Description

Technical Field

[0001] The invention relates to the technical field of pulmonary function instruments, and in particular to a novel intelligent pulmonary function instrument. Background Art

[0002] The intelligent pulmonary function meter is an advanced medical device used to detect the human lung ventilation function. It combines traditional pulmonary function testing technology with modern intelligent technology, and can quickly and accurately measure multiple pulmonary function indicators, providing key data support for the diagnosis of lung diseases and evaluation of treatment effects.

[0003] It is mainly based on the principles of respiratory mechanics and gas flow detection. When the patient breathes into the mouth of the instrument, the sensor inside the instrument can detect the change of airflow. For example, the pressure difference between the two ends of the airway during breathing is measured by a differential pressure sensor, and then the gas flow is calculated according to the fluid mechanics formula; at the same time, combined with the time parameter, the flow is integrated to obtain the respiratory volume. After these measurement data are processed by intelligent algorithms, lung function indicators such as forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and peak expiratory flow (PEF) are obtained.

[0004] At present, patients need to replace the mouthpiece with a new one after using the pulmonary function meter. The replacement process is rather cumbersome. In addition, some patients with weak bite force, such as elderly patients, may not be able to fully wrap the mouthpiece after putting the mouthpiece in their mouth, and gaps are inevitable, which will affect the test results. At the same time, when patients use the pulmonary function meter, saliva and other secretions are cross-transmitted between patients, which may lead to cross-infection of bacteria. Therefore, the present device provides a new type of intelligent pulmonary function meter. Summary of the invention

[0005] The embodiment of the present invention provides a novel intelligent pulmonary function instrument to solve the above-mentioned technical problems.

[0011] Furthermore, the disinfection equipment includes a disinfection bottle body, a disinfection bottle head, a disinfection pipeline, a disinfection spray pipe and a pressing block. The side end of the intelligent pulmonary function instrument is provided with a slide groove, and the side end of the disinfection bottle head is slidably set in the slide groove. The disinfection bottle head is located at the bottom of the slide groove due to the influence of gravity. The disinfection bottle body and the disinfection bottle head are threadedly connected, and the disinfection bottle body and the disinfection bottle head are connected by a pipeline. A spray head is provided on the disinfection bottle head. The pressing block is set at the bottom of the slide groove and is located directly above the disinfection bottle head. One end of the disinfection pipeline is connected to the spray head and the other end passes through the auxiliary device and is located inside it. The disinfection spray pipe is located inside the auxiliary device, and the disinfection spray pipe is connected to the other end of the disinfection pipeline. A plurality of spray holes are provided on the disinfection spray pipe.

[0012] Furthermore, the plurality of spray holes are all oriented toward the corresponding oral mouth, and the plurality of spray holes are evenly distributed around the disinfection spray pipe. The disinfection pipeline is a hose, and a sealing ring is provided at the position where the disinfection pipeline passes through the auxiliary device.

[0013] Furthermore, the intelligent pulmonary function meter has a language prompt function, which can broadcast the countdown of the measurement time, prompt the person to start blowing, and broadcast the end of the measurement. It can automatically record the detailed data of each examination, including the patient's basic information, the measurement results of various pulmonary function indicators and the examination time, and transfer the data to the internal memory or external storage device. The intelligent pulmonary function meter can automatically generate a detailed examination report based on the measurement data.

[0014] Furthermore, the exteriors of several of the oral spouts are provided with anti-slip grooves.

[0015] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, when the patient's mouth is placed on the mouthpiece for exhalation detection, because the mouthpiece is mounted on the auxiliary device, it is easy for the mouthpiece to separate from the auxiliary device, and the resulting gap will affect the detection result and the normal detection process. A torsion spring is provided at the rotation connection between the adjusting rod and the adjusting shaft, and the force of the torsion spring is a counterclockwise force, that is, a force in the direction of the mouthpiece. Therefore, the pressing block can be pressed at the upper end of the mouthpiece required for the mouthpiece, thereby preventing the mouthpiece from separating from the auxiliary device, thereby further improving the detection accuracy of the device. At the same time, through the two auxiliary frames and the two sides of the pressing block, the two ear straps can be better and more conveniently worn on the ears. Through the combination of the auxiliary wearing device and the adjustment device, the detection accuracy of the device is further improved.

