Description

Technical Field

[0001] The present invention specifically relates to a sputum specimen collection device. Background Art

[0002] In clinical medicine, sputum examination is one of the important bases for the diagnosis and treatment of respiratory diseases. Accurate collection of sputum specimens is crucial for disease diagnosis, treatment plan formulation, and treatment effect evaluation. Currently, the traditional method of collecting sputum specimens is usually for patients to directly spit sputum into ordinary specimen containers. However, most sputum will be mixed with a large amount of saliva, which will cause deviations in test results. Therefore, a sputum collection device is needed to filter saliva to improve the reliability of test data.

[0003] For example, the Chinese patent with the publication number CN215894169U provides a sputum sampler for a laboratory, including a support frame. A filtering structure is provided on the support frame. The filtering structure includes a connection box. The connection box is placed on the support frame. A sampling tube is fixedly connected to the connection box. A filter screen is provided in the connection box. A limiting groove is provided on the filter screen. A limiting block is fixedly connected to the connection box. The limiting block can be engaged with the limiting groove; it can separate saliva and sputum pus, simply remove impurities in saliva, and facilitate inspection by inspectors.

[0004] However, most of the existing sputum specimen collection devices can only be used once. Sometimes, when multiple samples need to be taken from a single patient or samples need to be continuously taken from multiple patients, multiple devices need to be used, resulting in an increase in sampling costs. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention proposes a sputum specimen collection device to solve the technical problem that most of the existing sputum specimen collection devices can only be used once.

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0047] Embodiment:

[0048] As Figure 1 shown, the present invention provides a sputum specimen collection device, which includes a mounting frame 1. A fixedly installed grip 2 and a slidable handle 3 are provided at the bottom of the mounting frame 1, and a first elastic member 4 is arranged between the grip 2 and the handle 3. The device can be used by holding the grip 2 by hand, and the handle 3 can be held to compress the first elastic member 4, and the handle 3 can be controlled to reset under the action of the first elastic member 4 after the handle 3 is released.

[0049] As Figure 2 、 3 、6 shown, in this embodiment, a mounting disk 15 is rotatably arranged on the mounting frame 1 along its axis. A plurality of groups of mounting grooves 16 are circumferentially and uniformly arranged on the mounting disk 15. A collection component with a filtering function is detachably arranged in the mounting groove 16. The collection component includes a filtering disk 19. The filtering disk 19 is arranged in the mounting groove 16. A pick-up plate 20 is arranged on the filtering disk 19, and filtering holes are formed on the filtering disk 19. A shielding piece 22 is rotatably arranged at the bottom of the filtering disk 19 along its axis. After the shielding piece 22 rotates, it can shield the filtering holes. A dial 23 is arranged on the shielding piece 22, and a through groove 21 is formed on the filtering disk 19. The dial 23 is slidably arranged in the through groove 21.

[0050] The patient can spit sputum into the filtering disk 19. In the initial state, the through holes of the shielding piece 22 are aligned with the filtering holes formed on the filtering disk 19, so that the entire collection component can filter the sputum. A receiving component is arranged on the mounting frame 1, and the receiving component is located below one group of the collection components to collect the filtered saliva. The receiving component includes a connecting pipe 5 arranged on the mounting frame 1 and located below one group of the filtering disks 19. A collection bottle 6 is screwed on the connecting pipe 5. The filtered saliva enters the collection bottle 6. The saliva can be collected for a long time through a single collection bottle, and there is no need to frequently replace the collection bottle 6.

[0051] As Figure 3 、 7 shown, in this embodiment, a driving mechanism connected to the mounting disk 15 is arranged on the handle 3. Through the driving mechanism, the single grip of the handle 3 is converted into driving the mounting disk 15 to rotate a specified angle in one direction. The driving mechanism includes a driving disk 9 rotatably arranged on the mounting frame 1 along its axis. A transmission component connected to the mounting disk 15 is arranged on the driving disk 9. Through the transmission component, the single rotation of the driving disk 9 is converted into driving the mounting disk 15 to rotate a specified angle. The transmission component includes a first synchronous pulley 14 arranged on the driving disk 9 and a second synchronous pulley 17 arranged on the mounting disk 15. The second synchronous pulley 17 is connected to the first synchronous pulley 14 through a synchronous belt 18.

