Abstract
The utility model relates to a marrow collecting filtering device which comprises a sleeve and filtering screens arranged in the sleeve. The upper end portion of the sleeve is provided with outer threads, a liquid outlet is formed in the lower end portion of the sleeve, and a step is arranged on the lower portion of the inner wall of the sleeve. The marrow collecting filtering device is characterized in that an annular locking cover is connected with the outer threads arranged on the upper end portion of the sleeve in a matched mode; the outer side of the lower portion of a liquid inlet component is in transition fit with the upper end portion of the inner wall of the sleeve, the upper portion of the liquid inlet component penetrates through the annular locking cover, and the lower portion of the liquid inlet component is tightly attached to the annular locking cover; the filtering screens are arranged in the sleeve from top to bottom, the filtering screen arranged at the lowest layer tightly abuts against the step of the lower portion of the inner wall of the sleeve, a spacer sleeve is arranged between every two adjacent filtering screens, and a pressing sleeve is arranged between the filtering screen arranged on the uppermost layer and the lower surface of the liquid inlet component. According to the marrow collecting filtering device, collected marrow can be rapidly filtered under the dense condition, small particles in the marrow can be removed, occurrence of the phenomenon of blocking is reduced, and pollution can be effectively avoided.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of bone marrow collection defecator.
Background technology
The treatment leukemia needs to do hematopoietic stem cell transplantation sometimes.Gathering bone marrow is the basic technology of hematopoietic stem cell transplantation, yet, contain a large amount of bone marrow small particles formed by fat drop, hemopoietic island cell mass, macrophage and fibrocyte in the bone marrow gathered, if do not filtered, directly input patient body and easily cause the complication such as thromboembolism after interior.Therefore, must in the process that gathers bone marrow, filter out described small particle.Marrow filter tool commonly used has small bore needle, drainage screen, transfusion filtration film etc., but Shortcomings all.Adopt No. 9 and twice filtration of No. 12 small bore needle, not only easily stop up pin hole, and pressure increases while filtering, the cell damage that is squeezed, reduced cell and become activity, and complex operation.Adopt drainage screen, owing to being open filtration, easily pollute.Therefore, need the new bone marrow collection defecator of exploitation.
Summary of the invention
The purpose of this utility model is to provide a kind of bone marrow collection defecator, it not only can carry out fast filtering to the bone marrow gathered under close state, get rid of the small particle in bone marrow, reducing the phenomenon of stopping up occurs, can also effectively avoid polluting simultaneously, and can also be directly as transfusion set, can be timely by the timely infusion of bone marrow cell suspension after filtering to the receptor.
A kind of bone marrow collection defecator described in the utility model, comprise sleeve, be located at the sieves in sleeve, and the upper end of described sleeve is provided with external screw thread, bottom is provided with leakage fluid dram, and the inwall bottom of described sleeve is provided with step, it is characterized in that:
The external screw thread of one annular tightening cover and described sleeve upper end is connected;
The outside, bottom of one feed liquor member and the upper end interference fits of described sleeve lining, through described annular tightening cover, bottom and the locking of this annular cover tightly subsides on the top of described feed liquor member;
Be provided with from top to bottom a plurality of sieves in described sleeve, the step of a nethermost sieves and described sleeve lining bottom near, be provided with spacer sleeve between two adjacent sieves, between a uppermost sieves and described feed liquor member following, be provided with clamping sleeve.
Described a kind of bone marrow collection defecator, the top of its described feed liquor member is communicated with the bone marrow collection bag.
Described a kind of bone marrow collection defecator is provided with from top to bottom three sieves in described sleeve.
Described a kind of bone marrow collection defecator, be located at the described size of mesh equal and opposite in direction of stating a plurality of sieves in sleeve.
Described a kind of bone marrow collection defecator, the size of mesh that is located at a plurality of sieves in described sleeve reduces from top to bottom successively.
Compared to the prior art this utility model has the following advantages: due to sieves is arranged in a sleeve, guaranteed under close state, the bone marrow gathered to be filtered, not only avoided outside contamination, and assembled easy, quick; Owing to being provided with a plurality of sieves in sleeve, be conducive to get rid of the small particle in bone marrow, thereby reduced the phenomenon of stopping up, occur, make to filter and carried out fast.And can also can directly connect tube for transfusion and syringe needle directly as transfusion set, can be by the timely infusion of bone marrow cell suspension after filtering to the receptor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further described.
A kind of bone marrow collection defecator shown in Figure 1, comprise sleeve 1, be located at the sieves 2 in sleeve, and the upper end of described sleeve is provided with external screw thread, bottom is provided with leakage fluid dram 11, and the inwall bottom of described sleeve is provided with step 12, and its construction features is:
One annular tightening cover 3 is connected with the external screw thread of described sleeve 1 upper end;
The outside, bottom of one feed liquor member 4 and the upper end interference fits of described sleeve 1 inwall, through described annular tightening cover 3, bottom and the locking of this annular cover tightly subsides on the top of described feed liquor member;
Be provided with from top to bottom the size of mesh equal and opposite in direction of 2, three sieves 2 of three sieves in described sleeve 1; The step 12 of a nethermost sieves and described sleeve lining bottom near, be provided with spacer sleeve 13 between two adjacent sieves 2, be provided with clamping sleeve 14 between a uppermost sieves and described feed liquor member 4 following.
Referring to Fig. 2, during use, the top of the feed liquor member 4 of described a kind of bone marrow collection defecator is communicated with bone marrow collection bag 5, and leakage fluid dram 11 coordinates with rubber stopper 6, and the empty needle syringe needle gets final product through rubber stopper 6.
The size of mesh that is located at a plurality of sieves 2 in described sleeve 1 reduces from top to bottom successively, and the size of mesh of sieves is less than 200 microns, is greater than 130 microns.
