However, the traditional mercury thermometer is very easy to slip and crash, resulting in mercury pollution
The common reasons are: ①Children love to move and cry easily, and the phenomenon of the thermometer slipping is particularly prominent; ②It is the phenomenon that the thermometer crashes often occurs when adults are especially older, and middle school students are playing with their mobile phones while measuring their body temperature, and even a few college students are playing with their mobile phones (wandering) Turn the thermometer upside down while using it; ③ Especially the thermometer is small and the armpit skin is loose, so it is difficult to clamp it
[0004] 2. The reason why the glass thermometer is easy to slip and break
[0005] After family members use the thermometer, they need to pinch and drop it. The known thermometer is straight and has a smooth surface, so there is a problem that it is easy to slip off and break
[0006] 3. The reason why the traditional glass thermometer is easy to burst
It can be considered that the traditional thermometer can no longer meet the actual needs
[0008] 4. Defects of plastic thermometer
So far, it is not possible to fully change clothes and shoes for all patients who visit the hospital. It can be said with certainty that every medical institution has cleaning equipment, but it is difficult to achieve 100% cleanliness and sterility every moment
[0010] (2) Mercury thermometers made of plastic do have anti-drop function, but sooner or later they will oxidize, age, degrade and leak
[0011] 5. Lack of Management on Mercury Leakage Management in Medical Institutions
[0013] 6. Defects of photoelectric sensor temperature detector
[0014] In the early spring of 2003, "atypical pneumonia" suddenly came to my country. The management installed electro-optical temperature sensing equipment in public places and traffic ports. Not only did it have problems of mismeasurement, false alarm and easy failure, but it was also expensive and inconvenient to carry. Difficult to spread to every family
During the SARS period, most schools distributed thermometers, one for each person or house, and the damage phenomenon cannot be counted. The designer also has the experience of crashing the thermometer
[0015] 7. Technical defects of related patents
[0017] (1) The defects of a pediatric thermometer with the patent No. 201220073058.5 are: 1. easy to burst in extreme high temperature weather; Replacement; ③ most of the hospitals are equipped with thermometer drop-off machines (centrifuges), which can drop dozens, hundreds or more at a time; the elastic rubber belt 3 is easy to twist when it is concentrated for drop-off and centralized soaking and disinfection Together, easy to age, less convenient
[0018] (2) The defects of the environmental-friendly mercury thermometer with the patent number 99234228.7 (authorized announcement number: CN2409505Y) are: ① The front end (vacuole) cannot directly contact the skin of the patient's liquid nest, and the protective shell will delay the temperature measurement, and there is a risk of false alarms for indication errors 2. when it slides down, thermometer body (the present invention claims capillary indicating value tube) 4 still can break and leak; 3. there is the problem of bursting in extreme high temperature weather; When the product is finished, the life of the plastic is shorter than that of the glass thermometer, and the rubber seal is inconvenient to replace; ⑤ When the protective shell 1, the connecting belt 3 and the anti-slip finger buckle are made of metal materials, the connecting belt 3 is inelastic and cannot be used for the nurse's on-site activities; The three parts must be put on the thermometer and welded first. Whether the thermometer, especially the liquid bubble, can withstand the temperature during welding needs further research; the glue seal described in this manual is the assembly method between the protective part and the thermometer, not the shell 1. The connection mode between the connecting belt 3 and the non-slip finger buckle 2
[0019] (3) The defect of a kind of underarm mercury thermometer whose patent application publication number is CN103592042A (application number: 201310612961.3) is: 1. Compared with the straight tube thermometer, the mercury in the capillary indicating tube must be dropped into the vacuoles after use , whether it is hand-held drop-off or drop-off with a thermometer, it is not convenient; ② There is also the problem of extreme high-temperature weather, and high-temperature environments are prone to bursting
[0020] (4) The defect of a kind of unbreakable mercury thermometer whose patent application number is 201610750361.7 is: 1. its way of thinking is to prepare that the thermometer will slip, and it will be reinforced so that it will not break when it falls; ② In terms of its production process and preparation method, especially whether the metal temperature-sensing end 3 (mercury bubble) can be tightly connected with the glass thermometer body (capillary display tube) without leakage, and whether it can be industrially produced at one time, Further research is needed; ③The aging of the soft rubber layer 15 will lead to a high scrap rate of the overall thermometer; ④It is still a straight tube shape, and it is still easy to drop when pinched and squeezed
