit port
When, due to pressure so that the connecting tube of elastic antireflux device opens expansion, go out edge diameter and become big, connect edge certainly so as to reach fluid
To connecting tube, finally from the purpose for going out edge inflow.And when special circumstances occur and cause patient's reflux to vomit, due to liquid pressure
Power is located at outside connecting tube, therefore is gone out the diameter of edge and will not be become big, and connecting tube will not be expanded, therefore in the food in stomach, medicine
Thing or gastric juice cannot be introduced into nasogastric tube, prevent from inhaling caused Gastropulmonary infection by mistake because of reflux so as to reach.
Preferably, the making material of the elastic antireflux device is elastic caoutchouc.
Preferably, it is described connect edge it is a diameter of described go out 2 ~ 4 times of edge diameter.It is further preferable that the diameter for connecing edge
For it is described go out 3 times of edge diameter.Connect edge and be difficult to differ excessive or very few with the diameter for going out edge, difference excessively easily causes to go out every time
Edge diameter change amplitude is excessive, causes out port at edge to rupture, so as to reduce the life-span of elastic antireflux device；And it is too small can not be very
The good reflux liquid that prevents invades nasogastric tube.
The fluid inbound port for being preferably located at the external injection portion goes out to be provided with block.It is further preferable that described
Block is fixed in the external injection portion by a connecting rope.Setting block can effectively prevent nasogastric tube in off working state
Lower entrance foreign matter.
Preferably, the connecting tube connects edge Zi described in and goes out edge described in, in from urgency to slow closing-in structure.It is so designed that,
When there is reflux situation, the hydraulic pressure outside connecting tube can force connection caliber it is compressed small, that is, go out at edge occur it is totally-enclosed or
Semi-closed state, greatly prevent because of reflux and caused by liquid enter nasogastric tube.
It is preferably located in the outer section of the nose and is provided with anti-skidding fixture.Nasogastric tube can for a long time put within a period of time
Enter in patient's body, setting anti-skidding fixture can effectively prevent nasogastric tube from being skidded off from nasal cavity in the case of inessential and cause to need
Situation about inserting again occurs.
Compared with prior art, the beneficial effects of the present invention are：Can effectively prevent when reflux vomiting occurs in patient,
Gastric juice or food enter in nasogastric tube, so that Gastropulmonary infection effectively prevent from being inhaled because of reflux by mistake caused by.
