Description

Indwelling needle warning structure

technical field

The utility model relates to the technical field of medical equipment, in particular to an indwelling needle warning structure.

Background technique

Indwelling venous needles are also called venous trocars. The core components include a catheter and a flexible cannula that can be indwelled in the blood vessel, and a stainless steel puncture guide needle core. When in use, the cannula and the needle core are punctured into the blood vessel together. When the cannula is completely inserted into the blood vessel, the needle core is withdrawn, and only the soft cannula is left in the blood vessel for infusion therapy. In this way, patients do not need multiple needle insertions during infusion, which reduces the pain of patients, especially children's fear of needle insertion, reduces the anxiety of parents, facilitates clinical medication, rescue medication for emergency and critically ill patients, and relieves nurses' work. quantity. However, with the current indwelling needles, due to patient activities, fluid (blood or medicinal liquid) leakage and improper shedding often occur at the indwelling needles. These unexpected situations are difficult for patients and nurses to directly judge, which may easily lead to medical services. Reduced quality.

Utility model content

The purpose of the utility model is to provide an indwelling needle warning structure to solve the problem of the indwelling needle falling off improperly in the prior art.

The plan is basically as follows:

The indwelling needle warning structure includes a strap that can wrap a patient's hand, a casing is fixed on the strap, a fixing part for fixing the indwelling needle is arranged on the strap and the casing, and the fixing part is detachably connected with the indwelling needle.

Beneficial effects: after the indwelling needle is punctured, the band wraps the patient's hand, and the indwelling needle can be fixed by the band and the fixing part on the housing, so as to avoid the accidental falling off of the indwelling needle.

Further, the strap is an elastic strap. In this way, the band can further press the indwelling needle through the elastic force, so as to improve the fixation of the indwelling needle.

Further, the fixing part on the strap is an arc-shaped elastic ferrule. The indwelling needle can be fixed by pressing the indwelling needle into the card sleeve, and the operation is simple and convenient.

Further, the fixing portion on the housing is a fixing groove that can be matched with the conduit. The fixing groove can fix the catheter of the indwelling needle, and further avoid the influence of the movement of the catheter.

Further, a thumb hole is provided on the strap. The thumb hole is convenient for the thumb to pass through, which is convenient for the positioning of the strap relative to the hand.

Further, the ferrule is embedded on the strap. The card sleeve is embedded in the belt, and is fixed on the surface of the belt relative to the card sleeve, which can reduce the pressure of the card sleeve on the skin of the hand.

Further, the strap is provided with an opening corresponding to the puncturing position, and a mesh window is fixed in the opening. It is beneficial to observe the puncture position later and at the same time facilitate the ventilation of the puncture position.

Further, a sensor is fixed on the strap, the sensor is fixed on the surface of the strap attached to the hand and corresponds to the puncture position of the indwelling needle, and the sensor is connected with a warning device.

The sensor can detect whether there is liquid seepage at the puncture position. If there is liquid seepage, the sensor will give a signal to the warning device to warn, so as to help medical staff to deal with it in time.

Further, the warning device adopts a flasher or a buzzer. The flash or buzzer is low cost and small in size.

Further, both ends of the strap can be connected by Velcro. It is convenient for the strap to be fixed with the hand, and the operation is convenient.

Detailed ways

The following is further described in detail by specific embodiments:

Reference numerals in the drawings include: strap 1 , thumb hole 11 , clip 12 , sensor 13 , housing 2 , warning device 21 , fixing slot 22 , grid window 14 , positive electrode 8 , negative electrode 9 .

The first embodiment is basically as follows:

The indwelling needle warning structure, as shown in Figure 1, includes a strap 1, the strap 1 is made of elastic fabric, and the two ends of the strap 1 can be bonded by Velcro. A housing 2 is fixed on the strap 1, and a single chip (STM8), a circuit board and a power supply are installed in the housing 2, and the power supply adopts a battery. As shown in Figures 1 and 2, the microcontroller is connected to a sensor 13, which can be an ion sensor (eg, a 701 ion probe). The microcontroller is also connected to a warning device 21, which can be a flasher or a buzzer.

A ferrule 12 for fixing the indwelling needle is adhered and fixed on the surface of the strap 1 which is attached to the human skin. The ferrule 12 is made of elastic rubber. As shown in FIG. With an opening, the indwelling needle can be pressed into the ferrule 12 to be fixed. The housing 2 is provided with a fixing groove 22, which can further fix the catheter of the indwelling needle.

As shown in FIG. 1 , the strap 1 is further provided with a thumb hole 11 for extending the thumb of the patient and facilitating the positioning of the strap 1 .

When in use, the two ends of the strap 1 are unfolded as shown in Figure 2. First, put the patient's right palm on the strap 1, and pass the patient's thumb through the thumb hole 11, and then insert a needle to puncture the blood vessel. The left end of the belt 1 goes around the palm of the hand and is properly stretched by pulling force. The sensor 13 is attached to the puncture position, and the indwelling needle is pressed into the ferrule 12 at the corresponding position. Finally, the left end and the right end of the belt 1 are bonded to obtain state as shown in Figure 1. The indwelling needle catheter is then bypassed above the band 1, and is further fixed by the fixing groove 22, as shown by the dotted line in FIG. 1 . The band 1 can fix the catheter of the indwelling needle, further reducing the accidental fall of the indwelling needle. If blood or medicinal liquid seeps out, the sensor 13 detects the liquid, and the sensor 13 can feed back a signal to the warning device 21 to make the warning device 21 remind.
