Abstract
The utility model provides a disposable sucking head for a haemoglobin pipet, having a conical sucking head body. The back end of the sucking head body is provided with a trepan boring which is convenient for to be sheathed with the head of a haemoglobin pipet, the front end of the sucking head body is provided with a sucking boring, and the trepan boring and the sucking boring are communicated with each other. When the utility model is used, the sucking head is sheathed with the head of the haemoglobin pipet, the haemoglobin pipet is not directly contacted with the wound of a patient, and the sucking head can be replaced once after the blood of every patient is collected every time, so that the occurrence of crossing infection can be avoided. The sucking head which has low price is easy for large-scale bulk production, and can satisfy the requirement of disposable use in hospitals.
Description
This utility model relates to the instrument that supplies laboratory and hospital inspection to use, and uses when being particularly suitable for taking blood sample.
Blood is the body fluid tissue of each organ of contact whole body, by blood circulation, has linked up the contact between each organ-tissue, the any histoorgan generation of body pathological changes all can directly or indirectly influence the change of blood constituent, therefore, to the check of blood, have important medical diagnosis and be worth.When laboratory and hospital inspection blood, need take a small amount of blood sample for general, micropipet is high especially as its utilization rate of accurate measurer of drawing blood sample to be measured, owing to will stinging wound with patient needle, hemoglobin straw in blood collection procedure directly contacts, if reuse, very easily cause cross infection, relevant hygiene department of country once stipulated for this reason, must a people one manage, promptly a hemoglobin straw can only be used for adopting blood sample one time, perhaps takes must just can reuse through the strict sterilization sterilization behind the blood sample.But in real work, be difficult to reach this requirement, its reason is that the hemoglobin straw of (1) 20 μ L belongs to fine measuring instrument, its capacity accurately whether, accuracy influence to laboratory test results is bigger, if adopt a large amount of hemoglobin straw blood samplings, because its corrected value is all inequality, be difficult to guarantee the accuracy of blood sampling volume; (2) the cost eighteenth of the twenty of hemoglobin straw is expensive, if do disposable use, increases a lot of financial burden will inevitably for patient and hospital; (3) consumption is too big, and each hospital must have a large amount of hemoglobin straws could have enough to meet the need use; (4) disinfect difficulty, elongated glass tubing very easily damages in the process of disinfecting, the unsuitable autoclave sterilization of rubber bulb.For these reasons, understand most of hospitals all not according to the predetermined operation of " people one pipe ", only do routine disinfection after each blood sampling and handle, continue then to reuse, therefore often have the case of cross infection to take place, cause suffering to patient with the ethanol cotton balls according to me.The purpose of this utility model provides the problem that the disposable tip that uses on the hemoglobin straw prevents cross infection and the above-mentioned existence of solution that is enclosed within.
Hemoglobin straw disposable tip described in the utility model has a suction nozzle body, is characterized in that suction nozzle body rear end has to be convenient to and the belled trepanning of hemoglobin straw head, and suction nozzle body front end has one and inhales the hole, trepanning with inhale the hole and be interconnected.
Hemoglobin straw described in the utility model with disposable tip preferably design be that the suction nozzle body is conical, has the outer setting of the rear end of trepanning that rib is arranged, so that extract.
Adopt hemoglobin straw described in the utility model to have bigger economic benefit and social benefit with disposable tip, its advantage is that (1) suction nozzle is socketed in the hemoglobin straw head, only suction nozzle might contact wound, everyone just can abandon suction nozzle the back of at every turn taking a blood sample, after same hemoglobin straw changes a suction nozzle, just reusable, not only avoid the generation of cross infection, and guaranteed the accuracy of each blood sampling volume; (2) the cheap manufacturing of suction nozzle is easy, is suitable for doing disposable use, and the expense of increase is extremely low, can mass industrialized production; Can satisfy each hospital of the whole nation and breadboard needs; It is quick and convenient to extract suction nozzle when (3) using, even under the numerous situation of patient, also can operate according to " people one suction nozzle ", helps the healthy of patient.
With reference to the accompanying drawings this utility model is described in further detail.

With reference to Fig. 1～2, hemoglobin straw disposable tip described in the utility model, one suction nozzle body 1 is arranged, the rear end of suction nozzle body 1 has trepanning 2, the size of trepanning 2 and shape so that extract conveniently with hemoglobin straw head 3 is advisable, the front end of suction nozzle body 1 has one and inhales hole 4, and trepanning 2 and suction hole 4 are interconnected.Hemoglobin straw described in the utility model with disposable tip better implement scheme is, suction nozzle body 1 is conical, trepanning 2 also is conical, suction nozzle body 1 can be selected nontoxic rubber for use, and plastic or other material is made, and utilizes the elasticity of material, can make the good socket of head of suction nozzle and hemoglobin straw and be convenient to take off, in addition, also can rib 5 be arranged during fabrication, be more convenient for extracting suction nozzle like this in the outer setting of the rear end of suction nozzle body 1.During use suction nozzle is socketed in the hemoglobin straw head, hemoglobin straw and patient's wound is isolated take blood sample, a people one suction nozzle has been avoided the generation of cross infection.
