Description

Technical Field

[0001] The utility model belongs to the technical field of blood collection, in particular to a blood collection cooling bag. Background Art

[0002] Platelet-rich fibrin (PRF) is a platelet-rich biomaterial that is different from traditional platelet-rich plasma (PRP) technology. PRF can promote bone formation, especially improve the healing rate of bone transplant wounds. When PRF is used in tooth repair, the patient's blood is collected and cooled and centrifuged to obtain S-PRF serum and A-PRF jelly. The S-PRF serum, bone powder and part of the A-PRF jelly are mixed to prepare viscous bone, and the remaining part of the A-PRF jelly is flattened to prepare a solid plasma matrix membrane. The viscous bone and the solid plasma matrix membrane are used together for tooth repair. At present, when collecting blood from patients, the blood is collected into a test tube and then placed in a 4℃ refrigerator for refrigeration. The purpose of cooling the blood immediately cannot be achieved, and the optimal cooling effect of cooling immediately after blood collection cannot be achieved, which affects the cooling and centrifugation effect of S-PRF serum and A-PRF jelly. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a blood sampling and cooling bag which can timely cool down the blood when blood is collected from a patient.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a blood collection cooling bag, comprising a bag body, a first Velcro strip, a thermal insulation cloth, a semicircular guide tube, a first cooling bag, a second cooling bag, a traction rope and a rubber limit block, two first Velcro strips are fixedly installed on the upper end of the bag body, the first cooling bag and the second cooling bag are alternately and continuously fixed on the bag body, the semicircular guide tube is fixedly installed on the bag body, the semicircular guide tube is located at the left and right ends of the first cooling bag, the height dimension of the first cooling bag is 1.5-3 times the height dimension of the second cooling bag, the rear ends of the two traction ropes are fixedly installed on the rear end of the bag body, two rubber limit blocks are fixedly installed on the front end of the bag body, the front end of the traction rope can be clamped and limited in the slot of the rubber limit block, and the thermal insulation cloth is fixedly matched with the bag body with a second Velcro strip and a third Velcro strip.

[0005] Preferably, a U-shaped groove is provided at the front end of the bag body, and two rubber limiting blocks are fixedly installed in the U-shaped groove at the front end of the bag body.

[0006] Preferably, a pull ring is fixedly installed on the outer end of the traction rope.

[0007] Compared with the prior art, the advantages of the utility model are: by setting the thickness dimension of the second cooling pack to be thinner than the thickness dimension of the first cooling pack, the blood collection tube can be wrapped between the first cooling pack and the second cooling pack by tightening the traction rope to achieve a better cooling effect, and by setting a thermal insulation cloth, the arm of the person having blood drawn can be prevented from directly contacting the first cooling pack, thereby improving the comfort during blood collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The utility model is further described below in conjunction with the accompanying drawings.

[0009] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0010] The utility model is described in detail below in conjunction with specific implementation methods:

[0011] like Figure 1 The blood collection cooling bag shown includes a bag body 1, a first Velcro strip 2, a thermal insulation cloth 3, a semicircular guide tube 41, a first cooling bag 5, a second cooling bag 51, a traction rope 6 and a rubber limiting block 62. The two first Velcro strips 2 are fixedly installed on the upper end of the bag body 1. The first cooling bag 5 and the second cooling bag 51 are alternately and continuously fixed on the bag body 1. The semicircular guide tube 41 is fixedly installed on the bag body 1. The semicircular guide tube 41 is located at the left and right ends of the first cooling bag 5. The height of the first cooling bag 5 is 2.3 times the height of the second cooling bag 51. The rear ends of the two traction ropes 6 are fixedly installed at the rear end of the bag body 1. Two rubber limiting blocks 62 are fixedly installed at the front end of the bag body 1. The front end of the traction rope 6 can be clamped and limited in the groove of the rubber limiting block 62. The thermal insulation cloth 3 is fixedly matched with the bag body 1 with a second Velcro strip 31 and a third Velcro strip 32.

[0012] The front end of the bag body 1 is provided with a U-shaped groove 10, and two rubber limit blocks 62 are fixedly installed in the U-shaped groove 10 at the front end of the bag body 1. The rubber limit blocks 62 can be installed in the left and right directions in the U-shaped groove 10 to avoid the problem of the rubber limit blocks 62 being uncomfortable when installed vertically.

[0013] A pull ring 61 is fixedly installed on the outer end of the traction rope 6 so that the traction rope 6 can be pulled through the pull ring 61 .

[0014] After the blood collection and cooling pack is taken out from the cold storage room, the blood collection tube 4 is placed in the second cooling pack 51 between the two first cooling packs 5. The blood collection tube 4 is also buckled and installed in the slot of the semicircular guide tube 41. The semicircular guide tube 41 can prevent the blood collection tube 4 from being blocked due to excessive bending angle. Since the thickness dimension at the second cooling pack 51 is thinner than the thickness dimension at the first cooling pack 5, when the traction rope 6 is pulled, the second cooling pack 51 is bent, and the blood collection tube 4 is wrapped and cooled by the first cooling pack 5 and the second cooling pack 51. The traction rope 6 is snap-fitted and installed in the slot of the rubber limiting block 62 for limit fixing, covering the insulation cloth 3, and the second Velcro strip 31 and the third Velcro strip 32 are bonded and fixed, which can prevent the arm of the person whose blood is drawn from direct contact with the first cooling pack 5, thereby improving the comfort during use. The blood collection and cooling pack can be tied to the arm of the person whose blood is drawn through the first Velcro strip 2.
