Abstract
The utility model relates to a medical instrument, in particular to a multi-head reinforced stomach tube used for gastrointestinal decompression in a thorax and abdomen operation period, nutrient feeding for intestines of a critical patient and gastrolavage. The multi-head reinforced stomach tube comprises a stomach tube body, wherein the stomach tube body is partitioned into a working tube cavity and one or more reinforcing cavities through diaphragms, the cross section of the diaphragms is arc, the tube diameter of the working tube cavity is 80-90% that of the stomach tube body, the far end of the working tube cavity is provided with an arc incision or a flow hole, the far ends of the reinforcing cavities are blind ends, guide wires are inserted in the reinforcing cavities, and the ends, extending out of the reinforcing cavities, of the guide wires are connected with a handle. The guide wires are inserted into the reinforcing cavities to form the guide wire reinforcing cavities, so that the hardness of the whole stomach tube body is enhanced to ensure that the stomach tube smoothly passes through the nasopharynx and reach the stomach, after the stomach tube reaches the stomach, the guide wires are pulled out, so that softness of the tube body is recovered, and the stomach tube can be indwelled in the body of a patient for a long time.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of supply of enteral nutrition for the gastrointestinal decompression of corrective surgery phase of breast abdominal part, patient with severe symptoms and the reinforced stomach tube of the bull of gastric lavage.
Background technology
In the clinical application of Hospitals at Present, stomach tube is mainly used in supply and the gastric lavage of the gastrointestinal decompression of corrective surgery phase of breast abdominal part, patient with severe symptoms's enteral nutrition.But a large amount of stomach tubes that use but exist many-sided deficiency in now clinical, one is single chamber stomach tube, has following defect in clinical practice:
1, existing body material is commonly PVC material, body is very soft, when via intranasal application is inserted stomach tube, often because body hardness cannot be passed through patient's nasopharynx part not, thereby cause intubation defeat, during for patient with severe symptoms's nasal feeding, because stomach tube needs indwelling several weeks, because of the limitation of body material, most patients there will be the reactions such as nasopharynx part discomfort, mucosa injury, bring misery to patient;
2, the flow mouth of the body end of stomach tube is less, easily causes in pipe and stops up;
3, not only nonsensical when the female Luer in the stomach tube of the single chamber of bull is at clinical more medicine dressing change bag, decompression drainage bag, increase on the contrary medical personnel's workload.
, in clinical practice, there is following defect in another kind of relatively advanced person's the three chamber stomach tube that adopts:
1, body is divided into after three lacunas, three intraluminal useful spaces are diminished, because strength of fluid, the granular size of clinical gastrointestinal decompression and nasal feeding differ, and three too small can not passing through smoothly for this liquid that contains particle diameter larger particles of the intraluminal useful space, often need impressed pressure pump could allow medicine pass through, therefore the existing three chamber stomach tube demand that contains these type of class treatments such as greater particle size granule in the liquid of administration of cannot satisfying the demand;
2, three chamber stomach tube separates relief chamber and nursing chamber, but in clinical treatment, need gastrointestinal decompression in advance for this type of patient, and gastric flushing, then carry out nasal feeding nursing according to conditions of patients, therefore can there is not pollution problem, there is no need completely to be separated, that after relief chamber and nursing chamber are separated,, because diameter is all too little, decompression drainage, nasal feeding are fed and all can not be reached effect very smoothly on the contrary;
3, three lumens all have flow mouth diameter at Yu Fu chamber, main chamber end and are about 3-4mm, and work seal wire diameter is about 1mm, in the time of plugging, because stomach tube kidney basin is in gastric, when the seal wire that diameter is less inserts dredging again, seal wire front end is very easy to go out from flow mouth, injures coat of the stomach, when serious, can cause the symptoms such as hemorrhage;
4, be designed to "T"-shapedly because the inner chamber of three lumens cuts off, this insulating course can cause body hardening, the patient who needs nasal feeding at all cannot indwelling several weeks.
Summary of the invention
The purpose of this utility model is the defect in order to overcome existing single chamber, the existence of multi-cavity stomach tube, and when a kind of patient's Preserving time is provided, comfort level is good, body is soft, hardness is adjustable, be difficult for obstruction, high concentration liquid feeds the reinforced stomach tube of bull smoothly.
For achieving the above object, the reinforced stomach tube of a kind of bull of this utility model design, comprise stomach tube, described stomach tube is divided into work tube chamber and one or more reinforcements chamber by barrier film, and the cross section of described barrier film is arc, and described instrumentation tubes lumen footpath is the 80-90% of stomach tube caliber, the far-end of described work tube chamber is provided with curved incision or metering orifice, described reinforcement chamber far-end is cecum, strengthens intracavity and is inserted with seal wire, and the end that described seal wire stretches out described reinforcement chamber is connected with handle; Described work tube chamber end is connected with female Luer, and described female Luer is connected with universal adaptor, and described universal adaptor is used for connecting various syringes, nutrient bag or medical drainage bag.
In technique scheme, end, described reinforcement chamber is connected with locking type female Luer.
In technique scheme, described instrumentation tubes intracavity is inserted with seal wire.
In technique scheme, described female Luer is Y shape female Luer, Y shape female Luer has two interfaces to be positioned at outside stomach tube, seal wire gos deep into gastric tube inserting from a mouth of Y shape female Luer, in the time that needs extract gastric juice, can extract gastric juice from another mouthful of Y shape female Luer, and seal wire need not be taken out to more convenient operation.
In technique scheme, stomach tube is made up of polyurethane material, and the body that this material is made is softer, and when patient's Preserving time, comfort level is good.
This utility model adopts the larger main chamber of diameter as work tube chamber, and its diameter accounts for the 80-90% of the total caliber of whole stomach tube, can effectively guarantee high concentration, oarse-grained liquid by and do not stop up; Strengthen being inserted with seal wire in chamber and form seal wire reinforcement chamber, strengthening chamber does not communicate with working chamber, when inserting, seal wire strengthens behind chamber, can strengthen the hardness of whole stomach tube body, to guarantee that this stomach tube, smoothly by nasopharynx part, arrives stomach, arrive after gastric, seal wire is extracted, recovered the pliability of body, patient can Preserving time.
Reinforcement of the present utility model chamber completes intubate, extracts after seal wire, strengthens the termination locking type female Luer sealing in chamber.Only in the process of intubate, need to use owing to strengthening chamber, in other situation of clinical treatment and nursing, seal, locking type female Luer of the present utility model is tightened formula locking mechanism for rotating, need to use time, locking type female Luer is rotatably unscrewed, and while not needing to use, rotation is tightened, very convenient to use, after screwing, can effectively prevent that ambient atmos, liquid from entering reinforcement chamber and polluting.
This utility model has the camber otch of large flow in work lumen distal, to guarantee passing through of high concentration liquid.Work tube chamber outer end head is connected with female Luer, and the external universal adaptor of female Luer, can be connected with the syringe of various models, nutrient bag, drainage bag, reduces clinical nursing activity amount.
