Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
The basic principle of peritoneal dialysis is that peritoneal membrane is used as dialysis membrane, dialysis solution and blood which are infused into peritoneal cavity are separated, the peritoneal membrane has semi-permeable membrane property, and has the characteristics of large area, abundant capillaries and the like, medicine adding is needed to be carried out on the A bag or sample extracting is needed to be carried out on the B bag in the peritoneal dialysis operation (as shown in figure 4), medicine adding is carried out on the A bag through the butt joint C of an injection needle, medicine pushing is carried out on the B bag, the sample extracting is carried out by directly puncturing the surface of the bag through the needle, and the occupational exposure phenomenon is easy to occur to medical staff due to the risks of the two, and referring to figure 1, the scheme designs an abdomen penetration needle sleeve, wherein the main body comprises an injection sleeve 1, the injection sleeve 1 is a cylindrical object, and two ends penetrate through and is used for connecting the operation between a target object and a medical operation needle;
referring to fig. 3, an injection plug 2 is disposed in the injection sleeve 1, the injection plug 2 is movable in the injection sleeve 1, a plurality of pinholes 3 are formed in the end face of the injection plug 2 in a penetrating manner, the pinholes 3 can be irregularly arranged, the diameter of the pinholes 3 is slightly smaller than that of a standard injection needle, the needle is required to be inserted into the pinholes 3 before use, care is required during insertion, and the diameters of the pinholes 3 are slightly smaller than that of the standard injection needle because the injection plug 2 is made of rubber, so that the injection plug 2 is required to be slowly inserted into the pinholes 3, so that the operation difficulty is reduced, the design of the injection plug 2 is as short as possible, and the operation distance is reduced.
The needle is inserted and then can be effectively wrapped and fixed by the telescopic deformation of the plurality of needle holes 3, the injection needle can be moved after the injection plug 2 moves, the upper end of the injection sleeve 1 is provided with the strip-shaped opening 4, the size of the opening 4 is not lower than half of the length of the injection sleeve 1 so as to have enough sliding distance, the movable clamp 5 is arranged in the opening 4, the movable clamp 5 penetrates through the opening 4 and is fixedly connected with the injection plug 2, the movable clamp 5 is movably clamped with the opening 4, medical staff can drive the injection plug 2 to move through the movable clamp 5, and the butt joint of a medicine adding port at the C position in fig. 4 and the sample sampling operation at the B position can be completed.
But the mode that directly punctures is adopted when taking a sample to the department of B, consequently there is the danger of occupational exposure still, so referring to figure 2, injection tube cover 1's terminal port department fixedly connected with many spring leaves 6, many spring leaves 6 evenly set up on injection tube cover 1's inner wall, and be close to its edge setting, spring leaf 6 is the convex bulge form in middle part, injection tube cover 1's terminal port department inserts and is equipped with cotton piece 7, cotton piece 7 is cylindric, the diameter is the same with injection tube cover 1 port diameter, before using cotton piece 7 to insert to injection tube cover 1's terminal, utilize many spring leaves 6 to carry out the block, cotton piece 7 is porous structure, needle point department is through comparatively easy, when there is the condition of leaking in B department, cotton piece 7 can be quick absorption, prevent to leak, make the hidden danger that medical personnel can very big reduction occupational exposure, the effectual security that has improved the operation, simultaneously also improved the convenience, in addition when the medicine mouth of C in the butt joint figure 4, also can increase the effect with the spring piece of adding mouth through 6.
