Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

As shown in fig. 1 and as 2, a needle protective sheath is kept somewhere to vein, including protective sheath body 1, protective sheath body 1 is the tubular structure, protective sheath body 1 includes inlayer 11 and cover and establishes outer 12 outside inlayer 11, inlayer 11 is the ventilative material of elasticity, the skin is waterproof material, and waterproof material can be transparent materials such as silica gel material or PVC or PS, the one end of skin 12 with the one end fixed connection of inlayer 11, the other end of skin 12 is the free end, skin 12 can be followed free end rolling to stiff end. Because one end of the outer layer 12 is movable, when the outer layer 12 is worn and can not contact water, the waterproof outer layer 12 can be wound from a free end to a fixed end, the inner layer 11 is sleeved at the position of the indwelling needle, and the inner layer 11 has better air permeability, so that the comfort is improved; when waterproof water is needed, the outer layer 12 can be put down to play a waterproof role, and the protective sleeve can simultaneously take waterproof and air permeability into consideration according to different use environments.

In order to prevent water from leaking into the protective sleeve body and realize waterproof sealing, a tightening structure 3 for contracting or opening the sleeve opening of the outer layer 12 is arranged at the sleeve opening of the movable end of the outer layer 12, and an annular water absorbing layer 4 is arranged on the inner wall of the fixed end of the outer layer 12, which is positioned on the inner layer 11. The water-absorbing layer 4 can be made of sponge or common cotton. In this embodiment, the tightening structure 3 includes a cavity 31, a tightening belt 32 and a pull ring 33, the cavity 31 is annularly disposed at the opening of the outer layer 12, the cavity 31 has a pair of openings oppositely disposed for the tightening belt 32 to pass through, the tightening belt 32 is disposed in the cavity 31, and two ends of the tightening belt 32 extend out of the openings of the cavity 31; the pull ring 33 is connected to the one end of tightening belt 32, the other end of tightening belt 32 passes through pull ring 33 and is connected with the outside of cavity 31 far away from one end of pull ring 33 through the magic subsides. Specifically, the magic subsides include magic tape hook face 34 and magic tape matte 35, magic tape hook face 34 is located on keeping away from the front of the tightening belt 32 of pull ring 33 one end, magic tape matte 35 is located on keeping away from the lateral wall of the cavity 31 of pull ring 33 one end, magic tape hook face 34 with magic tape matte 35 cooperatees and colludes even. When a patient washes one's face or washes one's hands at ordinary times, because water is difficult to flow into the protective sleeve body 2 from the looping, the magic tapes can be separated, so that the looping is loosened, the tightening belt 32 is difficult to tighten the arms, and the comfort level is increased; when the patient needs to have a bath and wash hair etc. operation, in order to prevent that water from flowing into protective sheath body 1 from the looping, make tightening belt 32 pass pull ring 33, then to the suitable tightness of pulling back again, utilize the magic on tightening belt 32 to paste hook face 34 and the magic on the cavity 31 and paste the hair side 35 and connect to tighten up outer 12 looping. The tightening process can be operated by one hand, and is simple and convenient.

In order to prevent the tightening strap 32 from inadvertently entering the cavity 31 at either end during pulling and not being easily removed, the diameter of the pull ring 33 is larger than the diameter of the opening of the cavity 31, and a pull ball 7 is fixed to the tightening strap 32 at the end remote from the pull ring 33, the diameter of the pull ball 7 being smaller than the diameter of the pull ring 33 and larger than the diameter of the opening of the cavity 31. Because the diameters of the pull rings 33 at the two ends and the pull balls 7 on the tightening belt 32 are larger than the diameter of the opening of the cavity 31, the end of the tightening belt 32 cannot enter the cavity 31 to affect use even if one end is pulled by carelessly and the force is too large.

In order to prevent to lead to rolling up the skin and drop because of operations such as patient's motion or dressing, the outside of the stiff end of outer 12 is equipped with prevents structure 5 that scatters, prevent structure 5 that scatters including locating fixed band 51, couple 52 and link 53, the upper end and the outer 12 fixed connection of fixed band 51, couple 52 is connected to the lower extreme of fixed band 51, link 53 is located on the outer 12 inner wall and be close to outer 12 stiff end one side, couple 52 with link 53 colludes even.

The inner layer 11 is provided with an observation window 6, the periphery of the observation window 6 is sewn and connected with the inner layer 11, and the observation window 6 is made of transparent silica gel. The observation window 6 facilitates observation of the state of the indwelling needle.

The length of the indwelling needle protective sleeve body 1 is 15-20cm, when in use, a hand with an indwelling needle only needs to penetrate through the protective sleeve body 1, so that the inner layer 11 is tightly attached to the indwelling needle part, the inner layer 11 has elasticity, is suitable for the limb sizes of different patients and can be used repeatedly, the inner layer 11 is soft and has good air permeability, the wearing is more comfortable, and the indwelling needle is tightly attached to the indwelling needle, so that the indwelling needle can be prevented from shifting or falling off; according to the environment of use, can select to put down the waterproof material layer of skin 12 and roll up, when waterproof skin put down, the patient can wash one's face and rinse one's mouth, wash one's hands etc. and move in order to prevent to have a bath, wash one's hair etc. when moving, water flows into protective sheath body 1 from the cuff, still can tighten up the cuff through the tightening structure 3 of cuff department. When the waterproof outer layer 12 is rolled up, the hook 52 on the fixing band 51 is hooked with the hanging ring 53, so that the rolled outer layer 12 is prevented from scattering. The utility model discloses a protective sheath body has inlayer 11 and outer 12 to constitute, establishes the waterproof outer 12 that has a free end outside inlayer 11 through the ventilative inlayer 11 of elasticity and cover, can be according to the environment of use, with outer rolling or put down for keep somewhere needle protective sheath and compromise waterproof and gas permeability simultaneously in the use, improve the travelling comfort of using.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
