DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Specific examples are given below.

[0032] See also Figure 1-6As shown, a nursing trolley comprises a trolley body 11; a bottom plate 12 is fixedly connected to the bottom of the trolley body 11; a group of storage cylinders 13 are provided on the bottom plate 12; a vertical tube 14 is slidably connected to the middle of the storage cylinder 13; a plurality of through slots are opened at the bottom end of the vertical tube 14; a pipe connecting tube 15 is fixedly connected to the top of the vertical tube 14; a cannula 16 is provided on the top of the pipe connecting tube 15; a first tube body 17 is fixedly connected to the top of the cannula 16; a collecting tube 18 is fixedly connected to the top of the first tube body 17; a cover body 19 is fixedly connected to the top of the collecting tube 18; straps are fixedly connected to both sides of the cover body 19; the first tube body 17 is a hose; when in use, it is inconvenient to collect vomit through the container on the trolley body 11, and the nursing staff needs to bring it to the patient in time, and the vomitus that splashes will splash, Then the ground and bedding will be soiled. When the embodiment of the present invention is in use, the medical staff covers the patient's lips and face with the mask body 19 without covering the nose, and then fixes it with a strap. When the patient vomits, the vomit directly enters the mask body 19, and then is injected into the storage cylinder 13 through the collecting cylinder 18, the first tube body 17 and the vertical tube 14, and flows out from the through groove at the bottom of the vertical tube 14 to collect the vomit. When vomiting occurs multiple times, the medical staff only needs to replace the storage cylinder 13. Relying on the above-mentioned arrangement, during use, it is only necessary to control the patient so that his face is facing down, without the need for large body movements, so that it is convenient for nursing staff with weaker physical strength to perform patient care. At the same time, small body movements can reduce the situation of pulling the wounds on the patient's body and reduce the situation of vomit splashing and soiling the ground and bedding.

[0033] Further, such as Figure 2-3As shown, the top side of the bottom plate 12 is fixedly connected to a stepper motor 21; the output shaft of the stepper motor 21 is fixedly connected to a rotating shaft 211; the rotating shaft 211 passes through the bottom plate 12 and is rotatably connected thereto; the top and bottom surfaces of the rotating shaft 211 are respectively fixedly connected to a top frame 22 and a bottom frame; the bottom frame and the top frame 22 are both located inside the trolley body; a plurality of storage cylinders 13 are provided; the storage cylinder 13 passes through the top frame 22 and is slidably connected to the top frame 22 and the bottom frame; an electric push rod 23 is fixedly connected to the inner side wall of the trolley body 11; the output end of the electric push rod 23 is fixedly connected to a connecting plate 24; the connecting plate 24 is fixedly connected to the intubation tube 16; the vertical tube 14 The bottom end is fixed with a piston plate; a pressure sensor is installed on the inner wall of the collecting cylinder 18; when in use, the patient's vomit will flow from the cover 19 into the collecting cylinder 18, accumulate in the collecting cylinder 18, and then trigger the pressure sensor, so that the electric push rod 23 is energized to work, thereby driving the connecting plate 24 and the cannula 16 to move downward, and the cannula 16 will squeeze and push the vertical tube 14 and the piston plate to slide downward, and negative pressure will be generated in the rod cavity of the storage cylinder 13, so that the vomit can quickly flow from the collecting cylinder 18 and the vertical tube 14, which are used to transport vomit, and then flow out from the through groove into the interior of the storage cylinder 13, and be sucked by the negative pressure. Thereby, the accumulation of vomitus can be reduced, and the force of applying a negative pressure suction can make it less likely to be blocked than the natural downward flow. After the vomitus is sucked, the electric push rod 23 drives the connecting plate 24 and the cannula 16 to reset upward, and then the stepper motor 21 drives the top frame 22 and the bottom frame to rotate, switching the next storage cylinder 13, and then the electric push rod 23 drives the top plate to move downward a certain distance, so that the cannula 16 is inserted into the pipe connecting tube 15 to connect it. The pipe connecting tube 15 is provided with a seal for sealing. Relying on the above settings, different storage cylinders 13 are automatically switched to facilitate the classified storage of the patient's multiple vomitus. This makes it easier for doctors to analyze the patient's condition and record corresponding data based on the patient's vomit. After the storage cylinder 13 is used up, the nurse can pull out the storage cylinder 13 from the bottom frame and send it for testing, and then insert a new storage cylinder 13 from the top frame 22 downward; a spring can be installed under the piston plate to assist the vertical pipe 14 in resetting, and an exhaust valve is installed at the bottom of the storage cylinder 13. When the piston plate moves downward, the air in the storage cylinder 13 is discharged from the exhaust valve. When the vomit needs to be squeezed out for analysis, the exhaust valve is opened to allow outside air to enter the interior of the storage cylinder 13 from the exhaust valve, and the spring installed under the piston plate drives the piston plate to reset.

