Description

Technical Field

[0001] The invention belongs to the technical field of hemodialysis equipment, in particular to a hemodialysis concentrate barrel and a hemodialysis concentrate conveying device. Background Art

[0002] Hemodialysis is an alternative treatment method used to purify blood in patients with chronic kidney disease or acute renal failure. The therapy uses a device called a dialysis machine to introduce the patient's blood into a semi-permeable membrane bag, and then discharges waste and excess water in the blood through the semi-permeable membrane. Existing hemodialysis fluid concentrate barrels are inconvenient to use. The concentrate inside is easily spilled during the pouring process, resulting in waste of concentrate, and it is easy to be contaminated with germs or harmful substances in the air. The safety of use is poor and it is easy to endanger the life and health of patients.

[0003] In order to solve the above problems, for example, a Chinese patent, publication number: CN 106904564 A, discloses a hemodialysis concentrate barrel and a hemodialysis concentrate delivery device, including a concentrate barrel cover, a concentrate barrel, a bracket fixing connecting sleeve, a concentrate pump and a tube head fixing sealing sleeve, wherein a concentrate barrel base is provided at the bottom of the concentrate barrel, and a liquid level observation window is provided at the middle position of the front surface of the concentrate barrel, a concentrate barrel lifting handle is provided at one end above the concentrate barrel, and a concentrate barrel opening is provided at one end above the concentrate barrel away from the concentrate barrel lifting handle, the concentrate barrel cover is installed above the concentrate barrel opening, the bracket fixing connecting sleeve is installed on the concentrate barrel, and a connecting sleeve fixing bolt is provided on one side of the bracket fixing connecting sleeve; the bracket fixing connecting sleeve connects the concentrate pump to the concentrate barrel, thereby avoiding the inconvenience of pouring the concentrate from the concentrate barrel, and avoiding the problem of spilling and wasting the concentrate during the pouring and delivery of the concentrate, thereby saving the concentrate.

[0004] However, in actual use, dust may enter the concentrate through the barrel mouth and cause the concentrate to be contaminated, which may affect health; the concentrate is easily contaminated when exposed for a long time; there is a risk of cross contamination when the barrel is reused; bubbles may be generated in the concentrate during transportation, which may be transferred to the patient's body and cause embolism. Therefore, the present invention proposes a hemodialysis concentrate barrel and a hemodialysis concentrate delivery device that can reduce bubbles and avoid contamination to a certain extent. Summary of the invention

[0005] The present invention provides a hemodialysis concentrate barrel and a hemodialysis concentrate conveying device, which reduce bubbles generated during transportation and also avoid the occurrence of concentrate contamination to a certain extent.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A hemodialysis concentrate bucket includes a bucket body. Liquid inlet and liquid outlet are respectively provided on both side walls of the bucket body. The liquid inlet and the liquid outlet are both thread-sealed and connected with covers. The liquid inlet and the liquid outlet are respectively fixedly connected with a liquid inlet pipe and a liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe both penetrate through the side wall of the bucket body. One end of the liquid inlet pipe located outside the bucket body is communicated with a filter, and the other end of the liquid inlet pipe is communicated with a liquid storage bag. One side of the liquid storage bag far away from the liquid inlet pipe is communicated with the liquid outlet pipe. A one-way valve is provided at the connection between the liquid inlet pipe and the liquid storage bag. A support plate is fixedly connected to the outer side wall of the bottom of the liquid storage belt. A plurality of support rods are fixedly connected to one side of the support plate far away from the liquid storage bag. One end of the support rod far away from the support plate is fixedly connected to the inner side wall of the bottom of the bucket body.

[0007] After adopting the above solution, the following beneficial effects are achieved: When filling the hemodialysis concentrate, the cover on the liquid inlet is opened, and the hemodialysis concentrate flows from the liquid inlet through the liquid inlet pipe into the liquid storage bag. When flowing through the liquid inlet pipe, the filter on the liquid inlet pipe can initially filter the bubbles in the hemodialysis concentrate. When the hemodialysis concentrate enters the liquid storage bag, the liquid storage bag is slowly filled and expanded by the hemodialysis concentrate. When there is no concentrate entering, the liquid storage bag is close to the support plate and there is no air inside. When filling to the required amount, the one-way valve on the liquid inlet pipe and the cover on the liquid inlet are closed, and the hemodialysis concentrate can be output through the liquid outlet pipe and flow into the hemodialysis machine. The covers on the liquid inlet and the liquid outlet can prevent foreign matters from entering the liquid storage bag from the liquid inlet and the liquid outlet during filling and transportation, thus contaminating the hemodialysis concentrate.

[0008] In summary, this solution receives the hemodialysis concentrate through the liquid storage bag, reduces the height difference of the hemodialysis concentrate entering the bucket body, and squeezes the liquid storage bag during use to output the concentrate into the hemodialysis machine, avoiding the generation of bubbles, and to a certain extent, it can avoid the generation of embolism phenomena, and also to a certain extent, it can avoid the generation of the phenomenon of concentrate being contaminated.

[0009] Further, the support plate is of an inclined structure, and the support rod on the side close to the liquid outlet is lower than the support rod on the side close to the liquid inlet.

[0010] Beneficial effect: The support plate is of an inclined structure, so that the concentrate transported to the liquid storage bag will automatically flow towards the liquid outlet pipe according to its own gravity.

