Description

Technical Field

[0001] The present invention relates to the technical field of feeders, in particular to a partitioned liquid food feeding device for critically ill patients. Background Art

[0002] Severely ill patients need to lie in bed and cannot sit up or take care of themselves. However, they must have sufficient nutrition to meet their body's consumption. Therefore, they need to be fed by nurses. When feeding patients, they can only be fed liquid food, which is easier for patients to digest and absorb. Traditional patient feeding devices still have various problems and are difficult to meet actual usage needs. After searching, the Chinese invention patent publication number CN114146001B discloses a liquid food feeder for intensive care nursing in internal medicine. The patent uses a push rod piston to push the liquid food in the connecting cavity through the regulating tube and the gastric tube to deliver the liquid food to the patient's stomach. When the patient has reflux, vomiting and other phenomena during feeding, the refluxed liquid food or gastric fluid is pumped into the connecting cavity by pulling the push rod piston in the opposite direction. A reflux cavity connected by a one-way valve is provided below the connecting cavity, and the liquid food and gastric fluid drawn back from the connecting cavity are transported to the reflux cavity, thereby facilitating the removal of the liquid food or gastric fluid. The push rod drives the piston to squeeze the connecting cavity multiple times, and the connecting cavity is flushed with new liquid food to avoid liquid food contamination, thereby realizing the diversification of the device.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the use of a connecting cavity to store liquid food for feeding patients and liquid food and gastric juice refluxed and vomited by patients can easily cause contamination of the connecting cavity and new liquid food. Although the connecting cavity is flushed with new liquid food, it cannot be guaranteed that the contamination in the connecting cavity is cleaned properly, and it causes waste of liquid food. The operation method is also relatively cumbersome and has limitations. Therefore, a separated liquid food feeding device for critically ill patients is proposed to solve the above problems. Summary of the Invention

[0004] In order to solve the problems in the above background technology, the present invention provides a partitioned liquid food feeding device for critically ill patients.

[0005] The present invention adopts the following technical solution: a separated liquid food feeding device for critically ill patients, comprising a main box body, wherein a first storage chamber and a second storage chamber are respectively provided in the main box body, a push rod is respectively installed in the first storage chamber and the second storage chamber, a piston which matches the inner wall of the first storage chamber or the second storage chamber is installed at the end of the push rod, a connecting seat and a Y-shaped three-way pipe are fixedly installed on the outer end surface of the main box body, a first tube cavity and a second tube cavity are respectively provided in the connecting seat, one end of the first tube cavity and the second tube cavity are respectively connected to the two branches of the Y-shaped three-way pipe, the other end of the first tube cavity and the second tube cavity are respectively connected to the first storage chamber and the second storage chamber, the main pipe of the Y-shaped three-way pipe is connected to a gastric tube introduced into the patient's stomach, and an opening and closing component for adjusting the closure or opening of the first tube cavity and the second tube cavity respectively is movably installed in the connecting seat.

[0006] As a preferred embodiment of the present invention, the opening and closing member is a columnar adjusting block, which is movably installed in the connecting seat in the vertical direction and rotates around the center of the connecting seat in the vertical direction. A connecting groove that passes through the adjusting block is provided at a position off-center of the adjusting block, and the connecting groove corresponds to the positions of the first tubular cavity and the second tubular cavity respectively after the adjusting block rotates.

[0007] As a preferred embodiment of the present invention, the shapes of the first tubular cavity, the second tubular cavity and the connecting groove are all circular cylindrical grooves arranged in the horizontal direction, and the diameters of the inner circular grooves of the first tubular cavity and the second tubular cavity are smaller than those of the connecting groove.

[0008] As a preferred embodiment of the present invention, a semicircular limiting groove is provided in the connecting seat, and a limiting pin is fixedly provided on the side of the adjusting block that contacts the limiting groove. The limiting pin is inserted into the limiting groove and is slidably connected to the limiting groove.

[0009] As a preferred embodiment of the present invention, elastic blocks for fixing the limiting pin are provided on the inner walls at both ends of the limiting slide groove in the vertical direction, and the elastic blocks are in contact with the limiting pin.

[0010] As a preferred embodiment of the present invention, an opening for adding liquid food is provided on the outside of the main box body, a connecting cover is installed at the opening, a ring tooth for installing the connecting cover extends outward from the opening of the main box body, and the connecting cover is connected to the ring tooth by a thread.