[0017] Secondly, some patients with weak bite force, for example, elderly patients, may not be able to fully wrap the mouthpiece after putting the mouthpiece in their mouth, and gaps are inevitable, which will affect the detection results. At this time, two ear straps can be put on the ears, and the way they are put on are the same as those of medical masks. Through the fixing method of the ear straps, after the patient puts the mouthpiece in their mouth, a tensile force will be generated on the mouthpiece toward the patient's mouth, so that the patient's mouth can wrap the mouthpiece to the greatest extent, ensuring that the mouthpiece remains stable in the patient's mouth and reducing gaps caused by the inability to completely wrap the mouth, thereby achieving the ability to accurately detect the patient's exhaled gas, improving the detection accuracy of the device, facilitating widespread use, and being relatively simple to wear and operate.

[0018] Thirdly, when the patient completes the pulmonary ventilation and respiratory function test through the device, the patient who has completed the test only needs to gently lift the pressing block and take off the mouthpiece used for the test, and then press the disinfection bottle body upward. After the disinfection bottle body is pressed upward, the disinfection bottle head will slide upward in the slide groove and contact the pressing block, so that the disinfection bottle body is squeezed, and the disinfectant water inside the disinfection bottle body flows from the disinfection pipeline into the disinfection spray pipe, and finally sprays and disinfects the inside of the mouthpiece and the inside of the auxiliary device through a number of spray holes. By repeatedly pressing the disinfection bottle body upward, the patient's exhaled gas inside the mouthpiece and the auxiliary device can be well disinfected, so that it can be continuously used for testing by the next patient, which can effectively prevent cross-transmission of secretions such as saliva between patients and cross-infection of bacteria, improve the accuracy and reliability of the test results, and help doctors make correct diagnoses.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] The embodiment of the present invention provides a novel intelligent pulmonary function instrument, comprising an intelligent pulmonary function instrument 1 for testing pulmonary ventilation and respiratory function to evaluate pulmonary function, a mouthpiece 2 for a patient to hold in the mouth for testing, an adjustment device 3 for pressing the mouthpiece 2, an auxiliary wearing device 4 for assisting the intelligent pulmonary function instrument 1 to be worn on the ear, and a disinfection device 5 for disinfecting the inside of the mouthpiece 2, wherein the mouthpiece 2 is arranged on the intelligent pulmonary function instrument 1 and is connected, the adjustment device 3 is arranged on the upper end of the mouthpiece 2, the wearing device is arranged on the adjustment device 3, the disinfection device 5 is arranged outside the intelligent pulmonary function instrument 1, and the disinfection spray head 56 of the disinfection device 5 is located inside the mouthpiece 2;

[0035] The device can be held by the patient and can be used to perform lung ventilation and respiratory function testing by blowing. During the testing process, the patient can accurately perform the blowing test for the required duration, and multiple people can continuously perform the lung ventilation and respiratory function testing. The device can be disinfected in real time without causing normal effects on the test results and without creating a risk of cross infection between patients.

[0036] When using the device, the patient should be instructed in detail on the correct way to hold the device in the mouth. For example, the patient should be instructed to gently wrap the mouthpiece 22 with his lips and hold it naturally like a straw to avoid excessive force or looseness. At the same time, the patient should be informed to keep the head and mouth as stable as possible during the test and reduce unnecessary movements. After the patient holds the mouthpiece 22 in the mouth, the medical staff should carefully check the position and fit of the mouthpiece 22. If any gap is found, the two ear straps 44 can be worn for auxiliary use.

[0037] The device can perform the exhalation detection operation by only wrapping the mouth with the mouthpiece 22, without sealing the nose, and the detection result will not be affected by the patient's nasal inhalation.

