The invention is suitable for the mechanical technology field, and provides a surgical planning method and system for the percutaneous puncture. In order to realize the above purpose, the invention provides a surgical planning method for the percutaneous puncture. The method comprises the following steps of: A) obtaining the mechanical image data of a patient; B) according to the mechanical image data, reconstructing the three-dimensional model of the relevant organ and/ or tissue and/ or focus of the patient; and C) determining the surgical operation process of the percutaneous puncture on the three-dimensional model by a virtual puncture device. Therefore, according to the invention, a user can repeatedly carry out the skin puncture operation by the virtual puncture device so as to accurately obtain the skin puncture point, the angle and the puncture path of the patient.

A skin puncture device for use as an intravenous catheter or blood collecting needle set is provided with a mechanism for protection against needle injury and access to fluid passageway during insertion. The assembly includes a flexible extension tube connected to the proximal end of the needle housing for use in difficult insertion sites. The extension tube provides access for fluid injection so that the passageway and needle can be filled with fluid prior to needle/catheter insertion, allowing diffusion of blood to provide evidence of successful venipuncture and allowing the infusion of small amounts of fluid into the vein to facilitate catheter advancement. The locking mechanism consists of two apertures in the needle housing and two pairs of needle guard locking tabs which selectively engage when the needle guard is pushed forward to its fully extended position upon completion of insertion or blood drawing, encapsulating the length of the needle.

Provided is a microneedle device which protects a microneedle, has an easily portable shape, is free from such problems as breakage of small needles in the step of puncturing the skin with the microneedle, and ensures appropriate skin puncture to administer a drug. By studying the relationship between the device to be pressed to the skin and the height of the elevation of the skin surface during the pressing, it is found that there is a positive correlation between the placement and interval of skin fixing members and the height of the elevation of the skin. It is furthermore found that the elevated skin surface is always parallel to the flat plate of the device. This reveals that since the microneedle installed in the device can be inserted at right angle to the skin surface, the skin can reliably be punctuated avoiding the breakage etc. of the small needles of the microneedle. Thus, a microneedle patch which is easily portable and ensures convenient drug administration to the skin can be produced.

An apparatus for removing a pigmented section of skin, comprises a) a skin puncturing device; b) an array of one or more needles connected to said device for puncturing the skin at said pigmented section; and c) a mediating member attached to said device and to suction means, for allowing said suction means to collect the mixture of the pigments with the cellular fluids at said punctured section of the skin.

Provided is a microneedle device which protects microneedle, has an easily portable shape, is free from such problems as breakage of small needles in the step of puncturing the skin with the microneedle, and ensures appropriate skin puncture for administering a drug. By studying the relationship between a device to be pressed to the skin and the height of an elevation on the skin surface under the pressing and thus producing a device equipped with microneedle that are embedded in a concave part having a definite depth, the microneedle can be surely and easily inserted and punctured into the skin while avoiding such problems as breakage of the small needles of the microneedle. Thus, a microneedle patch formulation, which is easily portable and ensures convenient drug administration to the skin, can be produced.

Disclosed is an assistance device which can be used for the puncture into the skin with a puncture tool having a puncture needle and the measurement of a desired component in the blood with a blood glucose monitoring system equipped with a measurement tool. The assistance device comprises a main body which contacts with the skin and a lid which is connected to the main body in a freely openable and closable manner, wherein one of the main body and the lid has a puncture guide for positioning the puncture needle toward a position on the skin to be punctured with the puncture needle, and the other has a blood collection guide for positioning the measurement tool toward the position on the skin punctured with the puncture needle.

The present invention is a method of preventing reuse of test strips for measuring an analyte or indicator such as glucose in a physiological fluid such as blood, interstitial fluid, or urine. The present invention also relates to a method of preventing reuse of test strips incorporating an integrated lance such as a needle, blade, or other sharp or skin puncturing device. Certain types of medical devices such as, for example, glucose test strips were intended to be tested only once and then disposed. This requirement is often needed because the reagent chemistry in many test strips is not suitable for measuring glucose a second time. However, it is possible that some user will accidentally test a previously used test strip. This could potentially become a problem if the glucose meter attempts to make a glucose measurement and outputs a result. Therefore, it is desirable that a single use test strip and meter have a prescribed method for preventing a previously tested test strip from being reused.

The medical puncturing device (10) includes a housing (12) having a proximal end (18) and a distal end (16) and a skin puncturing assembly (14) within the housing. The skin puncturing assembly includes a movable carrier (50) and a skin puncturing element (52). The skin puncturing element is adapted to puncture the skin of a patient. The carrier is movable from a retracted position wherein a distal tip of the skin puncturing element is disposed within the housing, to a puncturing position wherein the distal tip is exposed to puncture the skin of the patient. The carrier is moved from the retracted position to the puncturing position upon radial deformation of the housing. An internal guide (42) may be provided within the housing for guiding the movement of the carrier from the retracted position to the puncturing position.

A needle free injector system and a method for delivering a formulation using this system are disclosed. The method comprises actuating a needle free injector to pressurize a liquid formulation and force the formulation through an orifice in a skin puncture phase followed by injection of the formulation during a delivery phase. The skin puncture phase is defined by a pressure profile vs. time curve after actuation which has a main pressure peak with a maximum pressure. The delivery phase occurs at a lower pressure than the maximum pressure of the main peak pressure. The device may have one or more orifices and pressurizing the formulation during the puncture phase and delivery phase to extrude the formulation through each orifice is structured so as to improve characteristics of needle free delivery.

The present invention relates to a method for removing pigments from a pigmented section of a skin by puncturing the skin at the pigmented section, with a skin puncturing device which is provided with at least one needle, and then bandaging the punctured section with a suitable adsorbing pad. The pad contains one or more materials, such as saline, which will cause the pigments at the punctured section to migrate into the outer layer of the skin.
