Description

Respiration collector

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a respiratory collector.

Background

Respiratory motion is always a non-negligible factor in the radiotherapy process of chest and abdomen tumors, and the position of the tumors in the radiotherapy is obviously affected. In clinical work, to prevent target region off-target due to respiratory motion, the radiologist enlarges the target region PTV (planning target region) to prevent off-target, which inevitably increases the burden of normal tissue surrounding the tumor and increases the risk of corresponding normal tissue complications. The reasonable application of the respiratory control technology can obviously reduce the movement amplitude of tumors and reduce the limit value of the expansion required by respiratory movement when the target area is sketched, thereby reducing the volume of PTV, and being particularly important for chest and abdomen tumors such as breast, lung and liver, especially for lung cancer patients.

In order to achieve accurate treatment of chest tumors, errors caused by respiratory motion are eliminated, and a subject is required to perform deep inhalation breath-hold under abdominal respiration in a matched manner. Devices (breathing gating for short) for acquiring and displaying the breathing amplitude curve of the patient in real time based on the infrared detection technology are arranged in the CT room and the treatment room. The device is used to determine if the patient's deep inhalation breath-hold is within an acceptable range. The specific treatment process is as follows: firstly, a patient acquires a breathing curve of the patient on a CT machine room through a breathing gating technology, and when the breathing curve of the patient is in a proper interval, breath is shielded, and CT data are acquired. And taking the CT image of the patient in the breath-hold interval as a judgment basis of the treatment target area. Thereafter, during the treatment phase, radiation therapy is delivered while the patient is held in the same interval as the CT hold. Thus, the accuracy of the target area is ensured. However, due to differences in physical conditions of patients, not every patient can hold his breath for CT scanning, and often the patient cannot hold his breath during CT scanning. Meanwhile, many patients cannot adopt abdominal respiration, so that the respiration gate is convenient for collecting the respiration curve of the patient. It often happens that the patient makes CT, but the breathing condition does not meet the treatment condition, which causes two disadvantages: first, the occupancy rate is a CT resource with originally tense resources; second, patients eat radiation (CT scanning has low-dose radiation generation and has a certain degree of damage to human bodies). Meanwhile, because the body surface tracking technology or the infrared detection technology adopted by the existing respiratory gating technology is very expensive, the probability that equipment with the respiratory gating technology is configured in multiple ways to perform respiratory training on a patient in advance is low in other scenes, and therefore a respiratory training device is needed to perform respiratory training on the patient.

The breath collector is an important structure of the breath training device and is used for collecting the breath signals of a patient. Chinese patent application publication No. CN 210077681U discloses a measuring instrument for detecting breath-hold amplitude of a patient in real time, comprising a display device and a breath-hold detecting device; the breath-hold detection equipment comprises a shell, wherein a digital air pressure sensor and a circuit board are arranged in the shell, and a processor module, a communication module and a power module are arranged on the circuit board; the instrument also comprises a pre-inflated breathing chest strap, one end of the pre-inflated breathing chest strap is fixed on the housing of the breath-hold detection device and is connected with the digital air pressure sensor through an air pipeline, and the other end of the pre-inflated breathing chest strap is detachably and fixedly connected to the housing of the breath-hold detection device; and a communication module is arranged in the shell of the display device and is used for realizing signal transmission with the breath-hold detection device. When the measuring instrument is used, the pre-inflated respiratory chest belt is inflated, and then the pre-inflated respiratory chest belt is fixed with the detachable end around the patient and tightly attached to the trunk below the last rib. It can be seen that such measuring instruments have the problem of complex operation.

The technical scheme of the utility model is further specifically described by the following specific embodiments with reference to the accompanying drawings:

