Description

Technical Field

[0001] The utility model relates to the technical field of dialysis experimental tools, and more specifically to a dialysis bag clamp. Background Art

[0002] In the process of biological or chemical experiments, dialysis is a commonly used experimental operation. It can be completed by using a special semi-permeable membrane. The biological molecules with large molecular weight are retained in the bag, while salt and small molecules continue to diffuse and dialyze outside the bag until the concentration inside and outside the bag reaches equilibrium. The sample solution retained in the dialysis bag and not dialyzed is the retained solution, and the solution outside the bag becomes the dialysate.

[0003] However, in current actual operations, during the sealing process of the dialysis bag, a sealing clamp or a tightening device is used to seal the upper end of the dialysis bag. This sealing method is usually not able to seal completely, resulting in leakage of the contents. When using a sealing clamp, when clamping a thicker dialysis bag, cracking is prone to occur. When clamping a thinner dialysis bag, the sealing clamp is prone to slipping, resulting in leakage.

[0004] Therefore, providing a dialysis bag clamp that is tight and completely sealed is an issue that needs to be urgently addressed by those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a dialysis bag clamp, which can not only fasten the dialysis bag opening, but also prevent liquid leakage.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dialysis bag clamp comprises a first main body clamp, a second main body clamp, a first clamping portion, a second clamping portion and a third clamping portion, wherein the first main body clamp and the second main body clamp are softly connected via a connecting portion; the first clamping portion and the second clamping portion are both arranged at an extended end portion of the first main body clamp, and a space adapted to the third clamping portion is provided between the first clamping portion and the second clamping portion; the third clamping portion is rotatably connected to the extended end portion of the second main body clamp.

[0008] By adopting the above scheme, the beneficial effects of the utility model are:

[0009] The first clamping part, the second clamping part and the third clamping part cooperate with each other to achieve the fastening of the dialysis bag clamp and prevent the dialysis bag from leaking.

[0010] Furthermore, the third clamping portion is rotatably connected to the extended end portion of the second main body clamp via a rotating connection structure, so that the third clamping portion rotates along a plane perpendicular to the extension direction of the second main body clamp.

[0011] Furthermore, the extended end of the third clamping portion has a clamping groove, and the second clamping portion is provided with a protrusion corresponding to the position of the clamping groove. When the first main body clamp and the second main body clamp are closed, the two clamping surfaces of the extended end of the third clamping portion are embedded between the first clamping portion and the second clamping portion, and the protrusion is embedded in the clamping groove.

[0012] Furthermore, the first main body clamp is provided with a first fastening portion, and the second main body clamp is provided with a second fastening portion corresponding to the position of the first fastening portion. When the first main body clamp and the second main body clamp are closed, the first fastening portion is embedded in the second fastening portion.

[0013] Furthermore, the first fastening portion is a fastening plate, and the second fastening portion is a fastening groove.

[0014] Furthermore, the extended end of the second clamping portion is provided with an easy-open portion which forms an angle with the main body thereof. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , 2As shown, the embodiment of the utility model discloses a dialysis bag clamp, including a first main body clamp 1, a second main body clamp 2, a first clamping part 3, a second clamping part 4 and a third clamping part 5, wherein the first main body clamp 1 and the second main body clamp 2 are softly connected by a connecting part 6; the first clamping part 3 and the second clamping part 4 are both arranged at the extended end of the first main body clamp 1, and there is a space between the first clamping part 3 and the second clamping part 4 adapted to the third clamping part 5; the third clamping part 5 is rotatably connected to the extended end of the second main body clamp 2, and when the first main body clamp 1 and the second main body clamp 2 are mutually buckled, the third clamping part 5 is rotated and clamped between the first clamping part 3 and the second clamping part 4. The utility model realizes the fastening of the dialysis bag clamp and prevents the dialysis bag from leaking by cooperating with the first clamping part 3, the second clamping part 4 and the third clamping part 5.

[0020] Specifically, the third clamping part 5 is rotatably connected to the extended end of the second main body clamp 2 through the rotating connection structure 7, so that the third clamping part 5 rotates along the vertical plane of the extension direction of the second main body clamp 2. More specifically, during the dialysis process, the liquid to be dialyzed is placed in the dialysis bag, the opening of the dialysis bag is placed between the first main body clamp 1 and the second main body clamp 2, and the third clamping part 5 is first rotated clockwise or counterclockwise to form an angle with the vertical direction of the end of the second main body clamp 2 with the rotating connection structure 7 as the rotation fulcrum, and the first main body clamp 1 and the second main body clamp 2 are buckled, and then the third clamping part 5 is rotated so that it is clamped into the space formed between the first clamping part 3 and the second clamping part 4 to achieve buckling.

[0021] In order to further optimize the technical solution of the utility model, the extended end of the third clamping portion 5 has a clamping groove 51, and the second clamping portion 4 is provided with a protrusion 41 corresponding to the position of the clamping groove 51. When the first main body clamp 1 and the second main body clamp 2 are closed, the two clamping surfaces of the extended end of the third clamping portion 5 are embedded between the first clamping portion 3 and the second clamping portion 4, and the protrusion 41 is embedded in the clamping groove 51.

[0022] In order to further optimize the technical solution of the utility model, a first fastening portion 8 is provided on the first main body clamp 1. In this embodiment, the first fastening portion 8 is a fastening plate, and a second fastening portion 9 corresponding to the position of the first fastening portion 8 is provided on the second main body clamp 2. In this embodiment, the second fastening portion 9 is a fastening groove. When the first main body clamp 1 and the second main body clamp 2 are closed, the first fastening portion 8 is embedded in the second fastening portion 9. More specifically, during the dialysis bag dialysis process, the end of the dialysis bag containing the liquid is clamped and placed on the first fastening portion 8. When the second main body clamp 1 and the first main body clamp 2 are buckled, in order to further tighten the tightness between the dialysis bag and the clamp, the first fastening portion 8 and the second fastening portion 9 are mutually embedded and engaged, so that the end of the dialysis bag can be tightened. At the same time, when the dialysis bag port is tightened, the dialysis bag port will be deformed according to the buckling between the first fastening portion 8 and the second fastening portion 9, filling the gap between the two, thereby achieving the port sealing effect of the dialysis bag.

[0023] In order to further optimize the technical solution of the utility model, the extended end of the second clamping portion 4 is provided with an easy-opening portion 42 which is at an angle to its main body. When opening the dialysis bag clamp, the hand is placed on the easy-opening portion 42 and lifted in the direction opposite to the raised portion 41, so that the raised portion 41 is rotated out from the inside of the clamping slot 51, thereby realizing the opening operation and facilitating the application of force when opening.
