Description

Technical Field

[0001] The present application relates to the field of clinical medical testing instruments, and in particular to a portable anal pressure detector. Background Art

[0002] As people age and their physical functions decline, the incidence of fecal incontinence increases. It's a common problem in hospitals, nursing homes, and community care settings, particularly among the elderly, critically ill, and bedridden patients, with a prevalence rate of 46-54.4%. Fecal incontinence can also lead to complications, causing significant distress and psychological distress for patients while also creating numerous challenges for caregivers.

[0003] An anal pressure tester is an important medical device used to detect and assess anal function. It can help diagnose anal incontinence and plays a vital role in the recovery phase after anorectal surgery. Existing anal pressure testers consist of a detector and a probe connected to the detector. The probe is inserted into the rectum to measure the pressure inside the anus and rectum, converting the pressure changes into electrical signals. Medical personnel use the corresponding data recorded by the probe to understand the patient's condition. However, this anal pressure tester is large and inconvenient to carry. Summary of the Invention

[0004] In order to improve the convenience of the anal pressure tester and facilitate medical personnel to carry it with them, the present application provides a portable anal pressure tester.

[0005] The present application provides a portable anal pressure detector using the following technical solutions:

[0006] A portable anal pressure detector, comprising a rod body as a main structure, characterized in that it also includes:

[0007] A detection head is provided at one end of the rod body, wherein one end of the detection head is spherical or ellipsoidal, and the other end of the detection head is cylindrical, and the two ends are smoothly connected;

[0008] A telescopic assembly is provided inside the rod body and connected to the detection head, so that the detection head is telescoped to the end of the rod body;

[0009] A cap is clamped to one end of the rod body corresponding to the detection head, and is used to protect the detection head;

[0010] The display component is arranged at the end of the rod body away from the detection head.

[0011] By adopting the above technical solution, the anal pressure detector is integrated into a rod body. The diameter of the rod body should be the thickness of a normal adult's finger, or similar to the thickness of a pen. The overall length is actually recommended to be 15-20 cm, which is easy to carry.

[0012] The front end of the anal pressure detector is equipped with a pressure sensor to detect the pressure in the rectum. The medical staff first removes the cap and then controls the telescopic component to change the extension length of the detection head to the appropriate length so that the detection head can be inserted into the correct position to ensure the correct position of the pressure measurement. The patient applies force, and the pressure sensor detects the pressure and converts it into an electrical signal. The medical staff observes the value through the display component and makes a judgment.

[0013] To avoid causing harm to the patient, one end of the detection head, more precisely the protruding end, should be set to a smooth round or oval shape and can be coated with coupling agent to facilitate insertion into the patient's anus.

[0014] Optionally, also include:

[0015] The clamping portion is arranged at an end of the rod body away from the detection head, and the clamping portion is adapted to the cap and is used for clamping the cap.

[0016] By adopting the above technical solution, after removing the cap, the cap is clamped on the clamping part at the other end of the rod body to prevent medical staff from forgetting the placement of the cap or losing the cap. In addition, the cap extends the length of the other end of the rod body, or the hand-held end of the pressure tester of the medical staff, making it easier for medical staff to operate.

[0017] Optionally, an arc groove structure adapted to the shape of the detection head is provided at one end of the rod body close to the detection head;

[0018] A padding paper is provided in the arc groove structure, the surface area of ​​the padding paper is larger than the bottom wall area of ​​the arc groove, so that the side edge of the padding paper extends out of the arc groove, and a perforation is opened in the center part of the padding paper, and the diameter of the perforation is smaller than the maximum diameter of the detection head.

[0019] By adopting the above technical solution, since the detection head is spherical or ellipsoidal, the inside of the rod body needs to be set into a spherical or ellipsoidal shape corresponding to the outer shape of the detection head, so as to accommodate the detection head after the detection head is inserted into the rod body;

[0020] When the detection head is inserted into the patient's anus, if the rod body contacts the patient's skin at the corresponding position, the bacteria in the patient's anus will adhere to the rod body, which is likely to cause anal bacterial infection in subsequent patients. Therefore, before the detection process, a padding paper needs to be placed in the arc groove. One piece of padding paper is used for each patient. The larger the padding paper area, the part between the rod body and the detection head can cover the entire arc groove end, isolating the rod body and the detection head;

[0021] After removing the test head from the patient's anus, the medical staff removes the paper pad and removes it from the test head through the middle perforated part. Before removal, the medical staff bends the paper pad toward the test head so that the paper pad covers the test head, and scrubs the test head with a detergent.

[0022] Optionally, a clamping block is provided on the outer wall of the rod body near the arc groove for clamping the edge of the padding paper, and a clamping hole is provided on the edge of the padding paper near the corresponding clamping block.

[0023] By adopting the above technical solution, there should be at least three clamping blocks distributed along the circumference of the outer wall of the rod body, and the three clamping blocks should be distributed at equal intervals along the circumference of the outer wall of the rod body. The edge part of the padding paper corresponds to the opening of the clamping block, so that the padding paper at the edge part is clamped to the clamping block, fixing the padding paper to prevent it from falling off.

