Description

Technical Field

[0001] This invention patent relates to the field of penile measuring device technology, specifically to a medical extendable measuring device and method for quick outpatient measurement of penile circumference and length. Background Technology

[0002] Based on clinical experience in andrology, male patients visiting the clinic are generally concerned about the length and circumference of their penis when erect, and exhibit some degree of size anxiety. The commonly used method of direct measurement with a soft measuring tape is often inefficient due to factors such as unfriendly measuring tools, insufficient penile erection, and incorrect measurement techniques, resulting in inaccurate data that causes further worry and distress for patients. Furthermore, the soft measuring tape is in direct contact with the skin, posing a hygiene risk and increasing the possibility of disease transmission; it also requires cleaning after each use, making the procedure rather cumbersome.

[0003] Therefore, there is a need for a user-friendly, convenient, accurate, and clinically appropriate tool or method for measuring penile circumference. To address this issue, a medical extendable measuring device and method for quick outpatient measurement of penile circumference and length are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a medical extendable measuring device and method for quick measurement of penile circumference and length in outpatient settings. It aims to solve the problems of existing penile measurement methods, such as large patient volume, time-consuming and laborious measurement of circumference with a soft ruler, which is also very unhygienic. When measuring length, it is necessary to use a length measuring tool again, which increases working time and workload. The overall measuring tool has poor flexibility and is not convenient for simultaneous, hygienic and rapid use.

[0005] The present invention is achieved as follows: To achieve the above objectives, the present invention provides the following technical solution: a medical extendable measuring device for quick measurement of penile circumference and length in outpatient settings, comprising a penile circumference measuring component, a connector provided at the end of the penile circumference measuring component, and a penile length measuring component movably disposed on the connector.

[0006] The penile circumference measuring device includes a winding drum and a disposable antibacterial paper tape measure placed inside the winding drum. The disposable antibacterial paper tape measure is wound around the inside of the winding drum. A wrapping component is provided at the lower end of the opening of the winding drum, and the disposable antibacterial paper tape measure is pasted on one side of the wrapping component.

[0007] The penis length measuring component includes a traction assembly and a length limiting measuring assembly disposed on the traction assembly, the length limiting measuring assembly being movable through the traction assembly.

[0008] Furthermore, the encircling component includes a chain and a first adsorption sheet disposed on the outer side of one end of the chain. The first adsorption sheet is close to the winding drum, and a second adsorption sheet is disposed on the other end of the chain away from the winding drum. The first and second adsorption sheets can adsorb disposable antibacterial paper rulers.

[0009] Furthermore, the disposable antibacterial paper ruler has a first scale line on the side facing the chain, and after the disposable antibacterial paper ruler is pasted on the chain, one end extends out.

[0010] Furthermore, the traction assembly includes an extension rod and a pin disposed on the inner side of the lower end of the extension rod. The pin is movably connected to the connector, and a traction tube is provided at the upper end of the extension rod.

[0011] Furthermore, one end of the traction tube is equipped with an adsorption device, which is a component made of a magnetic material.

[0012] Furthermore, the length measuring component includes a first limiting tube and a second limiting tube that is movably inserted inside the first limiting tube. The first limiting tube is attracted to the magnetic adsorption fast tube. A first extension piece is provided at the end of the first limiting tube away from the second limiting tube, and a second extension piece is provided at the end of the second limiting tube away from the first limiting tube. A fixing component is provided at the end of the second extension piece away from the second limiting tube.

[0013] Furthermore, a limiting head is provided at the end of the first extension piece away from the first limiting tube, and the limiting head matches the limiting hole opened in the middle of one side of the winding drum.

[0014] Furthermore, the fixing assembly includes an adjusting screw and an adsorption plate disposed at one end of the adjusting screw, the adjusting screw being threadedly connected to the second limiting pipe.

[0015] Furthermore, a second scale line is provided on the outside of the traction tube, a third scale line is provided on the outside of the first limiting tube, and a fourth scale line is provided on the outside of the second limiting tube. The first limiting tube and the extension rod are connected in a fitted manner, and the first limiting tube and the second limiting tube are also connected in a fitted manner. An antibacterial sheet can be attached to the inside of the adsorption plate.