[0038] On the operation interface of the intelligent pulmonary function instrument 1, medical staff can select appropriate test items according to the specific conditions of the patients and the purpose of the test. For example, if it is a patient suspected of having lung disease during the initial examination, basic ventilation function tests such as vital capacity and forced vital capacity will usually be performed first; if it is a patient who has been diagnosed with asthma, a bronchial dilation test or a provocation test may also be required. According to the selected test items, the corresponding test parameters are set. For example, when performing forced vital capacity testing, the number of tests (usually 3 times) and the interval time between each test (usually 30-60 seconds) need to be set to ensure that accurate and reliable data are obtained;

[0039] When conducting a forced vital capacity test, the patient must take a deep breath and then exhale forcefully, quickly, and completely. The instrument will display the expiratory flow-volume curve in real time, and automatically calculate important parameters such as forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow after the test. During the entire test process, medical staff must closely observe the patient's breathing movements and the instrument's test data to ensure the smooth progress of the test.

[0040] The intelligent pulmonary function instrument 1 will automatically store the data of each test, and medical staff can view and analyze these data in the instrument's storage system or connected computer software. For example, by comparing the patient's pulmonary function test data at different times, the progression of the disease or the treatment effect can be observed. The intelligent pulmonary function instrument 1 can generate a detailed test report, including the patient's basic information, test items, the measured values ​​of various pulmonary function parameters, the comparison with normal reference values, and preliminary diagnostic suggestions, etc. Medical staff can make further diagnosis and treatment decisions based on these reports, and can also print out the reports and provide them to patients or other medical institutions.

[0041] The device is small in size, light in weight, and easy to carry, so users can perform lung function tests anytime and anywhere.

[0042] How to use this device:

[0043] Preparation: Make sure the device has been charged and calibrated as necessary, prepare several disposable mouthpieces 22 and other accessories, and connect several disposable mouthpieces 22 in a nested manner.

[0044] Patient preparation: Have the patient sit or stand upright and relax, keep breathing normal, explain the test procedure to the patient, and make sure he understands the importance and purpose of the test.

[0045] Connect and start the device: Connect the sensor component to the disposable mouthpiece 22, press the power button on the device to start the device, and you may see some menu options on the display.

[0046] Select test type: Select the appropriate test type according to your needs, such as spirometry, expiratory flow measurement, etc.

[0047] Conduct the test: Follow the instructions on the device display, such as taking a deep breath and then exhaling quickly and forcefully. The device will record and measure the patient's breathing parameters.

[0048] View results: After the test is completed, the device will display the corresponding test results, including the values ​​of various parameters.

[0049] Cleaning and storage: After use, disinfect and clean the equipment in time, remove and discard the disposable mouthpiece 22 as required, and expose the other mouthpiece 22 to the outside for continuous testing.

[0050] Preferably, the oral device 2 includes an auxiliary device 21 and an oral mouthpiece 22, and the oral devices 2 are all disposable medical products. The auxiliary device 21 is connected and arranged on the intelligent pulmonary function instrument 1, and a plurality of oral mouthpieces 22 are provided, and a plurality of the oral mouthpieces 22 are nested and the innermost oral mouthpiece 22 is sleeved on the outside of the auxiliary device 21. A plurality of the oral mouthpieces 22 include an oral portion 221 and a sleeve portion 222, and a plurality of the sleeve portions 222 are sleeved in layers, and a plurality of the oral portions 221 are also sleeved in layers, and a plurality of the oral mouthpieces 22 are provided with anti-slip patterns on the outside;

[0051] By providing anti-slip grooves on the outside of the mouthpiece 22, the friction between the lips and the mouthpiece 22 can be increased, making the mouthpiece 22 more stable in the mouth. For example, some hydrogel coatings can remain moist when contacting the oral mucosa, further improving the fitting effect, and also preventing the mouthpiece 22 from sliding in the mouth;

[0052] "Nesting" is commonly used in life and industrial design. It vividly describes the state in which an object, here the mouthpiece 22, is placed inside another identical or similar object. These cups are nested one inside another, like Russian dolls. This nesting method facilitates the storage and storage of cups and reduces space occupation.

