Abstract
A kind of indwelling gastric tube, it comprises tube body, inside described tube body, be provided with hydrophilic layer.Because the inwall at indwelling gastric tube is provided with hydrophilic layer, make liquid food not easily be attached to the surface of inwall, effectively prevent liquid food from blocking, greatly reduce the number of times of indwelling gastric tube cleaning.
Description
Technical field
This utility model relates to a kind of indwelling gastric tube, and particularly relating to that a kind of liquid food wherein not easily blocks is indwelling gastric tube.
Background technology
Indwelling gastric tube is usually used in gastrointestinal nutrition support and gastrointestinal decompression.Through stomach tube nasal feeding for going into a coma or oral feeding patient can not providing nutrition, heat and intragastric administration, it is one of main method promoting that patient recovers.
When supporting to patient, nasal feeding liquid (such as paste-forming diet, liquid food) syringe is injected via being exposed to external stomach tube one end.Because indwelling gastric tube is generally be inserted in stomach via nose, so, the diameter of indwelling gastric tube due to the restriction in nostril can not be too large.Therefore, the stomach tube just easily blocking stayed is put for a long time.Need intensified pressure to rinse after stomach tube blocking, rinse after unsuccessful needs are pulled out and again put pipe.Even at ordinary times after injecting food for patient's nasal feeding, also need to rinse stomach tube by warm water, prevent blocking.
Utility model content
Often block to solve indwelling gastric tube the problem needing cleaning, this utility model is intended to propose a kind of indwelling gastric tube that effectively can prevent blocking.
The indwelling gastric tube preventing nasal feeding liquid from blocking of the present utility model, it comprises tube body, and one end of tube body is formed with the liquid food injection port for being connected with syringe, inside described tube body, be provided with hydrophilic layer.
Preferably, described hydrophilic layer covers the inwall of whole tube body.
Because the inwall at indwelling gastric tube is provided with hydrophilic layer, make liquid food not easily be attached to the surface of inwall, effectively prevent liquid food from blocking, greatly reduce the number of times of indwelling gastric tube cleaning.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of indwelling gastric tube of the present utility model;
Fig. 2 is that the indwelling gastric tube of Fig. 1 B at A-A' place is to generalized section.
Detailed description of the invention
Below, by reference to the accompanying drawings indwelling gastric tube of the present utility model is described in detail.
As shown in Figure 1, indwelling gastric tube of the present utility model mainly comprises tube body 1, and one end of tube body 1 is the liquid food injection port 2 for being connected with syringe being exposed to patient's replacement.Here, liquid food injection port is not limited to the shape in accompanying drawing.
At the inwall of tube body 1, be provided with one deck hydrophilic layer 3, as in Fig. 2 at A-A' place B to shown generalized section.Hydrophilic layer 3 is arranged along the inwall of whole tube body 1.
Hydrophilic layer 3 can be hydrophilic silica gels material, also can be other hydrophilic materials, as utilized the polytetrafluoroethylene film of vapour deposition or the polymeric hydrophilising monomer by ultraviolet grafting---vinyl pyrrolidone (NVP), Hdyrophilic polyurethane, these are all the technology used in central venous catheter, grafting, in indwelling gastric tube of the present utility model, can obtain anticlogging indwelling gastric tube.
Hydrophilic layer of the present utility model is not limited to above-mentioned material, the water wetted material that CVP manages and uses in PICC pipe, all can use in indwelling gastric tube of the present utility model.
Due to indwelling gastric tube of the present utility model within it wall being provided with hydrophilic layer, liquid food is extremely difficult to adhere, thus effectively prevent the generation of clogging.
