Description
Technical Field
The invention relates to medical supplies, in particular to a medical needle pulling assembly.
Background
During the medical rescue, a hanging drop is usually involved, and a common drop injection head, see fig. 1, is structured to include a needle a, on which a holding piece b is provided, and an injection tube c is butted to the end of the needle a.
Because the whole infusion time is long, and medical staff can not monitor whether the infusion of a patient is already dripped at any time, when the liquid in an infusion bottle is quickly dripped, if the patient can not find the medical staff once, no accompanying of family people exists around the patient, the mood of the patient can be very irritated at the moment, if the patient chooses to unplug the needle by himself, the patient can only unplug the needle by using another hand without hanging the infusion, although when the infusion is hung at present, a wound plaster is arranged at the position of a needle eye, but when the infusion is hung, the needle is still below the wound plaster, and the patient can necessarily perform the following process when the patient himself unplugs the needle: the needle head is pulled out from the hand of the patient, blood flows out from the space between the adhesive bandage and the needle insertion opening, the patient puts down the needle head and presses the adhesive bandage with the hand, and a great amount of blood necessarily flows out in the process.
After extracting the syringe needle, patient usually can press the needle pricking mouth through another hand of not hanging the bit, if the mouth of this in-process receives the kneading, just can prick near the needle mouth and will appear red and swollen, patient's medical experience is relatively poor.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a medical needle pulling assembly which can realize synchronous needle pulling and adhesive bandage sticking and is further beneficial to improving the medical experience of patients.
The technical purpose of the invention is realized by the following technical scheme: a medical needle pulling assembly comprises a strip-shaped elastic wound belt, wherein the area of the elastic wound belt close to two ends is an adhesion area, an adhesive layer is arranged in the adhesion area, the middle of the elastic wound belt is a gauze area opposite to a wound, a driving area is arranged between the adhesion area and the gauze area, a contraction strip is arranged in the elastic wound belt, the contraction strip is in butt joint with the two adhesion areas in a crossing manner, an air bag is arranged in the driving area, an air tap is arranged on the air bag, an air plug is plugged in the air tap, and a connecting line is connected to the air plug;
still including pulling out the needle spare, it includes the shell to pull out the needle spare, be equipped with the clamping part that is used for the centre gripping syringe in the shell, connecting wire one end is connected with the shell.
Through the technical scheme, in the actual use process, the needle head can be pricked into the back of the hand of a patient, the elastic wound belt is attached to the back of the hand of the patient, two adhesion areas on the elastic wound belt can be adhered to the skin of the back of the hand of the patient, a gauze area of the elastic wound belt is opposite to the pricking point of the needle head, and at the moment, air is filled into an air bag of the driving area, so that the gauze area of the elastic wound belt is separated from the skin of the back of the hand of the patient; when the infusion is hung and the needle needs to be pulled out, a patient only needs to hold the shell, the clamping part clamps the injection tube and moves along the direction departing from the needle point of the needle, the needle pulling piece can pull the needle out of the hand of the patient, the connecting line can pull the air plug, the air plug is separated from the air faucet, the gas in the air bag can leak out, the contraction force of the contraction strip acts on the gauze area, and the gauze area can be tightly attached to the hand back position of the patient pricked by the needle; in the process, two steps of pulling out the needle and attaching the adhesive bandage are basically realized, and the medical experience of the patient is favorably improved.
Preferably, the needle pulling part further comprises two clamping blocks, a sliding channel and a tube penetrating hole are arranged on the shell in a penetrating mode, the two clamping blocks are arranged at two ends of the sliding channel in a sliding mode respectively, the injection tube penetrates through the tube penetrating hole and is located between the two clamping blocks, and the end portion, away from the injection tube, of each clamping block protrudes out of the shell.
Through above-mentioned technical scheme, when needs carry out the centre gripping to the syringe, the patient only needs to exert pressing force to the grip block, and two grip blocks alright move toward the syringe direction simultaneously, and the tip of grip block can produce the clamping action so that drag the syringe to the syringe on the one hand, and on the other hand can produce the current-limiting action to the syringe.
Preferably, a spring is connected between each clamping block and the housing, and the spring force drives the end of the clamping block, which faces away from the syringe, to protrude out of the housing.
Through the technical scheme, after the clamping block generates clamping force on the injection tube and finishes the needle pulling action, the pressing force of a patient disappears, and the elastic force of the spring drives the end part of the clamping block to protrude out of the shell so as to be convenient for secondary use; of course, in the process of using at ordinary times, the end part of the clamping block can be enabled to be always protruded out of the shell, and the clamping block is convenient for a patient to use at any time.
Preferably, the shell is further provided with a first threading hole, the clamping block is provided with a second threading hole, and the connecting line simultaneously passes through the first threading hole and the second threading hole; in the sliding process of the clamping block, the first threading hole and the second threading hole can be in a relative or staggered state.
Through the technical scheme, when a patient presses the clamping block, the first threading hole and the second threading hole are staggered, the connecting wire can be clamped in the shell, and when the shell is pulled, the connecting wire and the air plug can be pulled at the same time; when not pressing the grip block, first through wires hole can be relative with the second through wires hole, has made things convenient for the threading of connecting wire.
Preferably, the number of the air bags and the number of the driving areas are two, and the air bags and the driving areas are symmetrically distributed by taking the gauze area as the center.
Through above-mentioned technical scheme, can control the gauze district more evenly and the distance between the patient back of the hand, and when the gasbag lost qi, the laminating degree of consistency of gauze district and patient back of the hand also can be higher.