[0011] As a preferred embodiment of the present invention, a sealing plug having a shape and size matching the shape of the main box body opening is extended from the inner wall of the connection cover toward the first storage cavity, and the outer end surface of the sealing plug is flush with the inner wall of the first storage cavity.

[0012] As a preferred embodiment of the present invention, a one-way valve for flow from inside to outside is provided at the bottom of the second storage chamber near the connection seat.

[0013] As a preferred embodiment of the present invention, a cylindrical support rod is fixedly mounted on the outer wall of the adjustment block, and the connecting seat is provided with a clearance groove for the movement of the support rod.

[0014] As a preferred embodiment of the present invention, a through hole penetrating to the communicating groove is provided in the support rod, and a ball cap for closing the through hole is threadedly mounted on the outer end of the support rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention stores liquid food for supplying nutrition to the patient's body through the first storage cavity. Under the action of the opening and closing member, the first tube cavity is connected to the Y-shaped three-way tube, while the second tube cavity is in a closed state. The piston in the first storage cavity is pushed to generate pressure in the first storage cavity, thereby transporting the liquid food, and sending it into the gastric tube connected to the patient's stomach through the first connecting cavity and the Y-shaped three-way tube, which facilitates the patient's liquid food feeding operation.

[0016] The present invention can realize that when a patient experiences nausea, vomiting and refluxes gastric juice or liquid food, the opening and closing parts are used to ensure that the first storage chamber and the second storage chamber do not interfere with each other, thereby avoiding contamination caused by storing liquid food and facilitating the extraction of refluxed gastric juice. By adjusting the opening and closing parts, the first tube cavity and the Y-shaped three-way tube are in a closed state, and the second tube cavity is adjusted to an open state. In the second storage cavity, a negative pressure is generated in the second storage cavity by pulling the piston outward, thereby pumping the gastric juice and liquid food refluxed by the patient in the gastric tube into the second storage cavity for storage. Since the first tube cavity is in a closed state, the liquid food stored in the first storage cavity is avoided from being contaminated. Therefore, there is no need to clean the first storage cavity before feeding the patient again, which saves operation time and avoids waste of liquid food. The structure is reasonable and practical.

[0017] The present invention delivers water for cleaning equipment into the connecting groove, and then delivers or pushes water out of the first storage chamber or the second storage chamber by reciprocatingly pushing and pulling the piston in the first storage chamber or the second storage chamber, thereby achieving rapid cleaning of the first storage chamber or the second storage chamber. The present invention is simple and convenient to use, and during the cleaning process, the first storage chamber or the second storage chamber is cleaned separately and is not connected to each other, which also ensures that pollutants in the second storage chamber will not enter the first storage chamber and cause contamination.

[0020] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by those skilled in the art to which the present invention pertains. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items. Example 1:

[0022] See also Figure 1-5The present invention provides a separated liquid food feeding device for critically ill patients, comprising a main box body 1, wherein the main box body 1 is respectively provided with a first storage chamber 11 and a second storage chamber 12, wherein a push rod 13 is respectively installed in the first storage chamber 11 and the second storage chamber 12, wherein the end of the push rod 13 is provided with a piston 131 which matches the inner wall of the first storage chamber 11 or the second storage chamber 12, and a connecting seat 2 and a Y-shaped three-way pipe 21 are fixedly installed on the outer end surface of the main box body 1, wherein the connecting seat 2 is respectively provided with a first tube cavity 22 and a second tube cavity 23, wherein one end of the first tube cavity 22 and the second tube cavity 23 are respectively connected to the two branches of the Y-shaped three-way pipe 21 The tubes are connected, and the other ends of the first tube cavity 22 and the second tube cavity 23 are connected to the first storage cavity 11 and the second storage cavity 12 respectively. The main tube of the Y-shaped three-way tube 21 is connected to the gastric tube introduced into the patient's stomach. An opening and closing member for adjusting the closure or opening of the first tube cavity 22 and the second tube cavity 23 is movably installed in the connecting seat. Under the action of the opening and closing member, the first tube cavity 22 is connected to the Y-shaped three-way tube 21, and the second tube cavity 23 is in a closed state. The piston 131 in the first storage cavity 11 is pushed to generate pressure in the first storage cavity 11, thereby transporting the liquid food, which is convenient for the patient's liquid food feeding operation.