[0053] Isolation effect: The disposable mouthpieces 22 are stored in a nested manner, which can effectively isolate dust, bacteria and other pollutants in the external environment. When they are nested together, the inner mouthpiece 22 is wrapped by the outer layer, reducing the chance of contact with the outside world. For example, in medical places such as hospitals or physical examination centers, this nesting method can ensure that the mouthpiece 22 remains relatively sterile before use, reducing the risk of cross-infection between patients. For some equipment that requires lung function testing, aerosol treatment and other operations, the use of nested disposable mouthpieces 22 can prevent pathogens from spreading between different patients. Respiratory infectious diseases such as influenza and tuberculosis can be prevented and controlled to a certain extent in this way;

[0054] Hygiene protection during use: The nested design allows the mouthpiece 22 to be better kept hygienic during use. Medical staff can easily remove the outermost mouthpiece 22 for use by the patient without contaminating the remaining mouthpieces 22. Moreover, even if the nested mouthpieces 22 are accidentally touched during operation, the inner mouthpiece 22 can still be kept relatively clean due to the multi-layer isolation. This is very important for some medical operations with extremely high hygiene requirements, such as the mouthpiece 22 used in oral examination equipment or respiratory therapy equipment;

[0055] The disposable buccal spouts 22 can be arranged compactly by nesting, which greatly saves storage space. In the storage room of a medical institution or the accessory box of an equipment, this compact storage method can store more buccal spouts 22 in a limited space. For example, compared with placing the buccal spouts 22 in a scattered manner, the nested buccal spouts 22 may only occupy one-third or even less of the original space, which facilitates inventory management and transportation. For some places that need to reserve a large number of buccal spouts 22, such as large hospitals, mobile medical stations, etc., the space-saving effect is particularly obvious;

[0056] Easy to sort and count; the nested buccal spouts 22 are more neat and orderly when stored, which is convenient for staff to sort and count. Medical staff can easily determine the number of buccal spouts 22 by counting the number of nested layers or observing the stacking situation. This improves work efficiency and reduces the possibility of errors for inventory management and material statistics. Moreover, when new buccal spouts 22 are needed, the new batch can be easily nested on the original buccal spouts 22 pile to maintain the neatness of storage;

[0057] Prevent damage: The nested disposable mouthpieces 22 can protect each other during storage and transportation. The outer mouthpiece 22 can be used as a new type of intelligent pulmonary function meter buffer layer to protect the inner mouthpiece 22 from external squeezing and collision. For example, during transportation, even if the packaging box is subjected to a certain degree of bumps or collisions, the nested mouthpieces 22 are not prone to damage such as cracking and deformation due to the multiple layers of protection. This is very important for ensuring the quality and integrity of the mouthpiece 22, because a damaged mouthpiece 22 may affect the use effect and even pose a potential risk to the patient's health.

[0058] Maintaining stable shape and performance: Through nesting, the mouthpiece 22 can maintain the stability of its shape and performance. They will not be deformed due to long-term storage in the nested state, ensuring that they can properly fit the patient's mouth when used. Moreover, this stable storage method also helps to maintain the physical properties of the mouthpiece 22, such as the elasticity of the material, so that the patient can have a comfortable experience when using it, while also ensuring the sealing performance of the connection between the medical device and the mouthpiece 22.

[0059] Preferably, the adjustment device 3 comprises an adjustment frame 31, an adjustment shaft 32, an adjustment rod 33 and a pressing block 34. Two adjustment frames 31 are provided, and the two adjustment frames 31 are symmetrically arranged at the upper end of the placement device. The adjustment shaft 32 is arranged between the two adjustment frames 31. The adjustment rod 33 is sleeved on the adjustment shaft 32 and is rotatably connected. A torsion spring is provided at the rotational connection between the adjustment rod 33 and the adjustment shaft 32. The pressing block 34 is arranged at the end of the adjustment rod 33 and abuts against the upper end of the corresponding oral mouthpiece 22.

