Abstract
Description
The present invention relates to a fluid feed device, and more particularly to a screw-type fluid feed device for supplying a fluid to the intestines of patients unable to chew or swallow food by themselves using a screw feed method.
Unconscious and impaired patients who are unable to chew or swallow food themselves have been offered intestinal feeding (e.g., stomach or duodenum) using fluid in addition to calorie supplementation by injection known as intravenous injection. .
Intestinal feeding inserts a feeding tube through the nasal cavity or mouth of the patient to the intestine, connects a syringe containing water or fluid to the feeding tube, and lifts the syringe up so that the fluid is fed into the intestine by gravity. In addition, the nurse or assistant pressurizes the syringe so that the fluid or fluid in the syringe can be supplied into the intestine.
Such a conventional method requires a lot of time to inject the formula because the nurse or guardian must inject the formula directly to the patient. In addition, there is a problem in that when the pressure applied to the syringe during the injection of the fluid can damage the esophageal mucosa of the patient. In addition, the nurse or guardian has to change the syringe several times to supply the fluid, and there may be a hygiene problem due to bacterial invasion by contact during replacement.
In order to improve this problem, there is a method of supplying a liquid by putting the liquid in a container such as a ringer solution pack and then suspending the ringer solution pack high, but in this case, due to the limitation of single use, it is not torn and used. Since it is not a fixed shape to stand up, there is considerable inconvenience in moving and hanging in a fixed manner.
Republic of Korea Utility Model No. 0309884 discloses a fluid supply container for patients. The disclosed fluid supply container has a cover having at least one connector formed on a sidewall, an upper end opening and an air inlet formed at an upper end thereof and selectively communicating with the connector, coupled to the cover, and a discharge hole protruding from the lower end thereof, and having a fluid inside. It consists of a nozzle unit that is detachably sealed to the body to be filled and the discharge port of the body.
However, the fluid supply container is formed in a cylindrical shape to maintain a fixed form compared to using the existing ringer solution pack somewhat uncomfortable, but the injection or injection of the fluid by the nurse or guardian by adjusting the area of the air intake The amount of air must be adjusted manually, so care must be taken while the nurse or guardian watches. Therefore, there is a problem of lowering the efficiency of nursing work due to waste of time. In addition, it is difficult to control the supply time and the feed rate because the flow is injected by gravity by opening the air inlet, there is an inconvenience to close the air inlet again when the supply of the flow is complete.
Republic of Korea Patent No. 0929051 discloses a food injection device. The disclosed food injection device has a problem in that it is difficult to supply the fluid to the patient at a uniform pressure as a structure in which the fluid is pressurized by the weight of the pressurized liquid injected into the pressure vessel to discharge the fluid to the bottom. In addition, it is very difficult to properly adjust the pressure applied to the formula.
The present invention has been made to improve the above problems, it is not a way to flow the formula down by gravity or pressurize the formula from the top to discharge the formula as in the prior art to rotate the screw inside the container is filled with the formula It is an object of the present invention to provide a screw-type flow feeder capable of discharging the flow at a uniform pressure and speed.
Another object of the present invention is to provide a screw-type liquid feed device that can supply the flow according to the characteristics of each patient by allowing the flow rate of the flow can be controlled differently.
Screw type fluid supply device of the present invention for achieving the above object is a container containing a receiving space that is filled with the flow formula; A feeding housing formed at a lower portion of the accommodation container and provided with an outlet through which the flow type is introduced into the inside and the flow type can be discharged to the outside; A screw member rotatably installed in the feeding housing to transfer a flow type introduced into the feeding housing to the discharge port; A cap coupled to an upper portion of the accommodation container and provided with a drive motor; And a power transmission unit connecting the drive motor and the screw member to transfer the rotational force of the drive motor to the screw member.
And an operation unit installed at the cap to control a rotational speed of the screw member to control the discharge speed of the flow type.
The power transmission unit is characterized in that it comprises a rotary shaft which is coupled to the screw member and extended upward, and installed on the rotary shaft and the drive shaft of the drive motor, respectively, to separate and couple the rotary shaft and the drive shaft. .
In order to prevent the fluid from leaking to the outside of the container is provided with a cover detachably coupled to the upper portion of the container, the cover is a circular panel in close contact with the inner peripheral surface of the container, and the panel It protrudes downward from the center of the support for the rotatable shaft to be rotatable, characterized in that it has a shaft support provided with a mounting space for receiving the coupling therein.
The accommodation container is characterized in that the receiving space is gradually narrowed toward the lower portion to guide the movement of the flow type filled therein into the feeding housing, the side surrounding the receiving space is formed as a parabolic surface.
The screw member has a boss having an insertion groove into which the rotation shaft is inserted, and a rib which is formed in a spiral twist on the outer circumferential surface of the boss and pushes the flow formula to the outlet when rotating, and the pressure of the flow formula discharged through the outlet port is Ascending, it characterized in that a plurality of conveying grooves are formed in the rib to move the flow in the opposite direction of the outlet.
As described above, according to the present invention, a separate feeding housing is provided at the lower portion of the receiving container filled with the liquid, and the screw member installed in the feeding housing is rotated to discharge the liquid, thereby injecting the liquid to the patient at a uniform pressure and speed. Can be.
In addition, by adjusting the rotational speed of the screw member it is possible to easily adjust the amount and speed of the discharged to suit the characteristics of each patient.
In addition, when the fluid moving through the feeding tube connected to the nasal cavity or mouth of the patient is stopped, the fluid flows through the receiving grooves formed in the rib to prevent the increase in the pressure applied to the fluid by damaging the patient's esophageal mucosa. The case of adding can be prevented beforehand.

Hereinafter, a screw type fluid supply apparatus according to a preferred embodiment of the present invention will be described in detail.
In the description of the present invention, the formula is supplied to the intestinal tract to supply nutrients and moisture to people who cannot chew or swallow food on their own, such as unconscious and unpowered or gastrointestinal patients, such as taste, milk, porridge, soup, etc. It means food that can be eaten without chewing. In addition, the formula is a concept containing water.

The
If the feeding is no longer injected into the patient's intestine and the feeding is stopped in the feeding tube, if the screw member continues to rotate, the pressure applied to the feeding tube is increased. At this time, forced injection of fluid by high pressure may damage the esophageal mucosa of the patient. However, in the present invention, even if the screw member continues to rotate, when the pressure applied to the fluid is increased, the fluid is pushed upward through the conveying
In the above, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary and will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.
Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