[0034] Further, such as Figure 2 、 3As shown in , 6 and 7, a small air pump 31 is fixedly connected to the inner side wall of the trolley body 11; the output end of the small air pump 31 is fixedly connected to an air tube 32; the air tube 32 is a hose; the side of the cover body 19 is fixedly connected to a ring body 33; the top end of the air tube 32 passes through the ring body 33 and is fixed thereto; the side of the ring body 33 away from the cover body 19 is fixedly connected to an air bag cover 34; the air bag cover 34; the top end of the air tube 32 is inserted into the interior of the air bag cover 34; when in use, the small air pump 31 and the air tube 32 are started to fill the air into the air bag cover 34 so that it can expand. A pressure gauge connected to the air bag cover 34 can be installed on the cover body 19, or the small air pump 31 can be turned off by visual observation. The expanded air bag cover 34 can fill the gap between the patient's skin and the ring body 33. The air bag cover 34 is made of rubber and can play a sealing role, thereby reducing the leakage of patient vomit.

[0035] Further, such as Figure 5-7 As shown, a flushing cylinder 43 is fixedly connected to the middle part of the side of the cover body 19 away from the ring body 33; a sliding groove is provided in the flushing cylinder 43; the end of the sliding groove close to the ring body 33 is designed in a trumpet-shaped structure; a group of limit blocks 46 are fixedly connected to the end of the sliding groove close to the ring body 33; a water retaining ring 45 is slidably connected to the inside of the sliding groove; a flushing pipe 44 is fixedly connected to the inner side wall of the water retaining ring 45; a water pipe 42 is fixedly connected to the end of the flushing cylinder 43 away from the ring body 33; a water tank 41 is fixedly connected to the inner side wall of the trolley body 11; a submersible pump is installed in the water tank 41; the output end of the submersible pump is fixedly connected to the water pipe 42; the water pipe 42 is a hose; when in use, clean water is injected into the water tank 41, and then the clean water will flow The water is injected into the water pipe 42 through the water pump and then enters the flushing cylinder 43. Since the diameter of the flushing pipe 44 is smaller than the water pipe 42, the water pressure will push the water retaining pipe 42 to slide in the flushing cylinder 43, and then the flushing pipe 44 will move toward the patient's mouth, so that its end can extend into the patient's mouth to clean the vomit residue in the patient's mouth. The water retaining ring 45 will move all the way to the end of the sliding groove and then be blocked by the limit block 46. The water will be sprayed out from the gap between the sliding groove and the water retaining ring 45, so that the cover body 19, the collection cylinder 18 and the first tube body 17 can be flushed, thereby reducing the vomit adhering to the inner wall of the cover body 19 and the collection cylinder 18, thereby reducing the growth of bacteria in the cover body 19 and the collection, and reducing odor.

[0036] Further, such as Figure 5-7As shown, one end of the flushing pipe 44 close to the ring body 33 is rotatably connected to a water outlet cylinder 52; a group of water outlet grooves are opened on the water outlet cylinder 52; the inner side wall of the water outlet cylinder 52 is fixedly connected to a plurality of rod bodies; one end of the plurality of rod bodies away from the ring body 33 is fixedly connected to an impeller 51; the impeller 51 is sleeved on the surface of the flushing pipe 44 and slidably connected thereto, and the water outlet groove is an L-shaped groove; the impeller 51 is located on the side of the limit block 46 away from the water retaining ring 45; the impeller 51 is located inside the sliding groove; when in use, the water flow is injected into the water outlet cylinder 52 from the sliding groove, and the impact of the water flow will drive the impeller 51 to rotate, and the rotation of the impeller 51 will drive the flushing cylinder 43 to rotate, and the rotation of the impeller 51 will drive the water outlet groove on the water outlet cylinder 52 to spray outward through the rod body. Relying on the rotating water outlet cylinder 52 and the L-shaped water outlet groove, the flushing area inside the cover body 19 can be increased, thereby improving the overall cleaning effect.

