Description

lancet fixing device

technical field

The utility model relates to the field of medical equipment, in particular to a blood collection needle fixing device.

Background technique

In the current medical and health industry, doctors will use blood collection needles to collect blood from patients to achieve the purpose of disease detection, prevention or treatment of diseases. Existing blood collection needles include needles, handles, blood collection tubes, etc. When in use, the doctor holds the handle and stabs the needle into the blood vessel to collect blood. After the needle enters the blood vessel, the doctor needs to manually press the handle to fix the tail of the needle, which is convenient for subsequent use of medical tapes on the needle. It is fixed to prevent the needle from falling off during the blood collection process, resulting in a second blood draw for the patient. In the process of blood collection, the hand needs to be pressed on the handle all the time, and the doctor cannot perform other medical work, which brings a lot of inconvenience to the doctor, thus affecting the quality of medical care.

Utility model content

The purpose of the utility model is to provide a blood collection needle fixing device, so as to realize the automatic fixation of the blood collection needle during the blood collection process without manual pressing.

In order to achieve the above purpose, the basic technical scheme of the present invention is as follows: a blood collection needle fixing device includes a base, an arm support is fixed on the base, a gland is arranged on the top of the arm support, and one end of the gland is rotatably connected to the arm support, and the gland is connected to the arm support. There is a locking mechanism between the other end of the arm rest and the arm rest, the part of the gland facing the arm rest is provided with a first groove, a first air bag is provided in the first groove, and the part of the arm rest facing the first groove There is a second groove, a second air bag is arranged in the second groove, a hot air blower is arranged in the base, a first air duct is connected between the hot air blower and the first air bag, and a first air duct is connected between the hot air blower and the second air bag. Second airway.

The working principle of the blood collection needle fixing device is as follows: place the base on the desktop, open the locking mechanism, and turn the gland to rotate the gland, thereby opening the top of the arm rest. Put the patient's forearm on the second groove on the top of the arm rest, start the hot air blower, and the hot air blower fills the first air bag and the second air bag with hot air through the first air tube and the second air tube respectively. The second air bag inflates. After the doctor inserts the needle of the lancet into the patient's forearm, turns the gland, closes the gland on the arm support, and locks it through the locking mechanism, the lancet can be pressed and fixed through the gland without manual pressing of the lancet. ,easy to use.

When the above technical solution is adopted, the arm support, the gland and the airbag can support and position the human forearm, and the inserted blood collection needle can be pressed and fixed without being fixed by adhesive tape, thus saving the adhesive tape and requiring no continuous pressing by hand. , reduces the work intensity of the doctor, is easy to operate, and can ensure that the blood collection needle will not move during use. The airbag can massage the patient's forearm to a certain extent, preventing the patient's forearm from being clamped by the arm support and the gland for a long time, resulting in soreness. In addition, the hot air filled in the air bag makes the air bag have a certain temperature, which protects and shields the arm, heats and warms the arm in a cold environment, makes the arm more comfortable, and also prevents the blood vessels from contracting due to the cold environment. The blood flow is smoother, and blood collection is more comfortable and quicker. The gland can also cover the blood collection site, so that the blood collection person will not see the blood collection site, which is more suitable for blood collection for people who are fainted.

Further, the arm rest and the base are welded, and the arm rest and the base form an included angle of 90 degrees. Welding is a common fixed connection method. Through welding, the arm support can be fixed on the base more firmly, and the service life of the device is improved. The arm rest is perpendicular to the base. When the patient's arm is placed on the arm rest, the base is subject to the vertical downward pressure of the arm rest, so that the base is vertically pressed on the desktop, and the arm rest has no horizontal effect on the base. Therefore, the base will not slide on the desktop by the lateral force given by the arm rest, so that the base is more stable.

Further, the locking mechanism includes a magnet and an iron block, the magnet is located on the arm support, and the iron block is located on the gland. The gland can be fixed on the arm support through the attraction of the magnet and the iron block. When the gland is not required, the gland and the arm support can be separated with a little force, and the operation is simple and convenient.

Further, the first airbag and the second airbag are provided with a plurality of horizontal rubber tubes and vertical rubber tubes, the vertical rubber tubes are all connected with the horizontal rubber tubes, the first air guide tube is connected to the vertical rubber tube in the middle of the first airbag, and the first airbag is connected to the vertical rubber tube. The second air tube is connected to the vertical rubber tube in the middle of the second air bag. The horizontal rubber tube and the vertical rubber tube are criss-crossed in the air bag, which can fully inflate all parts of the air bag and fully support the arm. The first air tube is connected to the vertical rubber tube in the middle of the first air bag, and the second air tube is connected to the vertical rubber tube in the middle of the second air bag, so that when inflated, the gas diffuses and flows from the middle of the air bag to both sides, ensuring the air bag. Uniform expansion on both sides.

Further, the number of vertical rubber tubes in the first airbag is greater than the number of vertical rubber tubes in the second airbag, and the diameter of the vertical rubber tubes in the first airbag is smaller than the diameter of the vertical rubber tubes in the second airbag. When the patient collects blood, the front of the forearm should face the gland, the back of the forearm should face the arm support, and then the doctor should hold the blood collection needle to puncture the blood vessel on the front of the forearm. Therefore, the number of vertical rubber tubes of the first air bag on the gland is large, which can ensure that the front of the forearm is fully squeezed by the first air bag, ensuring the comfort of the patient during blood collection, and the second air bag on the arm rest is vertical. The number of rubber tubes has little effect on blood collection, so the number of vertical rubber tubes can be reduced to achieve the purpose of saving materials. The smaller diameter of the vertical rubber tube of the first air bag can reduce the gap between the vertical rubber tubes in the first air bag, and also to ensure that the front of the forearm is fully squeezed by the first air bag to ensure the comfort of the patient during blood collection .

Further, the bottom of the base is provided with a suction cup. The suction cup can adsorb the base on the desktop, prevent the base from sliding on the desktop, and improve the stability of the base during use.

Further, the arm support and the pressure plate are rotatably connected by a pin shaft. The pin shaft connection is a common rotary connection method, and the pin shaft is a standard part, which is easy to purchase and configure, and the pin shaft connection is a detachable connection, which is convenient for the removal and installation of the arm support and the gland, and is easy to carry.
