Abstract

The present invention relates to a tubing of a safety intravascular cannula, comprising a barrel, a needle holder, a resilient member, a tubing holder and a plug. The needle holder forms a plurality of notches engageable with resilient clips projecting from the barrel to make the needle of the needle holder extending into the tubing of the tubing holder. When the tubing holder and the barrel are separated, the resilient clips of the barrel disengage from the notches of the needle holder to allow the resilient force of the resilient member to automatically withdraw the needle back into the barrel. As such, damage by the needle due to inadvertent handling by a user can thus be avoided.

Automatically retrieve the needle in the safe venous indwelling catheter in the syringe. ° [Prior art] Catheters are used to inject medical fluids into the patient's blood. Medical fluids, such as raw saline or therapeutic agents, generally include a syringe, a catheter, and a needle. The needle is inserted into the catheter during use. In the catheter, the medical staff uses the needle: the catheter is inserted into the patient's blood vessel, and once it is inserted into the guide, the guide needle and the syringe can be detached, and the catheter is left on the patient. When the people need to input the medicine liquid, the needle end of the drip bottle can be directly inserted into the tube C, which can prevent the patient from entering the medicine liquid at different times, and it is not difficult for the patient to find the blood vessel input place because of multiple needles. Needed solution. However, the conventional catheter is exposed to the needle outside the needle from the head, so when the needle & Tian Yishi's treatment of the needle was too dangerous to handle the needle test, but at this time, the + is required because of the need for the patient to simultaneously inject the lotion required by the patient into the patient's body and handle the needle of ^ ^ AA ^ Therefore, the needles that are bare in this way are easy to cause personnel, knowledge, or must be covered by the needle cover immediately after the needles are pulled out. The human shell must be two members ’within a short period of time, and the medicinal solution must be connected to the catheter, so there may be a needle injury due to the Shang needle. In addition, those who deal with waste may also be dangerous because of the use of daggers and careful handling. Therefore, how to avoid the above-mentioned 1237575 deficiency is a need for improvement of the relevant manufacturers. [Summary of the Invention] The lack of improvement in conventional usage is accepted. The present invention provides an automatic Return the needle to the safety tube in the ten cylinder to avoid injuring the medical staff. In order to achieve the above-mentioned purpose, the present invention / it S4z does not provide a safety vein indwelling needle B, which includes a syringe, an oblique culvert with a needle seat, an elastomer, a catheter seat, and A plug. The syringe has a catheter seat with the surname U β 00 combined with a V port and an open end. The catheter seat ... is provided with a perforation and a plurality of elastic pieces protruding outward; the needle seat is assembled in the syringe and The joint end of the jigs, ten members ~ β end and a base port ^, the base of the needle base is combined with the needle rattan wide production ^ 埂 5 and there is a needle base base, axial < + + 'In addition, the center of the needle seat is provided with a passageway in the glaze, and the TBM needle is inserted, and there is a protrusion protruding from the combined end of the needle in the 11 ^^; the recess has a number of ring-shaped grooves. The elastic system Assembled in a syringe and equipped with a nightmare of the syringe set, π α has a needle mount assembly end and "the elastomer is sleeved outside the needle mount m and the mounting end is against the oblique ridge of the needle mount. The needle base group is on the base of the needle base, and the combined end of the tube seat of the tube is the same, and the mounting end is against the needle. The tube seat is assembled and fixed to the guide of the syringe. ΌA end, which is connected to the inner end and extends from the 刖 end to form a channel connecting from the chamber, and the duct is widened in the chamber. The distance between the heart and the perforation is the length of the perforation, and the elastic piece of the syringe is not supported by the needle against the inner wall of the 1235775 of the container; the plug body is assembled at the open end of the syringe. Intravenous indwelling needle catheter into a + sleeve cover outside the catheter seat and set on the outer edge of the barrel. ^ Includes-needle cover 'in the safe intravenous indwelling needle catheter described in this needle, clip-shaped. Μ elastic sheet is a pair of It shows the diameter of the passage of the safety needle of the safety vein indwelling needle guide. The mutual k is smaller than the medium 'The elastomer is a spring. The medium' The plug is a breathable plug. The needle can be automatically recovered in the syringe because Inadvertent handling caused by the medical waste disposal staff or the safe venous indwelling needle catheter described by the surrounding people. Therefore, the present invention can avoid personnel when the needle is pulled out of the catheter after use. [Implementation] As shown in the first and second figures, the safety venous indwelling needle guide of the present invention; wide syringe (30), -needle s (10) , -Elastomer (0) and a plug), a Tube base (40), a needle sleeve ((60)). One needle is the same as (30), which has-catheter seat coupling end (3 2) and-(while (34), the guide seat coupling end (32) A perforation 6 is provided therethrough, and a plurality of elastic pieces (3 8) are preferably protruding outward. Preferably, the elastic pieces (3 8) are a pair and are clip-shaped. 1237575 The needle base (1 ο) is assembled on the joint end ( 2 2) and a 0), and has a (") base joint end c] 4 t end (14), the needle base"), and the radius of the needle base base needle base (0), and the other Needle seat (value is greater than the needle seat (1 17) Shen ~ lightly set to the right office, Dad,
