(seven)
The peristaltic assembly comprises a universal shaped hose 25 coaxially fixed in the catheter 5, a plurality of elastic sleeves 26 sequentially connected in series on the inner wall of the universal shaped hose 25, and an energizing spring 24 penetrating inside the elastic sleeves 26, wherein when the energizing spring 24 is energized and contracted, the elastic sleeves 26 are compressed along the axial direction and generate volume expansion along the radial direction (namely, the channels of the elastic sleeves 26 are contracted or even closed).
Wherein, the universal shaping hose 25 has the following functions: when the elastic sleeve 26 is contracted, the shape of the restraining catheter 5 does not change significantly.
The inner annular sides of the elastic sleeve 26 are each helical to resemble a helical intestinal structure.
The stiffness coefficient of each energizing spring 24 itself in the conveying direction along the guide tube 5 is gradually increased, so that each contraction of the energizing spring 24 is toward the output end side of the guide tube 5 as a whole under the effect of inertia.
The peristaltic component is additionally arranged at the other improvement point of the device; the existing liquid food supply device also has the problem of overlarge irritation, which can cause more air to enter the esophagus or stomach of a patient together in the process of injecting liquid food into the digestive tract of the patient. Specifically, in the conventional liquid food supply device, a part of liquid food remains in the outflow pipe in the late feeding stage, when the residual liquid food is fed into the esophagus of the patient, it is necessary to push the food in the pipe forward by using air, water or other substances as a medium, and in this process, there is a possibility that the residual liquid food remains in the pipe in the late feeding stage when the residual liquid food is pushed into the esophagus together, and when the residual liquid food is fed into the esophagus, it is necessary to push the food in the pipe forward by using air, water or other substances as a medium, and in this process, there is a possibility that the residual liquid food such as air is pushed into the esophagus together; in addition, the conventional outflow tube itself is not inherently powered to drive the feeding of the fluid, and must rely on the pressure provided by the feeding port of the gastric tube, and since the conventional outflow tube is generally assisted by a syringe (the syringe has a limited single volume), the medical staff needs to reuse the syringe to suck the fluid, there is a short separation between the syringe and the catheter, the orifice of the feeding port of the outflow tube must be exposed to the outside during the process, so that the outside air enters the gastric tube (because the esophagus of the patient has peristaltic feeding capability, the fluid in the gastric tube continues to flow downwards during the process, and the air at the upper end of the gastric tube cannot be pumped out by the medical staff during the next feeding), thereby causing the phenomena of flatulence and food reflux in the patient.
By adopting the structure of the device in this embodiment, the liquid food in the catheter 5 can be continuously extruded by the elastic sleeve 26 to flow towards the esophagus, so that the technical problems are avoided to the greatest extent, and the irritation in use is effectively reduced.
The present invention is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present invention without departing from the technical content of the present invention still belong to the protection scope of the technical solution of the present invention.