[0021] (5) The defect of the new mercury thermometer with sulfur powder with the patent No. 201620627668.3 is: the thermometer is broken and processed passively, it is better to let the thermometer not slip, break and lose
[0022] (6) Patent No. 201420400623.3 is a protective device for preventing glass mercury thermometers from shifting, and its defects are: ① the negative pressure suction cup at the end of the electrocardiogram lead (especially the negative pressure value of the negative pressure suction cup of the new electrocardiogram machine is relatively high , the negative pressure ball above the negative pressure suction cup of the old machine will lose its elasticity after long-term use and repeated squeezing) The time for adsorption on the chest wall is usually about one minute. If it is too long, it will cause skin bruises like cupping
In particular, the skin of infants is thin and tender, and the time to measure the temperature of the patient is usually 5 to 10 minutes. As stated in paragraph [0007] of the patent specification, if the patient or nurse temporarily forgets..., it will bring harm to the skin of the patient, especially the infant. ; ②If the protective cover 3 is fixedly connected to the tail of the thermometer, it is inconvenient to replace, centralized disinfection and centralized drop-off; when students queue up for physical examination, they find that the seven or eight lead wires on the electrocardiogram machine are often twisted together and delay time, let alone dozens of How about one, hundreds or more thermometers being soaked and disinfected together and dropped with a thermometer dropping machine? ! ③If the protective sleeve 3 is still easy to slip due to the flexible connection, this is because the capillary indicating tube is straight and has a smooth surface
[0023] (7) The defects of the unbreakable mercury thermometer with the patent application number of 2013 1016 1478.8 are: ① There is a problem that it is easily contaminated by pathogenic bacteria on the ground after slipping; And the protective bracket 3 is an organic transparent material, which is easy to age, which will lead to a high scrap rate of the whole thermometer; if it is transparent glass, it is still easy to break
[0024] (8) The defect of the shatterproof thermometer whose patent No. is 2016 2020 5863.7 is: (see paragraphs [0024] and [0025] of the manual) the glass bubble (vacuole) is the thinnest and most likely to crash part of the thermometer, and its protective cover 4 only protects the Vitreous body 1, does not protect glass bulb 2
[0025] (9) The defect of the anti-drop thermometer with the patent No. 2009 2026 8811.4 is: ① it is inconvenient to press the thermometer continuously after the slider 2 is pushed out to measure the temperature, otherwise the thermometer 4 will be retracted into the jacket 3 , the moment the nurse puts the thermometer into the patient's armpit and releases the finger, the thermometer will be withdrawn; the phalanx in the finger is in the shape of a round rod, which is rigid and soft, and the armpit and armpit are a nest, so it is difficult to compress and compact the slider 2..., plus the orientation of the slider 2 in the armpit, is it facing outward, inward, upward or downward? ! And the thickness of the subcutaneous fat of the patient..., so there is a risk of false measurement and false alarm; ②The thermometer cannot be sterilized at high temperature. It is a plastic spring, which will be aged and brittle after several years of heat and cold changes and oxidation; in the normal temperature environment and under the condition of careful use, the life of the glass thermometer is unlimited, and the spring iron 1 and the thermometer 4 are fixedly connected and inconvenient to replace;③ There are many components and the preparation process is cumbersome
[0026] (10) The defect of a mercury thermometer whose patent number is 2015 2046 9262.2 (see paragraph [0009], [0010] and attached figure 1 , 2 ) is: ①It cannot prevent the thermometer from slipping and crashing. This is because when the body temperature is detected, the mercury head (vacuole) of the thermometer body is exposed outside the protective cover 2, just like a badminton falling. The ball is smaller and heavier. The air resistance is small. Landing; ②The exposure and reset of the vacuole must be manually operated, which is troublesome
[0027] (11) Defects of the pediatric thermometer whose patent number is 2015 2004 9510.8 (see paragraphs [0014] and [0027] and attached figure 1 ) is: ① the mercury storage area (vacuole) 7 protrudes out of the shell 5 and retracts into the shell 5. Manual operation is required, so when the thermometer slips from the armpit, it cannot prevent the vacuole from crashing; ② children, especially infants, have small armpits , the thermometer is large, which will cause discomfort in children; ③When measuring body temperature, the patient's armpit skin should be tightly wrapped around the vacuole. Since the shell 5 is wide and thick, the armpit skin will be stretched, which will cause the outer surface of the vacuole to not be completely or tightly packed. Contact with the skin; measured from the overall technique, it is not suitable for temperature measurement in children
[0028] (12) The common feature of the above-mentioned patent applications or patented technologies is that most of them add some protective devices to the traditional thermometers, and do not make significant improvements to the structure or shape of the thermometers
