Description
Technical field
The invention relates to a kind of medicine feeder for anesthetic vaporizer, especially be applied to a kind of medicine machine that anesthetis is filled into anesthesia evaporator about a kind of.
Background technology
Existing anesthesia evaporator dosing method generally is divided into two types: 1) directly dosing or through annotating the dosing method of valve funnel dosing; After the dosing of anesthesia evaporator lid opened; The dosing mouth of vaporizer directly poured anesthetis into by the hand-held anesthetis medicine bottle of anaesthetist; After dosing finishes, the dosing lid is tightened sealing; 2) dosing method of connecting device in the middle of the needs; Now commonly used like Quik Fil system on the anesthetic machine that is used for GE and wedge shape filling system (keyed filling); The anaesthetist opens the anesthetis medicine bottle and connects middle connecting device; Then the dosing lid of anesthesia evaporator is opened, perhaps the wedge of drug feeding device is extracted out, connecting device is to drug feeding device in the middle of connecting; Carry out dosing through middle connecting device again, recover the dosing lid or the wedge of drug feeding device after dosing finishes again.
Directly the dosing method of dosing is very convenient, can and not lose and can't dosing owing to the damage of middle connecting device, but directly dosing method carries out in the process of dosing the anaesthetist; Anaesthetic has a spot of volatilization, gets into surrounding, after dosing finishes; If the anaesthetist does not tighten the dosing lid; Anaesthetic can occur and leak, the surgical environments around polluting causes narcotic waste and influences medical personnel healthy.
For the dosing method of connecting device in the middle of the band, in the dosing process, the anesthetis volatilization is eased down to minimum degree, but the hidden danger that connecting device damages and loses in the middle of existing, and in case middle connecting device is lost or damaged, dosing can't be carried out.
In sum, an existing volatilization jar drug feeding device has following defective:
1) only has a dosing mouth, can only adopt a kind of dosing method to carry out narcotic perfusion,, just need change vaporizer again and could realize, can not on a volatilization jar, realize multiple dosing method if want to change reperfusion mode;
2) when direct dosing method, as add medicine and do not tighten the dosing lid, then can cause anaesthetic to leak, cause danger;
3) for wedge shape and Quik Fil dosing method, connecting device in the middle of need relying on, if lose or damages in the middle of connecting device, then can't dosing, possibly make the volatilization jar to use.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency of prior art, and a kind of medicine feeder for anesthetic vaporizer that can realize sealing and can realize multiple mode dosing is provided.

The 3rd dosing position: when drug feeding device 5 and second valve block fixed thereon forward Figure 12 and position shown in Figure 13 to when (being illustrated as 3 positions); One second drug-intake cavity 52c of dosing piece is in the plumb position; First drug-intake cavity 12 of first drug-passing hole 32 of the second drug-passing hole 42c of this second drug-intake cavity 52c, second valve block 4, first valve block 3, first connection chamber 22 of connected body 2 and volatilization jar 1 aligns in order and is communicated with; First discharge chamber 13 of first steam vent 33 of the second discharge chamber 53c of this dosing piece 5, the second steam vent 43c of second valve block 4, first valve block 3, second connection chamber 23 of connected body 2 and volatilization jar 1 aligns in order and is communicated with; Can carry out feeding operations through the second drug-intake cavity 52c of this dosing piece 5, realize the dosing of the third dosing method.
For this medicine feeder for anesthetic vaporizer; A volatilization jar coupling assembling has at least one first dosing passage; The dosing block assembly has at least one barrier bodies and at least two second dosing passages, and this dosing block assembly relatively this volatilization jar coupling assembling have at least one sealing station and at least two dosing positions.At any sealing station; The inlet of each first dosing passage of volatilization jar coupling assembling is all blocked by the barrier bodies of dosing block assembly; The first dosing passage and the second dosing passage are not communicated with mutually; Realized the sealing between dosing block assembly and the volatilization jar coupling assembling, reduced the possibility that anaesthetic was revealed when the doctor did not tighten dosing lid or the damage of dosing lid after the dosing, thereby reduced application risk.In arbitrary dosing position, one first dosing passage and one second corresponding dosing channel connection are all arranged, realize the dosing of anaesthetic; Certainly; In arbitrary dosing position; Two or more first dosing passages and corresponding two or more second dosing channel connections also can be arranged; Like two first dosing passages and two the second corresponding one by one connections of dosing passage, and only carry out dosing through one of them first dosing passage and one second corresponding dosing passage thereof.
For this medicine feeder for anesthetic vaporizer, a volatilization jar coupling assembling both can comprise first valve block, also can not comprise first valve block; The dosing block assembly both can comprise second valve block, also can not comprise second valve block, only need make jar coupling assembling motion of can volatilizing relatively of dosing block assembly.
For this medicine feeder for anesthetic vaporizer; The dosing block assembly has at least one barrier bodies and at least two second dosing passages; Thereby can realize at least two kinds of dosing methods, this dosing method can compatible existing keyed filling, Quik Fil, directly dosing and band are annotated dosing methods such as valve funnel mode.Under given conditions; If because of the private adapter of wedge or Quik Fil mode (connecting device promptly) damages or loses the situation that can't use this dosing method that causes; And when causing volatilization jar to use; The doctor can select other mode dosing, thereby has improved the utilization rate of volatilization jar.Each second drug-intake cavity 52a of dosing piece 5,52b, 52c can shared dosing mouths, also can have dosing mouth 54a, 54b, 54c separately.This medicine feeder for anesthetic vaporizer has been realized multiple dosing method and has been deposited.
For this medicine feeder for anesthetic vaporizer, the dosing block assembly is sealed and matched and can be dynamically connected with a volatilization jar coupling assembling, through the relative position of change dosing block assembly with volatilization jar coupling assembling, realizes that the selection of various dosing methods is switched.This dosing block assembly can form revolute pair or moving sets with a volatilization jar coupling assembling.For volatilization jar coupling assembling with first valve block and the dosing block assembly with second valve block, the end face seal of the end face of first valve block and second valve block cooperates, and second valve block can paste the end face rotation or the slip of this first valve block.This first valve block and second valve block can be processed by the material with preferable sealing, when making both relative motioies, still can keep sealing state, and the end face of this first valve block and second valve block can be the plane, thereby is convenient to be sealed and matched.
For this medicine feeder for anesthetic vaporizer, whether be in the plumb position through three second drug- intake cavity 52a, 52b, the 52c that judges the dosing piece, judge that whole drug feeding device is in which kind of sealing station or dosing position, be convenient to the doctor and observe and operation; Also can distinguish sealing station and dosing position through non-plumb position.
For this medicine feeder for anesthetic vaporizer, first valve block can be integrated on the connected body, and second valve block can be integrated on the dosing piece.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