[0011] Further, the support rod is of an elastic member structure, and a window and a transparent layer for closing the window are provided on the lower part of the side wall of the bucket body.

[0012] Beneficial effect: Medical staff can observe the compression degree of the elastic member through the transparent layer, and at the same time judge the filling amount of the hemodialysis concentrate in the liquid storage bag according to the compression degree, so that the liquid can be taken as needed, reducing the loss and waste of the concentrate.

[0013] Furthermore, a thermostat is provided inside the support plate.

[0014] Beneficial effects: When transporting the hemodialysis concentrate in the liquid storage bag to the hemodialysis machine, the thermostat is turned on to keep the temperature of the concentrate in the liquid storage bag around 37°C, because the normal value of the temperature of the hemodialysis concentrate is 35°C - 39°C.

[0015] Furthermore, a base is provided at the bottom of the barrel body. The barrel body is placed on the base. A roller is fixedly connected to the bottom of the base. The roller is a universal wheel structure with a brake. A push rod is fixedly connected to the side wall of the base.

[0016] Beneficial effects: When it is necessary to carry the barrel of hemodialysis concentrate, medical staff can push the barrel body through the push rod and the universal wheel, which increases the convenience and practicality of the barrel of hemodialysis concentrate to a certain extent, reduces accidental injuries of medical staff during work, and improves the work efficiency of medical staff.

[0017] A hemodialysis concentrate delivery device includes a connecting pipe. A storage box is fixedly connected to the outer side wall of the top of the barrel body. A power component is fixedly connected to the center position of the inner bottom wall of the storage box. The output shaft of the power component penetrates through the bottom wall of the storage box and the top wall of the barrel body and is coaxially fixedly connected with a connecting rod. One end of the connecting rod away from the power component is fixedly connected with a pressing plate. Openings are provided on both side walls of the storage box. Lids are hinged to the top walls of the openings. The connecting pipe is placed inside the storage box.

[0018] Beneficial effects: When it is necessary to fill the hemodialysis concentrate, open the lid, take out the connecting pipe from the storage box, open the lid of the liquid inlet on the barrel body, connect the connecting pipe to the liquid inlet, and let the hemodialysis concentrate flow through the connecting pipe from the liquid inlet through the liquid inlet pipe into the liquid storage bag in the barrel body; when it is necessary to deliver the hemodialysis concentrate, connect the connecting pipe to the liquid outlet, start the power component, the power component pushes the pressing plate, and the pressing plate and the support plate squeeze the liquid storage bag, so that the hemodialysis concentrate in the liquid storage bag flows through the liquid outlet pipe from the liquid outlet and the connecting pipe to the hemodialysis device; after use, remove the connecting pipe, and after cleaning and disinfection, place it back inside the storage box and close the lid to avoid contamination of the connecting pipe during idling.

[0019] Furthermore, several rotating rods are provided on the inner bottom wall of the storage box. One end of the rotating rod is rotatably matched with the bottom wall of the storage box. The other end of the rotating rod penetrates through the top wall of the storage box and is fixedly connected with a handle. The center of the connecting pipe is fixedly connected to the middle of the rotating rod. The two ends of the connecting pipe are respectively wound around the two ends of the rotating rod.

[0020] Beneficial effects: placing the connecting tube in the storage box is inconvenient for storage, and during use, the connecting tube is easy to fold, thereby affecting the delivery of hemodialysis concentrate. The connecting tube is wound around the rotating stick and the length of the connecting tube is controlled by rotating the handle, which also makes the storage of the connecting tube more convenient; when the connecting tube needs to be used, the handle is rotated to unwind the connecting tube on the rotating stick, and the hemodialysis concentrate is infused into the barrel body or discharged from the barrel body through the connecting tube; after use, the connecting tube can be wound around the rotating stick by simply rotating the handle in the opposite direction, making storage more convenient and neat.

[0021] Furthermore, a plurality of hooks are fixedly connected to the inner sides of the bottom wall and the top wall of the storage box.

[0022] Beneficial effect: When the connecting tube is wrapped around the rotating rod for storage, the two ends of the connecting tube can be fixed on the hooks on the inner sides of the bottom wall and the top wall respectively, which fixes the connecting tube and prevents the connecting tube from falling off the rotating rod during transportation.

[0023] Furthermore, the extrusion plate is an inclined structure, and the extrusion plate on the side close to the liquid outlet is lower than the extrusion plate on the side close to the liquid inlet.

[0024] Beneficial effect: the extrusion plate is an inclined structure, which is aligned with the support plate, and can squeeze the liquid storage bag more fully. BRIEF DESCRIPTION OF THE DRAWINGS

Liquid inlets 2 and liquid outlets 3 are respectively provided on both side walls of the barrel body 1. The liquid inlets 2 and the liquid outlets 3 are both thread-sealed and connected with cover bodies 101. The liquid inlets 2 and the liquid outlets 3 are respectively fixedly connected with liquid inlet pipes 201 and liquid outlet pipes 301. The liquid inlet pipes 201 and the liquid outlet pipes 301 both penetrate through the side wall of the barrel body 1. One end of the liquid inlet pipe 201 located outside the barrel body 1 is communicated with a filter 202. The other end of the liquid inlet pipe 201 is communicated with a liquid storage bag 4. One side of the liquid storage bag 4 away from the liquid inlet pipe 201 is communicated with the liquid outlet pipe 301. A one-way valve is provided at the connection of the liquid inlet pipe 201.