example 1

As shown in fig. 1, a respiration collector includes a mounting frame 1 and a collection unit 2, the mounting frame 1 includes two support arms 11, two connection arms 12 and a mounting seat 13, the two support arms 11 are relatively arranged, one ends of the two support arms 11 are respectively connected with one ends of the two connection arms 12 in a rotating way, the other ends of the two connection arms 12 are respectively connected with the mounting seat 13 in a rotating way, and the collection unit 2 is mounted on the mounting seat 13 and is used for collecting abdomen fluctuation height change data of a user under a respiration state. In this embodiment, when in use, a user lies on a bed, the free ends of the two support arms 11 are placed on the bed and located on two sides of the user's body, and since one end of the connecting arm 12 is connected with one end of the support arm 11, the other end of the connecting arm 12 is connected with the mounting seat 13, and the mounting seat 13 is provided with the acquisition unit 2, so that the acquisition unit 2 can be located above the abdomen of the user, and the abdomen fluctuation height variation data (i.e. the distance variation between the acquisition unit 2 and the abdomen acquisition point of the user) of the user during breathing is acquired by using the acquisition unit 2, and the abdomen fluctuation height variation data reflects the breathing process of the user to a certain extent. Because the both ends of linking arm 12 are connected with support arm 11, mount pad 13 rotation respectively to can adjust the span between two support arms 11 and install the height of collection unit 2 on mount pad 13, in order to adapt to different user's physique. It should be noted that, for a user with a fatter body, the span between the two support arms 11 is increased, so that the two support arms 11 can be located on two sides of the body of the user (as shown in fig. 2), and the height of the mounting base 13 is increased, so that the height of the acquisition unit 2 mounted on the mounting base 13 is increased. For a user of a thin body type, the span between the two support arms 11 is reduced and the two support arms 11 can be positioned on two sides of the body of the user (as shown in fig. 3), and the height of the mounting base 13 is reduced, so that the height of the acquisition unit 2 mounted on the mounting base 13 is reduced. In adjusting the span between the two support arms 11 and the height of the mounting 13, this can be achieved by adjusting the angle between the support arms 11 and the connecting arm 12. It should be noted that, after the collecting unit 2 collects the abdomen fluctuation height variation data when the user breathes, the respiratory condition of the patient is indirectly detected through the abdomen fluctuation height variation data, the height variation data can be transmitted to a corresponding respiratory trainer through a transmitting module, and the respiratory trainer is provided with intelligent equipment of an APP special for respiratory training, and can operate and set various parameters of respiratory training.

As shown in fig. 6, the length of the connection arm 12 is equal to or longer than the length of the support arm 11 so that the support arm 11 is housed inside the connection arm 12. Because the both ends of linking arm 12 rotate with support arm 11, mount pad 13 respectively, and the length of linking arm 12 is greater than or equal to the length of support arm 11, when the breath collector does not need to use, can rotate two support arms 11 respectively to the inboard of linking arm 12 rather than linking to each other for support arm 11 is the approximately laminating state with linking arm 12 rather than linking to each other, and two support arms 11 are approximately parallel state with two linking arm 12, reduce the volume of whole breath collector as far as possible, in order to carry the breath collector.

As shown in fig. 1 to 8, the supporting arm 11 and the connecting arm 12 are each in a plate-like structure, so that the supporting arm 11 and the connecting arm 12 can be more easily accommodated inside the connecting arm 12 and kept in contact with the connecting arm 12 when accommodated. Because the supporting arm 11 and the connecting arm 12 adopt a plate-shaped structure, and the two supporting arms 11 are oppositely arranged, when one end of the supporting arm 11 is contacted with the bed surface, the stability of the respiration collector can be ensured.

As shown in fig. 7, the end of the support arm 11 remote from the connection arm 12 is formed with an arc-shaped contact portion 14. In this embodiment, the arc-shaped contact portion 14 can ensure that the support arm 11 and the bed surface maintain a certain contact area when the respiration collector is in use, so that the respiration collector can stably stand on the bed surface in the use process.

As shown in fig. 1, the acquisition unit 2 is one of a pull rod type resistance sensor 29, an infrared sensor, an ultrasonic sensor, an angle sensor, and a gyroscope. In this embodiment, the pull rod type resistance sensor 29, the infrared sensor, the ultrasonic sensor, the angle sensor, and the gyroscope all have the function of measuring the distance, and the acquisition unit 2 can acquire the distance change between the acquisition unit 2 and the acquisition point, that is, the height change data between the acquisition unit 2 and the abdomen of the user by adopting any of the above. It should be noted that, the pull rod type resistance sensor 29 is a contact type collection, the telescopic probe of the pull rod type resistance sensor 29 is in contact with the bellyband of the patient, the bellyband can be up and down fluctuated along with the respiratory motion after the patient adopts the bellyband respiration, so that the telescopic motion of the telescopic probe is driven to drive the sliding rheostat in the pull rod type resistance sensor 29, the current passing through the sliding rheostat generates corresponding linear change, finally, the pull rod type sensor can output an analog current signal to the controller of the respiration collector, and the controller processes the current signal and then transmits the current signal to the respiration trainer through the transmission module. The infrared sensor, the ultrasonic sensor, the angle sensor and the gyroscope are non-contact sensors, and the non-contact sensors can acquire distance data between the acquisition unit 2 and an acquired point (the abdomen position of a user) and then transmit the distance data to the respiration trainer through the transmission module.

