Description

Transfusion needle fixing plaster

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a transfusion needle fixing application.

Background

The infusion needle usually comprises a needle handle and a needle head, wherein the needle head of the infusion needle is inserted into a vein of a human body during infusion operation, and the needle handle is fixed on the arm or the back of the hand of the human body.

At present, a medical adhesive tape is usually used for fixing an infusion needle, but by using the mode, the adhesive tape can only be bound and fixed along the vertical direction of the puncture direction of the infusion needle, and the needle head of the infusion needle generally retreats backwards in the puncture direction and falls off, so that the effective fixing effect of the fixing mode on the infusion needle is weaker. Meanwhile, in some cases, such as when a child patient is treated with infusion or when a patient with an indwelling infusion needle needs to be taken off the clothes in an image examination, the infusion needle is more likely to fall off by using a traditional fixing mode.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the prior transfusion needle fixing mode proposed in the background has weak fixing effect.

In order to achieve the above object, the utility model provides a following technical scheme:

a transfusion needle fixing application comprises a fixing layer, wherein one surface of the fixing layer is paved with an adhesive layer, the other surface of the fixing layer is provided with a sliding groove, and a first fixing piece and a second fixing piece are slidably mounted in the sliding groove; the first fixing piece is fixedly connected with one end of the sliding groove through a first elastic piece, and the second fixing piece is fixedly connected with the other end of the sliding groove through a second elastic piece; the first fixing piece and the second fixing piece are used for fixing a needle handle of the infusion needle in the puncture direction of the infusion needle.

It can be understood that, when the infusion needle is fixed and is applied ointment or plaster to use that this scheme discloses, need paste the layer and paste at human infusion position, after the infusion needle syringe needle pierced human blood vessel, place the needle handle of infusion needle on the fixed layer of this device, and be located between first mounting and the second mounting. The design of the first elastic piece and the second elastic piece ensures that the first fixing piece and the second fixing piece have a tendency of being close to each other (namely, the design length of the spring is satisfied, when the spring naturally expands, the width between the first fixing piece and the second fixing piece is smaller than the width of the needle handle in the puncture direction of the infusion needle), and the needle handle of the infusion needle can be limited and fixed in the puncture direction by the first fixing piece and the second fixing piece through the pressure exerted by the first elastic piece and the second elastic piece, so that the infusion needle is prevented from being further penetrated forward or falling off towards the back needle head.

Further, the first fixing piece comprises a first sliding block, a first supporting column and a first limiting plate; one end of the first support column is fixedly connected with the other end of the first limiting plate and fixedly connected with the top end of the first sliding block, and the first sliding block is slidably mounted in the sliding groove; the first elastic piece is arranged in the sliding groove, one end of the first elastic piece is fixedly connected with one side of the first sliding block, and the other end of the first elastic piece is fixedly connected with one end of the sliding groove;

the second fixing piece comprises a second sliding block, a second supporting column and a second limiting plate; one end of the second supporting column is fixedly connected with the other end of the second limiting plate and is fixedly connected with the top end of the second sliding block, and the second sliding block is slidably mounted in the sliding groove; the second elastic piece is installed inside the sliding groove, one end of the second elastic piece is fixedly connected with one side of the second sliding block, and the other end of the second elastic piece is fixedly connected with the other end of the sliding groove.

Meanwhile, the inner wall of the limiting cap is arranged to be an inclined plane, when the limiting cap is used, the first limiting plate and the second limiting plate can be covered at different intervals at the same time (the shapes of needle handles of different transfusion needles are the same, but the width sizes of the needle handles are slightly different, when the needle handles fixed by the first limiting plate and the second limiting plate are large-width needle handles, the interval between the first limiting plate and the second limiting plate is relatively large, at the moment, when the limiting cap covers the main first limiting plate and the second limiting plate at the same time, the first lug and the second lug can be embedded into the groove which is relatively close to the bottom surface in the limiting cap, and when the needle handles fixed by the first limiting plate and the second limiting plate are small-width needle handles, the first lug and the second lug can be embedded into the groove which is relatively close to the top layer in the limiting cap).

Furthermore, the first lug, the second lug and the limiting cap are all made of rubber materials.

It can be understood that the rubber has better deformability and softness, is non-toxic to a human body, and is convenient to quickly cover and pull out the limiting cap by using the lugs and the limiting cap made of the rubber material.

Furthermore, a first limiting groove is formed in the inner wall of the first limiting plate, a second limiting groove is formed in the inner wall of the second limiting plate, and the first limiting groove and the second limiting groove are used for limiting the needle handle of the infusion needle.

It can be understood that the limiting grooves can be formed in the facing surfaces of the two limiting plates, the width of each limiting groove is larger than or equal to the thickness of the infusion needle handle, and when the first limiting plate and the second limiting plate clamp the infusion needle handle, the two ends of the infusion needle handle in the puncture direction are respectively located in the first limiting groove and the second limiting groove. The design is convenient for further fixing the transfusion needle handle, and improves the using effect of the device.

Further, the fixed layer is made of a silica gel material.

It can be understood that the silica gel has better softness and comfort level, is harmless to the human body, is convenient for the installation of the sticking layer, and is favorable for improving the use comfort level of the device by using the fixing layer made of the silica gel.

Furthermore, a plurality of air holes are arranged on the fixed layer.

It can be understood that the design of gas pocket, this device of being convenient for has better gas permeability after laminating human skin, further improves the comfort level of this device.

Furthermore, the adhesive layer is made of medical pure natural maleic glue or a nontoxic acrylic coating.

It can be understood that the medical pure natural maleic glue or the nontoxic acrylic coating is a common medical glue material on the market, has good fitness of being jointed with the skin of a human body, and is harmless to the human body.

In summary, the utility model provides a transfusion needle fixing application, which solves the defects of weak fixing effect, short fixing time and the like of the traditional transfusion needle fixing mode; meanwhile, the device is simple to operate, attractive in appearance and good in market prospect.