[0016] Another technical solution proposed in this invention: a method for implementing a medical extendable measuring device for quick outpatient measurement of penile circumference and length, comprising the following steps:

[0017] S1: Use two fingers of your left hand to hold the extension rod, and hold the rewind tube in your right hand. Place one side of the disposable antibacterial paper ruler on the penis near the middle. Then, attach the end of the disposable antibacterial paper ruler at one end of the extension rod to the penis. Next, use your right hand to wrap the rewind tube around the penis so that the disposable antibacterial paper ruler is attached to the end of the disposable antibacterial paper ruler at the point where it is exactly wrapped around the penis. Record the first mark at this point, which is the circumference of the penis.

[0018] S2: Pull the first extension plate to the base of the penis and record the data at the third scale line. Then pull the second limiting tube forward along the circumference and rotate the adjusting screw outward to the end. Put the suction plate with the antibacterial sheet on the glans and record the fourth scale line. Finally, the third scale line plus the fourth scale line and the second scale line is the total length of the penis.

[0019] S3: After the measurement is completed, cut the disposable antibacterial paper tape measure from the first mark recorded. The disposable antibacterial paper tape measure used for measurement is the exact length. At this time, pull the remaining disposable antibacterial paper tape measure from the first absorbent plate and pull it out from the winding drum to shorten the length of the disposable antibacterial paper tape measure. Then attach it to the second absorbent plate to complete the replacement of the disposable antibacterial paper tape measure.

[0020] S4: Finally, push the first limiting tube to the end of the traction tube. At this time, the first limiting tube is attracted to the magnetic adsorption fast tube, initially connecting the first limiting tube to the traction tube. Then, push the second limiting tube to the bottom inside the first limiting tube, wind the chain in the reverse direction on the winding drum, insert the limiting head into the limiting hole, and then rotate the adjusting screw to make the adsorption plate adsorb on the other side of the winding drum, thereby winding up the entire measuring device.

[0021] Compared with existing technologies,

[0022] 1. The medical extendable measuring device for quick outpatient measurement of penile circumference and length provided by this invention involves using two fingers of the left hand to hold the extension rod, and the right hand to hold the rewind tube. One side of a disposable antibacterial paper measuring tape is placed near the middle of the penis. Then, the end of the disposable antibacterial paper measuring tape at one end of the extension rod is placed against the penis. The right hand then uses the rewind tube to wrap around the penis until the disposable antibacterial paper measuring tape is completely wrapped around the penis and adheres to the end of the measuring tape. The first graduation at this point is recorded as the penile circumference. After measurement, the measurement is recorded from the... The first graduation line cuts the disposable antibacterial paper ruler to the correct length, reducing its usage and saving costs and resources. The remaining ruler is then pulled apart from the first absorbent plate and pulled out of the winding drum, shortened, and attached to the second absorbent plate, completing the replacement. The design is simple, easy to operate, and allows for reuse after replacement. Furthermore, it keeps hands separate from the ruler, preventing contamination and ensuring hygiene.

[0023] 2. The medical extendable measuring device and method for quick outpatient measurement of penile circumference and length proposed in this invention involves pushing the first limiting tube to the end of the traction tube after measurement. At this time, the first limiting tube is attracted to the magnetic adsorption fastener, initially connecting the first limiting tube to the traction tube. Then, the second limiting tube is pushed all the way into the first limiting tube, the chain is wound in the reverse direction on the winding drum, and the limiting head is inserted into the limiting hole. Then, the adjusting screw is rotated so that the adsorption plate is adsorbed on the other side of the winding drum, thereby winding up the entire measuring device. This makes the measuring device easy to store and carry.

