The invention relates to an improved venous indwelling needle protection net sleeve device which comprises a net sleeve body used for sleeving a limb of a patient, and is characterized in that the net sleeve body comprises a single-layer net sleeve and a reverse folding type double-layer net sleeve integrally connected to the lower end of the single-layer net sleeve, and a pipe penetrating opening is formed in the connecting position of the single-layer net sleeve and the reverse folding type double-layer net sleeve; an extension tube on the venous indwelling needle can penetrate out of the net sleeve body through the tube penetrating opening and is bent upwards, and U-shaped fixation is maintained. A heparin cap protection sleeve is arranged at the upper end of the outer side face of the single-layer net sleeve, the upper side edge, the left side edge and the right side edge of the heparin cap protection sleeve are closed, an opening is reserved in the lower side edge, and a heparin cap at the tail end of the extension tube can be arranged in the heparin cap protection sleeve through the opening in the lower side edge of the heparin cap protection sleeve. The extension tube can penetrate out of the net sleeve body from the tube penetrating opening and is bent upwards to be U-shaped, and the U-shaped bent part and the thumb clamp are placed in the reverse folding type double-layer net sleeve, are fixed properly and cannot make direct contact with the skin, friction is reduced, and the comfort of a patient is improved.
Description
technical field [0001] The invention relates to an indwelling needle protection device, in particular to an improved venous indwelling needle protection net cover device, which belongs to the technical field of medical equipment design. Background technique [0002] Intravenous indwelling needle is a better method for clinical infusion. On the one hand, it can reduce the pain caused by repeated venipuncture and the fear of injections in children. On the other hand, it can also reduce the workload of clinical nurses. It is also suitable for long-term infusion of adults. Clinically, when the intravenous indwelling needle is inserted into the child's body, the child may move the intravenous indwelling needle from time to time. Pulling the venous indwelling needle, these situations may cause the venous indwelling needle to fall off or shift, causing secondary harm to the child. [0003] In order to avoid the above-mentioned problems, some medical units have designed heparin ca...
