Description
Technical field
The present invention relates to the technical fields of intestinal nutrient solution temperature control, more specifically, it relates to which a kind of clinic is sought with enteral
Support temperature control device and its method.
Background technique
Enteral nutrition (enteral nutrition, EN) is by nasogastric tube through side nasal cavity, oral cavity or Gastroenteritic mouth etc.
It is inserted into stomach or enteral, essential food or liquid diet are instilled out of pipe, to guarantee that patient can take in enough protein and heat
Clinical treatment.Since the elderly tissue repairing ability reduces, gastrointestinal peristalsis recovery time accordingly extends after postoperative or damage,
Therefore, the gerontal patient of acute stage progress EN support is more and more in hospital.Studies have reported that enteral nutrition gastrointestinal tract is anti-
Should be related with the temperature of nutrient solution, for domestic people constitution, in the feelings that nutrient solution does not heat or temperature is too low
Under condition, if direct infusion, the complication such as patient's abdominal distension, abdominal pain, nausea and vomiting and diarrhea are be easy to cause, if temperature is excessively high,
Not only can
Nutrient solution is caused to fail, enzymatic activitys various in enteron aisle can also be impacted.Therefore, it is necessary to nutrition before being transfused
The temperature of liquid rationally, effectively control, to reach best infusion temperature.
Currently, clinically a kind of existing enteral nutrition heating method its be by heat pipe clamp clamp intestinal nutrient solution bag
Perfusion tube and the nutrient solution in pipe is heated, and can automatic temp limit, it is excessively high to be unlikely to heating temperature.But due to this
Heat booster can only be folded in perfusion tube certain it is a bit of on, which can only be heated, and the length of perfusion tube is longer,
Therefore, the heating only in certain a bit of position can have following defect:
1, in order to effectively control the suitable temperature into intranasal nutrient solution, so the heating pipe clamp heats position and must lean on
At nearly nostril, but in this way due to being too near to nostril, and if temperature control is bad when heating, be easy to cause into intranarial
Solution temperature is excessively high and scalds patient；According to directly being heated to all liq in nutrient solution bag, add repeatedly in this way
Heat causes nutritive validity bad so that the business of nutrient solution can be lost；
2, nutrient solution is flow regime in managing, and the only heating a bit of to perfusion tube, heating effect is bad, can not arrive
Up to required temperature；Cause heating effect it is bad, heating it is unreasonable, there are problems that security risk；
3 and the only once product of product, it can not replace, cause waste serious.
In conclusion needing to improve, a heating of design is reasonable, heating effect is good, improves the product of security performance.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of clinical enteral nutrition temperature control device
And its method, heating good with heating effect rationally, improve safety, realize heated in real-time, the advantages of can recycling.
To achieve the above object, the present invention provides the following technical scheme that
A kind of clinical enteral nutrition temperature control device and its method, including the bag container for accommodating intestinal nutrient solution, institute
The output for stating bag container is connected with perfusion tube, and another end head of the perfusion tube is connected with the plug for being inserted into nostril,
Be connected with the bumping bag of double layer design between the output and the perfusion tube of the bag container, the internal layer of the bumping bag be used for
The internal layer outside of the bag container and perfusion tube connection, the bumping bag is socketed with electromagnetic heating coil, described slow