[0024] 3. The medical extendable measuring device and method for quick outpatient measurement of penile circumference and length proposed in this invention involves pulling the first extension piece to the base of the penis and recording the data at the third scale line. Then, the second limiting tube is pulled forward along the circumference, and the adjusting screw is rotated outward to the end. The adsorption plate with the antibacterial sheet is then placed on the glans end, and the data at the fourth scale line is recorded. Finally, the third scale line plus the fourth scale line and the second scale line equals the total length of the penis. The operation is simple, and the length can be measured quickly and simultaneously with the measurement of penile circumference, reducing the operation process and the need to change measuring tools. It also improves the versatility of the measuring device and the portability of the tool. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0038] Please see Figure 1-4 A medical extendable measuring device for quick measurement of penile circumference and length in outpatient settings, including a penile circumference measuring component 1 and a connector 3 disposed at the end of the penile circumference measuring component 1, wherein a penile length measuring component 2 is movably disposed on the connector 3.

[0039] The penile circumference measuring component 1 includes a winding barrel 11 and a disposable measuring tape 12 disposed inside the winding barrel 11. The disposable measuring tape 12 is wound around the inside of the winding barrel 11. A circumferential member 13 is provided at the lower end of the opening of the winding barrel 11, and the disposable measuring tape 12 is attached to one side of the circumferential member 13.

[0040] The encircling component 13 includes a chain 131 and a first adsorption sheet 132 disposed on the outer side of one end of the chain 131. The first adsorption sheet 132 is close to the winding drum 11, and a second adsorption sheet 133 is disposed on the other end of the chain 131 away from the winding drum 11. The first adsorption sheet 132 and the second adsorption sheet 133 can adsorb the disposable measuring tape 12.

[0041] The disposable measuring tape 12 has a first scale line 121 on the side facing the chain 131. After the disposable measuring tape 12 is pasted on the chain 131, one end extends out. After the disposable measuring tape 12 is pasted on the chain 131, the other end of the disposable measuring tape 12 can be pasted to the extended end of the disposable measuring tape 12 without being stuck by the chain 131, thus improving the accuracy of the test.

[0042] Please see Figure 5-8 The penis length measuring component 2 includes a traction assembly 21 and a length limiting measuring component 22 disposed on the traction assembly 21, the length limiting measuring component 22 being movable through the traction assembly 21.

[0043] The traction assembly 21 includes an extension rod 211 and a pin 212 disposed on the inner side of the lower end of the extension rod 211. The pin 212 is movably connected to the connector 3. The upper end of the extension rod 211 is provided with a traction tube 213. One end of the traction tube 213 is provided with an adsorption block 214, which is a component made of a magnetic material.

[0044] Specifically, when measuring penile circumference, use two fingers of the left hand to hold the extension rod 211, and the right hand to hold the winding drum 11. Place one side of the disposable measuring tape 12 around the middle of the penis, then place the end of the disposable measuring tape 12 at one end of the extension rod 211 against the penis. Then, use the right hand to wrap the winding drum 11 around the penis until the disposable measuring tape 12 is completely wrapped around the penis and its end is against the end. Record the first graduation line 121 at this point; this is the penile circumference. After measurement, measure from the recorded first graduation line 121... The disposable measuring tape 12 is cut to the exact length used for measurement, reducing its usage and saving costs and resources. The remaining disposable measuring tape 12 is then initially pulled apart from the first adsorption plate 132 and pulled out from the winding drum 11 to shorten its length. It is then attached to the second adsorption plate 133, completing the replacement of the disposable measuring tape 12. The structure is simple, the operation is convenient, and it is easy to reuse after replacement. Moreover, both hands are free from the disposable measuring tape 12, preventing contamination and making it more hygienic.

[0045] The length measuring component 22 includes a first limiting tube 221 and a second limiting tube 222 that is movably inserted inside the first limiting tube 221. The first limiting tube 221 is magnetically attracted to the adsorption block 214. A first extension piece 223 is provided at the end of the first limiting tube 221 away from the second limiting tube 222. A limiting head 224 is provided at the end of the first extension piece 223 away from the first limiting tube 221. The limiting head 224 matches the limiting hole 111 opened in the middle of one side of the winding drum 11. A second extension piece 225 is provided at the end of the second limiting tube 222 away from the first limiting tube 221. A fixing component 226 is provided at the end of the second extension piece 225 away from the second limiting tube 222.

[0046] The fixing assembly 226 includes an adjusting screw 2261 and an adsorption plate 2262 disposed at one end of the adjusting screw 2261. The adjusting screw 2261 is threadedly connected to the second limiting tube 222.

