Description
Technical Field
The invention relates to the field of structural design of hemostatic equipment, in particular to a pressure application control system for hemostasis.
Background
At present, most of uremia patients in China rely on hemodialysis to maintain life, wherein about 75 percent of hemodialysis patients adopt arteriovenous internal fistula to carry out hemodialysis. Hemodialysis is still one of the best treatments for uremia patients to date, and arteriovenous fistula is the most important pathway for hemodialysis and can be said to be the 'life line' of hemodialysis patients. The blood vessel that the human body can be used as internal fistula is extremely limited, and the hemodialysis patient is mostly worse in blood vessel condition due to the pathological changes of the blood vessel and the influence of blood drawing, venous transfusion and the like in the long-term medical treatment process. Each time the fistula is spent, a "life path" is lost. However, because the needle for puncture of the hemodialysis internal fistula is thick, the needle placement maintenance time is long, and the intra-venous pressure is high due to the gradual arteriolization of the postoperative vein of the internal fistula, especially for a hemodialysis patient with a poor self blood coagulation mechanism, under the conditions of puncture errors, insufficient hemostasis time after puncture or improper hemostasis compression force, the internal fistula puncture point of the hemodialysis patient can be caused to bleed or complications of the internal fistula can be caused. The life span and maintenance of internal fistulas is critical, however, since hemodialysis can last as long as thirty years. Hemodialysis patients with serious illness need frequent hemodialysis (three times a week or two times a week), and after the needle is pulled out after the dialysis is finished each time, correct compression of hemostasis points and compression force are important links for protecting internal fistula, and the service life of next dialysis and blood vessels can be directly influenced.
Currently, compression tourniquets are generally used clinically for hemostasis after puncture of autologous arteriovenous internal fistula of the hemodialysis patient. The structure of the traditional compression tourniquet is formed by respectively sewing a first woven barbed strip and a second woven barbed strip at two ends of an elastic band. For the traditional compression tourniquet, the clinical application operation is that a cotton ball pillow is firstly placed on the reverse side of an elastic band of a woven barbed strip at one end, the cotton ball pillow is pressed on the puncture point part of the internal fistula by hands, the elastic band is wound on a limb (such as a forearm) of the puncture point part of the internal fistula by the other hand, and then the woven barbed strips at the two ends are lapped and buckled, so that the purpose of fixing and stopping bleeding is achieved. During hemostasis, since the internal fistula must maintain smooth blood flow to avoid complications, the tourniquet must be released regularly during the period of time (about 1 hour) when hemostasis is compressed by the internal fistula. At present, the releasing operation of the conventional compression tourniquet is usually to peel off and separate two woven barbed strips pressed together, and then to release the tourniquet at will by an operator, and then to overlap and press the two woven barbed strips for fixation.
Chinese patent (publication No. CN206548570U) discloses a compression tourniquet for arteriovenous internal fistula puncture site, which is particularly used for compression hemostasis of the arteriovenous internal fistula puncture site of a blood vessel when hemodialysis patient finishes treatment. The patent comprises a fixing band used for surrounding the arm of a patient so as to realize a bundling type fixing operation, wherein a compression air bag which can be inflated and deflated is arranged on the fixing band at the puncture point of the arm of the patient; a soft cushion layer is also clamped between the compression air bag and the skin of the patient, a placing hole for plugging and fixing a sterile cotton ball is arranged on the soft cushion layer in a penetrating way, and the puncture point position of the arm of the patient is positioned in the hole type range of the placing hole.
Although, this patent possesses repeatedly usable, use cost low and aseptic hemostasis by compression's advantage, after every dialysis treatment finishes and pulls out the pjncture needle, slowly relaxs the decompression again when oppressing 20 ~ 30 minutes to effectively guarantee the even hemostasis by compression effect of puncture point. However, the tourniquet at the arteriovenous internal fistula puncture position provided by the patent has great difficulty in bundling or tightness adjustment by one hand, and is difficult to finish by one patient; moreover, because the sterile cotton ball is arranged in the soft cushion layer, the problem that the position of the compression point is inaccurate due to uneven pressure applied by the compression air bag because the elastic coefficients of the sterile cotton ball and the soft cushion layer are different exists; meanwhile, if the sterile cotton balls need to be replaced, the sterile cotton balls can be removed after the binding is released, and the medical staff needs to assist the binding again. Therefore, the technical problem to be solved by the present invention is to provide a pressure application control system for hemostasis against the above-mentioned deficiency.
Moreover, on the one hand, since the skilled person in the art who is understood by the applicant is necessarily different from the examination department; on the other hand, since the inventor made the present invention while studying a large number of documents and patents, the disclosure should not be limited to the details and contents listed in the specification, but the present invention should not have the features of the prior art, but the present invention should have the features of the prior art, and the applicant reserves the right to increase the related art in the background art at any time according to the related specification of the examination guideline.

Preferably, the pressure sensor 20 and the wound monitor 21 are also disposed on the lower surface of the pressure applying capsule 3, and the central processing module 22 is disposed on the bottom surface of the inner side of the tourniquet lid. Because the existing hemostatic device only has the function of dressing and hemostasis, the wound cannot be monitored, and doctors or patients cannot know the bleeding condition and infection of the wound through the hemostatic device. The wound monitor 21 provided by the invention is used for monitoring the change of the environment around the wound in a non-contact way, so that the monitoring effect on the wound bleeding is realized. Because the process of wound healing is that platelets and collagen form thrombus to play a role of hemostasis firstly, and then leukocyte infiltrates to carry out inflammatory reaction to prevent infection, blood vessels expand at the time, blood circulation increases, tissue regeneration is carried out to heal gradually, inflammatory reaction occurs in the process of wound healing, blood circulation also increases, and the pathological manifestations of inflammatory reaction are red, swelling, thermal pain and the like, wherein heat is the manifestation of temperature increase, so that the body temperature of a wound is higher than that of other places, a wound monitor 21 such as a temperature sensor can be used for monitoring the area near the wound, at the moment, under the condition that the temperature is obviously increased, the information is output to a central processing module 22, alarm information is output to a prompt module 23 by the central processing module 22, and the prompt module 23 plays a countermeasure to a patient through sound prompt information, the hemostatic tablet 1 is prompted to call medical staff or needs to be replaced by other dressings with the anti-inflammatory function, and the hemostatic tablet is also suitable for the technical field of wound care.
