Abstract
Description
Technical Field
[0001] The invention relates to the technical field of urology nursing instruments, in particular to a urinary catheter fixer. Background Art
[0002] Currently, in urological surgery nursing, after a catheter is inserted into a patient, the part of the catheter that is retained outside the body needs to be fixed with a fixator to improve the stability of the catheter and ensure the safety of the patient's catheter. Traditional fixators can be roughly divided into patch-type fixators and strap-type fixators. When used, patch-type fixators need to be fixed and pasted on the inner thigh, which has high requirements on the patient's skin and fixator quality. Later, with the activities of the personnel, the patch-type fixator is easy to slowly peel off from the thigh. Since this process is relatively slow, sometimes it is difficult for the patient to find it in time even after it has completely fallen off, which may lead to medical safety accidents. In order to cope with this phenomenon and ensure safety, medical staff need to check them frequently. If local peeling is found, it is necessary to press it in time and stick it close to the skin or even replace it. If it is not discovered and cared for in time, the peeled sticky layer will lose its sticky effect due to the attachment of dust and wool from the clothes, and then the patch-type fixator needs to be completely replaced. Completely replacing the patch-type fixator will not only cause discomfort to the patient, but also increase the workload of medical staff. Moreover, frequent replacement of patch-type fixators will affect the patient's recovery and increase the burden on the patient. When the strap-type fixator is used, it needs to be tied to the patient's thigh. Although this fixation method can prevent the fixator from falling off, the strap exerts pressure on the patient's thigh for a long time, which will cause serious discomfort to the patient and even cause pressure injury. Therefore, further improvements are needed to the catheter fixator. Summary of the invention

The initial color of the temperature-sensitive color-changing sticker is black, and the color-changing temperature of the temperature-sensitive color-changing sticker is 33 degrees Celsius. It becomes transparent when heated. A high-transmittance silicone layer is provided on one side of the temperature-sensitive color-changing sticker, and a light-shielding sticker is provided on one side of the high-transmittance silicone layer. A protective patch is provided on one side of the light-shielding sticker; a micro light strip 16 and a vacuum glass partition 17 are also fixedly provided on the inner wall of the fixing seat, and the micro light strip is provided just above the high-transmittance silicone layer. A heat dissipation groove 18 is provided on the inner wall of the fixing seat, and the micro light strip 16 is provided on the inner wall of the heat dissipation groove, and the heat dissipation groove 18 is used to dissipate the heat of the micro light strip 16, and the vacuum glass partition 17 is used to insulate the micro light strip 16, so as to reduce the influence of the heat of the micro light strip 16 on the temperature-sensitive color-changing sticker 31; the micro light strip Located above the disposable temperature sensing patch and connected to the battery circuit, the vacuum glass partition is located between the micro light strip and the disposable temperature sensing patch, and both sides of the fixed seat are fixedly connected with thermal deformation straps 4, wherein the thermal deformation straps include a fixed shell 41, an electric heating block 42, a thermal deformation memory metal wire 43 and a Velcro strap 44, one side of the fixed shell is fixedly connected to the fixed seat, and the inner wall of the fixed shell is fixedly connected with the electric heating block, the electric heating block is connected to the battery circuit, and one side of the electric heating block is fixedly connected with a thermal deformation memory metal wire made of nickel-titanium memory alloy, the thermal deformation temperature of the thermal deformation memory metal wire is 40 degrees Celsius, and the human body temperature is generally 36.5 degrees Celsius. Under normal circumstances, the patient's body temperature will not cause the deformation memory metal wire 43 to deform, and the other side of the fixed shell is fixedly connected with a Velcro strap, and a chamber 441 is arranged in the Velcro strap, and one end of the thermal deformation memory metal wire extends into the chamber and is fixed to the inner wall of the chamber.
[0028] During the use of the catheter holder, the sticking position is first selected. The ideal sticking position is the inner side of the middle thigh, which is a certain distance away from the leg root. This place is relatively flat and not easy to sweat. Medical staff of patients with leg hair should shave their leg hair and clean the surface. After the preparation work is completed, a disposable temperature-sensing patch 3 is taken and stuck on the connecting block 14 on the inner wall of the fixing seat 1. Combined with the disposable temperature-sensing patch 3, the fixing seat 1 can be stuck to the inner side of the patient's thigh. When the disposable temperature-sensing patch 3 is peeled off from the patient's skin, the temperature received by the disposable temperature-sensing patch 3 will decrease. When the local temperature of the disposable temperature-sensing patch 3 decreases, the originally transparent temperature-sensing color-changing sticker 31 will be partially The light source of the micro light strip 16 will be blocked, and some of the light sources will not be able to be transmitted to the light-controlled switch controller 12 through the matrix light guide assembly 15. The light-controlled switch controller 12 will automatically turn on after detecting the reduction in brightness, so that the battery 13 and the electric heating block 42 form a direct passage. The heat emitted by the electric heating block 42 will cause the thermal deformation memory metal wire 43 to shrink and deform. The shrinking thermal deformation memory metal wire 43 will tighten the Velcro strap 44, and the Velcro strap 44 will drive the Velcro strap 44 to tighten during the tightening process. The fixing seat 1 fits the thigh, so that the disposable temperature-sensing patch 3 that was originally peeled off can fit the skin of the person again, so that when the fixer is peeled off, the fixer can automatically fit the skin, without the need for frequent inspection and care, reducing the workload of medical staff, because the fixer can fit the skin again in time when it is peeled off, the disposable temperature-sensing patch 3 on the fixer is not easy to be attached to the dust and wool on the clothes and lose the sticky effect, which can greatly increase the service life of the fixer, and there is no need to change it frequently to avoid causing discomfort to the patient and affecting the patient's recovery progress; the thermal deformation bandage 4 mainly plays the role of protection and driving the fixing seat 1 to tighten. When it is initially worn, the thermal deformation bandage 4 The strap 4 only fits and surrounds the thigh. When the fixing seat 1 is tightened to make the disposable temperature-sensing patch 3 fit the person's skin again, the light-controlled switch controller 12 will be turned off, and the electric heating block 42 in the thermal deformation strap 4 will no longer generate heat. Then the thermal deformation memory metal wire 43 will extend and recover. Without the contraction and pulling force of the thermal deformation memory metal wire 43, the Velcro strap 44 can still maintain the initial assembly state and will not squeeze the person's thigh, so as to avoid applying pressure on the patient's thigh for a long time and causing discomfort to the patient. Subsequently, once the fixer is peeled off, the thermal deformation strap 4 will be tightened again, which can completely prevent the fixer from falling off inadvertently and avoid the occurrence of medical accidents.
