The drain bottle stand that a kind of zero point is adjustable
Technical field
This utility model relates to technical field of medical instruments, specifically, is adjustable drain bottle stand at a kind of zero point.
Background technology
EVD art and lumbar subarachnoid PTBD are the most frequently used operation techniques of department of neurology.By giving Intraventricular or lumbar subarachnoid placing drainage, external drainage bottle is with drainage of cerebrospinal fluid and intracranial pressure.Take ventriculus tertius as zero point, liquid level namely is approximately intracranial pressure with respect to the height at zero point in the external ventricular drainage bottle during intracranial pressure.Clinically the patient is put down when crouching, bilateral external auditory meatus line mid point is approximately the ventriculus tertius level.The postoperative drainage bottle is extremely important with respect to the height of external auditory meatus, and it is not enough to place too high then drain, and it is excessive to place too low then drain, especially when the lumbar subarachnoid catheter drainage, places too low even the risk that causes transforminal herniation is arranged.
At present, the method for the most frequently used fixedly drainage bottle is to place a drip stand in that bed is other clinically, by the range estimation drainage bottle with respect to the fixing drainage bottle of the height of external auditory meatus.Like this, can not accurately determine dead-center position, also can't the flat height of Accurate Determining liquid.In addition, because the neurological patient needs the frequent changes position, the different nursing care personnel are also different for the estimation of zero point and the flat height of liquid during the position change, finally all may cause drain deficiency or drain excessive.In addition, drain bottle stand after also having some to improve, for example Chinese patent literature CN 200720030786.7, and open day 2008-08-06 discloses a kind of brain drainage bottle holder, comprise base, column, fixation clamp and carriage, it is characterized in that: the central vertical of base fixedly is equipped with establishes graduated column, and the clamping bar cover is equipped with in activity on the column, and clamping bar puts and has screw and the clamping bar bolt is housed, clamping bar puts and is provided with clamping bar, and fixation clamp is equipped with in the end of clamping bar; The carriage cover is equipped with in activity on the column of clamping bar cover top, and carriage puts and has screw and bracket bolt is housed, and carriage puts and is provided with carriage, and the drainage bottle guardrail is housed on the carriage, and this brain drainage bottle holder can be adjusted the position height of drainage bottle as required.Chinese patent literature CN 200920253415.4, open day 2010-08-11, a kind of brain drainage bottle holder is disclosed, by fixing clamp, support bar, bottle cover forms, it is characterized in that the fixing clamp lower face is provided with fastening bolt, be connected with sleeve on the side plate outer wall, in the sleeve by knob fastening outer wall be provided with the support bar of scale mark, post upper is fixed wtih the bottle cover that barrel is provided with the vertical form of rectangle, its advantage is: drainage bottle is sleeved on fixation in the bottle cover, be difficult for or skew, and can be at any time observe liquid situation in the drainage bottle by form; The drainage bottle height can press height to adjust at any time with patient's cranium, can realize the accurate location of drainage bottle, is conducive to medical personnel to patient's treatment and nursing.But above-mentioned two kinds of conduction bottle fixing racks still can not make things convenient for the adjusting at zero point, to zero point and liquid putting down the estimation of height with randomness, simultaneously be not provided with the vertical reference device, can not guarantee that the drain bottle stand is in vertical state all the time, and then cause the flat elevation measurement accuracy of liquid not high.Therefore in the urgent need to a kind ofly zero point can being regulated conveniently, can keep the drain bottle stand to be in the drain bottle stand of vertical state, but yet there are no report about this class drain bottle stand at present.