[0037] Further, such as Figure 2-4 As shown, the bottom of the bottom plate 12 is fixedly connected to a waste water tank 61; the waste water tank 61 is fixedly connected to a drain valve and a plurality of second tube bodies; the second tube body passes through the bottom plate 12, the bottom frame and the top frame 22 and is slidably connected thereto; the top end of the second tube body is fixedly connected to a connecting tube 63; the top ends of the pipe connecting tube 15 and the connecting tube 63 are fixedly connected to a cylinder 62; the inner side wall of the cylinder 62 is fixedly connected to a plurality of spring pieces 64 fixedly connected to the surrounding array; the inner side wall of the cylinder 62 is fixedly connected to an elastic membrane 65; the spring piece 64 is located between the elastic membrane 65 and the cylinder 62; the second tube body is a hose; a plurality of brackets are fixedly connected to the cylinder 62; the bracket is fixedly connected to the rotating shaft 211; the spring piece 64 is designed in a V-shaped structure; the cross-section of the cylinder 62 is designed in a U-shaped structure; before flushing the inside of the cover body 19, the stepping motor 21 drives the rotating shaft 211 and the top The frame 22 rotates so that the connecting tube 63 corresponds to the position of the cannula 16, and then the electric push rod 23 is controlled to drive the cannula 16 to be inserted into the interior of the connecting tube 63, so that the first tube body 17 is connected with the third tube and the waste water tank 61, and then the flushing waste water can enter the waste water tank 61, so as to collect the waste water, which is convenient for the nursing staff to carry out centralized treatment. The pipe connecting tube 15 and the connecting tube 63 have the same structure. In the process of inserting the cannula 16 into the pipe connecting tube 15, the bottom of the cannula 16 will squeeze the elastic membrane 65, causing the spring 64 to bend, and then the elastic membrane 65 opens, so that the cannula 16 can pass through the elastic membrane 65 and move downward. When the cannula 16 is pulled out, under the action of the spring 64, the elastic membrane 65 is restored, so that the cylinder body 62 can be sealed, thereby reducing the odor in the waste water tank 61 and the storage cylinder 13.

[0038] Further, such as Figure 6-8As shown, a diffusion chamber 71 is provided at one end of the flushing tube 44 away from the water retaining ring 45; a porous cover 72 is fixedly connected to one end of the diffusion chamber 71 away from the water retaining ring 45; a silicone ring 73 is fixedly connected to one end of the flushing tube 44 away from the water retaining ring 45; a rubber ring 74 is fixedly connected to the water retaining ring 45; a support spring is fixedly connected between the limit block 46 and the water retaining ring 45; when in use, since the water flow in the flushing cylinder 43 can drive the impeller 51 to rotate and the water retaining ring 45 to slide, the water flow needs to have a large pressure, which in turn causes the water flow pressure sprayed out of the flushing tube 44 to be large. During use, the embodiment of the present invention provides a diffusion chamber 71 and a porous cover 72 at the end of the flushing tube 44 to reduce the pressure of the water outlet, and provides the porous cover 72 to increase the flushing area. The silicone ring 73 is used to buffer the contact between the sliding flushing tube 44 and the patient's skin, and the rubber ring 74 is used to provide friction damping of the water retaining ring 45 to reduce the sliding speed of the flushing tube 44. The support spring is used to reset the flushing tube 44 after cleaning is completed.

[0039] Further, such as Figure 8-9 As shown, the two sides of the ring body 33 are fixed to the valve body 81; a valve block 82 is slidably connected to the valve body 81; a group of air holes are opened on the side of the valve body 81 close to the airbag cover 34; a plurality of return springs are fixedly connected between the valve block 82 and the inner wall of the valve body 81; a pull rope 83 is fixedly connected to the side of the valve block 82; the pull rope 83 passes through the valve body 81 and is slidably connected thereto; the end of the pull rope 83 away from the valve block 82 is fixedly connected to the plate body; the plate body is rotatably connected to the flushing cylinder 43; when in use, the staff can rotate the plate body to pull the valve block 82 to slide through the pull rope 83, so that the gas inside the airbag cover 34 can enter the valve body 81 through the air holes, and then turn on the small air pump 31, and the air flow is sprayed into the valve body 81, so that the valve body 81 can be dried by the air flow, thereby inhibiting the growth of bacteria in the cover body 19 and reducing the odor emitted by the large amount of bacteria.

[0040] Further, such as Figure 9As shown, a fitting ring 91 is fixedly connected to the side of the ring body 33 away from the cover body 19; a curved surface is opened on the side of the fitting ring 91 away from the ring body 33; an elastic rope 92 is fixedly connected between the side wall of the fitting ring 91 and the inner side wall of the airbag cover 34; a pair of suction cup frames 84 are fixedly connected to the side of the cover body 19 close to the ring body 33; when in use, the cleaning water in the cover body 19 will penetrate into the surface of the airbag cover 34. Over a long period of time, a small amount of water will cause a large number of bacteria to grow. In the embodiment of the present invention, the valve body 81 is opened. During the opening process, the suction cup frame 84 will come into contact with the patient's face and press against the patient's face, so that there is a certain gap between the airbag cover 34 and the patient's face for the gas to be ejected outward, and then the elastic rope 92 will pull the airbag cover 34 to make it come into contact with the arc surface of the fitting ring 91. The air flow will flow outward along the arc surface, and one side can dry the surface of the airbag cover 34 to keep the part where the airbag cover 34 fits the skin dry. The suction cup frame 84 can be installed with a suction cup to quickly fix the mask body 19 on the patient's face.