The device also comprises a sending module, wherein the sending module is electrically connected with the acquisition unit 2. In this embodiment, the sending module may be a bluetooth module, or may be a unit capable of implementing a data transfer function, such as a WIFI module, where the sending module transfers the data collected by the collecting unit 2 to the respiratory trainer.

Example 2

The difference from embodiment 1 is that, as shown in fig. 1, 6 to 8, the connection arm 12 is formed with a first boss 15 at the connection with the support arm 11, and the first boss 15 is provided with a first connection hole 16 in the direction of the rotation center line; the support arm 11 is provided with a first notch 17 at the joint with the connecting arm 12, the two sides of the support arm 11, which are positioned at the first notch 17, are respectively provided with a first connecting lug 18, the first connecting lug 18 is provided with a second connecting hole 19 along the direction of the rotation center line, the first boss 15 is arranged in the first notch 17, and the first connecting hole 16 and the second connecting hole 19 are provided with a first fastener 20. In the present embodiment, since the first boss 15 is installed in the first gap 17 between the two first connection lugs 18 and then connected in the first connection hole 16 and the second connection hole 19 by the first fastener 20, the support arms 11 can be rotated about the first fastener 20 with respect to the connection arms 12, thereby adjusting the span before the two support arms 11. The first fastener 20 may be a pin, a connecting bolt, or the like. In this embodiment, the connection arm 12 and the support arm 11 are connected by adopting such a connection structure, so that the breath collector is approximately in a symmetrical structure, which is beneficial to balance of the breath collector, and avoids the problem that the breath collector falls down in the working process.

Wherein, the two opposite sides of the first boss 15 to the first connecting lug 18 are provided with first damping fins 21, and the first damping fins 21 contact with the inner side of the first connecting lug 18. In the present embodiment, since the first damping sheet 21 is in contact with the inner side surface of the first connection lug 18, the resistance when the support arm 11 and the connection arm 12 relatively rotate can be increased, and the rigidity of the whole breath collector can be ensured. It should be noted that, the first damping fin 21 forms a friction force on the first connection lug 18, and in order to achieve the relative rotation between the support arm 11 and the connection arm 12, it is generally necessary to apply a torque greater than or equal to 1n·m to the support arm 11 to rotate the support arm 11 relative to the connection arm 12. And when no external force acts on the connecting arm 12 and the supporting arm 11, the angle between the connecting arm 12 and the supporting arm 11 can be maintained, thereby ensuring the rigidity of the breath collector.

Example 3

The difference from embodiment 1 is that, as shown in fig. 1, 8 and 9, the mounting seat 13 is formed with a second boss 22 at the connection with the connection arm 12, and a third connection hole 23 along the rotation center line direction is provided on the second boss 22; the connecting arm 12 is provided with a second notch 24 at the joint with the mounting seat 13, second connecting lugs 25 are formed on two sides of the connecting arm 12, which are positioned on the second notch 24, fourth connecting holes 26 along the direction of the rotation center line are formed in the second connecting lugs 25, the second boss 22 is arranged in the second notch 24, and second fasteners 27 are arranged in the third connecting holes 23 and the fourth connecting holes 26. In this embodiment, since the second boss 22 is installed in the second notch 24 between the two second connection lugs 25 and then connected in the third connection hole 23 and the fourth connection hole 26 by the second fastener 27, the connection arm 12 can be rotated about the second fastener 27 with respect to the mounting base 13, thereby adjusting the height of the mounting base 13. The second fastener 27 may be a pin, a connecting bolt, or the like. In this embodiment, the connecting arm 12 is connected with the mounting base 13 by adopting the connecting structure, so that the breath collector is approximately in a symmetrical structure, which is beneficial to the balance of the breath collector and avoids the problem that the breath collector falls down in the working process. The second boss 22 is provided with second damping fins 28 on two opposite sides of the second connecting lug 25, and the second damping fins 28 are in contact with the inner side of the second connecting lug 25. The second damping fin 28 contacts with the inner side surface of the second connecting lug 25, so that the resistance of the mounting seat 13 and the connecting arm 12 during relative rotation can be increased, and the integral rigidity of the breath collector is ensured.