[0060] Preferably, the auxiliary wearing device 4 comprises an auxiliary frame 41, an auxiliary knob 42, an auxiliary wearing rope 43 and an ear wearing strap 44, the auxiliary frame 41 is provided with two, the two auxiliary frames 41 are symmetrically arranged on both sides of the pressing block 34, the two auxiliary frames 41 are located on both sides of the corresponding sleeve 222, the auxiliary wearing rope 43 is provided with two, the two auxiliary wearing ropes 43 are symmetrically arranged, the auxiliary knob 42 is provided with four, the outer sides of the two auxiliary frames 41 are provided with threaded holes threadedly connected to the corresponding placement knobs, both ends of the two auxiliary wearing ropes 43 are wrapped around the corresponding auxiliary knobs 42 and are fixed to the corresponding auxiliary frames 41 by the corresponding auxiliary knobs 42, the ear wearing straps 44 are provided with two, the two ear wearing straps 44 are arranged in the middle of the corresponding auxiliary wearing ropes 43, and the inner sides of the two ear wearing straps 44 are provided with a flexible layer;

[0061] By rotating the corresponding auxiliary knob 42 , the corresponding auxiliary wearing cord 43 can be removed and replaced.

[0062] When the patient puts his mouth in the mouthpiece 22 for exhalation detection, because the mouthpiece 22 is mounted on the auxiliary device 21, it is easy to cause the mouthpiece 22 to separate from the auxiliary device 21, and the gap will affect the detection result and the normal detection process. A torsion spring is provided at the rotation connection between the adjusting rod 33 and the adjusting shaft 32, and the force of the torsion spring is a counterclockwise force, that is, a force in the direction of the mouthpiece 22. Therefore, the pressing block 34 can be pressed at the upper end position of the mouthpiece 22 required for the mouth, so as to prevent the mouthpiece 22 from separating from the auxiliary device 21, thereby further improving the detection accuracy of the device. At the same time, through the two auxiliary frames 41 and the two sides of the pressing block 34, the two ear wearing straps 44 can be better and more conveniently worn at the ear position. Through the combination of the auxiliary wearing device 4 and the adjustment device 3, the detection accuracy of the device is further improved.

[0063] Preferably, the disinfection device 5 includes a disinfection bottle body 51, a disinfection bottle head 52, a disinfection pipeline 53, a disinfection spray pipe 54 and a pressing block 55. The side end of the intelligent pulmonary function instrument 1 is provided with a slide groove 11, and the side end of the disinfection bottle head 52 is slidably arranged in the slide groove 11. The disinfection bottle head 52 is located at the bottom of the slide groove 11 due to the influence of gravity. The disinfection bottle body 51 and the disinfection bottle head 52 are threadedly connected. The disinfection bottle body 51 and the disinfection bottle head 52 are connected by a pipeline. A spray head 56 is provided on the disinfection bottle head 52. The pressing block 55 is arranged at the bottom of the slide groove 11 and is located at the disinfection Right above the bottle head 52, one end of the disinfection pipeline 53 is connected to the spray head 56 and the other end passes through the auxiliary device 21 and is located inside it. The disinfection spray pipe 54 is located inside the auxiliary device 21. The disinfection spray pipe 54 is connected to the other end of the disinfection pipeline 53. The disinfection spray pipe 54 is provided with a plurality of spray holes 57, and the plurality of spray holes 57 are all oriented toward the corresponding oral mouthpiece 22. The plurality of spray holes 57 are evenly distributed around the disinfection spray pipe 54. The disinfection pipeline 53 is a hose, and a sealing ring is provided at the position where the disinfection pipeline 53 passes through the auxiliary device 21;

[0064] After the disinfectant in the disinfection bottle 51 is used up, the disinfection bottle 51 is rotated and removed, and the disinfectant is filled in and then the disinfection bottle 51 is connected and reused;