[0029] The initial state of the temperature-sensitive color-changing sticker 31 is black, and the color-changing temperature of the temperature-sensitive color-changing sticker 31 is 33 degrees Celsius, and it becomes transparent when exposed to heat. During use, the black color has a good shading effect, which can make the light brightness drop more obvious. The human body temperature is generally 36.5 degrees Celsius. After the light-shielding sticker 33 contacts the patient's skin, the heat is finally transferred to the temperature-sensitive color-changing sticker 31 through the light-shielding sticker 33 and the high-transparency silicone layer 32. The temperature will still not be lower than 33 degrees Celsius, ensuring that the disposable temperature-sensitive patch 3 can become transparent when it is attached. During use, when the micro-light strip 16 irradiates the high-transparency silicone layer 32, the matrix-distributed first optical fiber 151 can fully receive the light source on the high-transparency silicone layer 32 and transmit it to the second optical fiber 153 through the condenser 152. Finally, the light-controlled switch controller 12 judges the intensity of the light output by the second optical fiber 153 to choose whether to turn it on.
[0030] Specifically:
[0031] 1. Select the sticking position. The ideal sticking position is the inner side of the middle thigh, which is a certain distance from the groin. This place is relatively flat and not easy to sweat. Medical staff should shave the leg hair of patients with leg hair and clean the surface. After the preparation is completed, take a disposable temperature-sensing patch and stick it on the connecting block on the inner wall of the fixed seat. Combined with the disposable temperature-sensing patch, the fixed seat can be stuck to the inner thigh of the patient. When the disposable temperature-sensing patch is peeled off from the patient's skin, the temperature received by the disposable temperature-sensing patch will decrease. When the local temperature of the disposable temperature-sensing patch decreases, the originally transparent temperature-sensing color-changing sticker will turn black. Although the temperature-sensing color-changing sticker of the part that continues to be sticky will remain transparent, the black area will still block the light source emitted by the micro light strip. After the local light source is blocked, part of the light source will not be able to be transmitted to the light-controlled switch through the matrix light guide component. The light-controlled switch controller will automatically open after detecting that the brightness is reduced, so that the battery and the electric heating block form a direct path, and the heat emitted by the electric heating block will cause the thermal deformation memory metal wire to shrink and deform, and the shrinking thermal deformation memory metal wire will tighten the Velcro strap. During the tightening process, the Velcro strap will drive the fixing seat to fit the thigh, so that the disposable temperature-sensing patch that was originally peeled off can fit the skin of the person again, so that when the fixator is peeled off, the fixator can automatically fit the skin, without the need for frequent inspection and care, reducing the workload of medical staff, because the fixator can fit the skin again in time when it is peeled off, the disposable temperature-sensing patch on the fixator is not easy to adhere to dust and wool from clothes and lose its sticky effect, which can greatly increase the service life of the fixator, and there is no need for frequent replacement, so as to avoid causing discomfort to the patient, affecting the patient's recovery progress, and reducing the burden on the patient.
[0032] 2. The thermal deformation strap mainly plays a protective role and drives the fixing seat to tighten. When it is first worn, the thermal deformation strap only fits and surrounds the thigh. When the fixing seat is tightened so that the disposable temperature-sensing patch fits the person's skin again, the light-controlled switch controller will be turned off, and the electric heating block in the thermal deformation strap will no longer generate heat. Then the thermal deformation memory metal wire will extend and recover. Without the contraction and pulling force of the thermal deformation memory metal wire, the Velcro strap can still maintain the initial assembly state and will not squeeze the person's thigh, so as to avoid long-term pressure on the patient's thigh and cause discomfort to the patient. Subsequently, once the fixator is peeled off, the thermal deformation strap will be tightened again to completely prevent the fixator from falling off inadvertently and avoid medical accidents.
[0033] In summary, when the fixator is peeled off, the fixator can automatically fit the skin, without the need for frequent inspection, care and replacement, thus reducing the workload of medical staff. Since the fixator can fit the skin again in time when it is peeled off, the adhesive layer on the fixator is not easy to adhere to dust, dandruff and wool from clothes and lose its adhesive effect, which can greatly increase the service life of the fixator. There is no need to replace it frequently to avoid causing discomfort to the patient and affecting the patient's recovery progress. The fixator can be completely prevented from falling off inadvertently, medical accidents can be avoided, and patient safety can be ensured.
