Example Embodiment
[0028] The present invention will be described in detail below with reference to the drawings and embodiments.
[0029] Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.
[0030] Referring to Figures 1, 2 and 3, a first preferred embodiment of the medical appliance with retraction force of the present invention includes: a tube 1, a coupling member 2, an actuating member 3, a needle set 4, and One elastic element 5.
[0031] The tube 1 has a tube wall 12 surrounding an axis and defining a lumen 11, a guide groove 13, a first rib 14, a second rib 15, a supporting portion 16, and a sliding seat 17 , And an end cap 18. The pipe wall 12 has an inlet end 121 and an outlet end 122 opposite to each other, a large pipe diameter section 123 and a small pipe diameter section 124 respectively adjacent to the inlet end 121 and the outlet end 122, formed on the large and small A shoul...

This invention discloses a medical appliance with reverse draft force, which comprises a pipe element, a combined part which can be held in the pipe element by displacement, a syringe body which is connected with the combined part, an elastic element which is arranged between the pipe element and the combined part, and a start element, wherein, the pipe element is provided with a guide slot with the formation of a jamming face and a sliding fit; the combined part is provided with a flange bolt which passes through the guide slot and is blocked by the jamming face; the start element is slide fitted with the sliding fit and provided with a poking control part which presses against the flange bolt of the combined part, and can interlock with the poking control part due to outside force to poke the flange bolt of the combined part to match together with the guide slot so as to ensure that the combined part displaces with the flange bolt along the guide slot under the force of the elastic element and drives the syringe body to displace even to be hidden inside the pipe element. Therefore, the application and the operation of the medical appliance for clinical care is relatively convenient and safe.
Description
technical field [0001] The invention relates to a medical appliance, in particular to a medical appliance which can hide a needle body and has a retracting force. Background technique [0002] Generally, in clinical medicine, after intramuscular injection, intravascular infusion drip injection, blood sample extraction, or the above-mentioned infusion drip injection and blood extraction operations are performed simultaneously, sharp needles must be properly handled to avoid needles stabbing the human body. , or even be infected by the blood with the source of infection remaining on the needle body. Although the previous injection tubing includes a needle cover covering the needle body, it is often lost or dropped during the operation on the hospital bed, and because the hole diameter of the needle cover for the needle body to pass through is quite limited, the user has to complete the injection When putting away the needle (device) at the end, the action of returning the tro...
