[0002] Prostate cancer is one of the most common malignant tumors of the male reproductive system. Patients usually have no obvious symptoms in the early stage, but in the late stage, they may show symptoms such as hematuria, urinary incontinence, dysuria, and hematospermia. Bone metastasis may cause bone pain, pathological fractures, anemia, and spinal cord compression.

[0003] When performing non-invasive testing for prostate cancer, PSA testing can be used. The test results are obtained by testing the patient's blood with a testing device, i.e., a blood analyzer. However, when using existing testing devices, it is necessary to insert a probe used by the device to draw blood into a test tube containing blood for blood drawing and testing. When separating the test tube from the probe, misoperation is prone to occur, i.e., the test tube is moved outward before being completely separated from the probe, thereby pressing against the probe to bend and damage it.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a non-invasive detection device for prostate cancer. Figures 1 to 8 As shown, the detector 1 includes a detector 1, the top wall of which is provided with an electric push rod 2. The detector 1 is a blood cell analyzer in the prior art. A carrier plate 3 is fixedly installed at the bottom end of the electric push rod 2. The top wall of the detector 1 is provided with a mounting groove. A ball head sleeve 4 is fixedly installed in the mounting groove. A ball head 5 is provided inside the ball head sleeve 4. A probe 6 is provided in the middle of the ball head 5. A swab 7 is provided on the outer sleeve of the probe 6. The swab 7 is a swab used in conjunction with a blood cell analyzer in the prior art and can clean the probe 6. A limiting component for limiting the position of the swab 7 is provided on the outside of the carrier plate 3, and an anti-throwing component is provided on the outside of the swab 7 for preventing blood on the surface of the probe 6 from being thrown out when the probe 6 is reset.

[0018] When in use, the probe 6 is inserted into the test tube containing the patient's blood, and the blood is extracted and analyzed through the detector 1 and the probe 6, so as to determine whether the patient has prostate cancer. When the test tube is taken away, if the staff makes an error operation, that is, the probe 6 is not completely separated from the test tube, the test tube is moved outward. At this time, the test tube will press against the probe 6 to deflect it outward, thereby causing the ball head 5 and the swab 7 to deflect with it. Since the probe 6 can be adaptively deflected at this time, the probe 6 will not be pulled by the test tube and deformed. After the staff realizes the operation problem, they can move the test tube downward and then take the test tube away. After the test tube is separated from the probe 6, the limiting component drives the swab 7 to reset with the probe 6 and the ball head 5, and then the electric push rod 2 extends and carries the carrier plate 3, the limiting component, and the swab 7 down, so that the swab 7 cleans the blood on the probe 6. After the cleaning is completed, the electric push rod 2 is reset, and vice versa, the swab 7 can be reset, thereby completing the analysis of prostate cancer. During the whole process, when an operational error occurs and causes the test tube to pull the probe 6, the probe 6 can be avoided, thereby avoiding damaging the probe 6 and improving the operational fault tolerance. The anti-throw-out component can prevent the blood on its surface from being thrown out to the surface of the detector 1 when the probe 6 is reset.

[0019] like Figure 2 and Figure 3 As shown, the limiting assembly includes two pairs of side plates 8 arranged at the top and bottom of the carrier plate 3, and a slide groove is opened on the inner side of the side plate 8. A slide plate 9 is slidably installed in the slide groove. A limit ring 10 is fixedly installed between the two opposite slide plates 9. The limit ring 10 contacts the swab 7, and the side of the slide plate 9 away from the swab 7 is fixedly connected to the top wall of the slide groove through a spring 11.

[0020] When the probe 6 is deflected, the swab 7 moves accordingly, and the top and bottom ends of the swab 7 will respectively lift up the upper and lower limiting rings 10 to make it move away from the swab 7 with the slide plate 9, thereby compressing the spring 11 to deform it and generate a force. When the probe 6 loses the resistance of the test tube, the spring 11 releases the force to restore the slide plate 9 and the limiting ring 10, thereby squeezing the swab 7 to restore it with the probe 6 to a vertical state. When the carrier plate 3 descends, the side plate 8, the slide plate 9, and the limiting ring 10 are also descended, thereby bringing the swab 7 down. Conversely, when the carrier plate 3 rises, the swab 7 can be raised.