[0041] Further, such as Figure 7 As shown, the cover body 19 is fixed with an air inlet cylinder 101; the inner wall of the air inlet cylinder 101 at one end close to the valve body 81 is slidably connected with a sealing plug 102; an elastic member is fixed between the sealing plug 102 and the inner wall of the air inlet cylinder 101; when in use, the amount of vomitus of the patient is different each time, so the capacity of the storage cylinder 13 needs to be larger, but after the liquid in the collection cylinder 18 is discharged, the negative pressure in the storage cylinder 13 draws the air in the collection cylinder 18 and the cover body 19, and the cover body 19 will excessively squeeze the patient's face. When the embodiment of the present invention is in use, when the negative pressure in the collection cylinder 18 is large, the sealing plug 102 will be rushed into the air cylinder 101 and pulled out, so that the external air rushes into the air cylinder 101 and quickly enters the interior of the collection cylinder 18, maintaining the air pressure in the air inlet cylinder 101, thereby reducing the situation where the negative pressure in the cover body 19 excessively adsorbs the patient's face.

[0042] Working principle: when in use, it is inconvenient to collect vomit through the container on the trolley body 11, and the nursing staff needs to bring it to the patient in time, and the splashed vomit will splash, thereby dirtying the ground and the bed. When the embodiment of the present invention is in use, the medical staff covers the patient's lips and face with the mask 19 without covering the nose, and then fixes it with a strap. When the patient vomits, the vomit directly enters the mask 19, and then is injected into the storage cylinder 13 through the collection cylinder 18, the first tube 17 and the vertical tube 14, so as to collect the vomit. When vomiting occurs multiple times, the medical staff only needs to replace the storage cylinder 13. Relying on the above-mentioned arrangement, during use, it is only necessary to control the patient so that his face is facing down, without the need for large limbs. The vomitus of the patient will flow from the cover 19 into the collecting tube 18 and accumulate in the collecting tube 18, thereby triggering the pressure sensor to energize the electric push rod 23 to work, thereby driving the connecting plate 24 and the cannula 16 to move downward, and the cannula 16 will squeeze and push the vertical tube 14 and the piston plate to slide downward, and negative pressure will be generated in the rod cavity of the storage tube 13, so that the vomitus can quickly flow from the collecting tube 18 and the vertical tube 14, and then flow out from the through groove into the interior of the storage tube 13, and be sucked by the negative pressure, thereby reducing the accumulation of vomitus. The collection situation, and relying on the force of applying a negative pressure to absorb it, compared with the natural downward flow, it can make it less likely to be blocked. After the vomit is absorbed, the electric push rod 23 drives the connecting plate 24 and the cannula 16 to reset upward, and then the stepping motor 21 drives the top frame 22 and the bottom frame to rotate, switching the next storage cylinder 13, and then the electric push rod 23 drives the top plate to move downward a certain distance, so that the cannula 16 is inserted into the pipe connecting tube 15 to connect it. A sealing member is provided in the pipe connecting tube 15 for sealing. Relying on the above setting, different storage cylinders 13 are automatically switched to facilitate the classification and storage of the patient's multiple vomitus, so that the doctor can analyze the patient's condition and record the corresponding data according to the patient's vomitus, start the small air pump 31 and The trachea 32 fills gas into the airbag sleeve 34 to make it expand. A pressure gauge connected to the airbag sleeve 34 can be installed on the mask body 19, or the small air pump 31 can be turned off by visual observation. The expanded airbag sleeve 34 can fill the gap between the patient's skin and the ring body 33. The airbag sleeve 34 is made of rubber and can play a sealing role, thereby reducing the leakage of the patient's vomit. When in use, clean water is injected into the water tank 41, and then the clean water is injected into the water pipe 42 through the water pump, and then enters the flushing cylinder 43. Since the diameter of the flushing pipe 44 is smaller than the water pipe 42, the water flow pressure will push the water retaining pipe 42 to slide in the flushing cylinder 43, thereby moving the flushing pipe 44 into the patient's mouth so that its end can extend into the patient's mouth.To clean the vomit residue in the patient's mouth, the water retaining ring 45 will move to the end of the sliding groove and then be blocked by the limit block 46. The water will be sprayed out from the gap between the sliding groove and the water retaining ring 45, so as to rinse the cover body 19, the