[0024] Optionally, also include:

[0025] A paper slot is provided at an end of the rod body away from the detection head, and is used to hold the pad paper. The rod body is provided with a paper drawer corresponding to the paper slot and plugged into the paper slot. The diameter of one end of the paper drawer is equal to the diameter of the rod body, so as to close the paper slot.

[0026] The cover cap is clamped on the end of the paper drawer.

[0027] By adopting the above technical solution, the paper drawer is in the shape of a drawer, and is matched with the paper slot to hold the pad paper, that is, the pad paper is stored in the paper drawer. When replacing the pad paper, the medical staff opens the paper drawer, takes out a piece of pad paper from the paper drawer, and then closes the paper drawer;

[0028] To facilitate the extraction of the paper drawer, medical personnel can connect the cover cap to the paper drawer to facilitate opening and closing the paper drawer.

[0029] Optionally, the display component includes:

[0030] A status light is provided in the middle portion of the rod body;

[0031] The display screen is arranged on the outer wall of the end of the rod body away from the detection head.

[0032] By adopting the above technical solution, the status light is used to intuitively display whether the pressure data at the patient's anus is within the normal range, allowing medical staff to directly observe. When the status light is abnormal, medical staff observe the display screen to obtain pressure data, which can improve detection efficiency to a certain extent.

[0033] Among them, the status light is set with reference to the actual value range. When the pressure value range detected by the detection head is 120-170 mmHg, the light is green, when it is less than 120 mmHg, the light is off, and when it is greater than 170 mmHg, the light is red.

[0034] Optionally, the telescopic component includes:

[0035] A micro electric push rod is arranged inside the rod body, and the end of the piston rod is connected to the detection head to drive the detection head to perform telescopic movement;

[0036] The support frame is arranged inside the rod body and corresponds to the micro electric push rod. The support frame is used to support the micro electric push rod.

[0037] By adopting the above technical solution, the piston rod of the micro electric push rod should be aligned with the center part of the detection head, and the support frame should be set according to the actual distance difference between the micro electric push rod and the inner wall of the rod body. The support frame should retain perforations connecting the internal spaces at both ends of the rod body to lay signal lines for data transmission of the pressure sensor.

[0038] Optionally, also include:

[0039] A control component is arranged at one end of the rod body away from the detection head and is used to control the micro electric push rod and the display screen.

[0040] By adopting the above technical solution, the control component generally adopts a welded circuit board with multiple computing components, or a specific micro-computing unit, which should be set at the end of the rod body away from the detection head and at the same time play a counterweight balancing role. It should be set close to the display screen to reduce the length of the control line and reduce the failure rate of the control line. BRIEF DESCRIPTION OF THE DRAWINGS

The arc groove 12 is hemispherical or hemispherical, and a through hole is provided at the bottom of the arc groove 12 to connect to the interior of the rod body 1.

[0049] Reference Figure 1 and Figure 2 A test head is inserted into the end of the rod body 1 near the arc groove 12. One end of the test head, or the head portion, is spherical or semi-ellipsoidal, fitting the arc groove 12, with its outer wall fitting within the arc groove 12. The other end, or the tail portion, is cylindrical and inserts into a through-hole defined at the bottom of the arc groove 12. The tail portion extends through the through-hole into the rod body 1, creating a smooth connection between the head and tail. The design of the test head facilitates insertion into a patient's anus by medical personnel.

[0050] Reference Figure 3 and Figure 4 The end of the rod body 1 facing away from the test head has a paper slot 17, which contains a padding paper 3. A new padding paper 3 is folded and stored in the slot 17. The unfolded, straight-surface area of ​​the padding paper 3 is larger than the end area of ​​the rod body 1. Furthermore, it is larger than the bottom wall area of ​​the arc groove 12. When the padding paper 3 is placed in the arc groove 12, its edge extends beyond the arc groove 12, covering the portion of the rod body 1 sidewall near the arc groove 12. A central hole 31 is defined in the center of the padding paper 3. The diameter of the central hole 31 is smaller than the maximum diameter of the test head and larger than the diameter of the test head's tail. In this embodiment, the padding paper 3 is used to prevent the patient's anus from contacting the rod body 1 when the test head is inserted into the patient's anus, providing a safe barrier. It can also be used by medical personnel to wipe the test head after a patient has finished testing.

[0051] Reference Figure 1 A section of the outer wall of the rod body 1 close to the arc groove 12 is formed with multiple clamping blocks 13, and at least three are set, and the three clamping blocks 13 are evenly spaced and distributed in a circumferential surface; the edge portion of the padding paper 3 is provided with holes corresponding to the clamping blocks 13. When the padding paper 3 is placed in the arc groove 12, the holes on the edge of the padding paper 3 are clamped with the clamping blocks 13 to fix the padding paper 3.