[0065] When the patient completes the pulmonary ventilation and respiratory function test through the device, the patient who has completed the test only needs to gently lift the pressing block 34 and remove the mouthpiece 22 used for the test, and then press the disinfection bottle body 51 upward. After the disinfection bottle body 51 is pressed upward, the disinfection bottle head 52 will slide upward in the slide groove 11 and contact with the pressing block 55, so that the disinfection bottle body 51 is squeezed, and the disinfection water inside the disinfection bottle body 51 flows from the disinfection pipeline 53 into the disinfection spray pipe 54, and finally sprays and disinfects the inside of the mouthpiece 22 and the inside of the auxiliary device 21 through a plurality of spray holes 57. By repeatedly pressing the disinfection bottle body 51 upward, the patient's exhaled gas inside the mouthpiece 22 and the auxiliary device 21 can be well disinfected, so that it can be continuously used for the next patient for testing, which can effectively prevent the cross-transmission of secretions such as saliva between patients and other cross-infection of bacteria, because many infectious diseases can be transmitted through secretions such as saliva, such as influenza virus, tuberculosis bacteria, etc. Preventing cross-transmission of saliva can effectively cut off the transmission routes of these infectious diseases. For example, during the peak influenza season, if medical equipment such as spirometers can effectively avoid cross-infection of saliva, the risk of influenza transmission in hospitals and other testing sites can be reduced. Tuberculosis is a chronic infectious disease that is transmitted through droplets (containing a large amount of saliva) by a new type of intelligent spirometer. Strictly preventing cross-transmission of saliva is particularly important for controlling the spread of tuberculosis. Therefore, this device provides continuous exhalation intelligent testing for multiple patients while avoiding cross-transmission of saliva and other secretions between patients and cross-infection of bacteria. At the same time, cross-infection of saliva and other secretions may interfere with the test results. For example, if a patient's saliva contains foreign pathogens or inflammatory substances, these substances may affect the composition of the exhaled gas of the next patient during the test, thereby affecting the spirometer's judgment of the patient's true lung function status. Preventing cross-infection can ensure the purity of each patient's test sample, improve the accuracy and reliability of the test results, and help doctors make correct diagnoses.

[0066] Preferably, the intelligent pulmonary function instrument 1 has a language prompt function, which can broadcast the countdown of the measurement time, prompt the personnel to start blowing, broadcast the end of the measurement, and automatically record the detailed data of each examination, including the patient's basic information, the measurement results of various pulmonary function indicators and the examination time, and transfer the data to the internal memory or external storage device. The intelligent pulmonary function instrument 1 can automatically generate a detailed examination report based on the measurement data;

[0067] When using the device to perform pulmonary ventilation and respiratory function testing, the intelligent pulmonary function instrument 1 can first be set to a normal breathing detection range duration, and after pressing the start button on the intelligent pulmonary function instrument 1, a voice broadcast will be given first [In ten seconds] to start the test, and the intelligent pulmonary function instrument 1 will count down nineteen eighty seven six five four three two one. This time period allows the patient to take a calm breath 2-3 times first, and then take a deep breath to the total lung volume. At this time, the formal test begins, the patient holds the mouthpiece 22 in the mouth, and then exhales forcefully, quickly and completely. The exhalation time is required to be as short as possible, usually within 6 seconds, and the exhalation process is continued as long as possible until no more gas can be exhaled. After the test is completed, the intelligent pulmonary function instrument 1 will inform the personnel of the end of the test through voice broadcast. During this process, the intelligent pulmonary function instrument 1 will record the expiratory flow-volume curve. The forced expiratory volume in the first second (FEV1) is a key indicator. Under normal circumstances, the FEV1 / FVC ratio is generally greater than 70%. In order to ensure the accuracy of the test results, each test item generally needs to be repeated 2-3 times, and the interval between each test is 30-60 seconds. Let the patient take a short rest and restore normal breathing before the next test. Take the best value or average value as the final test result. The specific value selection method depends on different test purposes and instrument requirements;

[0068] Some patients with weak bite force, for example, elderly patients, may not be able to fully wrap the mouthpiece 22 after putting it in their mouth, and gaps are inevitable, which will affect the detection results. At this time, two ear straps 44 can be put on the ears, and the way of putting on is the same as that of medical masks. Through the fixing method of the ear straps 44, after the patient puts the mouthpiece 22 in their mouth, the mouthpiece 22 will generate a tensile force toward the patient's oral cavity, so that the patient's mouth can wrap the mouthpiece 22 to the greatest extent, ensuring that the mouthpiece 22 remains stable in the patient's mouth, reducing the gap caused by the inability to fully wrap the mouth, thereby achieving the accuracy of detecting the patient's exhaled gas, improving the detection accuracy of the device, facilitating widespread use, and the wearing method and operation are relatively simple.

[0069] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
