Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a wearable device for nuclear medicine imaging examination that can prevent urine leakage. Background Art

[0002] Nuclear medicine's SPECT / CT, PET / CT, and PET / MR imaging have been widely used in clinical practice, providing solid metabolic imaging evidence for the diagnosis and treatment of diseases. Most nuclear medicine examinations require injection of imaging agents, which contain a small amount of radioactive drugs. If the drug is excreted through the kidneys, the patient who has been injected with radioactive drugs will have radioactivity in the urine. The elderly, patients with prostate and bladder diseases, and female patients with pelvic floor diseases often have difficulty holding urine during the examination and cannot hold it, resulting in partial urine leakage or uncontrolled urine overflow, and even excretion on the examination bed during the examination.

[0003] Since urine contains radioactive drugs, nuclear medicine instruments will collect radioactive areas, causing the patient's image to be covered by urine or mixed with the radioactivity in the excrement, etc., resulting in varying degrees of image quality being affected, and in severe cases, even the diagnosis cannot be completed. On the other hand, if urine is contaminated on the machine examination bed, causing the bed board to be contaminated with radioactive urine, the contaminated bed board will always be radioactively adhered to the surface of the bed, and the radioactive urine cannot be wiped clean. The bed board can only be used for the imaging of the next patient after the area contaminated by the radioactive urine decays completely by itself (the image will not be affected at this time). Commonly used radioactive imaging agents such as 18F and 99TcO4-salts are excreted through urine. The decay time of radioactive drugs is relatively long. For example, the half-life of 18F, which is most commonly used in PET imaging, is about 110 minutes, while the half-life of 99TcO4, which is most commonly used in SPECT imaging, is about 6 hours, and the half-life of 131I is 8 days. Normally, once the bed board is contaminated, it takes more than ten hours to collect the samples again, which greatly delays the normal medical work.

[0004] The current common practice in the market is to put a cloth mat on the bed board, or let the patient wear diapers, both of which have their disadvantages. The cloth mat cannot bear too much urine from the patient. Once the patient is too incontinent, it will still cause the bed board to be contaminated. Diapers are better than cloth mats, but they cannot bear too much urine and may leak. In addition, it is more troublesome for patients to change diapers. At the same time, due to the openness of diapers, they are prone to secondary radioactive contamination. Utility Model Content

[0005] The utility model aims to solve the problem of radioactive contamination caused by urine excretion and seepage of the examinee in the above-mentioned existing nuclear medicine imaging examinations, and provides a wearable device for nuclear medicine imaging examinations that can prevent urine leakage, which can not only prevent the examinee's urine excretion from contaminating the examination bed during the examination, but also protect the staff or other personnel from contacting with radioactive liquids, and is easy to use and replace.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wearable device for nuclear medicine imaging examination that can prevent urine leakage, composed of a protective pad and a wearable structure; the protective pad includes a waterproof bottom layer and a water-absorbing surface layer thereon; the wearable structure is in a T-shape as a whole, and consists of a wearable body and a left wing and a right wing on both sides thereof; first adhesive areas are arranged at both ends of the outer side of the lower edge of the wearable body and the inner sides of the left wing and the right wing, and the outer side of the lower edge of the wearable body and the inner sides of the left wing and the right wing can be firmly connected through the first adhesive area. When the patient wears the wearable structure, the patient's groin can be completely wrapped to ensure that radioactive urine will not overflow and pollute; the rear part of the wearable structure is connected to the water-absorbing surface layer at the center of the protective pad; a pull-out structure is arranged at both upper and lower ends of the protective pad, and the pull-out structure is a double-layer hollow structure with a pull-out rope passing through it.

[0008] Specifically, the waterproof bottom layer is made of waterproof non-woven fabric, which can ensure that radioactive urine will not penetrate and protect the bed board from radioactive contamination.

[0009] Specifically, an ionizing radiation identification area may be provided in the middle of the back side of the waterproof bottom layer.

[0010] Specifically, the water-absorbing surface layer is made of highly water-absorbent cotton cloth.

[0011] Specifically, the water-absorbent surface layer and the waterproof bottom layer are both square structures. The water-absorbent surface layer is slightly smaller than the waterproof bottom layer. The water-absorbent surface layer is tightly connected to the waterproof bottom layer, and can further absorb urine leaked from the wearing structure of the patient.

[0012] Specifically, the wearable structure has a layer of highly absorbent material built into it, so that the patient's urine can be absorbed as completely as possible.