[0021] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the anti-throw-out component includes a rubber airbag 12 which is sleeved on the outside of the swab 7, a ring tube 24 is fixedly installed at the bottom of the rubber airbag 12, the ring tube 24 is threadedly connected to the outside of the swab 7, the ring tube 24 is connected to the rubber airbag 12, and a conduit 13 connected to the ring tube 24 is symmetrically fixedly installed on the outside of the ring tube 24, a flow equalizing component for making the airflow evenly blow to the surface of the probe 6 is provided at the bottom of the conduit 13, and an opening for the rubber airbag 12 to move is opened on the carrier plate 3.

[0022] At the moment when the swab 7 is reset, the swab 7 and the probe 6 will stop instantly. Due to inertia, the blood attached to the probe 6 will be thrown out. In order to avoid the above situation, when the probe 6 and the swab 7 are deflected, the rubber airbag 12 and the ring tube 24 will move accordingly. The rubber airbag 12 will conflict with the inner wall of the opening of the carrier plate 3, so that it is squeezed and the air inside it is squeezed out. At this time, the air is evenly blown to the surface of the probe 6 through the ring tube 24, the catheter 13, and the flow equalizing component, so that the blood on the surface is dried. When the probe 6 is separated from the test tube, the limit ring 10 quickly resets the swab 7 under the action of the spring 11, and the rubber airbag 12 gradually recovers and inhales air into itself through the flow equalizing component, the catheter 13, and the ring tube 24. By drying the blood, when the probe 6 stops instantly, the blood will not be thrown out, thereby avoiding blood contamination of the outside of the detector 1.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the flow equalizing component includes a pair of brackets 14 rotatably mounted outside the conduit 13, an arc-shaped plate 15 is fixedly mounted at the bottom of the pair of brackets 14, a cavity is provided inside the arc-shaped plate 15, a plurality of nozzles connected to the cavity are provided on the inner side of the arc-shaped plate 15, the bottom of the conduit 13 is connected to the inside of the arc-shaped plate 15 through a hose 18, a first torsion spring 16 is provided on the outside of the bracket 14, two ends of the first torsion spring 16 are respectively fixedly connected to the conduit 13 and the bracket 14, a curved surface 17 is provided at the bottom of the arc-shaped plate 15, and the bottom of the arc-shaped plate 15 is higher than the bottom of the probe 6.

[0024] When the probe 6 is inserted into the test tube, the test tube rises and cooperates with the arc surface 17 to squeeze the two arc plates 15 to cause the bracket 14 to deflect, so that the first torsion spring 16 torsional deformation produces a force. When the test tube presses against the bottom of the probe 6 to deflect it, the air flowing in the catheter 13 will enter the cavity through the hose 18 and then be ejected through the nozzle. Since the two arc plates 15 surround the probe 6, the airflow ejected from the nozzle can blow the blood on the probe 6 more comprehensively to make it coagulate. At this time, the coagulated blood is only coagulated on the surface and will not affect the subsequent cleaning of the swab 7. When the test tube is separated from the arc plate 15, the first torsion spring 16 releases the force and restores the bracket 14 and the arc plate 15.

[0025] like Figure 3 and Figure 5 As shown, a shell 19 is fixedly installed on the top of the upper slide plate 9, and a take-up drum 20 is rotatably installed inside the shell 19. Both ends of the take-up drum 20 are sleeved with second torsion springs 23, and the two ends of the second torsion spring 23 are respectively fixedly connected to the inner wall of the shell 19 and the outer side of the take-up drum 20. A pull rope 21 is fixedly connected to the inside of the take-up drum 20, and the pull rope 21 is wound on the take-up drum 20. One end of the pull rope 21 away from the take-up drum 20 extends to the outside of the shell 19 and is fixedly connected to a plug block 22, which is connected to the swab 7.

[0026] When the swab 7 is deflected, the pull rope 21 will be pulled through the plug block 22, thereby causing the take-up drum 20 to rotate, and then twisting the second torsion spring 23 to cause its torsional deformation to generate a force, so that the pull rope 21 is released to adapt to the movement of the swab 7. When the swab 7 is reset, the second torsion spring 23 releases the force to cause the take-up drum 20 to rotate and reset to reel up the pull rope 21. Through the cooperation of the second torsion spring 23, the take-up drum 20, the pull rope 21, and the plug block 22, the swab 7 can be restricted so that after the swab 7 is reset, it can always maintain the same position, thereby preventing the position deviation of the catheter 13 from affecting the next use.