[0023] Please pay attention to Figure 2-5 The opening and closing member is a columnar adjusting block 3, which is movably installed in the connecting seat 2 in the vertical direction and rotates around the center of the connecting seat 2 in the vertical direction. The adjusting block 3 is eccentrically provided with a communicating groove 31 that penetrates the adjusting block 3. The communicating groove 31 corresponds to the position of the first tube cavity 22 and the second tube cavity 23 respectively after the adjusting block 3 rotates. By rotating the adjusting block 3, the communicating groove 31 is respectively located at the first tube cavity 22 or the second tube cavity 23, so that the first tube cavity 22 is connected to the first storage cavity 11 or the second tube cavity 23 is connected to the second storage cavity 12. At the same time, due to the eccentric design of the adjusting block 3, when one of the tube cavities is in the open state, the other tube cavity is blocked by the adjusting block 3 and is in the closed state, thereby realizing the separation of the first storage cavity 11 and the second storage cavity 12, and preventing the gastric fluid in the second storage cavity 12 from contaminating the liquid food in the first storage cavity 11.

[0024] Please pay attention to Figure 2-5 The shapes of the first tubular cavity 22, the second tubular cavity 23 and the connecting groove 31 are all circular cylindrical grooves arranged in the horizontal direction. The diameter of the inner circular groove of the first tubular cavity 22 and the second tubular cavity 23 is smaller than that of the connecting groove 31, so that liquid food or gastric juice can pass through the first tubular cavity 22 or the second tubular cavity 23 smoothly.

[0025] Please pay attention to Figure 4The cam 33 is fixed to the position where the adjusting block 3 is moved to the end of the limiting slot 24, thereby preventing the adjusting block 3 from sliding freely and affecting the operation of the equipment. Moreover, due to the elastic damping of the elastic block 241, it is possible to sense whether the limiting slot is fixed in place during operation, which is convenient for use.

[0026] Please pay attention to Figure 1 、 Figure 2 、 Figure 5 The main box body 1 is provided with an opening for adding liquid food on the outside, and a connecting cover 14 is installed at the opening. The opening of the main box body 1 extends outward with a ring tooth for installing the connecting cover 14, and the connecting cover 14 is connected to the ring tooth by a thread, so that liquid food for supplying nutrition to the patient's body can be added into the first storage chamber 11 through the opening of the main box body 1, and the sealing cover ensures the hygiene of the liquid food in the first storage chamber 11 and prevents dust in the air from contaminating the liquid food. The inner wall of the connecting cover 14 extends toward the first storage chamber 11 with a sealing plug 141 that matches the shape of the opening of the main box body 1. The outer end surface of the sealing plug 141 is flush with the inner wall of the first storage chamber 11, and the sealing of the opening of the main box body 1 is further ensured by the sealing plug 141. The end surface of the sealing plug 141 is flush with the inner wall of the first storage chamber 11, which makes it more convenient for the piston 131 in the first storage chamber 11 to push the liquid food and avoids the gap at the opening causing liquid food to leak and affect the delivery.

[0027] Please pay attention to Figure 3 、 Figure 5 A one-way valve 121 for flowing from the inside to the outside is provided at the bottom of the second storage chamber 12 near the connecting seat 2. When too much gastric fluid is stored in the second storage chamber 12, the regulating block 3 is rotated to close the second tube cavity 23, and the gastric fluid in the second storage chamber 12 is quickly discharged through the one-way valve 121.

[0028] Please pay attention to Figure 1-5 A cylindrical support rod 32 is fixedly installed on the outer wall of the adjustment block 3, and the connecting seat 2 is provided with a makeshift groove 25 for moving the support rod 32. The support rod 32 is used to easily push the adjustment block 3 to rotate, making it convenient for users to perform adjustment operations.

