Description
Technical Field
The utility model relates to the technical field of auxiliary medical equipment, in particular to nutrient solution input speed adjusting device in simple and easy intestines.
Background
In clinic, a plurality of patients need enteral nutrition, and the current enteral nutrient solution adopts a hollow skin strip similar to a stomach tube to directly deliver the nutrient solution into the stomach. But the rate of nutrient infusion needs to be adjusted according to the response of the patient. If a special nutrition pump is adopted, the cost of the nutrition pump is too high, and the ordinary grade hospitals cannot purchase a large amount of nutrition. And the nutrition pump occupies a small area, and the bedside of a severe patient is an instrument, so that the work and the basic care are influenced.
If the speed regulator on the infusion leather strip is adopted, the stomach tube has larger hardness relative to the infusion leather strip, and although the stomach tube has certain elasticity, the tube diameter can be changed through the extrusion of external force. However, the pressure generated by the speed regulator on the infusion leather strip during speed adjustment is very small, and compared with the hardness of the gastric tube, the pressure which can change the tube diameter of the gastric tube cannot be generated at all.
Therefore, how to design an adjusting device which has low cost and can generate enough pressure on the gastric tube to change the tube diameter of the gastric tube so as to change the speed of nutrient solution infusion into the stomach becomes a technical problem to be solved in the prior art.
SUMMERY OF THE UTILITY MODEL
The applicant has studied and developed the above-mentioned drawbacks of the prior art to provide a simple enteral feeding rate adjustment device.
In order to solve the above problem, the utility model adopts the following scheme:
the simple enteral nutrient solution infusion speed adjusting device comprises a cylindrical main body, an adjusting knob, a pressurizing block and a bottom plate;
the upper end of the cylindrical main body is closed, the lower end of the cylindrical main body is open, the cylindrical main body is hollow, a through hole is formed in the closed position of the upper end of the cylindrical main body, and internal threads are formed in the inner wall of the through hole;
the upper end of the adjusting knob is provided with an adjusting turntable, the lower end of the adjusting knob is cylindrical, the outer surface of the lower end of the adjusting knob is provided with an external thread matched with the internal thread of the through hole of the cylindrical main body, and the lower end of the adjusting knob is assembled on the inner wall of the through hole of the cylindrical main body;
the bottom of the lower end of the adjusting knob is connected with a pressurizing block;
the bottom of the cylindrical main body is connected with a bottom plate.
As a further improvement of the above technical solution: the bottom of the lower end of the adjusting knob is provided with a blind hole, the inner wall of the blind hole is provided with internal threads, a counter bore is arranged in the middle of the pressurizing block, a screw is assembled in the counter bore, the screw penetrates through the counter bore and is screwed in the blind hole, and the pressurizing block and the bottom of the lower end of the adjusting knob are fixed.
As a further improvement of the above technical solution: the bottom plate is connected with the bottom of the cylindrical body through the insert blocks, and the insert blocks have different heights so as to adjust the distance between the bottom plate and the bottom of the cylindrical body.
The technical effects of the utility model reside in that:
during the use, put into between bottom plate and the pressurization piece with the one end of stomach tube, the rotation regulation carousel, the external screw thread of adjust knob lower extreme and the internal thread of cylindric main part through-hole inner wall mutually support, produce or upper or lower pressure, and when adjust knob rotated down, the pressurization piece transmitted decurrent pressure to the stomach tube. Due to the fact that the thread pressurization is adopted, the generated pressure is large enough compared with the hardness of the stomach tube, the squeezing effect can be generated on the tube wall of the stomach tube, the tube diameter of the stomach tube is changed, and therefore the speed of nutrient solution infusion into the stomach is changed.
The regulator can replace a nutrition pump, control the speed of enteral nutrition patients, reduce the consumption of consumables and reduce the use area.

Detailed Description
The following describes the present invention with reference to the accompanying drawings.
As shown in FIGS. 1 to 5, the simple enteral nutrient solution feeding rate adjusting device comprises a cylindrical body 2, an adjusting knob 1, a pressurizing block 5, and a bottom plate 7; the upper end of the cylindrical main body 1 is closed, the lower end of the cylindrical main body is open, the cylindrical main body is hollow, a through hole is formed in the closed position of the upper end of the cylindrical main body, and internal threads are formed in the inner wall of the through hole; the upper end of the adjusting knob 1 is provided with an adjusting turntable, the lower end of the adjusting knob is cylindrical, the outer surface of the lower end of the adjusting knob is provided with an external thread matched with the internal thread of the through hole of the cylindrical main body 2, and the lower end of the adjusting knob 1 is assembled on the through hole of the cylindrical main body 2; the bottom of the lower end of the adjusting knob 1 is connected with a pressurizing block 5; the bottom of the lower end of the adjusting knob 1 is provided with a blind hole, the inner wall of the blind hole is provided with an internal thread, a counter bore is arranged in the middle of the pressurizing block 5, a screw 4 is assembled in the counter bore, the screw 4 penetrates through the counter bore and is screwed in the blind hole, and the pressurizing block 5 and the bottom of the lower end of the adjusting knob 1 are fixed. The bottom of the cylindrical body 2 is connected with a bottom plate 7. The bottom plate 7 and the bottom of the cylindrical body 2 are connected by inserts 6, the inserts 6 having different heights to adjust the distance between the bottom plate 7 and the bottom of the cylindrical body 2.
During the use, put into between bottom plate 7 and the pressurization piece 5 with the one end of stomach tube 3, the rotation regulation carousel, the external screw thread of adjust knob 1 lower extreme and the internal thread of cylindric main part 2 through-hole inner wall mutually support, produce or upper or lower pressure, when adjust knob 1 down rotated, pressurization piece 5 transmitted stomach tube 3 with decurrent pressure. Due to the adoption of the thread pressurization, the generated pressure is sufficiently larger than the hardness of the gastric tube, and the tube wall of the gastric tube 3 can be squeezed to change the tube diameter of the gastric tube, so that the speed of nutrient solution infusion into the stomach is changed. Specifically, the feeding speed of the nutrient solution can be slowed down by increasing the pressure, and the feeding speed can be increased or adjusted to the maximum by reducing the pressure or not applying the pressure.
