Abstract
The invention discloses a multi-point needle-free injection ampoule device which comprises an ampoule shell, a piston, a piston drive rod and a split type injection head. The ampoule shell is used for containing liquid medicine. The piston is disposed in the ampoule shell. The piston drive rod is connected with the piston and drives the piston to move back and forth in the ampoule shell. The split type injection head is disposed on the outer side of a liquid medicine access of the ampoule shell. The liquid medicine access comprises n liquid outlets, one end of each liquid outlet is a conical inlet, and the other end of each liquid outlet is a cylindrical outlet; n conical injection pores are evenly formed inside the split type injection head, and the n conical injection pores and the n liquid outlets are in one-to-one correspondence in position; wherein n is not smaller than 2, and n is an integer. The multi-point needle-free injection ampoule device is small in size, simple in structure, and suitable for large-area wound multi-point subcutaneous or intracutaneous local areas. By the split medicine taking device, medicine taking efficiency can be increased, and injection performance of the medicine is unaffected.
Description
Technical field
The present invention relates to a kind of injection ampoule device, especially a kind of multiple spot Needleless injection ampoule device.
Background technology
The local subcutaneous infiltration anesthesia is the common method of clinical operation anesthesia and Postoperative Analgesia After, as the anesthesia of the local operations such as opening sexual trauma, anorectal section and department of obstetrics and gynecology, and department of general surgery and other surgical operation front that the infusion of medicine cutting edge is subcutaneous for Postoperative Analgesia After etc. in sewing up the incision, for forming regional area anesthesia or analgesic effect, usually use the local multiple subcutaneous injections medicine of ordinary syringe during anesthesia, anaesthetic scatters by a plurality of injection points, forms local regional anesthesia.The defect of this anesthesia injecting method is that the anesthesia amount of each injection point is controlled voluntarily by clinical experience by the doctor and increased the anesthesia required time, the inequality that medicine scatters and causes topical remedy to distribute from injection point simultaneously, in addition, preoperative multiple injection can increase patient's misery.The pain that when Needleless injection can effectively alleviate or eliminate injection, acupuncture causes, the injection head of the needleless injector adopted in the market and ampoule housing adopt integrated structure design, injection micro-pore diameter on injection head is very little, and be generally single hole, its effect is mainly the hydraulic energy of medicinal liquid to be converted into to greatest extent to the kinetic energy of jet, but equally because the injection micro-pore diameter is very little, make the efficiency of getting it filled of injection ampoule device not high, and the medicine taking device structure is more complicated, use inconveniently, be not suitable for carrying out the subcutaneous or intradermal injection of regional area multiple spot; Simultaneously integrated structure design is very high for the injection molding performance requirement, and the cooperation of dynamic model and cover half will be very accurately, thus easily cause the fraction defective of product and production cost higher.
