Abstract
The invention relates to a medicine box collision locking mechanism for a portable infusion pump. The medicine box collision locking mechanism is composed of a pump body, a medicine box, a lock pin, a latch handle rotating shaft, an operation latch handle and a compression spring. Two sides of the medicine box are provided with a clamping hook and a through hole respectively. The latch handle rotating shaft and the operation latch handle are fixedly connected together to be installed on the pump body and can rotate around the pump body. The latch handle rotating shaft is sleeved with the lock pin and the compression spring. One end of the compression spring is blocked by a baffle fixed on the pump body, the other end of the compression spring and the lock pin can slide back and forth along the axial direction of the latch handle rotating shaft. Mutually matched positions of the latch handle rotating shaft and the lock pin are provided with a convex helical surface and a concave helical surface respectively. Compared with existing products, the medicine box collision locking mechanism reduces operation difficulty and operation steps, and product usability is obviously improved. The possibility of making a mistake by operators is also reduced simultaneously, and product safety is improved.
Description
Technical field
The present invention relates to infusion pump in medical application, especially the medicine box of portable infusion pump collision locking mechanism.
Background technology
The one of the main reasons of malpractice is the faulty operation due to operator, and the ease for use of medical device product not good be lead to errors operation an immediate cause.A vital factor must considering while updating medical device product ease for use and be design.
Infusion pump in medical application is usually used in medicine or medicament to inject in patient body.Portable infusion pump coordinates medicinal box special to use conventionally.The medicine box of medicinal liquid of substituting the bad for the good during use need to reliably be arranged on the pump housing.Common medicine box mounting means is to rotarily drive hook tension by shank of the key.During operation, first medicine box to be fastened on to the corresponding installation site of the pump housing, then rotate shank of the key on the pump housing and drive the hook medicine box that furthers, make it be fitted in pump housing mating surface and the hook structure holding position by appropriate design locks, finally complete the installation of medicine box.Yet the ease for use of this mounting means is unsatisfactory.The necessary hand grip pump housing of operator during operation, another hand grip medicine box, before medicine box is not locked, two handss all can not loosen, but also need to rotate with hands the action that shank of the key completes locking simultaneously, in fact operator often hands complete promptly simultaneously and rotate two actions of shank of the key.Some product even also need to rotate respectively in both sides two shank of the keys and complete locking action, has so at least needed three actions just can complete, so ease for use is not good.
Summary of the invention
In order to overcome the deficiency of the medicine box locking mechanism ease for use of existing portable infusion pump, the present invention has designed the medicine box collision locking mechanism of portable infusion pump, this mechanism only needs two handss of operator to firmly grasp respectively the pump housing and medicine box when medicine box is installed, fastening can complete installation locking action mutually, and ease for use obviously promotes.In addition, during release, only need stir gently handle and can take off medicine box, operate also very convenient.
The technical solution adopted for the present invention to solve the technical problems is:
The medicine box collision locking mechanism of portable infusion pump, described medicine box collision locking mechanism is comprised of the pump housing, medicine box, lock pin, shank of the key rotating shaft, operation shank of the key and stage clip.There are respectively a snap fit feature and a through hole feature in described medicine box both sides.Described shank of the key rotating shaft and described operation shank of the key firmly link together and are arranged on the pump housing and can rotate around the pump housing.Described lock pin and described compression spring sleeve are contained in described shank of the key rotating shaft.The baffle plate that described stage clip one end is fixed on the pump housing stops, the other end can axially slidably reciprocate along described shank of the key rotating shaft with together with described lock pin.There are respectively epirelief and recessed helicoid in described shank of the key rotating shaft and the described lock pin place of cooperatively interacting.
When medicine box is installed, first the snap fit feature of medicine box one side is fastened to the corresponding recessed installation site of the pump housing, then medicine box opposite side is compressed to the pump housing.Medicine box first promotes lock pin and compresses stage clip in compaction process, and then when lock pin is just in time aimed at the through hole feature of medicine box opposite side, lock pin is upspring and completed locking through through hole by stage clip.
While taking off medicine box, rotating operation shank of the key drives shank of the key rotating shaft rotation, by the helicoid cooperatively interacting, promotes lock pin compression press spring, and the through hole that lock pin is departed from medicine box completes release.
The invention has the beneficial effects as follows, when being installed, medicine box only needs two handss of the operator promptly pump housing and medicine box mutually fastening respectively, only need an action can complete installation locking action, compare and reduced operation easier and operating procedure with existing product, the ease for use of product is obviously promoted.Also the probability that operator makes mistakes, the safety that has improved product have been reduced simultaneously.