[0027] like Figure 5 As shown, the plug 22 is made of hard rubber, and a slot for the plug 22 is provided on the top of the swab 7. The plug 22 is engaged in the slot by friction with the slot.

[0028] When the swab 7 needs to be replaced, the swab 7 can be separated from the plug 22 .

[0029] like Figure 3 As shown, a threaded opening is provided in the middle of the ball head 5 , the probe 6 is threadedly connected in the threaded opening, and the top of the probe 6 is connected to the delivery pipe inside the detector 1 .

[0030] When the probe 6 needs to be maintained, the user can hold the ball head 5 with one hand to keep it still, and use the other hand to rotate the probe 6 forward to separate it from the ball head 5 to achieve disassembly of the probe 6. Conversely, the probe 6 can be reversed to achieve its combination with the ball head 5.

[0031] like Figure 2 As shown, the outer side of the limiting ring 10 is flush with the outer side of the swab 7 .

[0032] This can avoid the situation where the limiting ring 10 is stuck with the top or bottom of the deflected swab 7, ensuring that the limiting ring 10 can normally restore the swab 7.

[0033] Working principle: When in use, the probe 6 is inserted into the test tube containing the patient's blood, and the blood is extracted and analyzed through the detector 1 and the probe 6, so as to determine whether the patient has prostate cancer. When the test tube is taken away, if the staff makes an error operation, that is, the probe 6 is not completely separated from the test tube, the test tube is moved outward. At this time, the test tube will press against the probe 6 to deflect it outward, thereby causing the ball head 5 and the swab 7 to deflect accordingly. The top and bottom ends of the swab 7 will respectively lift the upper and lower limit rings 10 to cause it to move away from the swab 7 with the slide plate 9, thereby compressing the spring 11 to deform it and generate a force. Since the probe 6 can be adaptively deflected at this time, the probe 6 will not be deformed by the pull of the test tube, and then After the staff realizes the operation problem, they can move the test tube downward and then take the test tube away. After the test tube is separated from the probe 6, the spring 11 releases its force to reset the slide plate 9 and the limit ring 10, thereby squeezing the swab 7 to reset it with the probe 6 to a vertical state. Then the electric push rod 2 extends and the carrier plate 3, the side plate 8, the slide plate 9, and the limit ring 10 descend, thereby bringing the swab 7 down, so that the swab 7 cleans the blood on the probe 6. After the cleaning is completed, the electric push rod 2 is reset, otherwise the swab 7 can be reset, and the analysis of prostate cancer is completed. In the whole process, when an operation error occurs and causes the test tube to pull the probe 6, the probe 6 can be avoided, thereby avoiding the probe 6 from being damaged, thereby improving the operation capacity. Wrong; at the moment when the swab 7 is reset, the swab 7 and the probe 6 will stop instantly, and the inertia will cause the blood attached to the probe 6 to be thrown outward. In order to avoid the above situation, when the probe 6 is inserted into the test tube, the test tube rises and cooperates with the arc surface 17 to squeeze the two arc plates 15, causing the bracket 14 to deflect, so that the first torsion spring 16 torsional deformation produces a force, and when the test tube presses against the bottom of the probe 6 to deflect it, the rubber airbag 12 and the annular tube 24 move accordingly, and the rubber airbag 12 contacts the inner wall of the opening of the carrier plate 3, so that it is squeezed and the air inside it is squeezed out. At this time, the air enters the cavity through the annular tube 24, the conduit 13, and the hose 18, and then is ejected through the nozzle. 15 surrounds the probe 6, so the airflow ejected from the nozzle can blow the blood on the probe 6 more comprehensively to make it coagulate. At this time, the coagulated blood is only coagulated on the surface and will not affect the subsequent cleaning of the swab 7. When the probe 6 is separated from the test tube, the test tube is separated from the arc plate 15, and the first torsion spring 16 releases the force to restore the bracket 14 and the arc plate 15. When the probe 6 is separated from the test tube, the limit ring 10 quickly restores the swab 7 under the action of the spring 11, and the rubber airbag 12 gradually recovers and inhales air into itself through the nozzle, cavity, hose 18, catheter 13, and ring tube 24. By drying the blood, when the probe 6 stops instantly, the blood will not be thrown out, thereby avoiding blood contamination of the outside of the detector 1.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
