Problems solved by technology

However, this method has many shortcomings
First, ice analgesia and laser irradiation cannot be performed at the same time. Ice analgesia often blocks the area irradiated by the laser, making it impossible for doctors to judge the effect of the current irradiation; second, ice melts into water droplets into the patient's mouth during the cooling process , not only makes the patient feel very uncomfortable (even flows down the mouth), but also the increased liquid in the mouth is not conducive to the doctor's operation

Embodiment 1

[0023] Such as figure 1 As shown in -a, a cooling and analgesic device includes a transparent plastic container, the plastic container is composed of a container body 1, a container cover (not shown), a handle 2 and a waterproof plug 4, and the container body and the container cover are threaded The handle is located on one side of the main body of the container. There are two refrigerant liquid passages 3 directly connected to the terminal solution pool inside the handle. The waterproof plug is used in conjunction with the refrigerant liquid passage to plug the refrigerant liquid passage. Keep the refrigerant liquid stored in the main body of the container sealed in the container, and store the container filled with refrigerant liquid in the refrigerator. After taking it out, cooling and analgesia can still be completed. After injecting physiological saline, cover the waterproof plug and place it in the In the refrigerator, when the inside of the container is frozen into ice ...

Embodiment 2

[0025] Such as figure 1 As shown in -b, a cooling and analgesic device includes a transparent plastic container and / or a cooling circulation system. The plastic container is composed of a container body 1, a container cover (not shown), a handle 2, a waterproof plug and a water-cooling interface 5 , the container body is threadedly connected to the container cover, the handle is located on one side of the container body, and the inside of the handle is provided with two refrigerant liquid passages 3 for directly connecting the terminal solution pool, the water cooling interface is a cylindrical structure, the water cooling The interface is arranged at the end of the cooling liquid channel, and the diameter of the waterproof plug is the same as the inner diameter of the water-cooling interface. The waterproof plug is used in conjunction with the cooling liquid channel to plug the cooling liquid channel so that the main body of the container The refrigerant liquid stored inside ...

Abstract

The invention provides a cooling and analgesic device, which comprises a transparent plastic container, the plastic container is composed of a container body, a container cover, a handle and a waterproof plug, the container body is screwed to the container cover, and the handle is located on the container body On one side, the handle is provided with two refrigerant liquid passages directly connected to the terminal solution pool. The waterproof plug is used in conjunction with the refrigerant liquid passage to plug the refrigerant liquid passage. The terminal solution pool is a container The concentric ring space in the main body is used to store cooling liquid or ice cubes, and can also include a cooling circulation system for reducing and alleviating thermal damage in dental laser treatment.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a cooling analgesic device. Background technique [0002] In recent years, with the development of laser technology, high-power pulsed lasers have been increasingly used in the clinical surgical treatment of stomatology-related diseases. However, in clinical practice, the irradiation dose of these lasers on corresponding biological tissues is only controlled by the actual experience of clinicians. This kind of control that only rests on perceptual knowledge is often inaccurate, and medical accidents caused by thermal injury will follow. At present, in the clinical practice of stomatology, doctors often use tweezers to clamp ice cubes to cool down the irradiated area and analgesia, and reduce potential thermal damage. However, this approach has many shortcomings. First, ice analgesia and laser irradiation cannot be performed at the same time. Ice analgesia often blocks the area irradiate...
