Description
本发明涉及一种负压装置，特别是涉及一种带压力显示的负压装置。The present invention relates to a vacuum device, and more particularly to a vacuum device with a pressure display.
临床上有多种场合需要使用负压装置进行取样、治疗，但负压装置一般凭肉眼无法判断装置内的压力情况，是否处于已经失压或压力过大状态。There are many occasions in clinical use of negative pressure devices for sampling and treatment, but the negative pressure device is generally unable to judge the pressure inside the device by the naked eye, whether it is in a state of being out of pressure or excessive pressure.
由于负压装置的应用场合特殊，装置的负压对取样量和安全性有着直接的影响。因此，负压装置需要有监测装置内或装置使用时的压力的功能。Due to the special application of the vacuum device, the negative pressure of the device has a direct impact on the sampling volume and safety. Therefore, the negative pressure device needs to have a function of monitoring the pressure inside the device or when the device is in use.
常见的负压装置有真空采血管、负压引流器、电动吸引器等，少部份为设备，多为一次性产品。一次性用品的负压装置，容量往往有限，一般的真空采血管的负压一般仅够采集2～10ml血液，负压引流器的负压一般也就采集1000ml左右的引流液。电动设备可持续吸引，但因为压力仪表往往是放在主机上，吸引时并不方便观察压力情况。Common vacuum devices include vacuum blood collection tubes, vacuum suction devices, electric suction devices, etc., and a small number of devices, mostly disposable products. The negative pressure device of disposable articles often has a limited capacity. Generally, the vacuum pressure of the vacuum blood collection tube is generally only enough to collect 2 to 10 ml of blood, and the negative pressure of the negative pressure drainage device generally collects about 1000 ml of drainage liquid. Electric equipment can be attractively attracted, but because pressure gauges are often placed on the mainframe, it is not convenient to observe the pressure when it is attracted.
以普通的一次性真空采血管为例，真空采血管基本由管体和封闭管体的装置构成，放置时间越长，负压减少或完全失效的机率越高，因为缺乏相应的显示装置，临床护理人员使用前不能判断其是否有效。临床用于儿童、新生儿、老年患者、急危重病人或者外周循环不足的病人时，往往很难超量采血，但又需满足检验用血量的最低要求，
这时需要精准采血。如因误用负压不足的负压装置造成采血量不足，不仅增加病人痛苦、延误检查和加大护理人员的工作量，在某些情况下还会引起医患纠纷。Taking an ordinary disposable vacuum blood collection tube as an example, the vacuum blood collection tube basically consists of a tube body and a device for closing the tube body. The longer the placement time, the higher the probability of negative pressure reduction or complete failure, because of the lack of corresponding display device, clinical The caregiver cannot judge whether it is effective before use. When clinically used in children, newborns, elderly patients, critically ill patients, or patients with insufficient peripheral circulation, it is often difficult to over-collect blood, but it must meet the minimum requirements for blood supply for testing.
At this time, accurate blood collection is required. If the negative pressure device caused by the misuse of negative pressure causes insufficient blood collection, it not only increases the patient's pain, delays the examination and increases the workload of the nursing staff, but also causes doctor-patient disputes in some cases.
以现行真空采血管为例，基本上底部为半球形。临床上为方便确定真空采血管已经采集到液体的量，普遍只有单侧一排刻度，是按水平位来设置，但临床实际往往为倾斜30～60度角抽血，多为45度角，当抽取了相应容量的血液时，不能在抽血时读取水平刻度，只能再次把采血管竖立，方可从刻度上进行读取。医务人员会因对位、手部移动等原因，往往不能保持标准的采血位置或读数位置。Taking the current vacuum blood collection tube as an example, the bottom portion is substantially hemispherical. Clinically, it is convenient to determine the amount of liquid that has been collected in the vacuum blood collection tube. Generally, there is only one row of scales on one side, which is set according to the horizontal position, but the clinical practice is often to draw blood at an angle of 30 to 60 degrees, mostly at a 45 degree angle. When the corresponding volume of blood is drawn, the horizontal scale cannot be read while the blood is being drawn, and the blood collection tube can only be erected again before being read from the scale. Medical staff may not be able to maintain a standard blood collection position or reading position due to alignment, hand movement, and the like.
在生产企业生产真空采血管后，因生产环境真空度不足、贮存或运输过程操作不当等情形，均有可能出现失压现象。现行需抽检测定方可明确失压环节，对质量监控带来不便，且抽检后该采血管就会失效，造成不必要的浪费。After the production of vacuum blood collection tubes in production enterprises, the pressure loss may occur due to insufficient vacuum in the production environment and improper operation in the storage or transportation process. The current need to test the prescription can clear the pressure loss link, which brings inconvenience to the quality control, and the blood collection tube will fail after the sampling, resulting in unnecessary waste.
