DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0027] A special pillow for radial artery blood gas collection, such as Figure 1-Figure 4 As shown, including:

[0028] A base 1, a box cover 2 arranged on the base 1, and a power supply, wherein a passage for an arm to pass through is formed between the base 1 and the box cover 2;

[0029] A support surface 3 for placing the arm is provided at the upper end of the base 1 corresponding to the channel, and an inclined support surface 4 is provided on one side of the base 1. Preferably, the angle between the inclined support surface 4 and the support surface 3 is 120°-150°, and the support surface 3 and the inclined support surface 4 have a smooth transition; the support surface 3 has a concave surface 5 for supporting the arm, and the concave surface 5 is provided with a heating module. Heating by the heating module is helpful to relieve vascular contraction and facilitate puncture operation. The concave surface 5 extends to the inclined support surface 4, and the concave surface 5 can also continue to extend downward along the inclined support surface 4. The setting of the concave surface 5 provides support for the placement of the arm, and also locates the placement position of the arm, ensuring that the airbag pressure block can accurately compress the radial artery and ulnar artery at the arm after the arm is inserted into the channel.

[0030] Three airbag-type pressing blocks are provided in the corresponding channels of the box cover 2, and airbag-type pressing blocks are provided in the corresponding airbag-type pressing blocks in the base 1, respectively, with air pump devices for inflating the airbag-type pressing blocks. The power supply is for the air pump device and the heating module. As the preferred power supply, a plug-in power supply is adopted, and an external power supply is inserted through a power plug. A power switch 14 is provided correspondingly at the base. When plugged in for use, the power switch 14 of the base needs to be turned on for use, so as to improve the safety performance.

[0031] A gas pipeline is provided in the box cover 2, and the airbag-type pressing blocks are connected to the corresponding air pump devices through the gas pipelines. In this embodiment, the air pump is a miniature air pump of the Hilintec brand D17 / D17S model. The airbag is equipped with an inflation port and an exhaust port. The air pump is connected to the inflation port through a gas pipeline to inflate the airbag; the exhaust port is connected to the solenoid valve, and the air pump and the solenoid valve are controlled by a knob-type switch. For example, the air pump is powered on to start inflation while the solenoid valve is powered off and closed, and the solenoid valve is powered on to open while the air pump is powered off and stops inflating.

[0032] The airbag pressure block corresponds to the upper part of the arm and the radial artery and ulnar artery of the arm, such as Figure 1 As shown, the airbag press block includes a first airbag press block 6, a second airbag press block 7 and a third airbag press block 8. The first airbag press block 6 is arranged between the second airbag press block 7 and the third airbag press block 8. Figure 4 As shown, the first airbag pressing block 6 is directly opposite to the position above the arm. Since the patient may be left or right hand when entering the channel, one of the second airbag pressing block 7 and the third airbag pressing block 8 corresponds to the radial artery of the arm, and the other corresponds to the ulnar artery of the arm; a puncture operation space is provided above the base 1 on one side of the box cover 2 close to the inclined support surface, such as Figure 3 As shown, there is no box cover at the puncture operation space, so that the arm is exposed.

[0033] Allen test process: The second and third airbag pressure blocks are inflated at the same time to compress the radial and ulnar arteries on both sides of the arm. The patient repeatedly clenches and opens his fingers 5-7 times until the palm turns white. The airbag pressure block that compresses the ulnar artery is exhausted, and the compression of the radial artery is maintained. The color change of the palm is observed. If the palm color quickly turns red or returns to normal in <10 seconds, it is a positive Allen test, and radial artery blood gas collection can be performed; if the palm is still pale after 10 seconds, the Allen test is negative, and it is not recommended to continue radial artery blood gas collection. When collecting radial artery blood gas, three airbag pressure blocks are inflated to fix the patient's arm.

[0034] The airbag type pressing block includes an airbag 9 and a hard pressing block 10 integrally connected with the airbag 9. Figure 4 As shown, the hard pressing block 10 is made of common plastic materials such as polyethylene materials, polyvinyl chloride materials, etc., and the airbag 9 is a common rubber airbag. The hard pressing block 10 can be bonded to the outside of the airbag. When the airbag 9 is inflated, the hard pressing block 10 gradually fits the skin and compresses the artery, replacing the human body to perform the Allen test. In this embodiment, the airbag is cylindrical after inflation, and the side of the hard pressing block that contacts the skin forms a curved surface.

[0035] As a preferred embodiment, a fixing belt 11 for fixing the palm is further provided at the inclined support surface 4, and the fixing belt 11 is an elastic fixing belt. Figure 3As shown, the patient's palm is restrained by the fixing belt 11 so that the palm is bent relative to the arm to prevent the patient's palm from moving during the puncture process.

[0036] The heating module includes a heating plate and a temperature control knob. The temperature control knob adopts a variable resistance knob. The power supply is for the heating plate. The heating plate is such as a PET heating film, an FPC heating film, etc. The temperature is adjusted or the power supply of the heating plate is turned off by the temperature control knob. A flexible cushion is provided on the concave surface. The flexible cushion can be made of leather, textile fabric, artificial leather, etc., or a sponge block can be used to increase comfort. The heating plate is laid under the flexible cushion. When the arm is placed in the concave surface, the position in contact with the human skin is heated by electric heating, which can relieve vasoconstriction and improve comfort.

[0037] Preferably, a temperature detection device for measuring the temperature near the concave surface 5 can also be arranged in the channel, such as a common liquid expansion thermometer, an infrared thermometer, a thermistor thermometer, etc. If a thermistor thermometer is used, a temperature display screen 13 can also be arranged on the side of the box cover for easy observation by medical staff.

[0038] Preferably, the base 1 or the box cover 2 is further provided with an audio player 12, which may be a built-in speaker, and the audio data may be transmitted through a data cable, Bluetooth, wifi, etc. The audio may be music played to relieve the patient's tension, and a voice broadcast reminder may also be made according to the content stored in the audio player. When the audio player's voice broadcasts, the patient may be prompted to place his arm on the support surface when drawing blood, and after 1-2 broadcasts, music may be played to relieve the patient's tension, and after the music is played, the patient may be prompted to press the blood drawing wound for 5-10 minutes.

[0039] As a preferred embodiment, the box cover of the utility model can be flipped open relative to the base, the box cover and the base are hingedly connected on one side of the channel, and a locking structure is provided between the box cover and the base on the other side of the channel. The state of the locking structure changes as follows: Figure 5As shown, it includes a lock hook 15 connected to the box cover 2, and a lock hook groove is provided on the upper end surface of the base 1 corresponding to the lock hook 15. When the box cover 2 is flipped and buckled on the base 1, the lock hook 15 is inserted into the lock hook groove, and a lock tongue 16 is provided in the lock hook groove corresponding to the lock hook. The lock hook 15 is provided with an arc surface corresponding to the lock tongue 16. During the downward movement of the lock hook 15, the arc surface pushes the lock tongue 16 below the lock hook 15 to translate to one side. After the lock tongue 16 is reset under the action of the reset spring 17, the lock hook 15 hooks the lock tongue 16 to achieve the purpose of locking; when it is necessary to open the locking device, a push rod 18 is provided in conjunction with the lock tongue 16, and the reset spring 17 is sleeved on the outside of the push rod 18, pressing the pressing block 19 at the end of the push rod 18, and the push rod 18 compresses the reset spring 17 to make the lock tongue 16 translate relative to the lock hook 15 to achieve unlocking; as a preferred embodiment, a torsion spring is also provided at the position where the box cover 2 is hingedly connected to the base 1, so that the box cover can be automatically flipped open relative to the base after the locking structure is unlocked.
