Embodiment Construction

[0077] will now refer to figure 1 -2e describes in more detail an embodiment of the medical pump according to the present invention.

[0078] The medical pump 1 comprises a liquid reservoir 3, a tubular element 7 and an outer seal 9, wherein the liquid reservoir 3 is used to contain a fluid 5, the tubular element 7 is arranged in the liquid reservoir 3, and the outer seal 9 The seal 9 extends between the inner wall 11 of the reservoir and the outer wall 13 of the tubular element 7 . The tubular element 7 is provided with an internal seal 15 which can be in an advanced position inside the tubular element 7 (see figure 1 and 2a) and the retracted position (see Figure 2c). The inner seal 15 is retractable from the advanced position to the retracted position, so that the fluid 5 is diverted from the part of the reservoir 3 surrounding the tubular element 7 into the inner space 21 (see FIG. 2c ), which is formed by The retracted inner seal 15 is bounded by the tubular element 7 ...

Abstract

A medical pump, comprising a reservoir having a fluid enclosing portion and a tubular element, the inside of which is arrangeable in fluid communication with the fluid enclosing portion for allowing fluid to pass into the tubular element. The fluid enclosing portion contains a volume of fluid sealed from communication with air and the fluid enclosing portion is adapted to reduce in volume essentially to the same extent as any volume of fluid transferred into the inside of the tubular element. The invention also relates to a method of delivering a medical fluid.

Description

technical field [0001] The present invention relates to a medical pump and to a method of delivering medical fluid. In this application, it is to be noted that the term fluid includes not only fluids, but also gels. Background technique [0002] Syringes and other injection equipment have different applications. One of the syringes is used to administer fluids with viscosities higher than 1000 mPa*s, such as gels. For example, the gel can be injected into the skin of a human or animal to increase the volume of the skin. Such applications have been used in the cosmetic industry, eg for smoothing wrinkles or creases, contouring the face, tattooing lips, etc. For example, such gels are marketed by the applicant under the trade names Restylane and Perlane, which are based on so-called NASHA-gels (Non-Animal Stabilized Hyaluronic Acid). Another application is the injectable gel to treat urinary incontinence in women. The applicant registered this gel under the trade name Zui...
