Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a dialysate barrel. Background Art

[0002] Hemodialysis is an important treatment method for patients with renal failure. When preparing dialysate, different A liquid and B liquid are usually prepared in sequence, and they are prepared and used immediately through the hemodialysis machine. Usually, aluminum foil is set at the mouth of the barrel used to hold the dialysis concentrate to seal the dialysis concentrate, but the aluminum foil is difficult to tear open. Medical staff often use instruments such as hemostatic forceps to open the aluminum foil, but the diameter of the opening of the aluminum foil is often larger than the diameter of the dialysis fluid straw. Dust and bacteria can easily enter the dialysate barrel from the gap between the dialysis fluid straw and the aluminum foil, thereby contaminating the dialysis concentrate.

[0003] When inserting the dialysate suction tube into the bottom of the barrel, the tube is easily bent or the tube mouth directly contacts the bottom of the barrel, resulting in the dialysate suction tube mouth being unable to approach the bottom of the barrel or the suction mouth being blocked, so that this part of the dialysate cannot be sucked and configured by the dialyzer, resulting in waste of dialysate. Utility Model Content

[0004] The utility model discloses a dialysate barrel, which is intended to solve the technical problems that, in the process of inserting a dialysate suction tube into the dialysate barrel, the dialysate suction tube is easily bent or conflicts with the barrel bottom, the suction port cannot be close to the barrel bottom or the suction port is blocked, resulting in part of the dialysate concentrate cannot be configured and used, causing waste, and the aluminum foil is difficult to tear open and the opening is too large, causing the dialysate to be excessively contaminated by contact with the outside world.

[0005] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present utility model are as follows:

[0006] A dialysate barrel comprises a barrel body, the barrel body being detachably connected to a barrel cover, the barrel cover being provided with a guide sealing mechanism, the guide sealing mechanism comprising a guide tube, one end of the guide tube being in contact with the inner bottom surface of the barrel body, and the other end being sealably connected to the barrel cover, the end of the guide tube close to the inner bottom surface of the barrel body being a hollow conical structure, the side wall of the conical structure being provided with a plurality of liquid suction holes, the liquid suction holes being connected to the interior of the barrel body.

[0007] After adopting this technical solution, the dialysate suction tube can be vertically arranged in the dialysate bucket through the guide tube, and the bottom suction port of the dialysate suction tube contacts the conical structure at the end of the guide tube, thereby preventing the suction port from directly contacting the bottom inside the dialysate bucket, which would cause the suction port to be blocked and affect the configuration of the dialysate. In addition, the tip of the conical structure of the guide tube can easily open the aluminum film at the mouth of the dialysate bucket, and open a through hole on the aluminum film that is adapted to the size of the guide tube opening. By fixing the bucket cover on the barrel body, the contact between the dialysate bucket and the outside world can be reduced, and it will not be contaminated by other impurities such as dust in the air.

[0008] Among them, the barrel cover is provided with a groove connected with the barrel body, the barrel cover is provided with a sealing cover matching with the groove, a fixing plate is provided in the groove, the fixing plate is fixedly connected with the guide tube, and a straw inlet connected with the guide tube is also provided on the fixing plate, the inner side wall of the straw inlet is fixedly connected with a sealing ring, and the inner side wall of the sealing ring is connected with a one-way membrane.

[0009] After adopting this technical solution, the size of the sealing ring can limit the size of the one-way membrane, so that the through hole that can be opened by the one-way membrane and the size of the dialysate suction tube have an interference fit, and then the dialysate suction tube is fixed in the through hole pushed open by the one-way membrane through the friction force between the one-way membrane and the dialysate tube, making it difficult to shake, so that the dialysate suction port located at the bottom of the dialysate barrel can evenly suck the dialysate concentrate into the dialyzer.

[0010] The sealing cover is hinged to the outer side wall of the barrel cover, and the inner side surface of the sealing cover is provided with a sealing protrusion which cooperates with the straw inlet.

[0011] After adopting this technical solution, the sealing protrusion on the inner side of the sealing cover cooperates with the straw inlet, so as to ensure the sealing inside the dialysate barrel when the dialysate barrel is not in use. At the same time, when the dialysate straw is subsequently inserted into the dialysate barrel, the cooperation between the dialysate straw and the one-way membrane reduces the contact between the dialysate concentrate and the outside world.

[0012] Among them, the outer wall of the barrel mouth is provided with an external thread, and the inner wall of the groove is also provided with an internal thread matching the external thread.

[0013] After adopting this technical solution, the barrel cover can be fixed to the bottle body by screwing together the internal and external threads.

[0014] Wherein, a barrel cover or an original cover is detachably connected to the barrel mouth of the barrel body.

[0015] After adopting this technical solution, the dialysis concentrate can be placed and sucked out into the cavity inside the barrel body through the barrel mouth, and the barrel cover can be installed on the barrel body.

[0016] Wherein, a handle is fixedly connected to the barrel body.

[0017] After adopting this technical solution, the dialysate barrel can be carried by the handle.

[0018] Wherein, the side wall of the conical structure is also provided with a plurality of opening grooves.

[0019] After adopting this technical solution, the groove tip formed by the open groove can quickly poke open the aluminum film located at the mouth of the dialysate bucket.

[0020] Among them, the end of the guide tube away from the inner bottom surface of the barrel body is a hollow cylindrical structure, and the side wall of the cylindrical structure is provided with several suction holes with the same structure as the side wall of the conical structure, and the suction holes are all connected to the inside of the barrel body.

[0021] After adopting this technical solution, the dialysate suction tube can quickly absorb liquid through the liquid suction ports on the columnar structure and the conical structure.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0023] (1) A guide tube with a conical bottom, a columnar middle and end, and a plurality of suction holes on the side wall is used to guide the dialysate suction tube entering the dialysate bucket, so that the dialysate suction tube can always remain vertical and the suction port is arranged close to the bottom of the dialysate bucket, thereby avoiding insufficient suction caused by the dialysate suction tube bending or directly contacting the bottom of the dialysate bucket, thereby affecting the configuration of the dialysate.

[0024] (2) A fixing plate is provided on the bottle cap, a straw inlet is provided on the fixing plate, a sealing ring is fixedly connected to the straw inlet, and the sealing ring is connected to a one-way membrane to perform interference fit on the dialysate straw located at the barrel mouth, thereby fixing the dialysate straw, reducing the shaking of the dialysate straw, and reducing the contact between the inside of the dialysate barrel and the outside world, thereby avoiding contamination caused by an overly large barrel mouth or a barrel lid simply covering the barrel mouth.

[0025] (3) A detachable barrel body is used in combination with a barrel cover, so that any dialysate barrel whose barrel mouth can be matched with the barrel cover can use the bottle cover to seal the dialysate barrel. At the same time, one end of the guide tube is set to a conical structure, and an opening groove is set on the side of the conical structure to facilitate poking open the aluminum film at the mouth of the dialysate bottle, and the size of the opening of the aluminum film is matched with the size of the guide tube, thereby reducing the gap between the guide tube and the aluminum film, thereby reducing contamination.
