Embodiment Construction

[0009] Below in conjunction with accompanying drawing and embodiment the structure of the present invention will be further described:

[0010] Marks in the figure: 1. shell; 2. hollow seal; 2-1. upper positioning column; 2-2. upper reinforcing rib; 2-3. lower reinforcing rib; 2-4. lower positioning column.

[0011] In the figure, the needle-free positive pressure medication infusion connector of the present invention is composed of a housing 1 and a hollow seal 2. There is a through hole in the housing 1, and the through hole is a cone-shaped through hole in the middle and corresponding to it. The upper and lower cylindrical through holes are formed through, and the hollow sealing member 2 is composed of a central cone and upper and lower positioning columns 2-1, 2-4 connected thereto, and in the middle of the hollow sealing member 2 The side of the cone and the parts close to the bottom of the cone are respectively designed with at least one upper and lower rib 2-2, 2-3. The...

Abstract

The invention discloses a needleless barotropic medicine-adding infusion connector. The connector comprises a shell and a hollow sealing part, wherein the inside of the shell is provided with a through-hole; and the shape of the hollow sealing part is matched with that of the through-hole of the shell and embedded in the through-hole. The connector overcomes the defect that when the existing intravenous needle and transfusion needle are used in venipuncture for blood transfusion and infusion or medicine injection treatment of the patient, repeated punctures for infusion may be performed for long time or liquid medicine is added temporarily many times in each infusion so as to cause unnecessary pains on the patient. The product of the invention ensures the infusion device and the infusion connector to be connected firmly, reduces or avoids the pains of the patient and is extremely beneficial for eliminating medical negligences. The infusion connector of the invention is a infusion connector not using a needle and can be widely used in the clinical infusions of central venous catheter, peripheral intervention central venous and the like in the aspect of medical treatments.

Description

1. Technical field [0001] The invention relates to an infusion joint, in particular to a needle-free positive pressure drug-dosing infusion joint which is used in medical treatment and can ensure firm connection between the infusion device and the infusion joint. 2. Background technology [0002] At present, in medical clinics, blood transfusion, infusion or drug injection through venipuncture is the most common method in the process of treating patients. However, in the treatment of venipuncture blood transfusion, infusion or drug injection by the existing medical staff, usually the venous needle and infusion needle puncture, due to the different conditions of various diseases or the limitations of the patient's own conditions, there may be long-term repeated Multiple puncture infusions or multiple temporary injections of medicinal liquid in the infusion pipeline in a single infusion will bring unnecessary pain to the patient. 3. Contents of the invention [0003] The pu...
