Embodiment 1

[0025] This embodiment provides a one-time use of red blood cell bone marrow collection bag, such as figure 1 As shown, including screw joint one 2, screw joint two 7, collection catheter one 3, collection catheter two 9, switch device one 4, switch device two 6, blood transfusion set socket one 5, blood transfusion set socket two 17, anticoagulant bone marrow preservation Bag 11, red blood cell collection bag 19, transfer catheter 15, and switch device 3 16; one end of the collection catheter 1 3 and the collection catheter 2 9 are respectively connected to one end of the anticoagulant bone marrow storage bag 11, and the other ends are respectively provided with a spiral Joint one 2 and screw joint two 7; the switch device one 4 and switch device two 6 are respectively arranged on the collection catheter one 3 and the collection catheter two 9; the blood transfusion set socket one 5 is connected to the anticoagulant bone marrow preservation bag 11. The other end of the antico...

Embodiment 2

[0039] This embodiment provides a method for using the disposable red blood cell-removed bone marrow collection bag described in Embodiment 1, which includes the following steps:

[0040] Directly connect with the syringe for aspirating bone marrow through the screw joint one 2, turn on the switch device one 4; directly inject the bone marrow blood via the collection catheter one 3 into the anticoagulant bone marrow storage bag 11 through the syringe; switch device two 6 and switch device three 16 keep closed;

[0041]This can prevent the operating doctor from putting the syringe on the needle again and piercing the catheter, so as to avoid injuring the operating doctor's fingers or bringing in pollutants; 9 opening and closing, to avoid backflow of bone marrow blood. The switch device 3 16 is used to adjust the opening and closing of the transfer catheter 15 to prevent the bone marrow blood from directly entering the red blood cell collection bag 19 without separation.

Abstract

The invention discloses a disposable-use red blood cell bone marrow collecting bag and method. The collecting bag comprises a spiral contact I, a spiral contact II, a transfusion apparatus socket I, atransfusion apparatus socket II, an anti-freezing bone marrow preserving bag, a red blood cell collecting bag, a transfer duct and a switching device III, wherein the spiral contact I and the spiralcontact II respectively communicate with one end of the anti-freezing bone marrow preserving bag; the transfusion apparatus socket I communicates with the anti-freezing bone marrow preserving bag; theother end of the anti-freezing bone marrow preserving bag communicates with one end of the transfer duct, and the other end of the transfer duct communicates with one end of the red blood cell collecting bag; the transfusion apparatus socket II communicates with the red blood cell collecting bag; and the switching device III is arranged on the transfer duct. The collecting bag provided by the invention is reasonable in structure, convenient to operate and low in cost, clinical bone marrow collection is convenient to realize, and technical requirements for removing red blood cells in bone marrow blood can also be met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable red blood cell-removed bone marrow collection bag and a method thereof. Background technique [0002] At present, in the clinical operation of bone marrow transplantation, a disposable blood collection bag is used to collect bone marrow. The existing disposable blood collection bag generally includes a closed blood collection needle, a catheter, and an anticoagulated whole blood bag. Bone marrow is a connective tissue composed of a large number of hematopoietic stem cells located in the bone marrow cavity. It can only be collected by a clinician by inserting a bone marrow puncture needle into the bone marrow cavity and sucking it with a syringe. The catheter of the disposable blood collection bag injects the bone marrow into the anticoagulated whole blood bag for preservation. However, it is easy to puncture the operator's fingers or bring in pollutants duri...
