Embodiment 1

[0049] Embodiment 1: The manufacturing process of the needle-free medicated joint, such as figure 1 As shown, the medicated joint includes an inner sleeve 1 with a liquid hole 11, a shell 3 with a liquid hole 31, and a rubber plug 2. The liquid hole 31 communicates with the liquid hole 11 and is used as a normal infusion. The combination between the inner sleeve 1 and the outer shell 3 forms a sampling chamber 101 for the rubber plug 2 to engage and prevent the rubber plug 2 from escaping.

[0050] The rubber plug 2 is made of vulcanized silica gel. The rubber plug 2 includes a base 21, an inner convex portion 22 protruding toward the liquid hole 11 relative to the base 21, and an outer convex portion 23 facing outward relative to the base 21. The inner convex portion 22 is a cylinder. The outer convex part 23 and the base part 21 are elliptical cylinders, and the projection planes of the outer convex part 23 and the inner convex part 22 all fall in the projection plane of the...

Abstract

The invention relates to a manufacturing process of a needle-free drug-feeding joint. The process includes the following steps: Step S1, one-shot injection molding to form an inner casing with a liquid hole, and forming a The inner plug seat of the sampling chamber, wherein the sampling chamber is connected to the liquid hole; step S2, preparation of the rubber plug, inserting the formed rubber plug into the incision of the tooling equipment and applying silicone oil to the incision; step S3, installing the rubber plug, putting the rubber plug The plug is embedded in the sampling cavity, and the cutout is communicated with the liquid hole; step S4, secondary injection molding, injection molding to form a shell, the shell wraps the inner sleeve and forms a liquid hole connected to the liquid hole, and wraps the rubber plug to form an outer plug The seat is connected to the inner plug seat to tightly restrict the rubber plug to the sampling chamber; the outer plug seat is provided with a sampling opening connected to the sampling chamber; it has good positioning effect between the rubber plug and the sampling chamber, strong structural stability, The advantages of good sealing.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a manufacturing process of a needle-free drug-feeding joint. Background technique [0002] In the process of infusion to clinical patients, medical staff need to temporarily add drugs according to the patient's medication status and / or condition changes; similarly, in the process of drainage of postoperative patients such as patients after thoracic or abdominal surgery In order to dynamically grasp the pathological conditions of patients, medical staff need to take samples of drainage fluid in order to provide accurate information for taking necessary treatment measures, such as adjusting or changing the medication for patients; Urine samples from patients with urine, there are also temporary sampling situations, etc., so the joints with sampling function are usually applied to infusion tubes and drainage tubes. [0003] The Chinese patent with application publication number CN1...
