Centralized collection device for marrow fluid samples of blood disease

Abstract

The invention discloses a centralized collection device for the marrow fluid sample of a blood disease, and belongs to the technical field of medical instruments. The invention discloses a centralized collection device for the marrow fluid sample of a blood disease. The centralized collection device comprises a positioning disc, wherein a plurality of through holes are arranged on the surface of the positioning disc; a cylinder is rotationally connected to the middle of a limiting block; a limiting sliding groove rod is arranged at the lower end of the inner side of the limiting block; a recoverer body is inserted into the middle of a moving block; and an iodine cotton block is arranged on the lower side of the moving block. Due to tight cooperation among structures, when the centralized collection device is used, after the positioning disc is fixed, a medical worker observes a camera for carrying out an operation, so that the moving block can rotate and move inwards and outwards, coordinate positioning is conducted on a to-be-punctured part, after disinfection is conducted through the iodine cotton block, the recoverer body is inserted into the moving block for carrying out puncture sampling, accurate positioning can be achieved, meanwhile, the situation that the medical worker holds with the hand and shakes during puncture and extraction through holding with the hand is avoided, the comfort level of a patient is improved, and puncture and extraction effects and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a centralized collection device for blood disease bone marrow fluid samples. Background technique [0002] Bone marrow aspiration is a common diagnostic technique using bone marrow fluid. It is suitable for the diagnosis, differential diagnosis and treatment follow-up of various blood diseases, unexplained increase or decrease in the number of red blood cells, white blood cells, and platelets, abnormal morphology, and unexplained fever. Diagnosis and differential diagnosis can be used for bone marrow culture, bone marrow smear to find parasites, etc. There is no specific device to recover intervertebral bone marrow clinically, and the operation of bone marrow recovery is very troublesome. The prior art publication No. CN112914689A provides an intervertebral bone marrow recovery device. The device presses the first air bag of the negative pressure generating assem...

Problems solved by technology

The prior art publication No. CN112914689A provides an intervertebral bone marrow recovery device. The device presses the first air bag of the negative pressure generating assembly through the set negative pressure generating assembly and the recovery bottle assembly, so that the airflow generated by the first air bag Enter the external drainage tube from the fixed tube and enter the patient's lumbar spine from the puncture needle, so that the bone marrow in the lumbar spine leaks slowly. After observing the bone marrow enters the external drainage tube from the puncture needle, release the first air bag to allow the airflow to flow back. The airflow pushes the bone marrow to infiltrate into the fixed tube, and flows into the inside of the bottle along the side wall of the fixed tube through the external inclined tube on one side of the fixed tube to realize recovery. Although the device has many beneficial effects, the following problems still exist: the device Hand-held puncture extraction after sticking and fixing, there is a situation where medical staff shake hands, causing discomfort or pain to patients, affecting puncture extraction;

[0003] In addition, among the existing anti-shake solutions, for example, CN110448341A is a bone marrow puncture auxiliary device for hematology department. This invention can provide support and fixation for the syringe, and can prevent the medical staff from holding the syringe for a long time, thereby avoiding hand fatigue of the medical staff. , which reduces the workload of medical staff and can avoid the shaking of the injection needle, but it only provides support for the syringe, and the syringe needs to be pressed manually, which cannot guarantee the accuracy of the puncture

[0004] In the existing anti-shake solution, CN213758477U is used for the bone marrow puncture auxiliary device in the department of hematology. During the extraction of marrow fluid, the bolts need to be manually screwed and the auxiliary device needs a U-shaped support platform at the bottom, so it is difficult for the ground and occupies a lot of space. Space is required