collecting cylinder 18 and the first tube body 17, thereby reducing the vomit adhering to the inner wall of the cover body 19 and the collecting cylinder 18, thereby reducing the breeding of bacteria in the cover body 19 and the collection, and reducing odor. In the process of water flowing from the sliding groove to the water outlet cylinder 52, the impact of the water flow will drive the impeller 51 to rotate, and the rotation of the impeller 51 will drive the flushing cylinder 43 to rotate. The rotation of the impeller 51 will drive the water outlet groove on the water outlet cylinder 52 to spray outward through the rod body. Relying on the rotating water outlet cylinder 52 and the L-shaped water outlet groove, it can The flushing area inside the cover body 19 is increased, thereby improving the overall cleaning effect. Before flushing the inside of the cover body 19, the stepper motor 21 drives the rotating shaft 211 and the top frame 22 to rotate, so that the connecting tube 63 corresponds to the position of the cannula 16, and then controls the electric push rod 23 to drive the cannula 16 to be inserted into the inside of the connecting tube 63, so that the first tube body 17 is connected with the third tube and the waste water tank 61, and then the flushed waste water can enter the waste water tank 61, thereby collecting the waste water, which is convenient for nursing staff to carry out centralized treatment. The pipe connecting tube 15 and the connecting tube 63 have the same structure. In the process of inserting the cannula 16 into the pipe connecting tube 15, the bottom of the cannula 16 will squeeze the elastic membrane 65, causing the spring 64 to bend, and then the elastic membrane 65 is stretched. The cannula 16 is opened so that it can pass through the elastic membrane 65 and move downward. When the cannula 16 is pulled out, the elastic membrane 65 is restored under the action of the shrapnel 64, so that the cylinder body 62 can be sealed, thereby reducing the odor in the waste water tank 61 and the storage cylinder 13. When in use, since the water flow in the flushing cylinder 43 can drive the impeller 51 to rotate and the water retaining ring 45 to slide, the water flow needs to have a larger pressure, which leads to a larger pressure of the water flow sprayed out of the flushing pipe 44. During use, the embodiment of the present invention provides a diffusion chamber 71 and a porous cover 72 at the end of the flushing pipe 44 to reduce the pressure of the water outlet, and provides the porous cover 72 to increase the flushing area. The silicone ring 73 is used to buffer the sliding flushing pipe 44 and the patient's skin. The rubber ring 74 is used to provide friction damping of the water retaining ring 45, reducing the sliding speed of the flushing pipe 44. The support spring is used to reset the flushing pipe 44 after cleaning is completed. The staff can rotate the plate to pull the valve block 82 to slide through the pull rope 83, so that the gas inside the airbag cover 34 can enter the valve body 81 through the air hole, and then turn on the small air pump 31, and the air flow is sprayed into the valve body 81. In this way, the valve body 81 can be dried by the air flow, which can inhibit the growth of bacteria in the cover body 19 and reduce the odor emitted by the large-scale growth of bacteria. The cleaning water in the cover body 19 will penetrate into the surface of the airbag cover 34. Over a long period of time, a small amount of water will cause a large number of bacteria to grow. In the process of opening the valve body 81 of the embodiment of the present invention,The suction cup frame 84 will contact the patient's face and press against the patient's face, so that there is a certain gap between the air bag cover 34 and the patient's face for the gas to be ejected outwards. Then the elastic rope 92 will pull the air bag cover 34 to make it contact with the arc surface of the fitting ring 91. The air flow will flow outwards along the arc surface. One side can dry the surface of the air bag cover 34 to keep the air bag cover 34 dry at the point where it fits the skin. The suction cup frame 84 can be installed with a suction cup to quickly fix the mask body 19 on the patient's face. The amount of vomitus of the patient each time is different, so a storage cartridge 1 is required. 3 has a large capacity, but after the liquid in the collection cylinder 18 is completely drained, the negative pressure in the storage cylinder 13 draws air from the collection cylinder 18 and the mask 19, causing the mask 19 to excessively squeeze the patient's face. When the embodiment of the present invention is in use, when the negative pressure in the collection cylinder 18 is high, the sealing plug 102 will be pulled into the air cylinder 101, allowing external air to rush into the air cylinder 101 and quickly enter the interior of the collection cylinder 18, maintaining the air pressure in the air cylinder 101, thereby reducing the situation where the negative pressure in the mask 19 excessively squeezes the patient's face.
