Problems solved by technology

[0004] After the traditional fixation device is fixed to the patient, it can only be unlocked by the medical staff, but the patient cannot unlock it by himself, which makes the patient prone to suffocation, aspiration pneumonia, and even death when symptoms such as nausea and vomiting occur. In order to solve this problem, some unlocking devices with unlocking function or fixing devices with unlocking function are disclosed in the prior art, such as Chinese patents CN 109125957A, CN109453471A, etc., so that patients can unlock themselves in emergency situations, improving safety However, there is usually the problem of poor versatility in the existing unlocking devices, because the existing unlocking devices all need a body with the correspond...

Embodiment 1

[0080] Such as Figure 4-Figure 15 As shown, this embodiment provides an unlocking device for a body frame, including several unlocking ends and flexible transmission parts, wherein the unlocking end includes a support part and an unlocking part, the unlocking part is arranged on the support part, and the flexible transmission part They are respectively connected to each supporting part for transmitting the unlocking power, and the unlocking parts are respectively used to move relative to the supporting part under the driving of the unlocking power, and squeeze the latch in the positioning hole through the action to drive the latch to unlock, thereby realizing Unlock function.

[0081] In this embodiment, the body frame board can be a body frame board commonly used in the prior art, as an example, such as Figure 1-Figure 3 As shown, there are nine positioning holes arranged on the body frame plate; usually only positioning hole 1 602, positioning hole 2 602, positioning hole...

Embodiment 2

[0097] The main difference between this embodiment 2 and the above embodiment 1 is that the structure of the flexible transmission part is different. In order to realize the synchronous unlocking function, in this embodiment, the flexible transmission part includes a main transmission part and several auxiliary transmission parts. The number is the same as the number of unlocking ends, and one end of each auxiliary transmission part is connected with each supporting part respectively, such as Figure 16 As shown, the other ends are respectively connected with the main transmission part, and the auxiliary transmission part is flexible, so that the position of each unlocking end can be placed flexibly. In this example, the unlocking terminals are connected in parallel to each other, which not only can realize synchronous unlocking, but also can match different types and sizes of frame plates to meet different unlocking requirements, etc., which can significantly improve the versa...

Embodiment 3

[0102]The main difference between this embodiment 3 and the above-mentioned embodiment 1 is that in the unlocking device provided by this embodiment, the structure of the unlocking part is different. Mobile pair, the other end is located in the keyhole, such as Figure 17 shown. When the pressure of the gas and / or liquid in the flow channel increases, the pressure drives the ejector rod to extend along the length direction of the lock hole, and makes one end of the ejector rod extend out of the lock hole, thereby realizing the unlocking function.

[0103] In order to prevent the ejector pin from falling off, such as Figure 17 As shown, further, a piston is provided at one end of the ejector rod, and the diameter of the ejector rod is smaller than the diameter of the piston, so that the unlocking part will not fall off from the support part. The piston is arranged in the flow channel and forms a moving pair with the flow channel, so that and / or move along the flow channel un...

Abstract

The invention relates to an unlocking device. The device comprises a plurality of unlocking ends and a flexible transmission part; the unlocking ends comprise supporting parts and unlocking parts, andthe unlocking parts are arranged on the supporting parts; the flexible transmission part is connected with the supporting parts and used for transmitting unlocking power; and the unlocking parts areused for acting relative to the supporting parts under driving of unlocking power and extruding bolts in positioning holes through the action so as to drive the bolts to perform unlocking. According to the unlocking device, the structure is compact, the size is small, the use is convenient and flexible, body frame plates can be unlocked, and the unlocking ends can be flexibly placed according to needs to correspond to the corresponding bolts and positioning holes so as to be matched with the body frame plates of different models and sizes and meet different unlocking requirements, so that theuniversality are significantly improved.

Description

technical field [0001] The invention relates to the technical field of chemotherapy equipment, in particular to an unlocking device for body frame boards. Background technique [0002] Radiation therapy (referred to as radiotherapy) is one of the main means of treating malignant tumors at present; domestic radiation therapy has entered the stage of precision treatment as a whole. During the process of precision radiotherapy, keeping the patient's position fixed is the key to precision treatment. [0003] In the prior art, a set of fixation devices are usually used to fix radiotherapy patients, and the fixation devices include: a thermoplastic film (or called a positioning film) and a body frame plate (or called a positioning plate), wherein the body frame plate It is a flat plate, a number of positioning holes are respectively arranged on the edge of the body frame plate, edge strips are respectively arranged on the edges on both sides of the thermoplastic film, and fixing h...