[0029] The specific operation method of the first embodiment of the present invention is as follows: When feeding the patient, the pull rod is pulled outward to pull the piston 131 in the first storage chamber 11 to the rear end of the main box body 1, and the connecting cover 14 on the top of the main box body 1 is removed. The liquid food for supplying nutrition to the patient's body is added into the first storage chamber 11 from the opening at the top of the main box body 1, and the sealing plug 141 in the middle part of the connecting cover 14 is aligned with the opening of the main box body 1 and inserted. The connecting cover 14 is rotated to drive the sealing plug 141 to move toward the first storage chamber 11 under the threaded connection, and the connecting cover 14 is tightly fixed to the main box body 1 through the thread. When the connecting cover 14 is fixed, the outer end surface of the sealing plug 141 is flush with the inner wall of the first storage chamber 11. The gastric tube connected to the patient's stomach is inserted into the Y-shaped three-way tube 21 to connect the gastric tube with the main tube of the Y-shaped three-way tube 21, and the support rod 32 is pushed to rotate the adjusting block 3 so that the communicating groove 31 is aligned with the first tube cavity 22 and matches the first tube cavity 22. At the same time, the limiting pin 33 slides in the limiting slide groove 24 to the end position of the upper part of the limiting slide groove 24, and the limiting pin 33 is pressed and fixed by the elastic block 241. At this time, the first storage chamber 11 and the first tube cavity 22 are in a communicating state, and the second storage chamber 12 is in a closed state due to the blockage of the adjusting block 3, pushing the push rod 13 in the first storage chamber 11 inward, thereby driving the piston 131 in the first storage chamber 11 When the patient vomits or refluxes gastric juice or liquid food, the regulating block 3 is rotated by the support rod 32 to move the communicating groove 31 to the second lumen 23 and coincide with the second lumen 23. The second lumen 23 and the second storage chamber 12 are in a communicating state. The push rod 13 in the second storage chamber 12 is pulled outward, and the push rod 13 drives the piston 131 in the second storage chamber 12 to move toward the tail of the main box body 1. Due to the movement of the piston 131, negative air pressure is generated in the cavity 12. The negative air pressure is transmitted to the Y-shaped three-way tube 21 and the gastric tube connected to the Y-shaped three-way tube 21 through the second tube cavity 23 and the connecting groove 31. Under the suction of negative pressure, the patient's gastric juice and vomited liquid food are pumped into the second storage cavity 12. It is convenient and fast to use. At this time, the first storage cavity 11 is in a closed state due to the blockage of the adjustment block 3. The withdrawn gastric juice and vomited liquid food will not flow into the first storage cavity 11 and cause contamination to the stored liquid food. When the patient's gastric juice and liquid food are pumped out, the first tube cavity 22 is opened by rotating the adjustment block 3, and clean liquid food can continue to be fed to the patient. Example 2:

[0030] Please pay attention to Figure 2-5The support rod 32 is provided with a through hole 321 that passes through the communicating groove 31, and the outer end of the support rod 32 is threadedly installed with a ball cap 322 for closing the through hole 321. By connecting a water pipe to the top of the support rod 32, it is convenient to transport water used for cleaning the equipment through the through hole 321 to the communicating groove 31. At this time, the water is transported or pushed out of the first storage chamber 11 or the second storage chamber 12 by reciprocatingly pushing and pulling the piston 131 in the first storage chamber 11 or the second storage chamber 12, thereby quickly cleaning the first storage chamber 11 or the second storage chamber 12. It is simple and convenient to use, and during the cleaning process, the first storage chamber 11 or the second storage chamber 12 are cleaned separately and are not connected to each other, which also ensures that the pollutants in the second storage chamber 12 will not enter the first storage chamber 11 and cause pollution.

[0031] The specific operation method of the second embodiment of the present invention is as follows: When it is necessary to clean the inside of the main box body 1, the ball cap 322 on the rotating support rod 32 is removed from the support rod 32, the water pipe connected to the water source is connected to the support rod 32, and the adjusting block 3 is rotated to make the connecting groove 31 coincide with the first cavity. At this time, the connecting groove 31 and the first storage chamber 11 are in a connected state, and the water source is turned on. The cleaning water enters the connecting groove 31 through the water pipe and the through hole 321 of the support rod 32. At this time, the push rod 13 at the first storage chamber 11 is manually pushed and pulled to make the piston 131 at the end of the push rod 13 move back and forth in the first storage chamber 11. Negative pressure is continuously generated in the storage chamber 11 to pump the water in the connecting groove 31 into the first storage chamber 11, and the cleaned water is continuously pushed into the first tube cavity 22 and discharged through the main pipe of the Y-shaped three-way pipe 21. The cyclic operation can quickly clean the first storage chamber 11; after the first storage chamber 11 is cleaned, the adjusting block 3 is rotated to align the connecting groove 31 with the second cavity, and the push rod 13 at the second storage chamber 12 is pushed and pulled back and forth to drive the piston 131 in the second storage chamber 12 to move back and forth, so that the second storage chamber 12 can be quickly cleaned. The operation is simple and convenient, and it is practical.

[0032] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