[0047] Specifically, after the measurement is completed, the first limiting tube 221 is pushed to the end of the traction tube 213. At this time, the first limiting tube 221 and the adsorption block 214 are magnetically attracted, initially connecting the first limiting tube 221 and the traction tube 213. Then, the second limiting tube 222 is pushed to the bottom inside the first limiting tube 221, the chain 131 is wound in the reverse direction on the winding drum 11, and the limiting head 224 is inserted into the limiting hole 111. Then, the adjusting screw 2261 is rotated so that the adsorption plate 2262 is adsorbed on the other side of the winding drum 11, thereby winding up the entire measuring device, which is convenient for storage and carrying.

[0048] Please see Figure 7-10The outer side of the traction tube 213 is provided with a second scale line 215, the outer side of the first limiting tube 221 is provided with a third scale line 2211, and the outer side of the second limiting tube 222 is provided with a fourth scale line 2221. The first limiting tube 221 and the extension rod 211 are connected in a fitted manner, and the first limiting tube 221 and the second limiting tube 222 are also connected in a fitted manner. The friction is large during the pulling process, which facilitates pulling and adjustment. An antibacterial sheet 2263 can be attached to the inner side of the adsorption plate 2262.

[0049] Specifically, when measuring penile length, the first extension piece 223 is pulled to the base of the penis, and the data at the third scale line 2211 is recorded. Then, the second limiting tube 222 is pulled forward along the circumference, and the adjusting screw 2261 is rotated outward to the end. The suction plate 2262 with the antibacterial sheet 2263 is placed on the glans, and the fourth scale line 2221 is recorded. Finally, the third scale line 2211 plus the fourth scale line 2221 and the second scale line 215 is the total length of the penis. The operation is simple, and the length can be measured quickly and simultaneously with the measurement of penile circumference, reducing the operation process and the need to change measuring tools, and also improving the versatility of the measuring device and the portability of the tool.

[0050] Another technical solution proposed in this invention: a method for implementing a medical extendable measuring device for quick outpatient measurement of penile circumference and length, comprising the following steps:

[0051] Step 1: Use two fingers of your left hand to hold the extension rod 211, and hold the take-up tube 11 in your right hand. Place one side of the disposable measuring tape 12 on the penis near the middle, then attach the end of the disposable measuring tape 12 at one end of the extension rod 211 to the penis. Then, use your right hand to wrap the take-up tube 11 around the penis, so that the disposable measuring tape 12 is attached to the end of the disposable measuring tape 12 at the point where it is exactly wrapped around the penis. Record the first scale line 121 at this time, which is the circumference of the penis.

[0052] Step 2: Pull the first extension plate 223 to the base of the penis and record the data at the third scale line 2211. Then pull the second limiting tube 222 forward along the circumference and rotate the adjusting screw 2261 outward to the end. Put the suction plate 2262 with the antibacterial plate 2263 on the glans and record the fourth scale line 2221. Finally, the third scale line 2211 plus the fourth scale line 2221 and the second scale line 215 is the total length of the penis.

[0053] Step 3: After the measurement is completed, cut the disposable measuring tape 12 from the first scale line 121. The disposable measuring tape 12 used for the measurement is the exact length. At this time, pull the remaining disposable measuring tape 12 from the first adsorption plate 132 and pull it out from the winding drum 11 to shorten the length of the disposable measuring tape 12. Then attach it to the second adsorption plate 133 to complete the replacement of the disposable measuring tape 12.

[0054] Step 4: Finally, push the first limiting tube 221 to the end of the traction tube 213. At this time, the first limiting tube 221 and the adsorption block 214 are magnetically attracted, initially connecting the first limiting tube 221 and the traction tube 213. Then, push the second limiting tube 222 into the first limiting tube 221 to the bottom, and wind the chain 131 in the reverse direction onto the winding drum 11. Insert the limiting head 224 into the limiting hole 111, and then rotate the adjusting screw 2261 so that the adsorption plate 2262 is adsorbed on the other side of the winding drum 11, thereby winding up the entire measuring device.