[0013] Specifically, the rear portion of the wearing structure is connected to the upper surface of the water-absorbing surface layer.

[0014] Furthermore, a second adhesive area is provided at the center position of the rear portion of the wearing structure and the center position of the upper surface of the water-absorbing surface layer, and the second adhesive area is detachably connected.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] Firstly, the wearable device for nuclear medicine imaging examination that can prevent urine leakage of the utility model adopts a structural form that combines a protective pad and a wearable structure. If the patient becomes incontinent during the examination, the utility model can basically absorb all the overflowed radioactive urine of the person being examined through the highly absorbent material layer built into the wearable structure and the absorbent surface layer of the highly absorbent cotton cloth material of the protective pad. At the same time, the waterproof bottom layer of the waterproof non-woven fabric material can further ensure that the radioactive urine will not penetrate. The above-mentioned multiple protection schemes can prevent the examination bed board from being contaminated by radioactivity.

[0017] Secondly, the wearable device for nuclear medicine imaging examination that can prevent urine leakage of the utility model adopts a structural form that combines a protective pad and a wearable structure. If the urine of the examinee contaminates the water-absorbing surface of the protective pad, the medical staff can immediately replace the entire wearable device as a whole; if the urine of the examinee only contaminates the wearable structure, the medical staff can only partially remove the contaminated wearable structure and replace it with a new one. Therefore, the utility model also has the advantages of easy disassembly and replacement of the structure, and appropriate cost savings.

[0018] Third, the wearable device for nuclear medicine imaging examinations that can prevent urine leakage of the utility model has a pull-out structure at both ends of the protective pad, and the internal pull-out rope can be directly retracted as a whole to further prevent radioactive spillage. When the staff or other personnel handle the contaminated wearable device after use, they can avoid contact with radioactive liquid, thereby avoiding the occurrence of secondary radioactive contamination. The back of the protective pad of the utility model is also provided with an ionizing radiation identification area, which can be set with an ionizing radiation identification to achieve the purpose of identification reminder and prevent uninformed people from accidentally touching radioactive pollutants.

Therefore, when the examinee uses the wearable device, the wearable structure 2 can completely wrap the patient's groin to ensure that radioactive urine will not overflow and pollute. The wearable structure 2 has a built-in high water-absorbent material layer, which can absorb the patient's urine as much as possible. The protective pad 1 includes a waterproof bottom layer 6 and a water-absorbent surface layer 7 thereon, and the waterproof bottom layer 6 and the water-absorbent surface layer 7 are pressed or sewn to ensure their structural strength. The water-absorbent surface layer 7 and the waterproof bottom layer 6 are both square. The absorbent surface layer 7 is made of highly absorbent cotton cloth. The absorbent surface layer 7 is slightly smaller than the waterproof bottom layer 6, and can further absorb urine that may leak from the gap between the wearable structure 2 and the human body. The waterproof bottom layer 6 is made of waterproof non-woven fabric, which further prevents radioactive urine from penetrating into the bed board and causing radioactive contamination. The protective pad 1 has a double-layer structure consisting of a waterproof bottom layer 6 and an absorbent surface layer 7 thereon, which as a whole ensures that radioactive urine will not overflow and pollute.

When using the wearable device that can prevent urine leakage, if the urine of the person being examined contaminates the water-absorbing surface layer 7 of the protective pad 1, the medical staff can immediately replace the entire wearable device; if the urine of the person being examined only contaminates the wearing structure 2, the medical staff can only tear off the adhesive, remove the original wearing structure 2, and replace it with a new wearing structure 2, so as to achieve the purpose of easy disassembly and replacement of the wearable device. Pull-out structures 5 are provided at both the upper and lower ends of the protective pad 1. The pull-out structures 5 are arranged in parallel at the upper and lower ends of the protective pad 1. The pull-out structure 5 is a double-layer hollow structure with a pull-out rope 4 inserted inside. The pull-out rope 4 can be tightened and gathered to further prevent the spillage of radioactive urine. At the same time, when the staff handles the contaminated (used) wearable device, it can protect the staff from contact with radioactive liquid and avoid secondary radioactive contamination. See Figure 3 An ionizing radiation identification area 11 is provided in the middle of the back of the waterproof bottom layer 6, and is marked with the words "Beware of Radiation" and may also be marked with other warning statements to achieve the purpose of identification and reminder during use and disposal, and prevent uninformed people from accidentally touching radioactive pollutants.