[0052] During a single rotation of the drive disk 9, the first synchronous pulley 14 is driven to rotate. During the rotation of the first synchronous pulley 14, the second synchronous pulley 17 is driven to rotate through the synchronous belt 18, thereby controlling the rotation of the mounting disk 15. And since the circumference of the first synchronous pulley 14 is equal to the circumference of the second synchronous pulley 17 multiplied by the number of retention components, when the drive disk 9 rotates one circle, a set of unused retention components on the mounting disk 15 can be controlled to move directly above the collection bottle 6, thus quickly realizing multiple samplings and separations.

[0053] As Figure 3 , 7 shown, in this embodiment, a control component connected to the handle 3 is provided on the mounting frame 1. By the control component, the single reciprocating sliding of the handle 3 is converted into controlling the drive disk 9 to rotate one circle. The control component includes a connecting seat 10 eccentrically arranged at the bottom of the drive disk 9. A driving column 12 that can slide along its axis is arranged in the connecting seat 10. A second elastic member 11 is arranged between the driving column 12 and the connecting seat 10. A driving rod 13 is hinged on the connecting seat 10. One end of the driving rod 13 is hinged to the handle 3. Two sets of arc-shaped tracks 7 symmetrically arranged along the axis center of the drive disk 9 are provided on the mounting frame 1. The heights of the two ends of the arc-shaped track 7 are different. The two ends of the two sets of arc-shaped tracks 7 are connected end to end through inclined surfaces 8. The end of the driving column 12 abuts against the arc-shaped track 7.

[0054] During the process of holding and moving the handle 3, the drive disk 9 is driven to rotate through the driving rod 13. At the same time, the driving column 12 slides in the arc-shaped track 7. During the sliding process of the driving column 12, the drive disk 9 is guided, and under the action of the second elastic member 11, the end of the driving column 12 always abuts against the arc-shaped track 7. And through the setting of the inclined surface 8, when the driving rod 13, the center of the drive disk 9, and the handle 3 are on the same straight line, the driving column 12 is unidirectionally guided to prevent the drive disk 9 from reversing.

[0055] As Figure 2 , 3 , 5 shown, in this embodiment, a detachable receiving hopper 24 is further provided on the mounting frame 1. The top of the receiving hopper 24 is flared. The bottom of the receiving hopper 24 is on the same axis as the receiving component and one of the retention components. The patient can spit phlegm into the receiving hopper 24. The receiving hopper 24 guides the phlegm to prevent the phlegm from splashing to other places, improving the convenience during specimen sampling.

[0056] As Figures 2 to 5As shown, in this embodiment, a locking component connected to the handle 3 and the receiving hopper 24 is provided on the mounting bracket 1 to lock the receiving hopper 24 when the handle 3 is released and lock the position of the receiving hopper 24 when the handle 3 is [operated]. The locking component includes a mounting seat 30 provided on the mounting bracket 1. A locking bracket 26 is slidably provided on the mounting seat 30. A first convex block 27 is provided at one end of the locking bracket 26, and a locking block 32 is provided at the other end. An annular groove 25 is formed on the receiving hopper 24, and the locking block 32 is clamped in the annular groove 25. A second convex block 28 is provided on the handle 3, and a baffle 29 is provided on the locking bracket 26. A third elastic member 31 is provided between the baffle 29 and the mounting seat 30.

[0057] In the initial state, the locking block 32 is kept clamped in the annular groove 25 by the abutment of the third elastic member 31 to fix the position of the receiving hopper 24. When sampling multiple patients, when holding the handle 3 to control the unused sampling component to move below the receiving hopper 24, the first convex block 27 is pushed by the second convex block 28 to drive the locking bracket 26 to slide, so that the locking block 32 is disengaged from the annular groove 25, thereby releasing the fixation of the receiving hopper 24, and the receiving hopper 24 can be replaced to avoid the sputum residue of the previous patient affecting the subsequent test results.

[0058] Specific usage method and beneficial effects of the present invention:

[0059] When the device is in use, multiple groups of sampling components are placed in the installation groove 16. The patient spits phlegm onto the sampling components. The sampling components filter the phlegm, and the receiving components collect the filtered saliva to avoid excessive saliva affecting the subsequent phlegm test results. And after single sampling, by holding the handle 3 and converting the single hold of the handle 3 into driving the mounting disk 15 to rotate unidirectionally by a specified angle through the driving mechanism, the unused sampling components can be rotated to the sampling position, so that multiple samplings can be quickly performed on a single patient or multiple patients, effectively improving the sampling efficiency. At the same time, it is not necessary to consume a whole set of sampling devices every time of sampling, which greatly saves the medical cost.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments. Based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope claimed by the present invention.
