Description

A waterproof device for indwelling needles

technical field

The invention relates to the field of medical instruments, in particular to a waterproof device for indwelling needles.

Background technique

At present, intravenous indwelling needles have been widely used clinically. The venous indwelling needles are easy to operate and are suitable for puncture in any part, which not only relieves the pain of repeated punctures for patients, but also reduces the workload of nurses. welcome.

Due to the current promotion of zero tolerance for steel needles and the principle of venipuncture to protect blood vessels, indwelling needles are usually used on the back of the hand and arms-it is easy to get wet when washing hands and showering. In addition, due to the frequent movement of the patient's hand, the indwelling needle film is soft and thin, and it is often loose or accidentally pulled off, resulting in the indwelling needle not being able to continue to be used until the expected time before being replaced. Moreover, if the observation is not timely, falling off at night may increase the chance of infection due to bleeding at the puncture site of the indwelling needle. Therefore, it is necessary to design a device that is both waterproof and protected and can be operated with one hand.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a waterproof device for indwelling needles. The waterproof device for indwelling needles is put on the arm by one-handed operation, and then the disposable unsealing strips at both ends are opened, and the elastic ring of the annular plastic support is taken out automatically. Folded, it can be operated with one hand and plays a waterproof and protective role.

In order to solve the above problems, the present invention adopts the following scheme:

A waterproof device for indwelling needles, comprising a shaft sleeve body carried on an arm, and two ends of the shaft sleeve body are provided with fixing structures supporting openings at both ends.

In a further step compared with the above solution, interlayers are provided at both ends of the shaft sleeve body, and a fixing structure is arranged in the middle of the interlayers. The fixed structure acts as a support before being placed in the arm.

Compared with the above solution, a disposable unsealing strip is provided on the outside of the interlayer to seal the fixed structure in the middle of the interlayer. It is convenient to unpack with one-handed operation, so that the fixed structure can be taken out.

In a further step compared with the above solution, the fixing structure is a ring-shaped plastic support that is convenient for the arm to pass through.

Compared with the above solution, the sleeve body is provided with a disposable unsealing strip for opening the device after use from one end provided with the annular plastic support to the other end. Convenient one-handed operation to unpack and remove the device.

Compared with the above solution, the two ends of the sleeve body are provided with elastic rings that tighten the openings at both ends after the annular plastic support is removed. The elastic ring can better fit the skin to the device and prevent water from seeping in.

Beneficial effects: the shaft sleeve body is provided with a one-time unsealing strip for opening the device after use from one end with a fixed structure to the other end, so that it is convenient to disassemble directly with one hand, and the two ends of the shaft sleeve body are ring-shaped with sealing and fixing devices One-time unsealing strip, which is convenient for one-handed operation to unseal, so as to take out the ring-shaped fixation. The two ends of the shaft sleeve body are provided with elastic rings that tighten the openings at both ends after the fixing structure is removed, and it is close to the skin for waterproofing. The function, and the whole process can be completed with one hand.

Detailed ways

The present invention will be further described below in conjunction with the description, but the invention is not limited to the following examples.

As shown in Figure 1-2, the present invention includes a bushing body 1 that is carried on the arm. Both ends of the bushing body 1 are provided with a fixed structure 2 that supports the openings at both ends. The two ends of the bushing body 1 are provided with interlayers 101. A fixed structure 2 is arranged in the middle of the interlayer 101, and the fixed structure 2 is an annular plastic support 201 that is convenient for the arm to pass through directly. Both ends of the shaft sleeve body 1 are annularly provided with disposable unsealing strips 3 that seal the annular fixing device 201. When the waterproof device needs to be used, and the device has been worn on the arm, the two ends of the shaft sleeve body 1 can be sealed. The disposable unsealing strip 3 holding the annular fixing device 201 is torn apart, and then the annular plastic support 201 is taken out. At this time, the elastic ring 4 at both ends of the sleeve body 1 is closed to the arm because there is no constraint of the annular plastic support 201. The elastic ring 4. The inner ring is made of a material with a strong adsorption structure and waterproof. Pressing with your hand can make it more absorbent, so as to achieve the function of waterproof and protection, and can be completed with one hand. The shaft sleeve body 1 is also provided with a disposable unsealing strip 3 for opening the device after use from one end provided with the fixed structure 2 to the other end. After taking a bath, the disposable unsealing strip 3 can be unloaded. the device. When not in use or in transit, the device can be squeezed down so that it takes up little space.

At present, intravenous indwelling needles have been widely used clinically. The venous indwelling needles are easy to operate and are suitable for puncture in any part, which not only relieves the pain of repeated punctures for patients, but also reduces the workload of nurses. welcome. Due to the current promotion of zero tolerance for steel needles and the principle of venipuncture to protect blood vessels, indwelling needles are usually used on the back of the hand and arms-it is easy to get wet when washing hands and showering. In addition, due to the frequent movement of the patient's hand, the indwelling needle film is soft and thin, and it is often loose or accidentally pulled off, resulting in the indwelling needle not being able to continue to be used until the expected time before being replaced. Moreover, if the observation is not timely, falling off at night may increase the chance of infection due to bleeding at the puncture site of the indwelling needle. Therefore, it is necessary to design a device that is both waterproof and protected and can be operated with one hand.

Compared with the prior art, the shaft sleeve body 1 is provided with a disposable unsealing strip 3 for opening the device after use from one end with the fixed structure 2 to the other end, so that it is convenient to disassemble directly with one hand. The end ring is provided with a disposable unsealing strip 3 that seals the fixed structure 201, which is convenient for unsealing by one-handed operation, so that the annular plastic support 201 can be taken out. The elastic ring 4 with openings at both ends is tightly attached to the skin to play a waterproof role, and the whole process can be completed with one hand.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand; The recorded technical solutions are modified, or equivalent replacements are made to some of the technical features; these modifications or replacements do not mean that the essence of the corresponding technical solutions deviates from the spirit and scope of the technical solutions of the various embodiments of the present invention.
